New update in the form of a Windows binary compiled from the latest Git source code of the ccMiner 1.5.78-git SP-MOD fork by SP optimized for the latest Maxwell-based video cards (source). The latest release adds support for the new Blake256 algorithm that Vanillacoin (VNL) has just forked to from WhirlpoolX. Do note that the Blake256 algorithm used by Vanillacoin is slightly different from the one used by BlakeCoin, so you need to use the one specifically for Vanillacoin! 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.

New ccMiner Fork from DJM34 With Faster NeoScrypt
24, Jan 2016
After a crowdfunding effort to accumulate 2.5 BTC from users DJM34 has released a faster open source NeoScrypt kernel (source). Apart from the NeoScrypt the rest is based on the latest ccMiner form from SP version 1.5.78 that uses CUDA 7.5, so it is pretty much useful only if you are mining NeoScrypt-based altcoin. We have compiled a Windows 32-bit binary of the new ccminer djm34 neoscrypt fork with faster NeoScrypt using VS2013 and CUDA 7.5 as well as CUDA 6.5 (two versions available), compatible only with Nvidia Maxwell GPUs (Compute 5.0 and 5.2). Below we have compared the Neoscrypt performance using GTX 970 of this new release with the ccMiner 1.5.74 from SP with CUDA 6.5 and ccMiner 1.5.78 from sp with CUDA 7.5 to see what is the performance gain. Note that the initial ccMiner releases from SP with CUDA 7.5 had brought a significant drop in performance in the NeoScrypt algorithm, so it was best to use 1.5.74 with CUDA 6.5 for NeoScrypt.
NeoScrypt GTX 970 hashrate performance:
– ccMiner 1.5.74 CUDA 6.5 SPMOD fork: 525 KHS
– ccMiner 1.5.78 CUDA 7.5 SPMOD fork: 275 KHS
– ccMiner djm34 neoscrypt 6.5 from djm34: 632 KHS
– ccMiner djm34 neoscrypt 7.5 from djm34: 611 KHS
Note that the comparison with 1.5.78 is with an earlier release that did not include the latest NeoScrypt kernel from djm34, because it seems that SP has integrated it in the latest GitHub code after the code has been released by djm34.

The ccMiner SPMOD fork for Nvidia Maxwell GPUs (source) has recently been migrated to use the newer CUDA 7.5 from the older CUDA 6.5. The latest version with CUDA 6.5 support was version ccMiner 1.5.74 and the latest version is ccMiner 1.5.78 that already uses CUDA 7.5. The first release with CUDA 7.5 had not so good performance and was slower in some algorithms in terms of performance as compared to the latest CUDA 6.5 release, but the latest code has been optimized to offer similar or even better hashrate in most supported algorithms. We took an Nvidia GeForce GTX 970 (Gigabyte GV-N970WF3OC-4GD) running at stock frequencies for a spin with some of the currently popular algorithms to compare the performance of the latest CUDA 6.5 to the latest CUDA 7.5 release of ccMiner spmod. The results in the table clearly show that aside from NeoScrypt the latest CUDA 7.5 release offers very similar or even slightly better hashrate compared to the latest CUDA 6.5 version. The hashrate of X13, X15 and Qubit is still slightly slower, but not much. So unless you are mining NeoScrypt you should have no reasons not to upgrade to the newer CUDA 7.5 releases and soon we are probably going to see even better performance thanks to further optimizations of the code. Do note however that some other Maxwell GPUs might have some more variance in terms of performance difference between the two compared versions.
