Have you read the sidebar and rules? (Please do) Yes. What is your intended use for this build? The more details the better. This i7 920 build was originally a gaming desktop I bought in 2008. In 2015 I built a new Haswell rig to replace it and I have been using this i7 920 machine as an experimental home server where I played with VMs to study for my career in IT. It had run many sorts of workloads including databases (MSSQL, MySQL, PostgreSQL, Oracle), Active Directory servers, Linux LAMP stacks, and bitcoin nodes amongst others on originally ESXi and now Hyper-V hypervisors, and have served me very well throughout the years. I have been feeling the need to have more RAM as I cram more and more VMs into it and I think it is now high time for an upgrade. If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings) I am not looking to game on this build, but I will need good performance for a multiple VM environment. What is your budget (ballpark is okay)? Money is not really an issue but I want to be spending at the right performance/value curve i.e. I do not want to be paying a high price increase for a marginal performance gain. In what country are you purchasing your parts? Malaysia. Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!).

Provide any additional details you wish below. Justifications:
The CPU is in my opinion the best bang for buck right now.
I chose this motherboard because I like Gigabyte and I am now in a financial position to be looking to upgrade the CPU immediately once Zen 3 comes out (no more waiting 5-7 years between builds, hopefully!). Also, USB-C.
Since I won't be overclocking, I am thinking of using Value RAM instead of premium RAMs. However, it seems funny to have Value RAM paired with this kind of motherboard.
32GB sticks, so that I can easily upgrade to 128GB in the future.
The new SSD to make use of PCIe NVME speeds.
Define R6, because HDD bays.
It would be great if I can get your thoughts on this plan. Any feedback is greatly appreciated. Thanks!
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications. Ubuntu http://groestlcoin.org/forum/index.php?topic=441.0
ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
Newbs might not know this, but bitcoin recently came out of an intense internal drama. Between July 2015 and August 2017 bitcoin was attacked by external forces who were hoping to destroy the very properties that made bitcoin valuable in the first place. This culminated in the creation of segwit and the UASF (user activated soft fork) movement. The UASF was successful, segwit was added to bitcoin and with that the anti-decentralization side left bitcoin altogether and created their own altcoin called bcash. Bitcoin's price was $2500, soon after segwit was activated the price doubled to $5000 and continued rising until a top of $20000 before correcting to where we are today. During this drama, I took time away from writing open source code to help educate and argue on reddit, twitter and other social media. I came up with a reading list for quickly copypasting things. It may be interesting today for newbs or anyone who wants a history lesson on what exactly happened during those two years when bitcoin's very existence as a decentralized low-trust currency was questioned. Now the fight has essentially been won, I try not to comment on reddit that much anymore. There's nothing left to do except wait for Lightning and similar tech to become mature (or better yet, help code it and test it) In this thread you can learn about block sizes, latency, decentralization, segwit, ASICBOOST, lightning network and all the other issues that were debated endlessly for over two years. So when someone tries to get you to invest in bcash, remind them of the time they supported Bitcoin Unlimited. For more threads like this see UASF
[META] New to PC Building? - September 2018 Edition
You've heard from all your gaming friends/family or co-workers that custom PCs are the way to go. Or maybe you've been fed up with your HP, Dell, Acer, Gateway, Lenovo, etc. pre-builts or Macs and want some more quality and value in your next PC purchase. Or maybe you haven't built a PC in a long time and want to get back into the game. Well, here's a good place to start.
Make a budget for your PC (e.g., $800, $1000, $1250, $1500, etc.).
Decide what you will use your PC for.
For gaming, decide what games and at what resolution and FPS you want to play at.
For productivity, decide what software you'll need and find the recommended specs to use those apps.
For a bit of both, your PC build should be built on the HIGHEST specs recommended for your applications (e.g., if you only play FortNite and need CPU power for CFD simulations, use specs recommended for CFD).
Here are some rough estimates for builds with entirely NEW parts: 1080p 60FPS ultra-settings modern AAA gaming: ~$1,200 1440p 60FPS high/ultra-settings modern AAA gaming: ~$1,600 1080p 144FPS ultra-settings modern AAA gaming: $2,000 4K 50FPS medium/high-settings modern AAA gaming: > $2,400 It's noted that some compromises (e.g., lower settings and/or resolution) can be made to achieve the same or slightly lower gaming experience within ±15% of the above prices. It's also noted that you can still get higher FPS on older or used PCs by lowering settings and/or resolution AND/OR buying new/used parts to upgrade your system. Make a new topic about it if you're interested. Also note that AAA gaming is different from e-sport games like CSGO, DOTA2, FortNite, HOTS, LoL, Overwatch, R6S, etc. Those games have lower requirements and can make do with smaller budgets.
Revise your budget AND/OR resolution and FPS until both are compatible. Compare this to the recommended requirements of the most demanding game on your list. For older games, you might be able to lower your budget. For others, you might have to increase your budget. It helps to watch gaming benchmarks on Youtube. A good example of what you're looking for is something like this (https://www.youtube.com/watch?v=9eLxSOoSdjY). Take note of the resolution, settings, FPS, and the specs in the video title/description; ask yourself if the better gaming experience is worth increasing your budget OR if you're okay with lower settings and lowering your budget. Note that you won't be able to see FPS higher than 60FPS for Youtube videos; something like this would have to be seen in-person at a computer shop.
