All About BTC, LTC, ETH mining as well as other alternative crypto currencies
If you are using AMD Radeon-based video cards for mining crypto currencies you have probably noticed that some algorithms have issues with various video driver versions or the performance you get may differ between older and newer version. Since the AMD miners use OpenCL there is an easy solution that can help you deal with driver version issues and to get the optimum hashrate for a specific algorithm. There is not need to reinstall the complete video driver, you can just copy the OpenCL DLLs from the respective driver version inside the same folder where the software miner is (cgminer or sgminer) and when you run the miner it will load the different OpenCL version, regardless of what video driver you have installed. Do note that you need to delete the compiled kernel BIN file for the respective algorithm or algorithms when replacing the OpenCL DDL files in order to get the kernel recompiled with the different version. You can download the different AMD Radeon drivers OpenCL version 13.12, 14.4, 14.6 RC2, 14.8, 14.9 and 14.12 in a single package from the link below and try out what performance you will get by replacing the DLL files inside the miner software’s folder.
