New Fixed Windows Binary of the ccMiner 1.5-git Fork by SP for Maxwell

ccminer-1-5-git-spmod-new-fixed

Yesterday we have published a windows binary compiled from the latest code of the ccMiner 1.5-git SP-MOD fork of the Nvidia miner optimized for Maxwell GPUs by SP (source). However it had some issues present, like problem with the launch configurations for X15 on GTX 970/980 GPUs, but these were quickly addressed and are now fixed,s o we have updated our windows binary release. Since we also used the same fork of ccMiner in our Miner Control 1.5.5 Pack for Nvidia GeForce GTX 750 Ti also released yesterday, we have also included the new fixed windows binary in that package. So if you have downloaded it today you should re-download it again as the latest source code includes some other fixes and improvements as well. In terms of performance improvements, you will probably not see such as compared to yesterday’s windows binary, but if you are using an older release you should notice significant performance increase.

New Windows Binary of the ccMiner 1.5-git Fork by SP for Maxwell

ccminer-1-5-git-sp-mod-new

Time for another windows binary release based on the latest code of the ccMiner 1.5-git SP-MOD fork of the Nvidia miner optimized for Maxwell GPUs by SP (source). Since the last windows binary we have published a few days ago there have been a lot of fixes and improvements made to the code and we were pleasantly surprised today to see a significant performance improvement. The results we are getting in terms of hashrate on our stock test GTX 980 GPU for X11 have gone up from about 7900 KHS with the previous release to over 8300 KHS and for X13 up from a bit over 6200 KHS to about 6700 KHS. There are also hashrate optimizations for other algorithms – NIST5 is up to about 26500 KHS, so performance should increase not only for X-based coins, so definitely a recommended update for owners of Maxwell-based Nvidia GPUs such as GTX 750 series and GTX 970/980. There seems to be a bug with the launch config of X15 for Computer 5.2 cards as on GTX 750s it works fine, also the improvements are also present for GTX 750 and GTX 750 Ti users, but the hashrate increase is not so big. Do note that this fork of ccMiner is supports only Maxwell cards as it is optimized and compiled for Compute 5.0 and 5.2 architecture.

Nvidia GTX 980 Performance Improvements With The Latest ccMiner

24, Nov 2014

nvidia-geforce-gtx-980

Back in September with the release of the new Maxwell-based NVidia GPUs, the GTX 970 and GTX 980 we did some performance testing of the GeForce GTX 980 hashrate using the available at that time ccMiner and CudaMiner miners. Today, a bit over two months later we’ve decided to check how hings have progressed in terms of performance improvements of the various crypto mining algorithms with the latest optimizations available in ccMiner. We’ve used the just posted Maxwell-optimized ccMiner 1.5-git ccMiner fork from SP to get the performance results from the same GTX 980 GPU running at stock frequencies (overclocking can further increase performance).

There is no surprise that there are some significant performance improvements in various crypto algorithms that have been achieved using various optimizations, but to our surprise there ware a few algorithms that did perform worse. The results we got from Groestl, HEFTY1 and JHA were a bit lower with the latest ccMiner than what we got in terms of performance back in September. Some other algorithms also don’t seem to have very big performance improvements such as Keccak, Luffa512 or NIST5, but the more popular and still profitable to mine algorithms do come with nice improvements. You can thank for the increase in performance to all of the developers that continue to work actively and optimize the performance out of which SP and tpruvot seem to be the most active lately, djm34, tsiv as well as others who have contributed code and also Christian Buchner and Christian H. – the creators of the ccMiner in the first place. Their code contributions and efforts in releasing their work publicly deserve some appreciation from the miners who are using Nvidia GPUs in order to keep them motivated.
