My 3.3v is constantly at 3.79v. The system monitor indicates that this is a high value. How do I reduce it and at it's current voltage is it determental to the cpu?
Thanks in advance.

All advice here is free.</font color=blue> What board do you have?
Probably the probe is reading wrong. Check it with the PC Heath monitor and in the BIOS setup. If its the same then maybe its really high.
3.3V is the I/O voltage, by which the CPU interacts with the internal components. Well, its almost 0.5V too high. While it wont affect your system in anyway in performance, it might lead to overheating and occassional crashes and lockups. If there arent any crashes occuring after several hours of usage them probably it isnt 3.79 at all, it might be normal within 0.1V or so. Try a different system monitor.

I have msi K7T 266 PRO 2 with an Athlon 1600+ xp. The bios reads the same as the System Utility
3.792 volts. The Utility is called PC Alert III System Monitor. It came with the MB. How do reduce the voltage? What could be the causes? ANY ADVICE?
Thanks.

try using a different mothboard probe like MBM, I dont have the link offhand, you could get it using a search engine.
There is in fact no way you could reduce this voltage, there are very few boards that will allow you to alter the I/O voltage, almost all will allow changing core voltage. It probably isnt the power supply issue too, since there is a regulator on the motherboard that supplies this voltage, its reference is probably way off.
If it isnt affecting the stability of your system, you might want to overclock the system a bit, increase the FSB in steps while the system stays stable. Increasing frequency needs increase in voltage for proper signalling. You can take advantage of this overshoot and increase the FSB to close to 166 (if your memory permits), dont try to change the multiplier just yet. This way you could use he problem to your advantage and have a faster system as well.

well excessive ram voltage does increase stability for overclocking... but can also burn it out or reduce its lifetime.
my old asus a7v133 used 3.56V as default... bit of a cheat if u ask me.
Excuse me for a moment. I need to drive my ergonomic wheely chair over a sheet of bubble wrap!

what if it gets too low?! is this all the same with others like +1.5, +2.5, +12v etc?!?! i use mbm5, and it says my +2.5 is down to 2.3! is this safe?!
peace outz!!!
peace outz!!!
yes, higher than normal voltage will reduce the life of the component, or damage it permenantly. generally memory can handle a bit more than 3.3V, so can the processor but that is not to be done!
the system might not be stable if the voltage goes lower, there are tolerences so +/- 5~10% is okay. Basically, you need enough voltage so that the processor can assert the signal properly. If it cannot, it perhaps wont boot or frequently lockup, crash or reboot!

If you are so inclined, it might not be too tough to determine which part is bad then replace it.
I would guess there is some regulator on the M/B responsible for this voltage. Regulators for motherboards are usually 3 pin TO-220 package. Probably if you could get the part # off the part, you could order an engineering sample (free), and replace it once it came in the mail. If there ever was one thing on a motherboard an amateur had a decent chance of replacing it would be these regulators.
The other cheezy method which could probably be done but I would never do or recomend would be: load that baby down with a potentiometer until the Vo was within spec. The problem with this idea is, well it sucks, but it would work, at least for a while.
