Overclocking

With Overdrive disabled I was able to get the RV360 core up to a very respectable 580MHz. Even at this speed the temperature never went above 41°C during after any of the tests below. I also managed to reach a very respectable 345MHz on the memory which is even more impressive when you consider that I was only able to get 325MHz on the Sapphire 9600XT Ultimate Edition.

Remember however that Overclocking varies by card so your mileage may vary.

The chart below shows the difference between the stock 9600XT and overclocked 9600XT specifications.
