All About BTC, LTC, ETH mining as well as other alternative crypto currencies
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.
NiceHash has released an updated version of their Axiom CPU Miner Launcher that provides a simple and easy GUI for running the optimized cpuminer-multi fork (source). The new releases apparently includes optimizations from sandor111 that further increases the performance for mining Axiom on CPU. Compared to the previous version from about a month ago we are seeing about 90% increase in performance on an Intel Core i7 5820K processor and apparently AVX2-capable CPUs seem to have the highest performance increase, though older processors will also get increased hashrate. So if you are mining Axiom on CPU you might want to try the updated miner with GUI to ease the mining on NiceHash and get paid directly in Bitcoin.
