    its hard to say how much it will clock as all cards end up with diffrent results.

    all i can say is i have an ati HD4650 600mhz/800mhz now if i clock both ran and GPU the highest i can get stable on both is 640/840mhz but if i just clock the GPU i can push it to 680mhz.

    hope this helps give you some idea and understanding :D

    What are you default clocks?

    Just go up a little bit at a time, and run a stability(Furmark) test after each bump in speed. If it passes a half hour of Furmark's stability test with no artifacts, then bump it up a little more. Keep doing this until you get artifacts, or crashes, then lower it until you don't get artifacts or crashes.

    go up in 5mhz at a time this is what i did till the card craped out hehe, i also notice more of an increase in FPS when i just overclock my GPU core and leave my ram at default.

    If i remember right, im sure i have seen your card being pushed to 850mhz core and 900mhz on the ram but im not sure if that was with custom cooling.

    I got 840/950 out of a friend's one recently. That's not to say that yours will give the same results though.