After procuring your parts, it's time to build. Use a good Youtube tutorial like this (https://www.youtube.com/watch?v=IhX0fOUYd8Q) that teach BAPC fundamentals, but always refer to your product manuals or other Youtube tutorials for part-specific instructions like CPU mounting, radiator mounting, CMOS resetting, etc. If it everything still seems overwhelming, you can always pay a computer shop or a friend/family member to build it for you. It might also be smart to look up some first-time building mistakes to avoid:
If you have any other questions, use the search bar first. If it's not there, make a topic.
BAPC News (Last Updated - 2018/09/20)
https://www.tomshardware.com/news/intel-9000-series-cpu-faq,37743.html Intel 9000 CPUs (Coffee Lake Refresh) will be coming out in Q4. With the exception of i9 (8-core, 12 threads) flagship CPUs, the i3, i5, and i7 lineups are almost identical to their Intel 8000 (Coffee Lake) series, but slightly clocked faster. If you are wondering if you should upgrade to the newer CPU on the same tier (e.g., i5-8400 to i5-9400), I don't recommend that you do as you will only see marginal performance increases.
https://www.youtube.com/watch?v=WDrpsv0QIR0 RTX 2080 and 2080 Ti benchmarks are out; they provide ~10 and ~20 frames better than the 1080 Ti and also feature ray tracing (superior lighting and shadow effects) which is featured in only ~30 games so far (i.e., not supported a lot); effectively, they provide +25% more performance for +70% increased cost. My recommendation is NOT to buy them unless you need it for work or have lots of disposable income. GTX 1000 Pascal series are still relevant in today's gaming specs.
The calculator part. More GHz is analogous to fast fingers number crunching in the calculator. More cores is analogous to having more calculators. More threads is analogous to having more filing clerks piling more work for the calculator to do. Microarchitectures (core design) is analogous to how the internal circuit inside the calculator is designed (e.g., AMD FX series are slower than Intel equivalents even with higher OC'd GHz speeds because the core design is subpar). All three are important in determining CPU speed. In general, higher GHz is more important for gaming now whereas # cores and threads are more important for multitasking like streaming, video editing, and advanced scientific/engineering computations. Core designs from both AMD and Intel in their most recent products are very good now, but something to keep in mind.
The basic concept of overclocking (OCing) is to feed your CPU more power through voltage and hoping it does calculations faster. Whether your parts are good overclockers depends on the manufacturing process of your specific part and slight variations in materials and manufacturing process will result in different overclocking capability ("silicon lottery"). The downside to this is that you can void your warranties because doing this will produce excess heat that will decrease the lifespan of your parts AND that there is a trial-and-error process to finding OC settings that are stable. Unstable OC settings result in computer freezes or random shut-offs from excess heat. OCing will give you extra performance often for free or by investing in a CPU cooler to control your temperatures so that the excess heat will not decrease your parts' lifespans as much. If you don't know how to OC, don't do it.
Intel CPUs have higher GHz than AMD CPUs, which make them better for gaming purposes. However, AMD Ryzen CPUs have more cores and threads than their Intel equivalents. The new parts are AMD Ryzen 3, 5, or 7 2000 series or Intel i3, i5, or i7 8000 series (Coffee Lake). Everything else is outdated. If you want to overclock on an AMD system, know that you can get some moderate OC on a B350/B450 with all CPUs. X370/X470 mobos usually come with better VRMs meant for OCing 2600X, 2700, and 2700X. If you don't know how to OC, know that the -X AMD CPUs have the ability to OC themselves automatically without manually settings. For Intel systems, you cannot OC unless the CPU is an unlocked -K chip (e.g., i3-8350K, i5-8600K, i7-8700K, etc.) AND the motherboard is a Z370 mobo. In general, it is not worth getting a Z370 mobo UNLESS you are getting an i5-8600K and i7-8700K.
CPU and Mobo Compatibility
Note about Ryzen 2000 CPUs on B350 mobos: yes, you CAN pair them up since they use the same socket. You might get an error message on PCPP that says that they might not be compatible. Call the retailer and ask if the mobo you're planning on buying has a "Ryzen 2000 Series Ready" sticker on the box. This SHOULD NOT be a problem with any mobos manufactured after February 2018. Note about Intel 9000 CPUs on B360 / Z370 mobos: same as above with Ryzen 2000 CPUs on B350 or X370 boards.
CPU Cooler (Air / Liquid)
Air or liquid cooling for your CPU. This is mostly optional unless heavy OCing on AMD Ryzen CPUs and/or on Intel -K and i7-8700 CPUs. For more information about air and liquid cooling comparisons, see here:
Part that lets all the parts talk to each other. Comes in different sizes from small to big: mITX, mATX, ATX, and eATX. For most people, mATX is cost-effective and does the job perfectly. If you need more features like extra USB slots, go for an ATX. mITX is for those who want a really small form factor and are willing to pay a premium for it. eATX mobos are like ATX mobos except that they have more features and are bigger - meant for super PC enthusiasts who need the features.
AMD Ryzen CPUs: go for X470s for Ryzen 7 and B450s for everything else. B350s will also work as a sub for B450 mobos and the same can be said for X370s for X470s, but they are being phased out and may require a BIOS update to support the Ryzen 2000 CPUs if it doesn't have a "Ryzen 2000 Series Ready" sticker on the box.
