ccminer-1-7-2-tpruvot

Version 1.7.2 of tpruvot’s ccMiner fork source) for GPU mining on Nvidia-based video cards has been released and it comes with official support for Vanillacoin (VNL) as well as Decred (DCR) support. Below you can find compiled Windows binaries to try out the mining them, both are Blake256-based, but with some different requirements such as the need to use longpoll and getwork, and no support for stratum for Decred for example. There are two versions available, the 32-bit one is with support for older Compute 2.1 and 3.0 GPUs while the 64-bit version is for the newer Compute 3.5, 5 and 5.2 cards. We have tested the new release on GTX 970 and the results are slightly better at about 1.35 GHS (with the 64-bit miner) than what we are getting with the cgminer fork for Decred that relies on OpenCL that is also compatible with Nvidia cards. The ccMiner fork might be helpful to people that are having very high CPU usage with cgminer that results in lower mining performance, though the CPU load is still not that low even with ccMiner. Also the use of ccMiner for mining Decred could result in less rejected shares from the pool and no weird errors as some people are experiencing with cgminer, so if you are mining DCR on Nvidia with cgminer, then you should try with ccMiner as well.

ccminer-sp-vanillacoin

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.

ccminer-djm34-neoscrypt

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.
