Basically I'm trying to set my 6950 as a slave card, so that it can mine 24/7 and have my backup 8800 set to mine when I'm not playing games, but stop when I want to play a game and just continue to mine on my 6950. Is this possible? I keep getting no opencl devices found when I try to do this with guiminer.
Sorry but no
solid information here... But I have heard that in Windows 7 you can somehow install different drivers (amd and nvidia) for different cards. I'm pretty sure it can be done, maybe someone here knows. Or perhaps research into the Folding At Home community, I think that's where I heard it.