Intel Coffee Lake CPUs: go for Z370s for unlocked -K CPUs and B360s for everything else.
If you are NOT OCing, pick whatever is cheap and meets your specs. I recommend ASUS or MSI because they have RMA centres in Canada in case it breaks whereas other parts are outside of Canada like in the US. If you are OCing, then you need to look at the quality of the VRMs because those will greatly influence the stability and lifespan of your parts.
Part that keeps Windows and your software active. Currently runs on the DDR4 platform for new builds. Go for dual channel whenever possible. Here's a breakdown of how much RAM you need:
2x4GB = 8GB is the minimum recommended
2x8GB = 16GB recommended for gaming
2x16GB+ for workstations
AMD Ryzen CPUs get extra FPS for faster RAM speeds (ideally 3200MHz) in gaming when paired with powerful video cards like the GTX 1070. Intel Coffee Lake CPUs use up a max of 2667MHz for B360 mobos. Higher end Z370 mobos can support 4000 - 4333MHz RAM depending on the mobo, so make sure you shop carefully! It's noted that RAM prices are highly inflated because of the smartphone industry and possibly artificial supply shortages. For more information: https://www.extremetech.com/computing/263031-ram-prices-roof-stuck-way
Part that store your files in the form of SSDs and HDDs.
Solid State Drives (SSDs)
SSDs are incredibly quick, but are expensive per TB; they are good for booting up Windows and for reducing loading times for gaming. For an old OEM pre-built, upgrading the PC with an SSD is the single greatest speed booster you can do to your system. For most people, you want to make sure the SSD you get is NOT DRAM-less as these SSDs do not last as long as their DRAM counterparts (https://www.youtube.com/watch?v=ybIXsrLCgdM). It is also noted that the bigger the capacity of the SSD, the faster they are. SSDs come in four forms:
2.5" SATA III
M.2 NVME PCI-e
The 2.5" SATA form is cheaper, but it is the old format with speeds up to 550MB/s. M.2 SATA SSDs have the same transfer speeds as 2.5" SATA SSDs since they use the SATA interface, but connect directly to the mobo without a cable. It's better for cable management to get an M.2 SATA SSD over a 2.5" SATA III SSD. M.2 PCI-e SSDs are the newest SSD format and transfer up to 4GB/s depending on the PCI-e lanes they use (e.g., 1x, 2x, 4x, etc.). They're great for moving large files (e.g., 4K video production). For more info about U.2 drives, see this post (https://www.reddit.com/bapccanada/comments/8jxfqs/meta_new_to_pc_building_may_2018_edition/dzqj5ks/). Currently more common for enterprise builds, but could see some usage in consumer builds.
Hard Disk Drives (HDDs)
HDDs are slow with transfer speeds of ~100MB/s, but are cheap per TB compared to SSDs. We are now at SATA III speeds, which have a max theoretical transfer rate of 600MB/s. They also come in 5400RPM and 7200RPM forms. 5400RPM uses slightly less power and are cheaper, but aren't as fast at dealing with a large number of small files as 7200RPM HDDs. When dealing with a small number of large files, they have roughly equivalent performance. It is noted that even a 10,000RPM HDD will still be slower than an average 2.5" SATA III SSD.
SSHDs are hybrids of SSDs and HDDs. Although they seem like a good combination, it's much better in all cases to get a dedicated SSD and a dedicated HDD instead. This is because the $/speed better for SSDs and the $/TB is better for HDDs. The same can be said for Intel Optane. They both have their uses, but for most users, aren't worth it.
I recommend a 2.5" or M.2 SATA ≥ 250GB DRAM SSD and a 1TB or 2TB 7200RPM HDD configuration for most users for a balance of speed and storage capacity.
Part that runs complex calculations in games and outputs to your monitor and is usually the most expensive part of the budget. The GPU you pick is dictated by the gaming resolution and FPS you want to play at. In general, all video cards of the same product name have almost the same non-OC'd performance (e.g., Asus Dual-GTX1060-06G has the same performance as the EVGA 06G-P4-6163-KR SC GAMING). The different sizes and # fans DO affect GPU OCing capability, however. The most important thing here is to get an open-air video card, NOT a blower video card (https://www.youtube.com/watch?v=0domMRFG1Rw). The blower card is meant for upgrading pre-builts where case airflow is limited. For cost-performance, go for the NVIDIA GTX cards because of the cryptomining industry that has inflated AMD RX cards. Bitcoin has taken a -20% hit since January's $10,000+ as of recently, but the cryptomining industry is still ongoing. Luckily, this means prices have nearly corrected itself to original MSRP in 2016. In general:
Part that houses your parts and protects them from its environment. Should often be the last part you choose because the selection is big enough to be compatible with any build you choose as long as the case is equal to or bigger than the mobo form factor. Things to consider: aesthetics, case airflow, cable management, material, cooling options (radiators or # of fan spaces), # fans included, # drive bays, toolless installation, power supply shroud, GPU clearance length, window if applicable (e.g., acrylic, tempered glass), etc. It is recommended to watch or read case reviews on Youtube to get an idea of a case's performance in your setup.
Part that runs your PC from the wall socket. Never go with an non-reputable/cheap brand out on these parts as low-quality parts could damage your other parts. Recommended branded PSUs are Corsair, EVGA, Seasonic, and Thermaltake, generally. For a tier list, see here (https://linustechtips.com/main/topic/631048-psu-tier-list-updated/).
