GTX 780 SLI smoke smell

post #1 of 9
Thread Starter 
Hey folks, just had a quick question.

I have an alienware aurora r-4 system that I put 2 GTX 780s into. They are very very snug however. They operate fine with MSI afterburner however yesterday I used a different tool. I used EVGA Precision.

Now, I have been told that the 780s use a stock boost as long as the temps stay below a certain level. Well, MSI afterburner only had the clock speed at about 950ish, where with precision x it was 998. I know it can go higher, so I raised the temp target on EVGA precision because I know with my fan curve it will not get up that high. Inadvertently, it raises the power voltage as well. I had done 103%ish before, but I tried 106%. After about 5-10 minutes of play, I got a bad smell out of the case. I quickly stopped and put afterburner back on.

What's odd though is, my cards never even got above 70degrees C. Whats up with that? Just wanted to know if anyone had input on this.

Power supply is 875W.

Probably the VRM overheated.
I've smelled smoke on my brother's GTX 275, it still works fine...

Yes, most definitely. It's not normal. I just wanted to reinsure OP that it doesn't necessary mean he lost the GPU smile.gif

Well it could be that the cards are trying to draw to much power from the power supply which in turn doesnt distribute the power needed properly or the cards are oced to much and the temps are getting to high
