Quick question to anyone with a crossfire setup on this board, similar setup to mine. I can run 3.6GHZ prime blend stable with single card, but when i put the other card in, my NB temps rise and 3.2ghz is all prime blend wants to be stable at. I know NB temp raise is from crossfire, but temps are fine, i have 4 120mm fans on the side of my HAF 932, also the NB is cooled by a Thermaltake Spirit II cooler, any ideas??? thanks.
