They're Micron D9's. Only thing that puzzles me is, why can't I run all 4 gb's @ say 800mhz memory, relaxed timings and still OC the CPU itself to 3.X-4.Xghz ?

I tried Raising the NB Voltage to 1.5v and wow...it went up to 43c and hard locked in BIOS after the unsucessful boot into Windows of a BSOD.
