How much is a safe overclock for a stock 9600 XT and can someone give me a link to a vid card OC guide?

normal is 500/300

I put on overdrive which is 527/300 and it was fine.

How much do you think I could get out of it on a stock cooler?

Btw, its 32C idle which i think is fine.

I've been using ATI tool to detect the max Speed.

Right now its around 573ish and has taken over 1hr 20min

In wonderng how safe this is and will the process stop automatically when its done or is it done manually?

Edit: Also, how much does memory speed impact the performance anyway?
