There is a new official release of tpruvot’s ccMiner fork version 2.2.3 available (source) with new algorithms supported and additional improvements. The latest version brings support for Polytimos algorithm as well as support for the KeccakC algorithm, along with an optimized Keccak support for SM5+ GPUs, based on alexis78 improvements. The official Windows binaries for the new version are compiled for SM 3 Nvidia GPUs and CUDA 9 only (require driver version 384.xx or newer) and are available in 32-bit as well as 64-bit version.

After a quick test of the KeccakC support we can suggest that you might want to try increasing the intensity over the default value for your GPU for some improvements in terms of performance, though even then there is still a faster fork of ccMiner with KeccakC support. If you are interested in mining CreativeCoin (CREA) that uses the KeccakC algorithm with best performance you might want to check out this ccMiner fork for optimal performance.

The development of some of the ccMiner forks for Nvidia GPU miners didn’t seem very active visually in the last couple of months, especially with coins such as ZCash (ZEC) that came with their own miner releases, but it hasn’t been stopped. A few days ago tpruvot has made a pre-release version of his new ccMiner 2.0 available (source) for people interested in checking it out with probably a few small things left to be ironed out before the final 2.0 release is made available. So if you are using Nvidia GPUs to mine crypto coins then you might want to give it a try and don’t forget to send a tip to your local friendly ccMiner developer for a beer or two to show your support.

ccMiner 2.0 RC2 changelog:
– Handle cryptonight, wildkeccak and cryptonight-lite
– Add a series of new algorithms: timetravel, bastion, hmq1725, sha256t
– Import lyra2z from djm34 work…
– Rework the common skein512 (used in most algos except skein ;)
– Upgrade whirlpool algo with alexis version (2x faster)
– Store the share diff of second nonce(s) in most algos
– Hardware monitoring thread to get more accurate power readings
– Small changes for the quiet mode & max-log-rate to reduce logs noise
– Blake2s fix, variant built with CUDA 6.5 (not usable for lbry)

Do note that this release may not contain the best optimizations and fastest performance on all of the supported algorithms, so depending on what you are currently mining you may need to stick to another faster fork of ccMiner or not. Also the CUDA 6.5 binary release does not work for LBRY mining as noted in the changelog, so either use the 8.0 release or compile with 7.5 for mining that coin.

Alexis Provos has updated his fork of ccMiner (source) with improved performance for mining Vcash and Decred Blake256-based crypto coins and we have compiled a Windows binary to try it out. His latest release brings the same performance or even a slightly higher for Vcash (former Vanillacoin) as the specially optimized CUDA 6.5 Compute 3.5 release of ccMiner using the latest CUDA 7.5 and the Compute version supported by the specific GPU you have. The Decred (DCR) hashrate is also higher when compared to the latest tpruvot release that includes the optimizations submitted by pallas. Below you can find a quick comparison of the hashrate you can expect from this release on GTX 980 Ti, the archive below includes a 32-bit and 64-bit binaries compiled with CUDA 7.5 and VS2013 for Compute 2.0 – Compute 5.2 GPUs, though we have not tested how it handles on older GPUs.

Do note that the focus of the ccMiner fork from Alexis Provos is on the Blake256 algorithms and most specifically on Vcash and his release brings support for very few algorithms. There are some optimizations available for the other supported algorithms as well, so you might want to compare them as well in terms of performance. It is not a full ccMiner fork with support for all of the algorithms available in other releases, so with this one you can mine only the following algorithms:

– blake for Blake256-14rounds (SFR)
– decred for Blake256-14rounds (DCR)
– blakecoin for Blake256-8rounds (BLC)
– vcash for Blake256-8rounds (XVC)
– whirlpoolx for WhirlpoolX (old VNL algo)
– keccak for keccak256 (Maxcoin)
– lyra2 for LyraBar
– lyra2v2 for VertCoin

Since this fork is not based on the latest code by tpruvot there might be some bugs that have been resolved in the newer codebase of tpruvot’s ccMiner. We have observed something strange already, namely the very fast increase of the difficulty to a very high level on the Suprnova pool for Decred using Stratum over getwork, though it works just fine on YIIMP. In the end the difficulty issue appeared to be temporary and apparently something poolside and not related to the miner itself. Below you can find some performance comparison results using an Nvidia GTX 980 Ti GPU:

This release with GTX 980 Ti intensity 31 Decred, 30 Vcash
Vcash – 4453 MHS
Decred – 2394 MHS

1.7.4 alexis78 release Compute 3.5 CUDA 6.5
Vcash – 4418 MHS

Latest 1.7.6-git tpruvot with Pallas tweaks
Decred – 2218 MHS
