Overclocking differences?

Hey guys, ive overclocked my 4830 from 575 core clock to 640 as the mem from 900 to 990. Ive set the fan to highest so it wouldnt overheat while i play. Once i start playing i still get the same fps as the stock clocks? How is this?

Any info will be great guys! thanks.

Well to be honest that is not a very hefty overclock. You really wouldn't see much with the naked eye with that.

Yeah. You wouldn't notice it but that overclock would probably make the average or minimum fps a little higher. Don't be afraid to really unleash that sucker! Use the ATI Overdrive feature in the Catalyst Control Center. There is a part called auto overclock. Use that and it will take ur gpu to the highest stable overclock possible. It works really well and that's what I did for mine.

The max I can get my 8500 GT to is 690 clock 474 Memory and 1380 shader Bandwidth 15.2 GB/s when org. is 12.8 GB/s which i think is pretty good .
