Discuss - cpuminer-opt v3.11.3 - open source optimized multi-algo CPU miner | Kiếm Tiền Trên Mạng - Make Money Online

“This is the home of cpuminer-opt, the optimized CPU miner.”

Supporting over 90 agorithms with many optimized for CPUs with the latest technologies:

  • AMD Ryzen: AVX2, SHA
  • Intel Skylake X: AVX512
  • Intel Icelake: AVX512, SHA, and VAES (source code only at this time)

Unique features

  • Block and share time estimates.
  • True hashrate reporting with comparison with actual share submission rate.


New in v3.11.3
Fixed x12 AVX2 again.
2. More speed for allium: AVX2 +4%, AVX512 +6%, VAES +14%.
3. Restored lost speed for x22i & x25x.

A x86_64 architecture CPU with a minimum of SSE2 support. This includes Intel Core2 and newer and AMD equivalents.
In order to take advantage of AES_NI optimizations a CPU with AES_NI is required. This includes Intel Westmere and newer
and AMD equivalents. Further optimizations are available on some algos for CPUs with AVX and AVX2, Sandybridge and
Haswell respectively.
32 bit CPUs and ARM CPUs are not supported.

2. 64 bit Linux 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.
64 bit Windows OS is supported using the pre-compiled binaries package or may be compiled with mingw_w64 and msys.
Apple and Android operating systems are not supported. FreeBSD YMMV.
Older CPUs, other architectures and operating systems may be supported by TPruvot’s cpuminer-multi.

Security warning

  • Miner programs are often flagged as malware by antivirus programs. This is usually a false positive, they are
    flagged simply because they are cryptocurrency miners. However, some malware has been spread using the
    cover that miners are known to be subject to false positives. Always be on alert. The source code of cpuminer-opt
    is open for anyone to inspect. If you don’t trust the software don’t download it.
  • Some cryptographic code has been taken from trusted sources but has been modified for speed at the expense of
    accepted security practices. This code should not be imported into applications where secure cryptography is


  • Old algorithms that are rarely used anymore will not get the latest optimizations.
  • Cryptonight and variants are no longer supported.
  • Neoscrypt crashes on Windows, use legacy version.
  • Hodl requires a CPU with AES, use legacy version if without.
  • Benchmark testing does not work on several algos.
