XMRig
XMRig is high performance Monero (XMR) CPU miner, with the official full Windows support. Based on cpuminer-multi with heavy optimizations/rewrites and removing a lot of legacy code.

Usage
Basic example
xmrig.exe -o xmr-eu.dwarfpool.com:8005 -u YOUR_WALLET -p x -k
Options
-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
-h, --help display this help and exit
-V, --version output version information and exit
Build
Ubuntu (Debian-based distros)
sudo apt-get install git build-essential cmake libcurl4-openssl-dev
git clone https://github.com/xmrig/xmrig.git
cd xmrig
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make
Windows
It's complicated, you need MSYS2, custom libcurl build, and of course CMake too. Configure options for libcurl:
./configure --disable-shared --enable-optimize --enable-threaded-resolver --disable-libcurl-option --disable-ares --disable-rt --disable-ftp --disable-file --disable-ldap --disable-ldaps --disable-rtsp --disable-dict --disable-telnet --disable-tftp --disable-pop3 --disable-imap --disable-smb --disable-smtp --disable-gopher --disable-manual --disable-ipv6 --disable-sspi --disable-crypto-auth --disable-ntlm-wb --disable-tls-srp --disable-unix-sockets --without-zlib --without-winssl --without-ssl --without-libssh2 --without-nghttp2 --disable-cookies --without-ca-bundle
CMake options:
cmake .. -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DCURL_INCLUDE_DIR="c:\<path>\curl-7.53.1\include" -DCURL_LIBRARY="c:\<path>\curl-7.53.1\lib\.libs"
Common Issues
HUGE PAGES unavailable
- Run XMRig as Administrator.
- Enable SeLockMemoryPrivilege. For Windows 7 pro, or Windows 8 and above see this article.
Other information
- Now only support 64 bit operating systems (Windows/Linux).
- 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).
