8800GT or PSU

post #1 of 16
Thread Starter 
hi ..... this is regarding my GPU & PSU the PSU is a coloursit 600w with an apparent 30A on the 12v cost me about $40 20gbp shipped ....on 3dmark06 i seem to get the same score stock as i do OCed ...??
and when gaming the card always seems more choppy when OCed
when its stock its flawless ...
my bios reads 12v rail @12.05v but speedfan & everest report it @11.30v
is it possible that the card is undervolting when i OC..?
i dont know if OCing in rivatuner actually requires more power the higher the clocks go im sure it just increases the cycle rate of each clock not add power

so would changing the PSU bag me a better score or is it my GPU not improving from the OC due to ....well i dont know
any thought would be apprieciated

skunksmash. What kind of 3dmark score you have? I haven't used COLOURSIT 600W psu before but it should be fine if it has 30A on 12v rails.

That doesn't mean anything.... The PSU could be exhibiting excess ripple and slowly damaging components. A cap could blow one day and take you the video card. Saw this happen to someone last night. $20 PSU to power a $600 system. Bye-Bye $250 card.
Once again...

Not bad. Back GPU to 700/1800/975 and give it a try. Maybe it is time to get a new PSU.
