New ccMiner fork by Djm34 with NeoScrypt and Yescrypt Support

2, May 2015

ccminer-djm-edition-yescrypt

We have compiled a Windows binary for the new ccMiner fork by djm34 (source) that now has support for NeoScrypt and Yescrypt GPU mining on Nvidia-based video. Our Windows binary is compiled with VS2013 and CUDA 6.5 and supports Compute 3.5, 5.0 and 5.2 GPUs, you can download and try it from the link below, there is an example BAT file setup for testing hashrate for the two new algorithms. We are getting more than 1100 Hashes per second on GeForce GTX 980, so better than the performance from a Radeon 280X with the sgminer fork. On a GeForce GTX 750 Ti we are getting very good performance as well with close to 600 Hashes per second or slightly less than on Radeon 280X. Do note that there is still more to be desired from the GPU miner as it is not faster than mining Yescrypt with an up to date CPU, for example a single Intel Core i7 5820K CPU achieves around 5.1 KHS mining GlobalBoost-Y (BSTY).

New sgminer 5.1.0 fork with Yescrypt Support Available

2, May 2015

sgminer-5-1-0-yescrypt

You can now mine GlobalBoost-Y (BSTY) with AMD-based video cards thanks to a new fork of sgminer 5.1.0 from djm34 that adds support for Yescrypt (source) and we have compiled a windows binary that will allow you to try it out. The windows binary is compiled for x86, so it should work on wider range of systems using 32-bit or 64-bit Windows. Do note that Yescrypt GPU mining is still in early stage, so it might be a bit buggy initially and further optimizations in performance should be possible as this is a preliminary work to port the algorithm to GPU support. The coin does seem to handle well high intensity, so you should start low with 9 for example, also lower worker size such as 16 and 512 threads could be a good start. We are seeing a performance of about 700 hashes per second on a non-overclocked AMD Radeon R9 280X GPU with the settings above, but you are welcome to experiment. Do note that there is still more to be desired from the GPU miner as it is not faster than mining Yescrypt with an up to date CPU, for example a single Intel Core i7 5820K CPU achieves around 5.1 KHS mining GlobalBoost-Y (BSTY).

Update: There is now a slightly faster yescrypt kernel available that allows you to get some extra speed, we got to almost 800 Hashes per second with it, you can download the updated version from the link below. Also the latest version includes yescrypt-multi algorithm for Nvidia Maxwell GPUs (Compute 5.0 or newer) that may provide faster performance than the ccMiner release according to the author, though in our case ccMiner was still faster.

Updated Windows Binary of the ccMiner 1.5.48-git Fork by SP for Maxwell

1, May 2015

ccminer-1-5-48-git-spmod

New update in the form of a new Windows binary compiled from the latest source code of ccMiner 1.5.48-git SP-MOD fork of the Nvidia GPU miner optimized for the latest Maxwell-based video cards by SP (source). This version includes additional improvements and fixes such as a fix the extranonce bug at Yaamp and slight performance increase in Qubit performance. 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 and GTX 980. The Windows binary release we have made available here is compiled with support for Compute 5.0 and Compute 5.2 GPUs or with other words only for Maxwell-based cards with CUDA 6.5 and VS2013.
