All About BTC, LTC, ETH mining as well as other alternative crypto currencies
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.
