Alright I've got a small problem here.

I'm overclocking my q6600 and it runs prime small fft and 30mins of occt, when I run large fft then it will eventually bluescreen and reboot dumping the physical memory.

I know this means there's something with the ram, but it's underclocked and at stock volts right now. Is there another setting to adjust? I have the GTL setting appropriate.