Wattage depends on the video card chosen, if you plan to OC, and/or if you plan to upgrade to a more powerful PSU in the future. Here's a rule of thumb for non-OC wattages that meet NVIDIA's recommendations:
1050 Ti: 300W
1060 3GB/6GB: 400W
1070 / 1070 Ti: 500W
1080 Ti: 600W
There are also PSU wattage calculators that you can use to estimate your wattage. How much wattage you used is based on your PC parts, how much OCing you're doing, your peripherals (e.g., gaming mouse and keyboard), and how long you plan to leave your computer running, etc. It is noted that these calculators use conservative estimates, so use the outputted wattage as a baseline of how much you need. Here are the calculators (thanks, VitaminDeity).
Pick ONE calculator to use and use the recommended wattage, NOT recommended product, as a baseline of what wattage you need for your build. Note that Cooler Master and Seasonic use the exact calculator as Outervision. For more details about wattage, here are some reference videos:
You might also see some info about modularity (non-modular, semi-modular, or fully-modular). These describe if the cables will come connected to the PSU or can be separated of your own choosing. Non-modular PSUs have ALL of the cable connections attached to the PSU with no option to remove unneeded cables. Semi-modular PSUs have separate cables for HDDs/SSDs and PCI-e connectors, but will have CPU and mobo cables attached. Modular PSUs have all of their cables separate from each other, allowing you to fully control over cable management. It is noted that with decent cooling and airflow in your case, cable management has little effect on your temperatures (https://www.youtube.com/watch?v=YDCMMf-_ASE).
80+ Efficiency Ratings
As for ratings (80+, 80+ bronze, 80+ gold, 80+ platinum), these are the efficiencies of your PSU. Please see here for more information. If you look purely on electricity costs, the 80+ gold PSUs will be more expensive than 80+ bronze PSUs for the average Canadian user until a breakeven point of 6 years (assuming 8 hours/day usage), but often the better performance, longer warranty periods, durable build quality, and extra features like fanless cooling is worth the extra premium. In general, the rule of thumb is 80+ bronze for entry-level office PCs and 80+ gold for mid-tier or higher gaming/workstation builds. If the price difference between a 80+ bronze PSU and 80+ gold PSU is < 20%, get the 80+ gold PSU!
Warranties should also be looked at when shopping for PSUs. In general, longer warranties also have better PSU build quality. In general, for 80+ bronze and gold PSU units from reputable brands:
These guys are engineering experts who take apart PSUs, analyze the quality of each product, and provide an evaluation of the product. Another great website is http://www.orionpsudb.com/, which shows which PSUs are manufactured by different OEMs.
Operating System (OS)
The most common OS. You can download the ISO here (https://www.microsoft.com/en-ca/software-download/windows10). For instructions on how to install the ISO from a USB drive, see here (https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/install-windows-from-a-usb-flash-drive) or watch a video here (https://www.youtube.com/watch?v=gLfnuE1unS8). For most users, go with the 64-bit version. If you purchase a Windows 10 retail key (i.e., you buy it from a retailer or from Microsoft directly), keep in mind that you are able to transfer it between builds. So if you're building another PC for the 2nd, 3rd, etc. time, you can reuse the key for those builds PROVIDED that you deactivate your key before installing it on your new PC. These keys are ~$120. However, if you have an OEM key (e.g., pre-builts), that key is tied specifically to your mobo. If you ever decide to upgrade your mobo on that pre-built PC, you might have to buy a new Windows 10 license. For more information, see this post (https://www.techadvisor.co.uk/feature/windows/windows-10-oem-or-retail-3665849/). The cheaper Windows 10 keys you can find on Kinguin are OEM keys; activating and deactivating these keys may require phoning an automated Microsoft activation line. Most of these keys are legitimate and cost ~$35, although Microsoft does not intend for home users to obtain this version of it. Buyer beware. The last type of key is a volume licensing key. They are licensed in large volumes to corporate or commercial usage. You can find lots of these keys on eBay for ~$10, but if the IT department who manages these keys audit who is using these keys or if the number of activations have exceeded the number allotted on that one key, Microsoft could block that key and invalidate your license. Buyer beware. For more information on differentiating between all three types of keys, see this page (https://www.tenforums.com/tutorials/49586-determine-if-windows-license-type-oem-retail-volume.html). If money is tight, you can get Windows 10 from Microsoft and use a trial version of it indefinitely. However, there will be a watermark in the bottom-right of your screen until you activate your Windows key.
If you're interested in using MacOS, look into Hackintosh builds. This will allow you to run MacOS to run on PC parts, saving you lots of money. These builds are pretty picky about part compatibility, so you might run into some headaches trying to go through with this. For more information, see the following links:
Please note that the cost-performance builds will change daily because PC part prices change often! Some builds will have excellent cost-performance one day and then have terrible cost-performance the next. If you want to optimize cost-performance, it is your responsibility to do this if you go down this route! Also, DO NOT PM me with PC build requests! It is in your best interests to make your own topic so you can get multiple suggestions and input from the community rather than just my own. Thanks again.
Here are some sample builds that are reliable, but may not be cost-optimized builds. These builds were created on September 9, 2018; feel free to "edit this part list" and create your own builds.
