Hey all, been a while... Anyway, finally got sick and tired and kicked my AOpen board to the curb (literally). Yes I finally realized that the companies name now refers to the users case (AlwaysOpen). Picked up a P4SDX board and I'm lovin' it! I've been experimenting with OCing my 2.4B. I've gone as far as 2.8GHz (18x155FSB) with the same temps on EVERY setting from 133 up. What gives? Does this happen often?

Here's how I'm testing:

Ambient temp: Approx 80F (the wife's always cold...ugh)
CPU temp idle: 37C (after a half hour with nothin' running)
CPU full load: 51C (after doin' some 3D rendering for 30 min)
Mobo temp: 33C (that's idle AND full load)

I'm using AsusProbe (The first few were monitored with both AsusProbe and MBM 5... they both give the same results.)

So far I've only crashed once and that was from pushing the RAM too fast.

I'm just being careful since I'm only cooling with the breath gas via a Volcano 7+ (@ 5000RPM for all the tests) and some AC3... Oh, and 7 case fans.

Hell, at this rate I could go the full 3.2GHz the board will allow.... am I not running it long enough for proper testing? AFAIK Asus doesn't just calculate CPU temps, right?

If you are not screwing with the voltage, the temp increase will be minimal on the chip, its the northbridge that will suffer with extra speeds.

To save yourself some time (bios, boot, sandra/3dmark, shutdown, bios etc etc etc) use memtest (http://www.memtest86.com/) to find the limits of your setup. The moment you see errors, schtop!

BTW my 2.4b tops out at 2850 ish

Good luck

Thanks for the reply. What speed RAM are you using and what's it running at? Notice and PCI issues at that speed or does your mobo have a PCI lock?
