    Sounds like your power supply is getting raped. What is your power supply, and current system specs?

    The P4P800 and P4C800 both read the 3.3V line much lower than they actually are. I have 4 of these boards and they all do the same. With my 3.3V rail tweaked to 3.6V (tested with DMM) the bios reports 3.33V.

    so you mean it is just fine? but i'm worried because i heard that it should not be less than +-5 tolerance, meaning 3.2 - 3.4... haven't you encounter any problem with this setup?

    What you really need to do is test the voltage at the AUX 6 pin connector with a multi meter. Bios readings are almost never accurate so I never go off them. I have a P4P800 running in the other room right now with the bios/MBM5 showing 2.84V for the 3.3V line, but I checked with a DMM and it showed 3.31V...soooo nothing to worry about :good:

    sorry to borrow the thread, but i'm experiencing a similar problem. i'm running on a p4 2.8c ,radeon 9800pro and a thermaltake 300w psu... i get the same 3.3v out of threshold notice with the asus aiprobe... but then whenever i run anything that even remotely resembles 3d graphics e:g winamp visualization, i will slowly experience artifacts that will eventually fill the whole screen.. the same goes for games. the comp will then shutdown or restart and refuse to boot into windows. what can i do?
    thx guys...

    I'll back that up. Very reliable PSU for the money; I used those exact units when I refurbished the workstations at my work. Not a single failure so far, and they've been rock solid.
