New build for crunching. The plan is to put an X5670 ot X5660 in it.. For now this is what's going on using a stock intel air cooler: With Prime95, temps top out at 93c (core 2), using RealTemp. Running BOINC, no more than 80c. All I've done so far is update the MB BIOS to 83, and mess with the Bus Speed. The MULTIPLIER in BIOS won't go any higher than 20, though it shows 21 on CPUz. If I go higher than 180 MHz with the bus speed, it's unstable. Any advice?
