Hi, yes it works fine with either one card individually and cod4 is the only game installed on this pc. I have managed to reset to defaults but i am new to this so can you please explain to me how i can underclock my cards, thanks.
Try setting the clock speeds of GP1 to match those of GPU2.
Thanks a lot iv tried asking all over the place about this problem and so far so good with matching the clocks, i really appreciate your help. Can i just ask what resolution could i go upto with these cards and is it possible to test if sli is working correctly?
