The miniZ Nvidia CUDA clodes source miner for Windows and Linux has been available for a while already, but what caught our attention recently is the addition of support for the Equihash 150,5 algorithm used by BEAM. The miner also supports Equihash 144,5 as well as 192,7 and 96,5 and the various crypto currencies that use these algorithms on compatible 2GB Nvidia GPUs and it there are CUDA 8.0 and CUDA 10.0 versions available including support for Nvidia RTX GPUS with the CUDA 10 release. Since it is a closed source miner there is also a developer fee of 2% percent included.
Back to BEAM support and the Equihash 150,5 algorithm, the miniZ miner took the lead in terms of performance with its recent release over other popular miners that already had support for the algorithm. You might want to check it out if you are mining BEAM or another crypto currency that uses the same algorithm, even NiceHash support is properly working and present, so that will work too. At the moment miniZ does seem to be a good alternative for Equihash 150,5 or BEAM mining to the popular GMiner software that is one of the most used solution for that particular algorithm on Nvidia GPUs.
