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).

Claymore has updated his dual Ethereum plus DCR, SC, LBRY, PASC, Blake2s and Keccak AMD and Nvidia GPU miner to version 11.6 bringing some performance improvements for slower Nvidia GPUS as well as increasing the usability of older GPUs with less VRAM along with new features and bug fixes. You can read what is the full list of changes in the latest version 11.6 below:

– improved hashrate for weak Nvidia cards by about 1%.
– zero devfee for 3GB cards in Windows 10, same as for all 2GB cards.
– applied some tricks to increase available memory for 3GB cards in Windows 10 so you can mine ETH a bit longer.
– now you can press “y” key to turn on “Compute Mode” in AMD drivers for all cards (Windows only).
– Linux version: removed openssl library dependency.
– improved “-logfile” option, now you can use it to specify a folder for log files, use slash at the end to do it, for example, “-logfile logs\”.
– added “-epoolsfile” and “-dpoolsfile” options.
– remote management: now “miner_getstat2” command also returns PCI bus index for every GPU.
– a few minor bug fixes and improvements.

If you are looking for a miner for Ravencoin (RVN) and its X16r algorithm or Pigeoncoin (PGN) and its X16S algorithm for AMD GPUs, then you might want to check out this new sgminer fork by brianmct (source). There are pre-compiled binaries available for both Windows and Linux, so you should be covered for the two operating systems, if using Linux make sure you have the required dependencies installed. Unfortunately this may not be the best performing X16r and X16S hashrate wise as our initial tests show, but at least it works and you have a working miner for X16S for AMD until a faster solution that works becomes available. There are more forks of sgminer that are trying to implement X16S support, but apparently there are some trouble making them work. A faster performing X16r AMD GPU miner that we have already posted about is available here, but it does not have support for X16S.
