Should I get a new PSU???

post #1 of 8
Thread Starter 
OK, I have had this problem ever since I moved to this motherboard and PSU. (I bought them at the same time.) I can set Vcore is my BIOS to 1.3v, but Speedfan (inc OCCT), PC Wizard 2007, CPU-Z, and every vcore monitoring tool I can find shows around 1.26v! It also jumps around about .02v! Here's an OCCT chart from a 2.0GHz run at 1.3v:

It does the same thing at other volts. 1.65v in BIOS is 1.5v, 1.5v is like 1.4v, etc.

New PSU time? I don't have another PSU to test with...
I do have a voltmeter

i see that you have a CoolMax PSU, i think i speak for most ppl on OCN when i say

you need a new PSU because you have a cool max.

i would never trust a coolmax PSU, as for we have seen many components die because of coolmax PSUs, along with them.


it could be a bios problem, did you try updating your bios to the latest one? but i would Definently get a new psu

I have tried a BIOS update. I've even tried the Rebel's Haven ones.
How do you measure the vcore rail on a PSU?

i measure it with a real volt meter, a fluke master, and i measure it with a load on it, when the computer is on.

you should read this: why most power supply reviews are wrong.

other than that. did you try and call biostar tech support? i've never ran into that problem

coolmax is one of the psu's you dont wanna have...
if its not a recommended brand/psu its probably because its unreliable but not necessarily bad.
I would get cheap but reliable psu (ex.rosewill or fsp = $35-$50) before i start meddling with the voltage...

Hipers are good for single card PCs, I loved mine, but DX10 and/or CF calls for something with a bit more umph. Also, a Sunbeam NUUO used to be the greatest thing ever, so you may want to look into one of those.
