Added a 3870 to go with my 3870 x2 today, even went and got vista ultimate 64 to have the crossfore X support in cat 8.3.

CCC says crossfire is enabled, gpu-z says it's disabled.

Running everything at stock speeds 3D 06 score is the same as it was before I added the 2nd card, while 3D 03 is 11K higher than previos stock runs.

My bigest problem is before I was using atitool and amd gpu tool for overclocking and it worked pretty well. But this method wont work for x2 and single gpu card. At least I can't get it to work.

Rivatuner only allows me to adjust the fan speed on 1 card.

So basicly I ned to know how to get the clocks up and fan speed up on both cards.

Also will it matter which card is in which slot?
