Possible to turn off one card in an SLI setup?

[pjyelton4476]

I currently have dual nVidia 6800 GS's running in SLI mode on my system and I was wondering if there was a way to turn off the second one while not playing graphic intensive games. Without reaching into the case and taking it out of the slot of course

The reason I'm asking is because the fans are rather noisy, and since the dual SLI mode is only needed for a couple of my games it would be nice to cut back on the noise when doing simple things like surfing the internet.

answer: you can't

but there's an alternative way...use rivatuner to change the idle fan speed to as low as possible without frying the cards

Thanks, I'll give that a try.

Download a program that detects the difference between 2D and 3D applications.(Rivatuner may do this, but I am not sure. I use ATI Tray Tools, but it may not work on nVidia cards) Then have for the 2D mode, your gpus both run at the lowest possible clock speeds without causing a system crash. At this speed, you should be able to turn the fans down to a silent level, possibly even off. Then have it set to go back to normal clocks for a 3D application.

Rivatuner FTW!
