Here comes a new ccMiner 1.7.6-r5 fork from Nanashi Meiyo-Meijin (source) based on tpruvot’s fork of ccMiner, but with even faster Lyra2REv2 performance. The ccMiner 1.5.80-git SP Nicehash fork from yesterday with improved Lyra2REv2 hashrate was apparently based on the code from the same author, but the Windows binary we have compiled from the ccMiner 1.7.6-r5 source seems to be slightly more optimized and thus is a bit faster. Below is a comparison between the two released on different Nvidia Maxwell GPUs to give you an idea on what is the difference in performance.
ccMiner 1.5.80-git SP Nicehash:
– Nvidia GeForce GTX 950 – 9.88 MHS
– Nvidia GeForce GTX 970 – 20.98 MHS
– Nvidia GeForce GTX 980 Ti – 30.11 MHS
ccMiner 1.7.6-r5 Nanashi Meiyo-Meijin:
– Nvidia GeForce GTX 950 – 10.21 MHS
– Nvidia GeForce GTX 970 – 21.49 MHS
– Nvidia GeForce GTX 980 Ti – 31.38 MHS
Apparently the optimizations for the Lyra2REv2 performance were made for mining Monacoin (MONA), buy you can mine any other altcoin that uses the same algorithm. So here comes the 32-bit Windows binary of the ccMiner 1.7.6-r5 fork from Nanashi Meiyo-Meijin is compiled with VS2013 and CUDA 7.5 with a wider range of Nvidia GPUs supported – from Compute 2.0 all the way up to Compute 5.2 (we have only tested it with Maxwell GPUs though). There is no point in publishing a 64-bit binary as our tests have shown that it provides lower performance when compared to the 32-bit version that is available here. You can follow the development of this fork on the official dev thread, though it is in Japanese and you may need to use an online translation service.
Nicehash has forked SP’s ccMiner 1.5.80 GPU miner for Nvidia MAxwell GPUs (source) and has added significantly improved support for the Lyra2REv2 algorithm that can apparently provide up to 100% increase in terms of performance. SO if you are mining a crypto currency that uses the Lyra2REv2 algorithm or are selling your hashrate on Nicehash, then you might want to go for the new miner. We have compiled a 32-bit Windows binary, using VS2013 with CUDA 7.5 that you can download and try. Do note that it is compiled only for Nvidia Maxwell GPUs supporting Compute 5.0 and Compute 5.2 such as GTX 750, 750 Ti, GTX 950 GTX 960, GTX 970, GTX 980, GTX 980 Ti and GTX Titan X.
A quick update of the public ccMiner fork by SP of his Nvidia Maxwell optimized miner in the form of a Windows binary compiled from the latest Git source code of the ccMiner 1.5.80-git SP-MOD fork (source). The latest release comes with some fixes fox x17, x17 and Neoscrypt algorithms and some small speed improvements in various algorithms. Have in mind that is a CUDA 7.5 compiled release, the latest CUDA 6.5 release of SP’s fork of ccMiner was version 74. Do note that the SP-MOD fork of ccMiner is designed for Nvidia Maxwell GPUs such as the already available GTX 750, 750 Ti as well as the newer GTX 960, GTX 970, GTX 980 and GTX 980 Ti and GTX Titan X. The Windows binary release we have made available here is 32-bit with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based Nvidia video cards compiled with CUDA 7.5 and VS2013.
