    I'm running the Q9550 and I set my FSB speed to 400 and turned off the 0.5x multiplier value so that it is 8.0 instead of 8.5. That means, 400 x 8.0 = 3,200mhz, with no voltage increases on the Gigabyte GA-EP45-UD3R Rev 1.1 and I'm doing it on stock cooling with almost no increase in temps from stock. This keeps my DDR2-800 RAM running at 1:1 with the CPU and everything is just fine. I didn't even try to go any higher....so not sure on potential.

    I run at about 34 celcius at idle and get around 60 at full load.

    You might want to give this a read: HOWTO: Overclock C2Q (Quads) and C2D (Duals) - A Guide v1.1 - Overclockers Forums

    All the PX5 series boards are really good overclockers... very stable too. Pretty much all you have to do these days is set your RAM timings and let her rip. :) Don't worry about your RAM blowing up at 1066MHz, just make sure you have the correct voltage and all will be good.
