Issue with my SLI GTX 285's.

post #1 of 4
Thread Starter 
I've noticed recently that my case airflow was pretty bad, but not because of my case, but because of the placement under my desk. So I moved my tower on my PC desk, causing a major improvement in temps, which made me happy, I also noticed my overclock(at 4ghz) that wasn't completely stable hasn't crashed on me in several weeks since I've done that.

Until the last couple nights, I noticed something. I was playing TF2, and I noticed the game was acting up on me, then locked up. Not a complete lock-up, if I alt-tabbed back into TF2, it worked again, then locked up. I checked my temp sensors on my GTX 285's, both were at 85C. I turned the fan up to 100%, and the problem was gone. So I started using the 100% fan 24/7 for a while just to check if it'd solve the problem, and it seems like it does.

I'm running the cards at stock, but they seem to be artifacting/crashing at 85C+, or would it be an underlying problem in temp that's making something else act up? Just looking for some advice. This behaviour has been true for the past couple NVIDIA drivers, too.

Another odd problem; sometimes my TF2 will act up, just like that, alt-tab down to Windows. I'll get back in the game, and both my GTX 285's will be almost as if they were idle, as I'm in the game, and I'm pulling terrible framerate and delay in-game(from 150-250 fps to hardly 30), it's almost as if the cards go back to idle/2D mode for no reason and gets stalled there until I reboot(restarting the game doesn't affect it).

Has anyone experienced similar issues or have troubleshooting steps to finding the issue? It's not that big a deal, but has anyone else have had graphic card failure(or apparently) at 85C when they're specced to go much higher?

P.S: One of my card was a GTX 285 FTW, and my other one a regular GTX 285, so my SLI is on stock speeds of the slowest card, not FTW speeds. Just felt like precising that.

with sli 275, tf2 will wobble on screen sometimes, and when it locks up, if you are running win 7, alt-tab and look at bottom right corner of windows and watch to see if display drivers have stopped responding. It happens to me all the time with sli 275, remove and run one card(either of them) and works fine...

Yes I had the same problem with my GTX 295. The game I was playing (I think Crysis at the time) alt-tabed it self, but the difference was that I could not alt-tab in.

I looked at the temps and they were skying above 90 This was with the fan at 100%

I executed Crysis again, and the game ran awfully slow. Found out it was stuck on 2d clocks.

I tried to clean the fans and applied MX-2, but that didnt help much. I just RMA'd it yesterday. Hopefully it fixes the problem

So, its definitely a heat issue. Get a better fan or keep it loud at 100%. Your choice

Thanks for the info! I have some MX-3 lying around, I might get around to doing that, I'll stress test my graphic cards with ATI Tool and/or Furmark to find out if it artifacts/crashes, and if either of them does separately, I'll RMA them, but other than that, I don't mind the fan noise... my case exhaust fan is twice louder as these. xD
