hi.
I got a question about my psu again. It is a thermaltake tr2 w0093 500w which I've been told is a good quality unit.
When I go to my motherboard monitor, my 12v line is at 11.89v, when I start prime95, it drops to 11.77, and when with prime running I start atitool's 3d window it drops to 11.55!!!!!! Is this drop too much??? cause although I'm getting good overclocking results with my cpu, my gpu overclocking didn't do as well. I'm starting to think my psu was the problem all along, cause I can overclock my gpu (x1800xl) to 600/630 from 500/500, and it will run atitool's artifact scanning for hours. HOWEVER, when I put prime 95 in the background my 3d window craches in a matter of seconds!!!!!!!
:-(

I guess it's the psu right?
btw, i've tried changing all my fans from one rail to another but no luck, I've also tried disconnecting the dvd drive and some fans, but I get the exact same crash when running ati tool and prime at the same time with cpu and gpu overclocked (the crash doesn't occur if I don't run prime in the background, and it doesn't occur also if I don't overclock my gpu and do run them at the same time)

The ATX spec allows a tolerance of 5% +/-

That means the +12v rail can vary between 11.4v - 12.6v.

Have you tried increasing the AGP voltage to your card?

5% tolerance, I see, thanks.

I have pci-express and there is no option to increase the pci-e voltage from my bios. I can only increase the card's voltage with atitool. I get good overclocking results when increasing voltages even in gaming but as I said it crashes when prime is running in the background.
