I have a small rig with 3 1080TI card on a asrock pro btc R2.0 motherboard.
For some reason it only detected my 2 cards (2 out of 3). When I plug in the card solo, it does not work. I tried connecting it to the motherboard itself, does not work. It’s not the risers as I tried replacing the working card on the riser with the bad one, and still does not work. It has power and fans are turning.
I took the card to the computer shop and they plugged it into a windows PC and it worked like a charm for some reason.
Anyone experienced this kind of problems?
