**OFFICIAL Gigabyte UD3 P45 Yorkfield (45nm Quads) OC and Discussion Thread**

[Jor3lBR]

I am now try the 10.5 multi with this QX9770. I am able to boot into windows and so far I have made it through about 30 minutes of Prime95 with 10.5 x 400MHz (4.2GHz) however, one thread quit right at the beginning and a second one quit after two minutes, the other two are still chugging away. Why is that? Not enough or too much of what?

vCore 1.44375v
MCH 1.6v
vDIMM 2.26v

GTL Ref settings IMO.

But first when that happens quit Prime and run it again and see if it happens again to discover a pattern.

You guys and your dam 45nm chips @ 4+ ghz makes me sick. I am stuck with this old 65nm quad and can only hope to maybe just maybe I can touch 4ghz with water. Seriously though you guys are getting some pretty sick clocks with these UD3 boards. Keep up the good work.

Where's the UD3R BIOS? The latest one? I have a lazy streak that seems to get worse when there are so many threads going on about these Gigabyte boards ...
