Try this if your rev. 1.04 won't hit 200 fsb.. worked for me

I had 1007 Bios and I heard 1004 was better for overclocking(don't ask me why) so I said what the heck and tried it. I could only hit 192 with 1007 but 200 so far with 1004! It is worth a try is you have tried everything else like I had...

Good Luck
