The only reason you might want to raise your 'Standard 2D' clocks is so that when you go to game and it changes to the 'Performance 3D' clock rate, it's not as big of jump, and as a somewhat rule of thumb, the smaller leap you make from one speed to the other, insures greater stability. Much like OC'ing a processor you don't want to just jump from 2GHz to 2.5GHz in one stroke, know what I mean?
But then i hit ALLOW OVERCLOCKING and then make windows max it out and it goes all the way up to friggen 470mhz how can that be good for it?
Well you want to hit ALLOW OVERCLOCKING, but just slide the slider back down to the appropriate levels.
What are the stock core/memory for the 6800GT again?
suppose it's 350/900 just for the sake of explination.
When they show those as the advertised speeds, then they mean that's how fast it performas when you initialize a game, otherwise when you're in XP it's clocked down lower.
You don't HAVE to, but is recommended that you increase your standard 2D as well as 3D so like I said it doesn't jump as far when you go to game, but don't OC your standard 2D very much as it's just running windows and stuff like that, and no need to heat up your card just while you're in windows XP...
So Conclusion:
Standard 2D = When you're in Windows
Performance 3D = When you start a game, it kicks into "Performance 3D mode and the core/memory speed jumps up to the advertised core/memory speed you saw when you bought the card"
So in short... OC your Performance 3D as this is what has all the effects on games, 3D bench marks and that sort of thing. After you've found your stable OC on that, go back and just barely up your 'Standard 2D' a little bit just so like I said, it doesn't make that big of a leap and gives it a little less 'shock' when you start up a game.
