So I am having trouble getting two GPUs running in windows. I am wondering if there is a secret!
I have a 6870 that is installed and running with poclbm with guiminer. I also have a 4870 card in the board's second x16 slot. The device manager see the card and correctly identifies it. However, when I run poclbm in command line mode I only see [0-0] Barts as well as the CPU. I have also noticed that there is no mention of the 4870 card in CCC. I believe that I'm missing something basic since this is my first attempt at multiple GPUs on a mobo.
