UD7 - Primes fine but won't cold-start

fritzman · Jul 12, 2010

Hi team.

I have now tried two 930 cpu's in this UD7 board. It's on F7P BIOS and on No.1 930, booted into windows at 4.4 with 1.344 vcore actual.

I have taken a slower approach with this 2nd chip, and let it prime last night for 17hrs at 4.0 (20x200) with 1.280 actual vcore. I'm running an H50 cooler now so temps never venture above 73degrees.

Here are my BIOS shots, hoping they might help, but the guts of the issue is... every time I turn the computer off, it goes into an endless lopping of start, on for about 3 seconds - restart, and keeps repeating that endlessly.

I can overcome it by turning off the power. Then it will boot fine, I go into BIOS and (actually, I'm not sure whether I even need to so should check) reload my saved 20x200 BIOS, hit F10 and she's away.

It's gotta be something that someone has worked on and solved before, so hopefully someone will have the solving of it.

TIA.

Have upped the qpi/vtt to 1.315 and that seems to have it sorted.

Passed LinX at 205x20 @ 1.312 actual with the ram @ 820/8-8-8-24 max 80 degrees...