Updated sample builds to include both AMD and Intel builds
Sorry for the lack of updates. I recently got a new job where I work 12 hours/day for 7 days at a time out of the city. What little spare time I have is spent on grad school and the gym instead of gaming. So I've been pretty behind on the news and some might not be up-to-date as my standards would have been with less commitments. If I've made any mistakes, please understand it might take a while for me to correct them. Thank you!
Although be it that I don't have a complete mastery of the concept either, I will do my best to use my limited knowledge to explain what exactly the heck is going on with this mystical "Litecoin Mining" and the disappearance of AMD GPUs worldwide. What exactly is Litecoin mining? Litecoin mining, or cryptocurrency mining in general, is the use of processors to hash out a value and submit this work in something called "Proof of Work" that is mutually recognized. To put this in an analogy, think of a 3rd grade math classroom. The teacher writes a math problem on the board, say "2+3", and she tells the class to find the answer. Quickly, each student begins to work out the problem, and when a student thinks they've found the answer, they raise their hand and respond, "The answer is 5!". The teacher will then tell the student whether they are right or wrong, and the rest of the class will listen and understand that the one student got the answer right. Then they clap for him, recognizing his achievement and work needed to arrive to the answer. Now, in terms of mining, this difficulty is scaled to immense amounts, but the basic principle is the same. You, the miner, are the student trying to find the answer. The Litecoin master algorithm is the confirming teacher. And the rest of the miners are the other students in the classroom, recognizing your work. Litecoin itself is a derivative of Bitcoin, which is basically another cryptocurrency. Sources: Litecoin Website and Bitcoin (something like Litecoin) So what is so important about this answer? In reality, nothing. It just solves a math problem. But that's all the reason. When the Litecoin algorithm sees you've found the right answer and everybody agrees you found it (so no cheating!), then it will give you a "block reward". Like the teacher handing you a piece of candy for getting the right answer. This block reward contains an amount of Litecoins. What is a "Litecoin"? A Litecoin is a medal or proof of work done, and it is given through the reward system aforementioned. Litecoins are just numerical values stored inside of the "blockchain", which you can think of as the classroom. All of the players of this litecoin mining are located within this classroom, located within the blockchain. When everyone recognizes your work, you are given litecoins, which can only be accessed within wallets. You may think of litecoins as a currency, like pennies or nickels. They are something that we give value, yet do not have inherent value themselves. A paper bill is just paper unless we give it value. So what is a wallet? Wallets are where litecoins are stored, using a private key and a public key. This private key is a hash of base 58 that is completely randomized, such that only knowing both the private and public keys allows access to this wallet. The public key is shared with others who want to send you litecoins, while you keep the private key to yourself, which allows you to spend those litecoins. Now, the ultimate question: Why are they taking our graphics cards?! Ah yes. Now to talk about AMD GPUs. Litecoins use the scrypt algorithm, a memory and computation intensive algorithm that requires many cores and lots of fast RAM. Graphics cards fit both of these profiles perfectly. A graphics card has hundreds or thousands of computation cores, as well as lightning fast GDDR5 memory. As such, graphics cards are snatched up by miners wanting to create money out of thin air, which is basically what they're doing. But why AMD? Why not NVIDIA? AMD graphics cards are more efficient at moving bits than NVIDIA graphics cards, further explained here. All you really have to know if that the AMD architecture is much more efficient for cryptocurrency mining. But why NOW? Bitcoin/Litecoin has been around for awhile. Why are miners stealing our graphics cards NOW? Well, to put it bluntly, it's because people want to get rich. Recently, as further adoption by companies and the media coverage of cryptocurrencies, Litecoin price has skyrocketed. I'm talking magnitudes of 100 fold. Due to this rapid increase in value, miners have been rushing for more graphics card to make more money. If you take a look at this source, you can see that cryptocurrency mining profitability is insanely high compared to Bitcoin, which is Litecoin's main competitor. Look at the right column in the table that says "Profit Ratio vs. BTC". See the numbers in the 3000% range. Yeah, that's a lot of profitability that can be taken advantage of. Will we ever get our beloved 7950s back here in /buildapc? Q_Q Maybe. Delving deeper into what is litecoin, I'll now explain difficulty. As you find more of these answers, with more students working to find the answer to a math problem, the teacher must create more and more difficult math problems for the students to solve, else these little 3rd graders will solve them faster than the teacher has enough candy for. In litecoin mining, this equates to difficulty level. As the difficulty increase, litecoins are harder to hash out, and the rewards diminish. As more students/miners join the blockchain, mining will start to get less and less profitable. HOWEVER. If the price of litecoin skyrockets again, mining will be able to sustain profitability, and we may be out of AMD graphics card for a LONG, LONG TIME. Not to mention, once litecoin becomes unprofitable, if it indeed does, miners will move to other derivatives of cryptocurrencies, restarting the cycle and continuing to snatch up graphics cards. It is unlikely that this trend continues, but if it does, NVIDIA may be the only option for new gamers. Give me a TL;DR summary! I'll try my best. Poor people are sitting in a basement making money of out thin air using our graphics cards. They are making $12 a day per graphics card by basically only paying for electricity. This trend will continue for quite some time, meaning no more AMD graphics cards for a while. If you're a gamer, look towards NVIDIA, or be prepared to throw down a lot of cash. I obviously did not cover EVERYTHING in this post, but the main principles are there. If you want to delve deeper into this, I'd suggest doing your research and looking on the Bitcoin Forum. EDIT: Please check out /litecoin and /litecoinmining as well. Lots of good information.
