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.

Siamining With New Stratum Mining Protocol for Siacoin

22, Jul 2016

sgminer-stratum-siamining

The Siamining mining pool for Siacoin (SC) we have written about recently has also added Stratum support. Their Stratum implementation however is a bit different from the one that Suprnova has introduced a few days ago for their mining pool and thus requires users to use a different version of sgminer. While the Suprnova Stratum implementation is more of a getwork over Stratum and based on our tests it does perform very well, Siamining is claiming that their solution in true a Stratum support, so in theory it should result in slightly better efficiency. Of course the Siamining mining pool does still support the regular Siacoin Go pool miner that also produces very low percentage of stale shares, though with Stratum support the results should be even better now.

Below you can download a 32-bit Windows binary of the sgminer 5.4.0 fork for Siamining with Stratum support (source). Do note that this miner will currently only work with the Stratum Mining Protocol for Sia implemented by Siamining. The miner works on both AMD and Nvidia GPUs, so you should be covered regardless of the GPUs you have available, though it uses OpenCL for both. Our initial tests are showing really good results in terms of efficiency and lack of stale shares, so it seems that things are already working pretty well with this Stratum implementation for Siacoin (SC) pool mining at Siamining. As a result now you have even more alternatives for pool mining Siacoin to try and choose from…

Updated ccMiner 1.8 fork by tpruvot With LBRY Support

20, Jul 2016

ccminer-1-8-tpruvot-lbry

While LBRY is still in Beta and you need to request an invitation in order to be able to get early access to the platform (currently only available for Mac OSX and Linux), people have been mining the LBRY Credits (LBC) for a while now on AMD via the dedicated sgminer fork or on CPU, but today tpruvot has updated his ccMiner fork (source) with the final 1.8 release that adds support for LBRY Credits mining on Nvidia GPUs as well.

We have compiled a Windows binary of the latest ccMiner 1.8 source code from github and you can download and try it for mining LBC from the link below. It is a 32-bit Windows binary compiled with VS2013 using CUDA 7.5 for Compute 2.0 to Compute 5.2 Nvidia GPUs, though it also works on Nvidia Pascal GPUs. We are going to be testing the miner with different CUDA versions to see if there is a better working combination and if we find such we are going to update the binary. If you are in a hurry to get to mining LBRY Credits however you should be all set to start with this release and enjoy the good performance that Nvidia GPUs provide for this algorithm. Below is a quick benchmark with a few Nvidia GPUs using this Windows binary as an idea to what you can expect in terms of hashrate for mining LBRY Credits.

Mining hashrate for LBRY Credits:
– GTX 970 – 127 MHS
– GTX 980 Ti – 156 MHS
– GTX 1070 – 242 MHS
– GTX 1080 – 313 MHS
