... take your over clock setting off auto that is your problem, you using cpu level up i know you are lol. i have the same bios as you, take it off auto set it to manual run a fsb of 400 and u will be at 3.6 ghz and stable, im assuming u dotn have stock cooling, and you should be able to bump your ram pseed up by intervals of 200. when u have the cpu level up option being used you cant oc yoru ram and itl set it at a default speed which it finds aprooving, when on manual and setting you can even set your timings to manual.
