Hey, thanks for the guide!
Although when I use your parameters with the latest miner () with my GTX970 it says:
"No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G argument" (my iGPU is deactivated in the BIOS)
when i substituate the -G parameter with the -U or add after -G "--opencl-platform 1" I get it running but not over 14MH/s... Can you help me?
I use ethminer 0.12.0 (https://github.com/ethereum/webthree-umbrella/issues/342)
