Hey there

Recently I assembled myself a completely new system:

E6750 Duo Core
2x1GB Crucial Ballistix PC6400
Asus Maximus Formula
ASUS EN880GTS 512MB
Antec Phantom 500W PSU

The thing is, after installing Everest, my rail voltages seem rather low: 5V is 4,94, 3V is 3,21 and 12V is 11,76.

This isn't really that much but I've been having quite a bit of problems with this setup without finding a reasonable culprit. I'm now looking into if it could be the PSU, so any help is appreciated.

By the way, I'm completely clueless when it comes to anything regarding a PSU, so please bear with me :) 

Thanks in advance!

Tolerance is 5% per rail. What problems are you having? Using a Digital Volt Meter would give more accurate voltage readings.

I'll second using a more accurate means to test voltage. Invest $13 or so in a PSU tester. Still, those voltages appear to be within tolerance.

I kinda figured that it was within tolerance, but still thought it might be worth taking a look at since they are all low.. But if you don't find it alarming I'll try solving my problem another way :) 

In short I've been having problems with both my RAM giving errors (probably bad), also not being able to install a certain PCI WiFi card.

It's probably my mainboard then :(

go get a dmm to measure the voltage, the software measurement is base on the sensor reading, it could be off
