Usage

Basic example

xmrig.exe -o xmr-eu.dwarfpool.com:8005 -u YOUR_WALLET -p x -k

Options

  -a, --algo=ALGO       cryptonight (default) or cryptonight-lite
  -o, --url=URL         URL of mining server
  -b, --backup-url=URL  URL of backup 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
      --no-color        disable colored output
      --donate-level=N  donate level, default 5% (5 minutes in 100 minutes)
  -B, --background      run the miner in the background
  -c, --config=FILE     load a JSON-format configuration 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
  -h, --help            display this help and exit
  -V, --version         output version information and exit

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

i7-6700 - 290+ H/s (4 threads, cpu affinity 0xAA)
Dual E5620 - 377 H/s (12 threads, cpu affinity 0xEEEE)

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).
