Ok, feeling dumb here. I'm planning on getting the above-mentioned mobo, in combination with an i5-650, which is supposedly 3.2ghz. But when checking Asus's site for the RAM QVL, it has lists "for CPU at 2.3ghz, 2.6ghz, and 2.93ghz", and nothing further.
Is the 650 at 3.2ghz just flat out not compatible with the P7P55D? Or does speed over 2.93 just not change anything and anything on that list is OK?
