Hi all. I have a problem with a multi-graphic-card setup. I have an asus maximum V extreme MB with two sapphire hd7950. If I try to plug in only one card I can get it to run at decent speeds (580Kh/s) without much effort. I'm testing litecoin of course.
When I try to plug in the second card, I get a lower global hashrate ~530Kh/s! Why is this happening? Is there something that I should pay attention to when using a multicard setup?
Thanks
