3.3V CORE voltage on P4C800 Deluxe

I just noticed today that my 3.3V under CORE voltage in the BIOS is running
at 2.96V. I discovered this after running the ASUSProbe utility. It was
beeping and telling me that the voltage was out of threshold. I tried
bumping up the threshold to 15% (default was 10%) and it still had problems
(I know changing the threshold is for the alarm, and does nothing to the
voltage rate itself).

Does anyone know how I can get this back to 3.3V? Should it be 3.3V?
I've never had a motherboard complain about this, nor have I ever had to
fiddle with the voltages (I'm not an overclocker).

The BIOS doesn't let me change it much, when I say much, it gives me two
options, the current voltage (2.96 or Disabled).

Not sure what harm this will cause, but I want to be safe and keep things
running where they should be....

Thanks,

The tolerance for Vcore is +/- 10%. Subtracting .33 V from 3.3 V, 2.96V is
just below the lower boundary. A relatively lower Vcore is not going to be as
harmful as one that is higher. However, it is always better to see readings that
are significantly closer to average. The PSU is suspect. Replace it.

+3.3V isn't vcore, and the tolerance is +/- 5%. I find it hard to
believe that the system even works at 2.96, a monitor error seems more
likely.
 
Hi,

I had the same problem with A7V8X.
I replaced the power supply and no problem anymore.

The 3.3V decreased to 2.8V and I also had the alarm in ASUSprobe.
In my case, it was clearly a problem in the PS.
It was low cost tower "Sweex" with 300W PS.

Try to replace the Power Supply by a good one.
 
I think I have the same problem, I am having many problems with my
geforce3 on my p4p800 mb. The rating in the bios shows about 2.8v for
the 3.3v input, is this a mainboard problem or a power supply problem
?
