I've installed on AMD rig few Nvidia cards, all is fine but i can't control clocks/voltages via Afterburner/Trixxx on AMD cards, Nvidia clocks/voltages/fan control works. Already tried reinstall amd drivers. Win7 x64. Maybe someone have similar setup. Next step - i will try control via miner.
Same story here - just use afterburner for NVIDIA and Claymore for AMD
Another problem - can't catch temps on amd chips. Tried GPU-Z, AB, Trixxx etc.
