Hey i bought an Inno3D iChill GeForce GTX 780 3GB HerculeZ X3 Ultra to put in my Dell t3500 workstation. And it works just fine until i fire up overwatch or passmark or any other application that stresses the GPU.

I checked the temps, it stays under 60 degrees at all times.
I switched my PSU to a 700 watt PSU to rule out a shortage of power.
I updated my driver, no change.

At first i thought the cpu was overheating, but it stays under 55, so that's not the case either.

I used to have a gtx 780 from ASUS in my Dell t3500 which worked very well, no issues whatsoever, but i sold that a few months ago because i was short on cash :p So now im trying to rebuild and the guy gave me a good price on a peer reviewed website (he had 1000+ satisfied customers) so i doubt that the seller screwed me over. I must be missing something here.


Kind regards,
Xander

the strange thing is that the ASUS gtx worked like a charm and this one works fine until i stress it, it really seems like an issue with the card itself, i couldn't find a bios update for it sadly :/

edit: the gpu fails (black screen, gpu fans on max ) whenever i stop stressing it, so i get a black screen when my benchmark finishes it's first 3d test and i get a black screen whenever i finish my round of overwatch and i get a blacks screen when i close down fallout 4 or civ vi.

Very strange problem but at least now its specific enough to try and find an answer.
