ok first you open it. Then click on one of the buttons,either find max core or find max mem. This will begin to up the speed then stop and see if it is producing any artifacts. After doing the mem and core(make sure there under the max) save it and next time you want to play just open ATI tool and load the save:D
So I have to load up ATI Tool whenever i want to play a game with an overclocked video card? Also, what is a normal overclock with a standard 9800 pro fan?
