The latest GMiner version 1.31 brings an important update for everyone interested in Grin mining, namely support for Grin’s Cuckatoo31 algorithm to Windows miners as previously the C31 algo was only available with the official Grin miner for Linux and Mac OS X. Do note that Cuckatoo31 support (Grin31)requires 7.4 GB VRam, will work on 8GB cards under Linux and Windows 7, but will not work under Windows 10. Video cards such as GTX 1080 Ti do work under Windows 10 and should be able to provide about 0.6-0.7 G/s hashrate for C31. The latest update should now work fine with both C29 and C31 for Grin in NiceHash as well as there were some issues with the last few versions and NiceHash in the last days due to changes happening with the Grin support.
The GMiner Nvidia CUDA miner requires an Nvidia GPU with CUDA compute capability 5.0 or later as well as CUDA 9.0 driver support. Do note that GMiner is a closed source miner for Nvidia GPUs with binaries available for both Windows and Linux, also there is a 2% developer fee built-in the software.
