When you opener the tuner to the Overclock page, where it shows core clock, shader ect... How high is the card able to run? Does RT determine this itself and display that blue bar or is there a limit that most cards can handle?
no to tell the max you need 3dmax06 and run the tests and if you see any artifacts then take it down about 10mhz also only go up by 1 every time one time i went up by more then 1 and my whole graphics card stoped working but then i restarted and everything was fine that was a pretty close call also for how high it can go depends on the card
