9800GT won't budge past 705 mhz core?

post #1 of 4
Thread Starter 
I just picked up a used 9800GT as a temp solution for a few months and tried to overclock it. I was reading through the forums and people were able to get 725-750mhz core overclocks, my BFG 512mb won't budge past 700 without artifacting. Why?

Youve probably hit the limit for your specific card. Not all cards are capable of the same clock rates even if they're the same model. My 5770 won't get passed 950mhz w/o artifiacting but a lot of people have managed 1ghz+

Every GPU is different, same principle applies to processors. The card you've gotten doesn't like the clocks you're setting it to without a little extra voltage. It's all down to luck on how good your GPU is.

EDIT: If you're really set on getting those clocks, just take the voltage up in small notches to see if you can maintain stability.

This, same card, I couldn't move up more than 10mhz w/o losing stability until i raised the voltage +25mV.
