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](https://github.com/xmrig/xmrig-nvidia) and [AMD GPU version]( https://github.com/xmrig/xmrig-amd). * [Roadmap](https://github.com/xmrig/xmrig/issues/106) for next releases. #### Table of contents * [Features](#features) * [Download](#download) * [Usage](#usage) * [Algorithm variations](#algorithm-variations) * [Build](https://github.com/xmrig/xmrig/wiki/Build) * [Common Issues](#common-issues) * [Other information](#other-information) * [Donations](#donations) * [Release checksums](#release-checksums) * [Contacts](#contacts) ## Features * High performance. * Official Windows support. * Small Windows executable, without dependencies. * x86/x64 support. * Support for backup (failover) mining server. * keepalived support. * Command line options compatible with cpuminer. * CryptoNight-Lite support for AEON. * Smart automatic [CPU configuration](https://github.com/xmrig/xmrig/wiki/Threads). * Nicehash support * It's open source software. ## Download * Binary releases: https://github.com/xmrig/xmrig/releases * Git tree: https://github.com/xmrig/xmrig.git * Clone with `git clone https://github.com/xmrig/xmrig.git` :hammer: [Build instructions](https://github.com/xmrig/xmrig/wiki/Build). ## Usage Use [config.xmrig.com](https://config.xmrig.com/xmrig) to generate, edit or share configurations. ### 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 --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 -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-access-token=T access token for 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 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 enables SeLockMemoryPrivilege for current user, but reboot or sign out still required. [Manual instruction](https://msdn.microsoft.com/en-gb/library/ms190730.aspx). ## 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 instruction set. * Try setup optimal cpu affinity. * Enable fast memory (Large/Huge pages). ## Donations * XMR: `48edfHu7V9Z84YzzMa6fUueoELZ9ZRXq9VetWzYGzKt52XU5xvqgzYnDK9URnRoJMk1j8nLwEVsaSWJ4fhdUyZijBGUicoD` * BTC: `1P7ujsXeX7GxQwHNnJsRMgAdNkFZmNVqJT` ## Release checksums ### SHA-256 ``` 232af0c5f3b1cdbc2d90b514873a764b434d5621d2790da67954b35c17e44fe3 xmrig-2.6.0-beta2-xenial-amd64.tar.gz/xmrig-2.6.0-beta2/xmrig 2366a06729d4de538ef511862bf11d0c7ad40fd245e7aeab3c1957307d63471a xmrig-2.6.0-beta2-gcc-win32.zip/xmrig.exe 2f6538c765e001d13ca380cbc1558d51efcb97d4bccdfa40993cb872be4e9efd xmrig-2.6.0-beta2-gcc-win64.zip/xmrig.exe 3c0479acb78a3cee8fe416ee438dbff09c786acf50fbaf28a820127fcd0c6e62 xmrig-2.6.0-beta2-msvc-win64.zip/xmrig.exe ``` ## Contacts * support@xmrig.com * [reddit](https://www.reddit.com/user/XMRig/)
