cpuminer-opt v3.14.1: Optimized multi algo CPU miner for Windows

cpuminer-opt v3.14.1


cpuminer-opt – это ответвление cpuminer-multi от TPruvot с оптимизациями, импортированными из других майнеров, разработанными Лукасом Джонсом, djm34, Wolf0, pooler, Джеффом Гарзиком, ig0tik3d, elmad, palmd и Optiminer, с дополнительными оптимизациями Джея Ди Ди. Весь код считается открытым и бесплатным. Если у кого-то есть претензии по любому из них, опубликуйте ваше дело на форуме cpuminer-opt Bitcoin Talk или по электронной почте.

GBT and getwork log changes:

  • fixed missing TTF in New Block log,
  • ntime no longer byte-swapped for display in New Work log,
  • fixed zero effective hash rate in Periodic Report log,
  • deleted “Current block is…” log.

Renamed stratum “New Job” log to “New Work” to be consistent with the solo
version of the log. Added more data to both versions.

Обратите внимание, программы-майнеры часто помечаются как вредоносные программы антивирусными программами. Это не так, они помечены просто потому, что они являются майнерами криптовалюты. Если вы не доверяете программному обеспечению, не используйте его!

cpuminer-opt v3.14.1: Optimized multi algo CPU miner


  1. A x86_64 architecture CPU with a minimum of SSE2 support. This includes Intel Core2 and newer and AMD equivalents. Further optimizations are available on some algoritms for CPUs with AES, AVX, AVX2, SHA, AVX512 and VAES.

Older CPUs are supported by cpuminer-multi by TPruvot but at reduced performance.

ARM and Aarch64 CPUs are not supported.

  1. 64 bit Linux or Windows OS. Ubuntu and Fedora based distributions, including Mint and Centos, are known to work and have all dependencies in their repositories. Others may work but may require more effort. Older versions such as Centos 6 don’t work due to missing features. 64 bit Windows OS is supported with mingw_w64 and msys or pre-built binaries.

MacOS, OSx and Android are not supported.

  1. Stratum pool supporting stratum+tcp:// or stratum+ssl:// protocols or RPC getwork using http:// or https://. GBT is YMMV.

Many variations of scrypt based algos can be mine by specifying their parameters:

scryptn2: --algo scrypt --param-n 1048576
cpupower: --algo yespower --param-key "CPUpower: The number of CPU working or available for proof-of-work mining"
power2b: --algo yespower-b2b --param-n 2048 --param-r 32 --param-key "Now I am become Death, the destroyer of worlds"
sugarchain: --algo yespower --param-n 2048 -param-r 32 --param-key "Satoshi Nakamoto 31/Oct/2008 Proof-of-work is essentially one-CPU-one-vote"
yespoweriots: --algo yespower --param-n 2048 --param-key "Iots is committed to the development of IOT"
yespowerlitb: --algo yespower --param-n 2048 --param-r 32 --param-key "LITBpower: The number of LITB working or available for proof-of-work mini"
yespoweric: --algo yespower --param-n 2048 --param-r 32 --param-key "IsotopeC"
yespowerurx: --algo yespower --param-n 2048 --param-r 32 --param-key "UraniumX"
yespowerltncg: --algo yespower --param-n 2048 --param-r 32 --param-key "LTNCGYES"


Old algorithms that are no longer used frequently will not have the latest optimizations.

Cryptonight and variants are no longer supported, use another miner.

Neoscrypt crashes on Windows, use legacy version.

AMD CPUs older than Piledriver, including Athlon x2 and Phenom II x4, are not supported by cpuminer-opt due to an incompatible implementation of SSE2 on these CPUs. Some algos may crash the miner with an invalid instruction. Users are recommended to use an unoptimized miner such as cpuminer-multi.

cpuminer-opt does not work mining Decred algo at Nicehash and produces only “invalid extranonce2 size” rejects.

Benchmark testing does not work for x11evo.


Users are encouraged to post their bug reports using git issues or on the Bitcoin Talk forum or opening an issue in git:



All problem reports must be accompanied by a proper problem definition. This should include how the problem occurred, the command line and output from the miner showing the startup messages and any errors. A history is also useful, ie did it work before.


cpuminer-opt has no fees of any kind but donations are accepted.
