All About BTC, LTC, ETH mining as well as other alternative crypto currencies
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.
There is now a new fork of sgminer 5.0 beta that brings Whirlpool algorithm support for mining crypto currencies such as Whirlcoin on AMD-based GPUs. The new fork by a user called uraymeiviar (source) and it brings a nice hashrate improvement over the previously available sph-sgminer fork by djm34. We have compiled a windows binary from the new source and have already tested it on an AMD Radeon R9 280X GPU, the result we got was 9400 KHS, so about twice as fast than previously in terms of hashrate. You can download and try the windows binary yourself from the link below. Do note that this version of sgminer also supports most other new algorithms, so you an use it for mining not only Whirlpool coins, but others as well. Also make sure to be using the latest 14.6/14.7 beta drivers from AMD in order to get the best performance.
It did not take much time for the AMD miners to also get a GPU miner for the new Whirlpool algorithm and Whirlcoin, the first coin to use it. We now have a sph-sgminer fork with whirlpool support added again thanks to djm34 (source), the guy that just released ccMiner fork with Whirlpool support. We have compiled a windows binary from the latest source and have already tested it on an AMD Radeon R9 280X GPU to see what performance we are going to get – the result was 3300 KHS. You can download and try the windows binary yourself from the link below. Do note that this version of sph-sgminer also supports most other new algorithms as well, so you an use it for mining not only Whirlcoin. Also make sure to be using the latest 14.6/14.7 beta drivers from AMD in order to get the best performance and currently it seems that Nvidia GPU miners have some advantage in terms of performance for this algorithm.
Update: The miner has been updated to include the new updated whirlpool kernel that increases performance. With the new kernel we are getting a boost from about 3300 KHS to about 4750 KHS on a Radeon R9 280X GPU, so definitely worth upgrading if you are mining whirlcoin for example with AMD GPUs. Just redownload the miner to get the updated kernel and take advantage of the significant performance boost for whirlpool algorithm mining.
