I am new to the concept of SLI. The problem that I keep running into is when I try to play games. Mainly I play CS:Source. I would be playing for about 30minutes and then the screen goes blank and the sound gets choked up and repeats until the screen goes to my desktop.In some rare occasions the blue screen of death would show up and I end up restarting. But other than that once the game shuts down I get an error msg about an APPCRASH. I would also get the same thing for COD4. I have read many forums and have taken their advice by.
So far I have tried:
1. Reinstalling Vista
2.Reinstalling the Games
3.Updating to the newest drivers for MB(nForce v.15.23 WHQL) and GPU(GeForce v181.20)
4.Checking if both GPUs were working
5.Used RivaTuner to turn up GPU fan speed for possible overheating (during idle stays at 50c and during its peak it reaches high 60c)
**Here is the weirdest thing. When I do not enable SLI mode and run a game on 1 GPU it does not freeze. But after I am done playing I still do get the occassional APPCRASH error.
Please if anyone could help me find what the problem might be when trying to run SLI for my computer games?
1. Do you have proper cooling for your overall computer case? (The problem could be that, if SLI'ed, both video cards putting out heat into the case is causing an overheating issue with another component.)
2. You said the game works on one GPU. Have you tried t run it on both GPUs individually?...or just one of them? (Move your monitor to the other one, play the game, and see if the second card could be defective.)
3. Did you overclock your machine? What about the video cards? (Even on accident while using RivaTuner.)
In any regard, my first thoughts are Heat and Video Card Instability.
