      At first, I thought both graphics cards were working until I opened task manager and saw that one of the graphics cards was not working at all.
      Two cards selected during setup, why? How to make multiple graphics cards work at the same time?

        That’s weird, it should automatically split the batch between both cards. I used to run 2x 1080Ti (no link) and it worked just fine.

        Have you tried raising the batch size?

        Do you have a bridge between the cards, like NVLink or SLI thing? I’m not sure its well supported, so if you have one you might try removing it.
