Right, anyone who has one of these will understand the hell of trying to find drivers that work, as the default issued ones are... problematic somewhat with some games as it is. Anyway, that is not the problem. My concern is regarding the ATI Overdrive program. With the default installed drivers, the clock speeds read as : Core- 506 Mhz Memory- 594Mhz Now, the specs for this card means that these specs should go up to a maximum of : Core- 650Mhz Memory- 1000Mhz However, this only appears to be the case when ATI Overdrive is running. The custom-released 6.9's seem to disable ATI Overdrive, which brings up a concern for me. Namely - If ATI Overdrive is not installed, does this mean my card's clock speeds will ALWAYS be underclocked due to no regulation of it? I didn't pay for this card to have it always underclocked, so to simplify my question... Does ATI Overdrive lock the underclocked card speeds as they are if you install drivers without Overdrive as part of the Catalyst?
