Got a screenie

(It got to 0% only when i paused Crysis to take the screenshot)




Yeah, I'm actually getting worse performance with SLi enabled. And it's not as far as framerate, but fluidity. It almost seems as if information is just not being transferred between the cards fast enough. You know how when your card is too weak it just plain plays a game slowly? It's not that, it's more like stuttering, so something's up.

Another confirmation is to enable SLI Visual Indicator in the Control Panel under 3D Settings.
You will see a thick green vertical bar to the left of the screen. It continuously extends/contracts from the centre upward and downward. The better SLI scales, the longer is the bar. (see pic 1 below for eg)

Also, I recommend you setup a Custom Fan Profile (vs using Default's Auto-as shown by the blue rectangle...see pic 2 below). I notice from your last pic that when GPU1 temp goes up to 62C, its fan only spins at 43% (red rectangles). Perhaps you can adjust the speed faster, matching your tolerance of noise produced. This applies to both cards, not just GPU1.

Have you posted on the TPU thread?

http://forums.techpowerup.com/showth...60844&page=199

The authors of the software hang out there and might be able to help you out. For a while the patch didn't support 4xx or 5xx but then a new version came out, so have some hope yet.

Did you edit the SLI settings?
