The latest two versions of GMiner 1.37 and 1.38 have increased the supported range of GPUs over what the miner was capable of running on regarding Grin, Swap and Aeternity mining as well as some additional algorithms now also supported on AMD GPUs. GMiner 1.37 added Equihash 144,5 and 192,7 solver support for AMD miners on top of the already existing Cuckaroo29, Cuckoo29, Cuckaroo29s and Equihash 150,5 as well as some minor performance improvements for beam on AMD cards. A 5GB solver for Grin29 / Swap / Aeternity was added as well that allows the mining on 6GB cards under Windows 10 and in the latest release that was further improved by adding 4GB solver for Grin29 and Swap that should work under Linux and Windows 7 on 4GB VRAM GPUs.
The GMiner miner requires an Nvidia GPU with CUDA compute capability 5.0 or later as well as CUDA 9.0 driver support, some algorithms are already supported on AMD GPUs as well (Cuckaroo29, Cuckoo29, Cuckaroo29s, Beam’s Equihash 150,5 as well as the recently added Equihash 144,5 and 192,7). Do note that GMiner is a closed source miner for Nvidia and AMD GPUs with binaries available for both Windows and Linux, also there is a 2% developer fee built-in the software.
