Hello, I am having a problem enabling Crossfire with two Sapphire 5770 cards.

In CCC one of them always shows as "Primary Adapter" and the other as "Disabled Adapter". There is no option for Crossfire.

I have tried:
-Flashing the BIOS of the older card. One is a second generation Sapphire HD 5770, the other is the newest (third). I just purchased the newer one.

-The latest revisions of the 10.x and 11.x drivers

-Switching the cards' PCI slots

-Plugging my monitors into either card.

My system is:
Core i5 2500k
8gb
p8p67 rev 3.0
Fresh Windows 7 install


Thank you for your help
