I'd just like to know maybe some simple math formulas or ratios for overclocking this card. I did read the ATITool overclocking FAQ/guide, and that did help, but I'd just like to have the knowledge to follow using more than one type of card.
Hmmm. I'm not quite sure I understand your question really...
Overclocking any hardware is more a matter of trial and error testing than applying any kind of formula, or at least that's my understanding...
With stock cooling and stock thermal paste, your card is likely to reach a core speed of around 385MHz to 395MHz and your memory will likely reach 345MHz to 350MHz. With a Zalman VF700-Cu, some decent copper RAM sinks, some cured AS5 and a case fan blowing cool air from outside of the case at the VF700-Cu and RAM sinks, you could be looking at a core of 420MHz+ and a Mem of 375MHz+.
So, with stock cooling it's likely to be an average increase in frequency of around 2.75% and with decent air cooling (as described above) it's going to be an average increase of around 10.5%, a 3.8X greater o/c with decent cooling compared to stock cooling.
When I owned a 9800Pro, I got the core to 418MHz and the Mem to 378MHz with the decent air cooling described above.
Hope this is of some help