I've had enough of my rx 480 screwing me over... upgrading to a GTX 1060 or perhaps something else?
After two full days of attempting to fix my PC, I've come to the seeming conclusion that it's a hardware problem. Repeated and consistent BSODs, typically atikmpag.sys, though sometimes IRQL or other video related ones are occuring. It's not software - three times I've safe-mode DDU clean uninstalled AMD drivers and reinstalled the drivers. I even did a clean windows install. It's not the motherboard or CPU - the machine runs fine with the graphics card removed. It's not the cable or monitor - BSODs occur on every monitor I try, HDMI, VGA and DVI. It's not the registry - I increased tdrdelay to 8 seconds and then 16 seconds and it still occurs. It's probably not the power supply - I've undervolted and underclocked the card only to experience BSODs still. As I narrow it down forum post by forum post, I've come to the conclusion: the rx480 is a POS. I guess it's time to bite the bullet and hop over to Nvidia's well supported 1060s, which since the bitcoin crash are more affordable than ever. What is your intended use for this build? The more details the better. Gaming and browsing, no weird video/streaming shit. Here's the games I (might) play, graded in general by demand on the GPU:
Company of Heroes 2
League of Legends
Ass Creed Origins/Ultimate
If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings) 60fps minimum on the games I play. As you can see only a few of these games are particularly demanding (the last few), and I'm perfectly comfortable playing on low/medium settings to achieve 60fps for that. The rx 480 in the early part of its life could sometimes manage these (and to be sure, it was also dependent on the rather shitty optimisation of PUBG/GTA), but can no way achieve them now. So just having that consistency is enough for me. What is your budget (ballpark is okay)? Already have the pieces. No more than £250, but I see 1060s available for around £140. Therefore it's more about value for money and long-term considerations than the money itself right now. In what country are you purchasing your parts? UK PCPartPicker Part List
Current parts ^ Provide any additional details you wish below. So the question I've really got is: based on the info provided so far (500W power supply, decent RAM, decent processor, somewhat limited gaming), should I play it safe with the GTX 1060? Or is there something more suitable for me, like a 1080TI? I'm not familiar with the Nvidia series, so any help is greatly welcome. Thanks.
Questions post! (Newbie miner) Also potential build included at bottom.
Important note: I have tried searching for most of these questions, and as for earnings, the only things I can find are people from 2014-2015 saying that GPU mining is dead, and on the other topics, it's all very vague or overly complex answers which my brain can't wrap itself around. So hopefully this post won't be totally trampled, as I will probably ask some really stupid question. Bear in mind, I recently discovered bitcoin mining about 10 days ago. Since then I've had some good replies from a miner on another subreddit, and he assures me that GPU mining is now back in action. This is ofcourse dependent on power prices, but with my 0.04$ kW/h, I was all good. At first I didn't wanna go all-in with this, but seeing Bitcoin rise in prices, and being personally very sure that it'll keep rising, I'm more intrigued to up the ante. I'll also try and update this post as it goes along with "yes/no" answers, as/if they get answered. So, here we go! First off, I wanted to ask questions in regards to Bitcoin mining and GPU mining. Personal opinions are of course welcome.
Is GPU mining still viable? I've already been told by one person that it is, but would like to hear other people's opinion.
Will Bitcoin mining become harder and less profitable in the near (2-3 years) future? The reason I ask this, is because I've read that only the chinese with the best ASIC's can keep earning money today, and for them, it also becomes harder every day, and they earn less and less. Hopefully this isn't true.
As the price of Bitcoin goes up (if it does), will NiceHash mining become more and more profitable?
In this next section, I wanna dive a bit more into NiceHash, and what it is exactly. From what I've read, it basically rents out your hashing power, so you're not really mining, despite the program being called "miner".
Is there something I missed there, or is that correct? Are you just renting out your hashing power?
If the above is right, does NiceHash always rent out your hashing power to whatever is most profitable?
What exactly is Lbry, Lyra2REv2, Pascal, Equihash etc.? Are they pools? Algorithms?
Say I go to the profibility calculator, and I see that Lyra2REv2 is the most profitable for my GPU, at 39.5%. Does this then mean that I should pick only that in my NiceHash algorithm settings? Or should I pick the ones who are at 29.8% (Lbry) and 23.8% (Equihash) aswell? Does that increase my gains?
If the last one above was correct, would it then be best to check the calculator daily, and only select the algorithm that earns the most based on %?
Is the NiceHash profitability calculator correct, or is it just very rough estimates? Can I really earn 1220$ worth in Bitcoin over 1 year on my GTX 1080ti? (disregarding Bitcoin price changes ofcourse)
Now I'd like to delve more into my own calculations, what I have per today, and what I would like to try out. I'm very glad if you could point out some huge flaws in my plan, and crush my dreams. I would appreciate that a lot more than just letting me try it and loosing tons of capital. Obviously, if there's a question of just risking it, I'll take this decision myself. But helpful input is always welcome! My GPU, daily profit, power cost etc.
GTX 1080ti FE
Daily profit: 5-8$
Power cost: 0.04$ (I live in Norway)
Environment: Humid, cold, lot of wind
Living area: Above ground "basement"
So I don't know if all of the above matters, but that's at least something to go by. From what I can understand, these are good conditions. Correct me if I'm wrong. I was curious as to what I could earn if I built a proper dedicated rig for pure GPU mining. So I went to a popular website we use called Komplett.no and checked out some prices. Here's what I got. Bear in mind that these are all new parts with at least 2 year warranty and 5 year customer warranty.
