ccminer-1-6-3-git-tpruvot

We have compiled an up to date Windows binary from the latest ccMiner 1.6.3-git by tpruvot (source). The latest version adds support for the NeoScrypt algorithm based on djm34’s work who recently added NeoScrypt support to his fork with minimum requirement for Compute 3.5 capabilities from your Nvidia GPU. With this version of ccMiner we are getting around 146 KHS hashrate mining NeoScrypt on a GeForce GTX 750 Ti GPU which is about the same performance we are getting on the same hardware using djm34’s fork which is to be expected. Our windows binary is compiled with VS2013 and supports Compute 3.5, 5.0 and 5.2 GPUs, you can download and try it below, there is an example BAT file setup for testing.

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).

sgminer-5-dev-workaround-fix

When the new sgminer 5 develop version was updated to include the latest Neoscrypt OpenCL kernel from Wolf9466 a few days ago it has turned out that the latest performance optimizations do break compatibility with Nvidia cards as well as with the latest AMD video drivers. The solution was to use older AMD Radeon drivers to generate the kernel binary and them get back to the latest, but now there is an even easier workaround that was discovered by an user called insanid from the Feathercoin forum that does not require you to instal different drivers. All you have to do is to include the OpenCL libraries from an older driver such as 14.6 or 14.7 in the folder of the sgminer and the miner will generate properly the kernel binary file. Then you can either run sgminer for Neoscrypt with these DLL files in the folder or remove them and use the ones installed by the latest video drivers such as 14.9. To make it easier for you we have included the OpenCL DLL libraries in our windows binary compilation of the latest sgminer 5 development branch (source) and you can download the full package from the link below and try this workaround yourself.
