XMRig

⚠️ Monero will change PoW algorithm on October 18, all miners and proxy should be updated to v2.8+ ⚠️

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

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

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
      --variant            algorithm PoW variant

      --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
  -S, --syslog             use system log for output messages
      --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/xmrig-proxy support
      --print-time=N       print hashrate report every N seconds
      --api-port=N         port for the miner API

      --api-worker-id=ID   custom worker-id for API
  -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

• av option used for automatic and simple threads mode (when you specify only threads count).
• For advanced threads mode each thread configured individually and av option not used.

av	Hashes per round	Hardware AES
1	1 (Single)	yes
2	2 (Double)	yes
3	1 (Single)	no
4	2 (Double)	no
5	3 (Triple)	yes
6	4 (Quard)	yes
7	5 (Penta)	yes
8	3 (Triple)	no
9	4 (Quard)	no
10	5 (Penta)	no

Common Issues

HUGE PAGES unavailable

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

Other information

• No HTTP support, only stratum protocol support.
• Default donation 5% (5 minutes in 100 minutes) can be reduced to 1% via 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 instruction set.
• Try setup optimal cpu affinity.
• Enable fast memory (Large/Huge pages).
