Intel D875 mobo, false cpu temp alarms (I think)

I recently built a system with an intel d875pzlk motherboard and a 2.8c cpu, 512MB PC3200, Win XP Pro. Now all my temps show normal 79-84 F, but randomly the intel active monitor will pop an alert that says the cpu temp is above the threshold. It will say that it is 235F!!, this is always accompanied by it saying that the voltage is low, MBM5 & Intel active monitor shows the temps & voltage as stable at normal specs, and in the intel active monitor log, the temp alert and voltage alert only lasts about a second. I am pretty sure that this is a false positive due to the fact that it happens all of the sudden, 80F jumps to 235F, and it only lasts a second.

If it was a hardware sensor problem, wouldnt both programs catch it?
Does this indicate that it is a problem with intels software?
Can anyone help me shed some light on this?

if the voltage to the proc goes low and the temp goes up.... that doesnt make sense at all. it has to be a false reading....

imo it might beable to trip like that if the power dips down for a breif second, pending on how the temp chip reads the thermodevice. this would also explain the voltage warning

thats kinda what i was thinking, so it looks like a UPS is in order to see if a power dip is the casue.

thaks for the fast reply!

You might check for a bios update for your board. Flashing the bios often fixes bios reporting errors.
