Core i7 920 rev D0 stepping 5 :)

[aoch88]

Bit of both cpu and board.. i have 4x i7 920 (2x c0 and 2x d0) and w3520 d0 all 5 cpus do 230bclk 32m pi and 3d bench on DFI UT X58-T3EH8 on air and water. I'm probably more board limited than cpu but each cpu required differing cpu vtt, ioh/ich voltages to reach 230bclk straight boot from bios into windows.

Thanks and darn, you've got plenty of i7 CPU's there, lol. Btw, I've got this weird problem whereby I could run Prime stable on 20x200 and 21x197 but the moment I do 21x200, nothing seems to work even if I add 2-3 notches of Vcore, PLL, VTT.

What do you think could be wrong? I tried 21x201 and no luck as well. What voltage do I normally have to add for higher BCLK (above 200)
