tobwiens/xmrig repository overview

⁠XMRig

XMRig is high performance Monero (XMR) CPU miner, with the official full Windows support. Originally based on cpuminer-multi with heavy optimizations/rewrites and removing a lot of legacy code, since version 1.0.0 complete rewritten from scratch on C++.

• This is the CPU-mining version, there is also a NVIDIA GPU version⁠.
• Roadmap⁠ for next releases.

⁠Usage

⁠Basic example

xmrig.exe -o pool.minemonero.pro:5555 -u YOUR_WALLET -p x -k

⁠Failover

xmrig.exe -o pool.minemonero.pro:5555 -u YOUR_WALLET1 -p x -k -o pool.supportxmr.com:5555 -u YOUR_WALLET2 -p x -k

For failover you can add multiple pools, maximum count not limited.

⁠Options

  -a, --algo=ALGO       cryptonight (default) or cryptonight-lite
  -o, --url=URL         URL of mining server
  -O, --userpass=U:P    username:password pair for mining server
  -u, --user=USERNAME   username for mining server
  -p, --pass=PASSWORD   password for mining server
  -t, --threads=N       number of miner threads
  -v, --av=N            algorithm variation, 0 auto select
  -k, --keepalive       send keepalived for prevent timeout (need pool support)
  -r, --retries=N       number of times to retry before switch to backup server (default: 5)
  -R, --retry-pause=N   time to pause between retries (default: 5)
      --cpu-affinity    set process affinity to CPU core(s), mask 0x3 for cores 0 and 1
      --cpu-priority    set process priority (0 idle, 2 normal to 5 highest)
      --no-huge-pages   disable huge pages support
      --no-color        disable colored output
      --donate-level=N  donate level, default 5% (5 minutes in 100 minutes)
      --user-agent      set custom user-agent string for pool
  -B, --background      run the miner in the background
  -c, --config=FILE     load a JSON-format configuration file
  -l, --log-file=FILE   log all output to a file
      --max-cpu-usage=N maximum CPU usage for automatic threads mode (default 75)
      --safe            safe adjust threads and av settings for current CPU
      --nicehash        enable nicehash support
      --print-time=N    print hashrate report every N seconds
  -h, --help            display this help and exit
  -V, --version         output version information and exit

Also you can use configuration via config file, default config.json. You can load multiple config files and combine it with command line options.

⁠Algorithm variations

Since version 0.8.0.

• --av=1 For CPUs with hardware AES.
• --av=2 Lower power mode (double hash) of 1.
• --av=3 Software AES implementation.
• --av=4 Lower power mode (double hash) of 3.

⁠Common Issues

⁠HUGE PAGES unavailable

• Run XMRig as Administrator.
• Since version 0.8.0 XMRig automatically enable SeLockMemoryPrivilege for current user, but reboot or sign out still required. Manual instruction⁠.

⁠Other information

• No HTTP support, only stratum protocol support.
• No TLS support.
• Default donation 5% (5 minutes in 100 minutes) can be reduced to 1% via command line option --donate-level.

⁠CPU mining performance

• Intel i7-7700 - 307 H/s (4 threads)
• AMD Ryzen 7 1700X - 560 H/s (8 threads)

Please note performance is highly dependent on system load. The numbers above are obtained on an idle system. Tasks heavily using a processor cache, such as video playback, can greatly degrade hashrate. Optimal number of threads depends on the size of the L3 cache of a processor, 1 thread requires 2 MB of cache.

⁠Maximum performance checklist

• Idle operating system.
• Do not exceed optimal thread count.
• Use modern CPUs with AES-NI instructuon set.
• Try setup optimal cpu affinity.
• Enable fast memory (Large/Huge pages).
