I have enabled SLI in my system with two 8800 Ultras, but how do I see if they are working? How do I know that both my graphics cards are running?
 
Bump, also, what kind of software should I use to adjust my GPU settings and to monitor temperatures?
 
To see if SLI is working run a benchmark test both before, and after you activate SLI. If your frame rate goes up in SLI mode, its working. ;)
 
Yes there is.
Control panel.
Under 3D, up at the top tool bar, open manage 3D(or something like that)
Check off "SLI indicators"
This will show you the load balancing bar on the screen which indicates SLI is functional.

If what I said was confusing, just go to the help section in the control panel in 3D.:D

Ntune is nvidias answer to the temp monitor and OC of the cards, but it is buggy as hell. It has crashed my system more times than I care to comment on.
Save yourself the headache and use RivaTuner. When I emailed nvidia with my problems, they said my best bet was RivaTuner. I use it to run the fans on my cards, and adjust OC. Unfortunately, at present there is no way to control both cards independantly.......but contrary to popular belief, if you have two cards with different clock speeds, they will run at those speeds, not at the lowest common denominator.
 
When i check off show sli indicators, nothing happens...

also when i was running the cpu test on 3dmark06, i got framerates between 1 - 3... is that normal?
 
lol Yes, for CPU benchmark, its normal. However, its not the CPU benches u should be worried about, run all 3D benchies in 3DM06, I dunno what #'s dual Ultra's these days normally pull out in 3DM06 though.

Probably at least 15k+, so if you are getting like 13k or under they aren't SLIed.
 
after running 3dmark all it says is submission failed when i try to view my results online...
help?

you need to log into their site and delete soem of your other results. if you have the free version you are only allowed 5 results.
 
I'm actually suprised your 850W PSU can handle two OC'ed Ultras.

As for verifying SLI, try downloading nHANCER app. (http://www.nhancer.com/)

... also something from SLIZone.com
The SLI visual indicator is not a separate rendering mode, merely an extension of whichever is currently being forced. This function works best and most easily understood when enabled with Split-Frame mode, however it will work with Alternate Frame rendering as well. For SFR, a horizontal band will move vertically, depicting where half of the visual workload meets, and depending on the concentration of visual detail the position of said line can differ. In a basic cuboidal room with no objects or actors, the line will hover right around the middle of the screen. In a room with stairs, windows, ceiling fans and light fixtures, doors, support columns and whatnot, the load balance is going to be thrown way off since there is more visual content in one part of the screen than the other. The visual indicator for Alternate Frame rendering modes isn't as simple nor as helpful, though they are still functional. For AFR, an empty vertical bar is displayed on the left side of the screen with a green box in the middle. As the amount of scaling increases, the box will grow accordingly, and of course as the amount of scaling decreases the box will shrink. When the box is small, this means that the application is being restricted by the CPU, but when the box extends the height of the monitor it indicates that the video subsystem is holding the system back. To enable or disable the SLI visual indicators, open the NVIDIA Control Panel, and in the "3D Settings" category, under the menu aptly named "3D Settings," you will find this feature.

Or, to be more succinct. After you enable SLI Visual Indicators, you'll need to play a game. If you see bars moving up and down (or side to side) during the game, SLi is working.
 
I thought it would be intuitive that you needed to do 3D rendering for the SLI indicators to show up from the control panel options.......sorry I didnt include that bit.:D
