I noticed that the memory clock for the ATI HD 3850 was 1658 Mhz. Mine is at 829 Mhz and I can only Overclock it it as far as 1117 mhz with ATI Overdrive. I'm guessing that the card in the VGA charts is Overclocked in the memory section but not in the core's clock? Shouldn't they tell when it is an OC edition? And they almost always OC the core along with the memory so that doesn't really line up.
