Hello everyone. I have already overclocked my Sapphire Radeon 9600XT 256MB, but I wanted to know what its limits are. I have been told that it is a good card for overclocking. But when I opened ATI Tray Tools it wouldn't let me overclock. I then downloaded ATITOOL and I am now able to overclock. The default gpu is 500 and the memory is 300. Right now I am running the gpu at 527 and the memory at 333. I haven't seen artifacts, so I would like to overclock it more but I am afraid of frying my card. Has anyone overclocked this card before? What kind of limits does it have?
