Asus Probe Giving Alerts on 5 Volt Rail

S

About every half hour or so, Asus Probe is flashing alerts on my 5 volt
rail. I am unsure if this is a system issue, or an issue with Asus
Probe. CPU is currently overclocked to 2.3 Ghz with a FSB of 1024
(stock voltages) and the 6600GT is overclocked @ 550 Mhx core and 1.14
Ghz on memory. Prior to overclocking I dropped the memory down to 333
from 400. System ran for several weeks w/o any problems prior to the
warnings popping up. Any thoughts?

AMD 64 3000+ Venice
1G X 2 Patriot PC 3200
EVGA 6600GT

What is the voltage it's reading?

Possible it's some kind of sensor issue, but most likely your voltage is
really too low.

The voltaget sensor gives a fluctuating reading. I've not seen it drop
below 4.65 and it usually is above 4.8. The odd thing is load on the
drives and the system is totally unrelated to the alerts from Asus Probe.

The "official" +5V tolerances are +4.8V to +5.2V. Anything outside this range is
considered to be out of spec and manufacturers warn of potential
stability/reliability problems if this limit is not adhered to because too low
or too high +5V affects the logic timing.

Your +5V may be momentarily dipping below 4.8V due possibly to mains brownouts
(where the mains supply "sags" for an instant), large spikes or the +5V is
possibly being overloaded (unlikely, but possible).

Why not buy a digital voltmeter and check it yourself? They're cheap enough
these days (around $10 here in the UK), and it's easy to check: the +5V is the
red wire on a standard 4-pin hard drive power connector. Use one of the two
black wires in the middle for the ground. The yellow wire is +12V. With a bit of
care it's easy to (carefully) poke the probes into the plug to make contact with
the connectors. Try to avoid shorting the two probes together as that will
almost certainly kill the PSU and posibly other components as well! (Guess how I
know that!!).

If the +5V is definitely too low, you'll need a new PSU. Do yourself a favour
and buy an Enermax or better still an Antec TruePower (400W minimum) they're
great - steady as a rock!

Aagh! Every time I learn something new... it pushes something old out of my brain!

I have a bit of a different problem with the 5V and Asus Probe. I run
it with PCPTray was well.

But periodically the 5V jumps to 6.021 volts and always to that
voltage. I have the Probe set to update every 5 seconds and the
voltage never stays hi more than the 5 second update cycle.

If I turn off the 5V checking in Asus Probe PCPTray still monitors it
and never jumps up. If I have it turned on in ASUS Probe, PCPTray
does show the voltage spike.
