CPU Mining With the cpuminer-opt Free and Open Source Miner

21, May 2020

It has been a while since we last covered the cpuminer-opt software, but the good news is that its development hasn’t stopped and this should probably be your go to miner as far as CPU mineable crypto coins are concerned. Do note that cpuminer-opt is an open source mining software for processor mining that supports a lot of algorithms and that list is growing, though you will most likely be using just a couple of them nowadays. The miner has optimizations for older and newer AMD and Intel processors, so make sure you try the binary that is intended for your processor for best results or feel free to experiment.

The alternative that often comes handy as far as CPU mining is concerned is SRBMiner-MULTI that supports fewer CPU mining algorithms, but some of them could be more optimized compared to cpuminer-opt, and also has support for RandomX algorithms (mostly targeted at AMD Ryzen CPU miners). SRBMiner-MULTI however is also a closed source miner with a built-in developer fee, even if it is a verified and a trusted one, some people still prefer to use open source mining software only s far as crypto and not only is concerned.

Have in mind that cpuminer-opt is available as a pre-built and ready to be used binary only for Windows, it has its source code available for everyone, has no developer fees of any kind and is supported only with donations, so if you find it useful fee free to toss some coins to your friendly software developer JayDDee (joblo) on Bitcointalk to the following Bitcoin address: 12tdvfF7KmAsihBXQXynT6E6th2c2pByTT.

CPU Mining With cpuminer-opt 3.8.4 the Yescryptr32 Algo for WAVI

19, Mar 2018

It has been a while since we have last CPU mined a crypto coin that only has a CPU miner and not a GPU or ASIC and uses a new crypto algorithm, it has been a while since we have used the cpuminer-opt as well. So why not get back to it and put some stress on your processor for mining using the latest cpuminer-opt 3.8.4 (download) and mine WAVI coins (Bitcointalk announcement) that use the new yescryptr32 algorithm.

If you are interested in what kind of performance you can expect mining this algorithm with a CPU, here is a reference for you. An Intel Core i7 6850K (6-cores at 3.6 GHz + HT) does around 635 H/s in the yescryptr32 algorithm without overclock of the processor. A processor like the commonly used Intel Celeron G1840 (Dual Core at 2.8 GHz) manages to get around 110 H/s in terms of hashrate when mining yescryptr32. If you try mining WAVI coins with a different processor feel free to share your performance results in the comments below…

Windows Binaries for the cpuminer-opt 3.3.8 CPU Miner

24, Jul 2016

cpuminer-opt-3-3-8

Another update in the form of a Windows binary compiled from the latest cpuminer-opt (source) CPU miner with added optimizations for many algorithms using the AES-NI instruction set (also works on older SSE2 capable CPUs). Up until recently the cpuminer-opt was available only for Linux users, but starting from version 3.3 there is also Windows support and we have compiled 64-bit binaries of the miner for Windows for the latest released version 3.3.8. The latest update brings some performance improvements such as blake2s with about 10% higher hashrate, support for new algorithms such as LBRY, Whirlpool and WhirlpoolX as well as fixed Skein2 that was apparently broken in the previous version.

In the archive below you can find multiple executable files that are compiled for different CPU architectures that support AES-NI instructions, so you are welcome to try them to see what works best for you. If your processor does not support AES-NI (CPUS introduced 5 or more years ago), then you might want to use the cpuminer-sse2.exe binary. The default cpuminer.exe is compiled for Intel Westmere, the first Intel architecture that has support for the AES-NI instruction set and cpuminer-amd.exe is bdver1 which should work on all AMD processors with AES-NI support. If you have a more recent Intel Sandybridge, Ivybridge, Haswell or Broadwell-based processor you can try the respective binary to see if that will squeeze some extra performance, or you can compile directly on your PC with the native instruction set supported by your CPU.
