My System Specs


I have gotten it stable past 4GHz, but don't run it much because of temps.
Go ahead and post that link though...

I took a look at the link, and his vdimm at 1.72 volts (post #13). I thought the max safe vdimm is 1.65v since i7 memory controller can only take 1.65 volts. Any comments?

The 1.65v thing was something raised with ES (engineering sample) chips. As far as I can tell (and have read) this issue was either solved or deemed unneeded on final silicon. Only that if you give it (massive) volts you could fry chips. This seems to be in/around >1.9-2.0v

Everyone keeps just pointing to the anandtech article where this was raised as their validation that its true. It was nearly 300 days ago the article was written and he said it, citing NDA that he couldnt say more. He never followed up on that statement.

Who knows? Maybe someone with better googling skills the myself can find the 'official' Intel press release. I cant seem to.

re-visiting this thread, no matter what ive set it 'eventually' fails and BIOS resets ... sometimes after months of stable running

best practice would seem to be getting the CPU clocked stable, THEN doin the RAM .. [id always set RAM to its 'rated' 1600mhz + 8-8-8-24 and followed with CPU]

tho this latest failure to boot was caused by the last udev version in sid, it didn't wait long enough for it's message passing socket to appear .. setting Optimised Defaults got me past it and allowed install of a fixed version [udev 169-1+c0.aptosid.1]

anyway, currently ive got vCore on Normal and im gonna work on from there
# Core i7 920 FBO/BATCH # 3836B177 C0
# GA-EX58-UD3R rev 1.0
# Bios :f12q
# OCZ3G1600LV6GK 3 x 2GB
# Video card:-BFG GT260
# Power supply:-Pc Power & Cooling 750w
# Operating System:-XP/Aptosid64
# CPU and System Cooling:-Noctua
# CPU and System temps:-43c-70c
