SLI issues

[AshesOfThePlope]

well i recently purchased 2 EVGA 9800gtx ssc + cards

at first all seemed ok, then i started to play games and see how much performance i gained and to my surprise it wasn't much at all,

my first thing is when i check my fan speeds (using the nvidia Ntune CP) right after my computer starts says its 0% fan speed, its not hot but i just found it odd, well then i jacked both fans up to 100% and i put my hand behind my computer to make sure they were blowing out alot of air and one card was blowing a considerable more amount of air then the other

second when i ran a GPU test on crysis all high settings 1680x1050 no AA i got an average of 27FPS(i find that hard to believe based on benchmarks iv seen)

iv reformatted, tryed my system with windows xp SP2 and windows vista SP1 and got the same outcome, im figuring maybe the one card is not working properly and its not making the SLI performance noticeable

Specs
Asus striker extreme MOBO
intel Core 2 Quad Q6600 2.4Ghz
2Gb DDR2 ram
running windows vista w/SP1 ATM

Swap them out and do a clean driver reinstall.

iv already tryed them on a clean install of windows, i dont think this is a driver issue

By swapping them out, I mean have you tested the cards individually?
Also, I have had a bad SLi bridge in the past.

 

[AshesOfThePlope]

no i haven't but il try that tomorrow, is there any programs i should test the cards on to make sure there working properly?

ok ashes which driver you use , and in crysis i think you fbs must be around 35 , did you try clean drivers from registry , try also remove overclock programs and try again

 

[AshesOfThePlope]

im using the 177.79 driver and i have no overclocking programs installed, and i didn't have any previous driver installed before installing the 177.79 drivers

 

[Hayder_Master]

ok try the 177.92 sure you see some different

you have to pass the SLI configuration test to get in. If its set up correctly you will get in, if not it will say you failed to get it installed correctly.

well i tested the card's individually, one card averaged 30.99 and the other was 28.65 FPS in the crysis GPU test, tryed them both again and averaged 30.05, tryed them both with the 177.92 drivers and got the same result

PS
i registered for that SLI club and it worked fine
