ccminer-1-5-75-git-spmod

A new update in the form of a Windows binary compiled from the latest Git source code of the ccMiner 1.5.75-git SP-MOD fork by SP optimized for the latest Maxwell-based video cards (source). The new release 75 marks a significant change as the project is now migrated to CUDA 7.5 and is compiled with it as a result the initial release may have slower hashrates for some algorithms than the last CUDA 6.5 release 74. Quark and Lyra2v2 should initially have pretty much the same hashrate while Qubit, X11 and X13 for example should be slightly slower. The most notable decrease in performance is with NeoScrypt, so if you are mining NeoScrypt crypto coins you should not be in a hurry to switch to the 75 release, though we are most likely soon going to see it catching up, so do not forget to support SP with a donation. 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 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.

Recently we have picked up the last 20 releases of the ccMiner SPMOD fork for Maxwell and tested them on a Gigabyte GTX 970 WF3 GPU. running at stock frequencies to see what has happened with the hashrate in the X11, Quark, NeoScrypt and LyraREv2 algorithms. There were users that wanted us to repeat the same test with a GTX 750 Ti GPU, so we have picked up an eVGA GeForce GTX 750 Ti video card and repeated the same tests. The first version we tested with ccMiner 1.5.53-git SP is from early July and looking at the results it seems that the most notable improvement is with Quark as well as some slight improvement with X11. Lyra2REv2 support has been added in release ccMiner 1.5.60-git SP, so there are no results prior to that, it seems however that the initial versions and the last one have pretty much the same hashrate with some drop with some in-between versions. The NeoScrypt hashrate hasn’t changed much, there is some slight variance with different versions probably due to the Boost frequency of the GPU variating a bit. Do note that these are results with publicly available and open source code, there could be some higher performance private miners also available and you might be able to squeeze more performance with different intensity settings (other than the default ones) as well as by overclocking the video card.

Since we’ve been closely following the development of the different ccMiner forks and have been compiling Windows binaries for most of the updated versions we have decided to do an interesting test. We have picked up the last 20 releases of the ccMiner SPMOD fork for Maxwell and tested them on a Gigabyte GTX 970 WF3 GPU running at stock frequencies to see what has happened with the hashrate in the X11, Quark, NeoScrypt and LyraREv2 algorithms.
