I feel so dumb...I forgot to change the RAM timings back to default.
Oi, that caused me a lot of frustration. Well, I got it running @ 3.6GHz, 9x Multiplier, 1600MHz FSB, 1.475V, DDR2 800. Ran a stress test for 5 mins, no problems except the temperature: 58C. Looks like its time to pick up that nice watercooling kit...
Neeways, thanks for all the help.
