A bit late with this one, but better late than never. We have compiled a 64-bit Windows binary of the new cpuminer-multi fork by ocminer (source) with support for the HMQ1725 algorithm used by Espers (ESP). We have made small source changes in order to use hmq1725 as algorithm name instead of quark in the original source and compiled generic binaries for AMD and Intel CPUs that seem to provide a bit higher hashrate than the Windows binary provided by ocminer. We have tried compiling with optimizations for specific CPU architectures, but since it did not produce noticeable performance increase we are sticking to the generic ones for AMD K8 or newer as well as Intel Core 2 or newer processors. Running some tests on an Intel 5820K CPU has resulted in about 135 KHS with ocminer’s binary and our Windows binaries are giving us about 150 KHS, so they should be around 10% faster, but you are welcome to try and report your results.

Some people have asked is there is a CPU miner for Decred (DCR), well it turns out there actually is – a version of tpruvot’s cpuminer-multi CPU miner (source) with added support for the Blake-256 14-rounds algorithm used by Decred and support for getwork as the coin does not shave support for stratum for the moment. We have compiled a Windows 64-bit binary for the miner that you can download and try below if you are interested in mining Decred with CPU, although there might not be much point in doing so based on the performance you should expect to bet getting out of the CPU miner. Currently Decred (DCR) has a very high network difficulty and slow block times, so it is not easy to mine with GPU, let alone with CPU. Trying out the CPU miner we are getting around 1.55 MHS per thread on a Intel Core i7 5820K (6 cores 12 threads) for a total of about 18 MHS versus 1.2+ GHS from a GTX 970 or 280X GPU. Still if you want to experiment CPU mining Decred (DCR) you can do so with this miner.

We have not released binary updates of the cpuminer-multi CPU miner fork from tpruvot with multiple algorithms support (source), so here is an up to date version compiled for Windows. This is the most functional fork of cpuminer that comes with support for the largest number of algorithms and a lot of optimizations for them to get the most performance out of your CPU. Do note however that some dedicated forks of cpuminer for a specific algorithm may still provide better performance, but if you want flexible solution with many algorithms supported then cpuminer-multi is the choice. We have compiled an up to date Windows binary from the latest source that comes with some fixes and improvements for various algorithms as well as support for some new algorithms such as bastion, scrypt-jane, sib and yescrypt. If you have some spare CPU power that you want to use for mining then this is the miner you’ll need, do note that we have compiled our Windows binary with Visual Studio 2013 and for 64-bit Windows.
