I am having a very strange problem with my overclock, in windows the screen will freeze and my mouse and keyboard will not have power to them anymore and the only way to fix is a reboot. I have a q9650 so I decided to give it an OC. I had resisted the temptation to do so because I thought 3.0ghz quad core who could need more? So I changed the bus speed to 400, then upped the voltage on the vcore to 1.25000, I also upped the voltage on the FSB 0.05. I then changed the ram timings to auto for a 400FSB, this is where I think the problems lay. I dont know enough about latency timings to adjust them manually. Also I upped the voltage +0.2 volts on the ram and then it froze and then I tried +0.25 and it froze again so now I am back down at +0.2. I have disabled the speedstep features and the voltage regulation feature.
Additional info I ran Memtest 2.1.1 for 4-5 hours with 15-20 complete passes with no errors. Also I can run cpu intensive programs such as prime95 for hours with no freezing. This seems to happen randomly like sometimes 4-5 minutes in other times it doesnt happen for hours. Also there are no entries in the event viewer saying what happened before the freeze. This is a very strange problem and I really dont know what I can do to fix it so any help would be appreciated.
System:
intel q9650 @ 3.6 400x9 1.25vcore
Corsair x1333 ram timings autoset 10-10-10-26 1:2 ratio
voltage @ either +0.2 or +0.25
PSU: Zalman 750 watt w/heat pipes
Mobo: Gigabyte X48-DQ6 with F6D bios
Nvidia 9800 gx2 EVGA
