Voltage Question

[hkssupra69]

I was just checking the voltages on my computer and for my 3.3 volt stats it says its at 3.6volts. I'm worried about this, can anyone explain what this does for my computer? Should I get a new power supply?

I wouldn't be that worried, I have 3.42, which I know is lower, but it isn't that significant

Check your MB manual. Some motherboards have their defaults for the 3.3V set at other voltages. For eg, Asus has the crazy habit of setting the IO voltage at 3.56V instead of 3.3V by default.

I have an ASUS p3v4x and I'm gonna check my manual in a bit but I've been having a heat problem with my cpu and I was wondering if the voltage being this high is one of the problems, and I'm still wondering if this is gonna have any long term effects.

Its an ASUS thing. For some reason they do this on just about all their boards. AMD has specifically complained about the setting on the A7V. Reduce it to 3.3 and if your system is stable, leave it there.

Mine is at 3.6v as well...and I havent adjusted a thing. Its an asus cusl2. Should I use the jumper and bring it down? In the manual it recommends the user to leave it at default...so this is a good question. waht should we Asus ppl do?

There is no problem running it at 3.6V.

Also, that voltage is NOT the voltage of the CPU. it is the voltage of the Chipset and the slots (PCI/AGP) but it never gets into the CPU (at least not on modern FC-PGA and Slot A chips). It does control the cache voltage on Slotted chips tho.

So-- heat problems are unlikely to be caused by increased IO voltage. They do increase cache, chipset, PCI and AGP stability (and sometimes temperature).

Don't worry about it too much.

This isn't limited just to Asus mobos. I have a Soyo 6BA+III, and my +3.3 V setting reads 3.54 V. Its been like this for quite awhile, and I haven't had any problems.

My +3.3v is at +3.55v on a Soyo 6BA+IV. No problems to report.

I know, on my Abit BE6-2, they did a bios update early this year to provide more power for the problems they were having with the Geforce video boards... They changed it from a default 3.3V to a default 3.5V... I dont know if other manufacturers have done the same thing, but it appears they have... Seems like a cheesy fix, but, oh well...

My CusL2 is running at default of 3.52 as well, this helps o/c as well.

Hmm, no its not.. Thats the DIMM's (RAM) voltage draw, mening your ram is running at 3.5 volts, and not 3.3 volts.

uhh oh yeah.
its the RAM voltage also..

Thanks for reminding me.. I forgot to mention that.
