I`m a little scared about my video cards

Sometimes it just start appearing a lot of artefacts in the screen gaming, no overclock, nothing

I have here 2 GTX 780 SLI, i only tested at Payday 2 game till now, i can play for hours without a problem, and then it starts, if i close the game and start again no issues, or if i use 3dmark no issues either

i have the TDR issues here related to the Nvidia drivers, that will be fixed in the new one that will be released in the end of August

But i`m really sad thinkinbg that some of my cards might have a problem

Is there a way to test it without putting off the machine one or another?

And what i described means a hardware issue?

My system is an i7 3770k @ 4.5

PSU CoolerMaster SilentProGold 1200w

The cards are EVGA SC Edition

Thanks

I suggest you do some stress testing, individually, to try and replicate the problem, it might be that one of them has a problem. Take out one of your cards and run the valley benchmark ( http://unigine.com/products/valley/ ) for a few hours, to replicate a long gaming session. Make sure everything is setup (fans etc) like it normally is when your game. The valley benchmark shows a little readout in the corner with your temperatures, check that periodically to make sure it's all ok.

If the temperatures go too high or the artifacts occur, come back and we can go from there. If nothing happens, try the same on the second card.

No Overclock, they have the factory OC so i did not made anything

Temps about 55C 60C, i use the fan at 80% to cold the cards, really noise but i don`t care

Thanks

But do you think it`s related to a hardware issue?

Is there a way to test each card individually without taking of the card?

Edit:
Let me ask you another thing

The top card goes to 1071Mhz with GPU boost and the botton one to 1084Mhz, this can be related to something wrong?

I mean, they have the same bios, the same revision.... was not supossed to go to the same clock?

Thanks

Well guys, runned the Valley in the max possible for 3 hours and nothing happened, runned with SLI off but with both cards attached so just the first card was running right?

No issues at all, what should i do now?

Well made the same with the second card and no issues too

Trying Furmak now, till now no issues, temps normal, with SLI off but both cards attached, is it really enough just to disable SLI and switch the monitor cable to test each card individually?

Thanks

Anyways i did some tests, see if you think it`s enough

Valley benckmark: SLI off both attached in the MB, 3 hours wich card no issues or artifacts

Furmark: SLI off both attached in the MB, 3 hours wich card no issues or artifacts

3D Mark 13 (I have the full version) - SLI off both attached in the MB, 5 hours wich card no issues or artifacts

And one more info:

MY CPU is Overclocked: 4.5 with 1.23 vcore LLC on Turbo, do you think it`s ok? It`s a 3770K

Thanks
