PiMP Guide to xmr-stak, a cryptonight miner for nvidia, amd, and cpu.

[Anjin]

xmr-stak mines the cryptonight family of algorithms. Currently

👉Cryptonight - ETN, DERO, XAO,...
👉Cryptonight V7 - XMR, XTL,...
👉Cryptonight Heavy - SUMO, XHV, LOKI...
👉Cryptonight Lite V7 - AEON
👉Cryptonight IPBC V3 - IPBC!

It runs on both Nvidia and AMD GPUs, as well most CPUs out there. Supports these coins and many others:

Aeon, Bbscoin, Bitcoal, Croat, Dero, Dinastycoin, Edollar, Electroneum, Fonero, Graft, Haven, Intense, Interplanetary Broadcast Coin, Italocoin, Iridium, Karbo, Leviarcoin, Loki, Masari, Monero, Ombre, Solace, Stellite, Sumokoin, Superioir, Turtlecoin, Ultranote,...

Read up on the release pages here:

To get it going with PiMP, first do a pimpup to be sure you have the latest code.

Next install miner 3201 using pimp --add 3201

3201 (cpu/amd/nvid) xmrstak v2.4.5 (pimp2.5.1+): cryptonight [xmrstak.pcfg]

Now edit the configuration file. Find a good profile stanza that matches the coin you wish to mine, and edit it to match your details. Remove the # at the front of a stanzas lines to enable it. Here is an example:

 # MoneroPool with Local Wallet: Username is YOUR_WALLET.YOUR_WORKER/YOUR_EMAIL
 #  POOL1=stratum+tcp://mine.moneropool.com:3333
 #  USER1=4AkxPmLWKtyQ7hagDJ3CMRevKUvtDpe8XcABaJRYfXvLHCWFtyChdxhMNXuhEpp6aPXgg7AEpFSRCEAHqNhkBuP66qqVNP1.PimpWorker
 #  PASS1=x

Modify this as required, with your wallet in USER, and your pool URL in POOL, then remove all the leading # marks.

# MoneroPool with Local Wallet: Username is YOUR_WALLET.YOUR_WORKER/YOUR_EMAIL
 POOL1=stratum+tcp://mine.moneropool.com:3333
 USER1=4AkxPmLWKtyQ7hagDJ3CMRevKUvtDpe8XcABaJRYfXvLHCWFtyChdxhMNXuhEpp6aPXgg7AEpFSRCEAHqNhkBuP66qqVNP1.PimpWorker
 PASS1=x

Now test fly the configuration using pimp --test In this case, my profile id is 3

#pimp --test 3

It is wise to read the guides for xrm-stak well. As a miner, it provides a wide range of configurable options. To get the best performance out of any given set of GPUs, you will want to do your research. After running it the first time, you will find a set of config files in the miners directory at /opt/miners/xmr-stak. Each of the config files end in .txt. For example, nvidia.txt sets up the configuration for NVIDIA GPUs.

Please reply to this thread with any configs you discover that perform well. Make sure you note the configuration of the system, as well post the entire JSON entry from the config file. Using gputool will also benefit you greatly.

Benchmarks with XMR-Stak

After setting up and starting the miner, you should be able to get pretty live updates using Miner.farm. You can also attach to the screen session using screen -d -r as normal.

Let the miner run for awhile, at least a few minutes. This will insure it has settled in nice. In the screen session, simply hit the h key, and it will report the utilization for you. The format spans a couple rows, so read across the output for the full result. You should also check with your pool. Remember that pools won't show results until blocks have matured, based on the rules of each pool.

There is also a CLI option for --benchmark BLOCKVERSION. You can enable this mode by adding the line to FLAGS in your profile. Or simply run the miner from the shell by hand using /opt/miners/xmr-stak/xmr-stak --benchmark BLOCKVERSION. If you use your profile, you should only run the miner using the debug mode from pimp. Make sure you remove the option after getting numbers for your platform.

You can also tweak the GPU settings with gputool while the miner is running. Make a change and apply it with gputool, and check the results on Miner.farm or by hitting h in the screen window. Let changes soak 10~15 minutes to validate stability.
