Updated Windows Binary of the ccMiner 1.5.38-git Fork by SP for Maxwell

12, Feb 2015

ccminer-1-5-38-git-spmod

Here comes a new windows binary compiled from the latest code of the ccMiner 1.5.38-git SP-MOD fork of the Nvidia GPU miner optimized for Maxwell GPUs by SP (source). This version has a more fixes and a few performance improvements in the different supported algorithms since the last binary we have compiled a few days ago. So if you are mining with Nvidia Maxwell GPUs you might want to update. The SP-MOD fork is designed for running on Nvidia Maxwell GPUs such as the already available GTX 750, 750 Ti as well as the newer GTX 960, GTX 970 and GTX 980. The windows binary release we have made available here is compiled with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based cards with CUDA 6.5 and VS2013.

Performance Results from the ccMiner fork With NeoScrypt Support

1, Feb 2015

ccminer-neoscrypt-fork

Last month we’ve written about the Crowdfunding Campaign for ccMiner fork With NeoScrypt Support and the miner is already being made available for people that have donated to the developer djm34. We have already played a bit with the latest version of the ccMiner fork with NeoScrypt algorithm support and have tested it on multiple Nvidia-based video cards. Although we have tested the miner on Maxwell-based GPUs (Compute 5.x) only the size of the compiled Windows binary suggests that the miner is also compiled for Compute 3.x cards, so it should work on older video cards as well, though the performance may not be that good. Do note that the ccMiner fork with NeoScrypt support apparently does not currently have support for extranonce that is being used by services such as NiceHash.

We have used GTX 980, GTX 960 and GTX 750 Ti for our tests and the results you can find below are achieved with the latest video drivers that were released along with the GeForce GTX 960 video cards. We are seeing a considerable increase in performance when we compare it to the initial performance results that were shared by djm34 when he initially announced the crowdfunding of the project early last month. So the development of the miner hasn’t stopped and you can show your support by donating to the project to keep the developer motivated and to reach the goal of making it public for everyone.

ccMiner NeoScrypt performance:
GTX 980 – 554 KHS
GTX 960 – 304 KHS
GTX 750 Ti – 149 KHS

There are some important notes regarding the parameter throughput that is used by the miner, it seems that for us value of 1 works best for GTX 980 and GTX 960 bringing a more consistent and high performance. The performance of the GTX 980 is not affected much by the throughput option, so it works without it pretty well, but the GTX without the extra option provides just about 50-60 KHS. For GTX 750 Ti there seems to be not much of a difference what setting we use or throughput in regards to the hashrate we are getting, although a value of 1 does seem to also provide a more consistent hashrate, but your results may vary. Do note that the results posted above are from a reference GTX 750 Ti and GTX 980 video cards that are running at their stock frequencies while the GTX 960 GPU is a factory overclocked ASUS Strix GTX 960. This clarification is important when you take into account the hashrate that the GTX 960 has as compared to the GTX 750 Ti – double, and more that 50% that of the GTX 980 card.