Mobo: ASUS Prime Z270-P, Socket-1151 (146$)
Picked this MOBO as you could have up to 8 (?) GPU's connected to it with some nifty connectors.
CPU: Intel Celeron G3930 Kaby Lake (60$)
Just found whatever CPU that was cheapest.
RAM: Crucial DDR4 2133MHz 4GB x2 = 8gb (85$)
Cheapest I could find for the MOBO.
SSD: Kingston A400 120GB 2.5" SSD (70$)
Also the cheapest. Could probably find something even cheaper on our "craigslist" but I guess it's best to have a new warranty.
PSU: Corsair AX1200, 1200W PSU (403$)
From what I understand, AX is platinum rated, and I assume this would be best if I'm going to maybe implement more than 2 graphics cards in the future? Or would it be best to buy 2 cheaper gold ones and connect them together? And do you get significant profit increases if you go up in rating? Or is too small to even bother?
GPU: 980GTX x2 on our "craigslists" (475$ for both)
This is probably where I'll have the hardest time deciding. I could go for 1080's, pay more, and earn more. If this was the case, I would also be able to buy them new with a warranty on them. The decrease in value would also not be as big as with 980's. But is it worth it? I can get 1080's used for around 595$, and probably around 540$ if I haggle a little bit. Total: 1239$ for the 980 SLI build. According to the profitability calculator, this will earn me 2440$ per year before taxes, electricity bills etc. Biggest question is then: Is this total bogus, or is it roughly correct if Bitcoin stays at the price it is today/rises? So that's all I have up until now! I haven't seen any post this long on this subreddit yet, so if this is considered "spam" or "2much" please feel free to delete it and toss me a warning. I'm just very excited about GPU mining, and instead of posting questions every day and so forth, I'd rather just ask everything in one post :) Thanks for reading, and have a nice day!
You know it started out innocent enough. One friend at work started talking innocently about Monero and before I knew it I had hooked the work PC up to Minergate and had started mining. After I day I saw Moneros slowly ticking in and felt that it needed to go faster, so I downloaded the client as well on my gaming PC at home, but I wasn't able to use the graphic card, the Moneros were still ticking in at a too slow rate. I did some more reading and found out that Minergate was the devil, that the way to go about this was to set up my own wallet and mine using a client, directly toward a pool. First I created a web-wallet, but then I remember MtGox and all the trouble with bitcoins being lost, so I created a shell wallet on my file server at home and downloaded a few clients, compiled, compared, tuned and after a while I started to see some real Monero dripping in. I managed to get the NVidia miner up on my gaming rig with the juicy 980Ti card and that really made the difference, but I wanted more. I work with grid solutions/high performance computing and at work we have a lab where I can basically set up whatever equipment that I want (within reason) and latch on to work's power grid. I decided to set up a dual GPU system and just leave it running in the lab area where we have the consoles and do general close proximity work to make things work in the real lab. I did not have a casing so I ordered everything I needed and after some troubleshooting (BIOS did not support the Kaby Lake CPU) I got things up and running on 2xRX480 cards, nicely hashing in on about 630H/s on each card. In the mean time, to maximize my Monero flow I had turned every device, work and private into CPU and GPU miners, every clock tick squeezed for maximum utilization and at one point I even ran clients on useless Raspberry PIs, slow file servers and Beagle Bone Internet of Things cards, yielding no more than 3-6 H/s. It all added up, but I still needed more. I started looking into building a real mining rig. I ordered an AMD Motherboard, more PSUs, CPU, RAM, USB risers, etc. and I got a rig frame flown in from China at a reasonable price. In the meantime I had already ordered another RX480 which were idling on my work desk while I was building the rig. The rig was being set up at my work desk, sitting next to my work PC which also was mining Monero at full capacity when I wasn't at work. GPU mining needs to be off if the system is to be used without severe graphics lag. I had installed 2 GPU clients on my home system as well, one that really bogged down the system, rendering it unusable for anything except mining, the other setting I could easily do other work, web-browsing and such without too much lag from the graphic cards. Whenever I left for work or went to sleep I put the heavy load version on, and when I got home from work or woke up in the morning, my living room was warm and cozy, at least 4-5'C above the usual. By now I had gathered 5 GPUs which had completely filled up my mining rig. Achievement unlocked! Although I still had some debugging work to do on it (random crashes) it still would run smoothly most of the time. The Monero is pouring in, about $10 USD worth of Monero each day, from both my rig and the myriad of fileservers, gaming and work PCs, and stupid little devices that were designed for completely different things. The value of Monero had increased from about $12 USD to $30 USD during this time, everything was with a promising outlook. Then, yesterday it occurred to me, I did move 2 cards from the first PC that I bought, to the mining rig, which means that I could get two new cards and put into that one. So, I have just ordered myself two more RX480 (which by the way are much nicer for Monero mining than the RX580s) and as I am sitting here, having just ordered those cards, I am already planning the next step, moving the first motherboard out of the PC and latch it on to a rig and connect 2 more cards (it's a mATX motherboard with 4 PCI-e slots) But now, I am wondering, where will this all end? Have I become a Monero mining addict? How many rigs and graphic cards do I need to finally feel satisfied? When do I get enough? And will this short term bankrupt me completely? Well, at least I am not using money on booze, drugs or hookers, but it still feels like an addiction. Any words of advice or comfort appreciated...
