+12.0 and -12.0 v question

Looking at my system, I was oc'ed on a xp2000 thorton to xp 2600+ which is from 1669mHz to 2089mHz

Anyways, I noticed that my voltage on MDM5 is running a bit higher than usual, 12.35 and 12.35 on the + and - respectively. I was wondering is this suppose to be as close to 12.0 threshold as possible or are the # correct?

Here is my setup

AMD XP 2000 Thorton oced to 2600
2 x crucial 2100 oced to 2700
1 x k-byte @ 2700
Asus A7N8X deluxe
Antec SLk-3700 BQE
Antec 350 Smartpower

I'm running the soundcard using builtin and also the lan.

Thanks in Advance
 
Well, sure, technically it should be 12.00 volts at all times, but it's quite a bit better for you to be a bit over on any of the rails than to be under. And, yes, 12.35 is within the "normal" range. Try running 2 hard drives, 2 optical drives, and 5 or 6 large fans (by large, I mean 120mm, not 80mm!), then come back and tell us what voltages you're running! 😀
 
haha, yes i am back, that is what i am exactly running

2 hdd, 2 optical drives, 1 floppy and 1 120 mm fan...
 
It's supposed to be at a constant 12, but that is impossible. Usually they up the voltage a little to give it head room so that it won't dip below 12. Connecting hardware to the powersupply drains a little voltage and other factors can mess with voltage regulation such as heat and interference.
 
A variation of 5% is considered safe. That would be 12.6 volts. By the way, modern comps don't use the -12v line.

Click to expand...

how about the -5v? because if those two aren't used, you could 24v- and 17v-mod a fan... :evil:
 
Right. The -5 is not used. you can run a fan at 17v, but the fan may fail very shortly. Also, the current carring capacity of the -5v line may not be enough.
