I bought an EVGA 6600GT about a month ago and it runs the only game I play (MOHPA) great. But then I got curious about overclocking it so I downloaded the Coolbits utility. When I finally got to the part where you can overclock it I got coldfeet because I didn't want to void the warranty but I couldn't help but notice the core clock speed was set at 300 but it's supposed to be 500(see image below). Does anyone know why it's set lower than advertised?
