I have been having some difficulties with the P5Q Deluxe and over clocking it. I have ran programs like SP2004, Prime95, OCCT, and Memtest84+ and have not been able to find anything unstable. However even a small over clock on my q6600 G0 (2.8 was the lowest I was having instability at) the OS behaves strangely and games will freeze and require a hard reboot. Could I be having difficulties with Vista 64 and stability testing?
