Ok....first my system:
MB: Asus P4C800 (not Deluxe, just P4C800).
CPU: P4 Prescott 3.2GHz D0 stepping.
RAM: 2x512MB Gskill PC4400 TCCD chip, 277MHz @ 2,5-3-3-7
CPU cooler: Asetek Waterchill Antarctica, dualradiator with 2 120mm Adda fans and the Hydor L30 pump.
VGA: PNY GeForce 6800 Ultra
PSU: OCZ PowerStream 520
...and some other stuff.
Anyhow....this system should be able to clock pretty well I think...but still, something is holding me back. I'm guessing that it's settings though, and not hardware.
I run my memory in 1:1, since they are guranteed to do 277MHz with decent timings. The power supply is one if the best on the market. The temp on my CPU under full load with 1.55Vcore and 240 FSB is stable at 40 degrees.
Anyhow....If I run Prime95 with my current 240 FSB I get a critical error after only a few minutes. I have tested another motherboard, and there I could go higher on the Vcore, when I set 1.65V in the bios, it showed about 1,6V on the monitoring, and then I could run Prime without problems at 250 FSB....with my current Asus MB it wont post over 1,6V in bios, and that is about 1,55V in the monitoring.
What is the reason it wont post with over 1.6V? Like I said, that's only 1,55V anyway...and I need more to go higher. What should i do?
