My asus eah5750 is overclocked to the limit of ATI Overdrive and its still never above 70C using 3DMark06 and Crysis as a Bench. So my question is I want to keep going what do I use? Please note: ATI Tray Tools crashes my pc, Riva Tuner and ATI tools don't seem to support overclocking my gpu, and the Asus Smart Doctor that came with the card doesn't go any higher than Catalyst. I don't want to overclock it in the bios because that will make it run at those speeds all the time where as catayst runs the gpu at lower clocks until its needed right?
