Hello i'm from Portugal and like u all a proud owner of an p5w. Although i think it's a good board i'm havin' problems with my OC. here is my rig:

Q9450
Corsair 2GbX2 (1066Mhz)
HD3870X2
P5W DH Deluxe (bios 2704)
Asus Silent Knight II cooler

I've tried to set FSB to 385Mhz and the mem to 976Mhz, everything ran smooth, crysis ran better than ever but it always kept crashin' (BSOD). I don't know a lot about voltages but everytime i changed them i had too clear cmos.

Can someone help me?
