Core i7 920 rev D0 stepping 5 :)

Does anyone knows if BCLK is CPU dependent or the motherboard? I mean, what is the factor to run at high BCLK.

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)

Same here, tried everything... can't get past 200Mhz on my R2E & i7 920 D0??

However, 21x200 is rock solid 24/7.

I suppose when you mean "everything," that includes bumping up PCI-E Frequency to 110+, too?

I did try 101, 103, 105 & 110. Also eliminated RAM by lowering multi etc.

Strange how I can't post 1MHz above 200 BCLK??

A mystery we all have to discover, I guess. The i7 is still very much fill with mystery. Same board and model of CPU, same settings, etc...some users are able to do things others can't.

Am I missing something? What has PCI-E frequency got to do with high BCLK clocks? I mean if we stress the PCI-E frequency, it'll affect the graphics card and prolong usage at such high freq. might kill it?

Well, i7 is still new to most of us so maybe this PCI-E freq. has some secret beneath it?

By raising the PCI-E frequency you raise the BCLK limit. Don't ask me why

You can boot from bios into windows @ 230 bclk? That is impressive if so. I am unable to boot higher than 222 on my Classified but can go much higher once already into Windows. Is this on the LP UT? might have to pick one up to play with!
