Zalman 7700cu is the cooler with Artic Silver, got pretty good temps I think. @2.7 29/29 idle 49/47 load
I fiddled with it more last night and was able to get it to run well using the auto voltage thing gigabyte has.
333x9 Was prime stable 8 hours.
I had to reset the memory timings. I thought i could get them to work at 667mhz with 4-4-4-12 timings, even with the voltage set at 2.1v(1.8+0.3) it would not do that. So i set the memory back to 5-5-5-12 and set the multiplier at 2.4 (4:5) and it's running well at 800mhz, though still only if i let the board manage the voltage.
Since I don't trust the boards automatic voltage, I'm going to try what you suggested.
The 2x1gb set of OCZ Gold ram is 5-5-5-12 800mhz @ 2.1v
The 2x512mb set of OCZ Gold ram is 5-5-5-12 800mhz @2.0v
I will try runing the voltage at 2.0 if that doesnt work 2.1, slight undervolt or slight overvolt on either set should not bother them.
