We may get more when we start tweaking the NB. I'm not sure if its the CPU or the high FSB on the northbridge that's stopping us. CPU load temps are around 60c during Orthos. CPU is running 1.45 volts.
The early results others are getting seem to indicate that the engineering samples were perhaps cherry picks, to a degree. I'd be a little surprised to see 4.4 routinely hit on air. I'm guessing 3.8 to 4 will be more of a norm.
I have reached my target of 4.5GHz 500FSB 1:1 w/ RAM last night. I had to crank the voltage up somewhat high(1.4375V) and it causes the temps to be unreasonably high (65C+) to keep it there. The system remains quite stable playing Oblivion, Counter Strike Source and benchmarks, but under Orthos Prime SP2004 it cannot even pass a minute of small FFT testing on both cores. I will probably back it down to 4.25 and keep it there.
I got it there w/ the following:
PCPower&Cooling Silencer 610
MSI P35 Neo2-FR
Mushkin PC6400 996533 rated 220.127.116.11 2T(set to 18.104.22.168 2T @ 1000)
Thermalright Ultra 120 Extreme w/ S-Flex 63CFM fan
