Artifacts in games. Can't figure out if I lack power or the card is toast

I have an EVGA Nvidia GTX 780 ti SC ACX, the superclocked one with EVGA's fancy fan setup(this one). One day I decided to check Arma 3 out after a long while of not playing. About 2 minutes into the game I started noticing artifacts(made a video). It didn't get much worse as depicted in the video, but the game crashed as well several times. Also got the windows error: "Display device has stopped working and recovered successfully" in the bottom right corner. So I started diagnosing.

Ran GPU-z, HWmonitor and got Unigine Heaven 4.0 benchmark. The benchmark pushes the card to its max(as did Arma 3). About 1 minute into the benchmark the same artifacts start appearing and shortly after that the benchmark stops responding, the screen starts flashing from black to back into the now frozen benchmark until it finally times out and we get the "<application name>.exe has stopped working". Tested again, same thing, I can never get farther than maybe a minute or a half into the benchmark.

Also unigine spit this interesting error once.

GPU-z reports GPU power consumption at 100% when the benchmark is running/playing Arma 3. GPU load is also maxed, ie 99%. Temperatures stay around 78C - 83C(172F - 181F) when playing Arma 3, same for the benchmark, so according to the sensors the card is not overheating. I also physically touched the card, 78-83 is about right.

I also tested my heavily tweaked Dark souls 2, same thing, due to its tweaked nature it pushes that card to its limit and the same artifacts start appearing. Also tested Crysis 3, same thing. Artifacts do not appear when playing non-demanding games(default settings Dark souls 2 for ex. gpu usage is around 56% then, no artifacts appear).

Also tested the card in a completely different computer, same thing, Unigine crashes with artifacts and games have artifacts. I have a Corsair TX750v2 750W and the other computer has a Corsair CX750 also 750W.

So, is the card getting not getting enough power or is it borked? 750W should be plenty for this card. Should I RMA it?

Thank you for your input!

  1. Might want to lower your memory clock. The VRAM is either overheating or the frequency clock is not entirely stable at the operating temperature.

    If you bought it new and still have warranty info, you might want to RMA it. it isn't suffering from lack of power. You can test by dropping the memory clock back to factory specs since this card is OC'd from the factory. Just go back to the reference frequency and see if you can make it happen.

    The card is at factory settings(factory overclock, havent tweaked anything myself).

    Ohh, I know. The SC is a superclocked non-refernce 780Ti. You can use software though, to back off the frequency of the VRAM to 780Ti reference levels. While the card may not be over-heating, it is running hot under the most demanding titles. If you could lower ambient temperature by improving airlfow/cable management, it might help a little.

    If you can't change your ambient temps, then the next best thing to do is back off the OC a little(if you want to troubleshoot). Otherwise, just RMA it.

    Yup, 780ti reference settings and not a single artifact in sight. I'm just gonna RMA it, it's not even 6 months old. Thanks for the confirmation!