A good news for everyone. GPU price drop in 2018. Finally, you can see and buy one at a reasonable price in India. For a long time, the price of a graphics card keeps on increasing due to which it was impossible for someone to build a custom PC over pre-built PC’s. Because both of them cost exactly same for a certain specification. Let me give you a brief, the launch price of Gtx GeForce 1070 is INR. 35,000 but due to hike & hype the price rises up to INR 50,000 which is an increase of 15%. WHAT DOES A GRAPHICS CARD DO? Basically, a GPU (Graphics processor unit) is a microprocessor specialized for video calculation. It will take a load of video calculation from your computer & calculate if for you so, that your CPU can run and do other tasks more effective & efficiently. Graphics card has a much faster RAM and the processor which help it to do the certain task like games, video rendering etc more productively. WHY HIKE IN PRICE? Before addressing how much drop & supply is now available on the market. Let us see why price hiked in the first place. The main reason for the hike in the price of GPU’s is Cryptocurrency & Cryptomining -Cryptocurrency mining, or crypto mining, is a process in which transactions for various forms of cryptocurrency are verified and added to the blockchain digital ledger. Also known as crypto coin mining, altcoin mining, or Bitcoin mining (for the most popular form of cryptocurrency, Bitcoin), cryptocurrency mining has increased both as a topic and price of GPU because for a while now GPU’s are the necessary equipment for mining. And there are also some other things like less production, company strategies in it. WHY GPU PRICE DROP IN INDIA? AND BY HOW MUCH? There are several reasons for the GPU price drop. The main area is following:- SAIC (Specialized application integrated chip) Overflow of cards 11th series GPU cards SAIC (Specialized application integrated chip) – It is a hardware feature for the people who want to do a specific work like mining. These chip help miners to do crypto mining. It is a specific specialized chip made for performing mining work more effectively than a graphics card. And it is now available in every market. Therefore all the miner are moving towards this hardware. Because it has more life, can do more & it cost cheaper than a graphics card. The overflow of cards – Due to SAIC hardware and less demand of GPU in the market. The companies now have a pile of GPU’s laying around, plus the old miners are selling their used graphics cards in cheap on e-commerce websites. So, right now the GPU’s like Nvidia GeForce series is available on discount. 11th series GPU cards – There is a confirmation in the market that NVIDIA will release 11th series graphics card on June 11th. It is been 2 years since last launch GPU’s by Nvidia, therefore, they will launch something new this year, that is why they are selling out cheap. WHICH CARD PROVIDE BEST VALUE? If you are on a budget, then you are probably thinking which card will give me the best value for money. So, If you have a budget of 10-15k go with GTX 1050 ti, not with 1050. And I suggest if you are willing to spend some more then skip GeForce 1060 and buy Geforce 1070 or 1070 ti founder edition. Because it will last longer and you can enjoy any title on high setting with more than 60fps. WHAT & WHY FOUNDER EDITION CARD? Founder edition is a card manufactured & retail only by Nvidia. Other cards other than founder edition are called custom cards which are manufactured by other companies like ASUS & MSI. They also have same specification and features sometimes more than Founder edition. So, why founder edition card. The main reason and difference is the heat dispense system inside the founder edition card. In India, not everyone has a fully air-conditioned room hence, therefore, the PC case needed to be properly ventilated. gpu vents And the problem with custom cards is that their fan dispenses all the hot air inside the case itself. While on another hand the Founder edition cards dispense all the air directly outside the case through vents on the left side. If you do not have a cooling problem go with custom cards because they are cheap and sometimes better than FC cards. HOW MANY DROP IN GPU PRICE TRENDS? GPU PRICE TRENDS GPU PRICE TRENDS The price drop is significant almost about 40% you can buy these card now directly from any e-commerce website but some websites are still selling them at hiked prices. So, you can head on NVIDIA India for the best price or MDcomputers.in.
Newbs might not know this, but bitcoin recently came out of an intense internal drama. Between July 2015 and August 2017 bitcoin was attacked by external forces who were hoping to destroy the very properties that made bitcoin valuable in the first place. This culminated in the creation of segwit and the UASF (user activated soft fork) movement. The UASF was successful, segwit was added to bitcoin and with that the anti-decentralization side left bitcoin altogether and created their own altcoin called bcash. Bitcoin's price was $2500, soon after segwit was activated the price doubled to $5000 and continued rising until here we are today at $15000. During this drama, I took time away from writing open source code to help educate and argue on reddit, twitter and other social media. I came up with a reading list for quickly copypasting things. It may be interesting today for newbs or anyone who wants a history lesson on what exactly happened during those two years when bitcoin's very existence as a decentralized low-trust currency was questioned. Now the fight has essentially been won, I try not to comment on reddit that much anymore. There's nothing left to do except wait for Lightning and similar tech to become mature (or better yet, help code it and test it) In this thread you can learn about block sizes, latency, decentralization, segwit, ASICBOOST, lightning network and all the other issues that were debated endlessly for over two years. So when someone tries to get you to invest in bcash, remind them of the time they supported Bitcoin Unlimited.
This way, you will still be able to increase your Bitcoin portfolio. Here’s a great video that explains the ins and outs of building a GPU mining rig if you are a beginner.
