My first EVGA GeForce RTX 2080 Ti XC ULTRA did the same thing after a moderate OC. After I kept trying to reset to default setting and even reflashing BIOS it just went black screen and 100% fan speed. Nothing I could do but to exchange it.
Yup, just happened to me. Card is now completely dead after a cold reboot. Had to switch to onboard.
These cards don't last....
Yikes. How about selling the one you get back and going with a 2080S or something? Maybe you won't have the same issues?
I have a big bang house. I had all the materials for my new house brought in and dumped on a vacant lot. I took a stick of dynamite, lit the fuse on fire and tossed it into the pile of materials. BOOM went the explosion and when the dust settled I had a new house! Amazing isn't it?
I don't think it has to do with general 2080 ti, I think it has to do with these non FE models. Most of you will dislike what I say, but this is why I go with FE models to purchase aside that I don't really care for all the cool looking plastic all these sub-vendors pour into the cards, i've had nothing but good luck only with FE models and bad luck with after market models.
