There is a new official release of tpruvot’s ccMiner fork version 2.2.5 available (source) that adds support for a few new mining algorithms, namely X12, X16r and X16S. The latest release also fixes issues on Neoscrypt and Equihash for the Nvidia Volta cards according to the developer. The two new X16 variants are getting a lot of attention lately – the X16r used by Ravencoin (RVN) and X16S used by Pigeoncoin (PGN). For people looking to mine X16r or X16S this may not be the fastest implementation out there, there are a lot of different ccminer forks and miners supporting that might provide better performance, so you might want to play around with these as well.

The latest official release version 2.2.5 from tpruvot is available as both 32-bit and 64-bit Windows binary releases for everyone using Windows and not keen on compiling the miner from source. The Windows binaries built with CUDA 9 for SM 3.0 or later Nvidia GPUs, so make sure you have up to date video drivers installed with support for CUDA 9.0 on your mining rigs.

Ocminer, the admin of the Suprnova mining pools, has been pretty actively maintaining and further improving his supminer fork of ccminer (source) adding numerous performance improvements for the X16r and X16S mining algorithms. So if you are mining either Ravencoin (RVN) that uses the X16r algorithm or Pigeoncoin (PGN) that uses the X16S algorithm you might want to try the supminer or update it if you already use an older version than the latest 1.5. In the last two days there were numerous performance updates regarding various algorithms that are a part of the X16r and X16S, so supminer could as well be the fastest miner for RVN and PGN at the moment. The miner is free and open-source with a 32-bit Windows binary release also available compiled for CUDA 9.1 (require R390 or newer Nvidia video drivers).

Another open-source fork of ccMiner called supminer (source) is now available, an optimized version from the operator of the Suprnova mining pools that promises up to 10% better performance than the recently released nevermore ccminer fork. The supminer ccMiner fork comes with with no developer fee, but you can show your support by mining Ravencoin (RVN) on Suprnova’s RVNCoin Pool. There is an official 32-bit Windows binary release available compiled with CUDA 9.1, so make sure you have up to date video drivers on your mining rigs. The code is compatible with Linux as well, though you will need to compile it yourself (make sure you have CUDA 9.1 installed to compile from source).

In theory the supminer should be faster than the other available ccminer forks with X16r support, but you should test and compare the different releases and see what works and performs best on your hardware. Feel free to report hashrates and stability on your mining rigs and how supminer compares to the nevermore and enemy miners. When comparing hashrates make sure you compare on the same algorithm, because hashrate varies depending on the currently switched to algorithm. Do note that the performance optimizations should not work only on the X16r algorithm, but should also help improve performance on other chained algorithms supported by ccminer.
