Ok any fsb over 451 does NOT post. I tried putting vcore to 1.49, bumping NB/SB, pci-e freq. to 105. I have DDR2 800 crucial ballistix and I know it can go beyond running at ~900 to about 1100 (I had my friends try the ram on their computers). Temps are not a problem because when I boot at 450, orthos load for 20 mins are avg of ~48. I thought maybe there is a strap Im hitting so I put the fsb to 500 but still no luck. If anyone wants screenshots or info let me know. Anyone with suggestions because Im getting really bummed out here.
 
Hm.. maybe you are hitting the cpu FSB wall? so 451 = POST and 452 = No Post? Then definitely CPU fsb wall.. had that once with my pentium E2140.

I actually have E6550 and running at 475 FSB... 451 seems pretty low for 1333FSB cpu
 
I thought I hit a wall btwn 440 and 450 on my e6750 when I first started overclocking. It wouldn't even try to post or power up or anything btwn 440 and 450. Went up to 455 and it worked great. I then creeped it up to 468 successfully, but it wouldn't post over 468. Try going up to 455, then 460, then 465, etc. Bump vcore to 1.52, it will still be below 1.5 after vdroop. Also, what are mch, vtt, ichio at?
