2900xt performance issues?

post #1 of 5
Thread Starter 
I own the ATI 2900xt. I am currently using both PCIex16 pin connecters to power the card. I have an 8 pin but will not reach to the card.

but my question is. I am using the latest catalyst and drivers 8.3 i belive
and I dont have the Overdrive option. is it because I am using w 6 pins?

my other question is. the card specs say i should have I should have a memory clock speed of 1600 and a core clock at 780. this is what it accually is running at.

any thoughts as to why this is.. I really want to get the full benefit out of this card.. and eventually run 2 in crossfire.

any help in this matter would be greatly apprecuated

You need the 8pin to oc with od and the speeds you see are 2d.

BTW you can oc using ATItool or Rivatuner.

The setting you see is when the card is just in 2D. When you play a game it will to the stock setting780/1600. And yes you need the 8 pins to unluck the overdrive.

Use rivatuner to monitor the clock speeds whilst in game, they clock down immiediately if you minimize the game.
