I have an rx 580 armor OC that is also stuck hashing at 21 and I can’t figure it out. If you find a solution let me know.yes :/
Do you have original or flashed bios on your cards right now?
Maybe try shutting down and running one card at a time and see if you cAn isolate which one isn’t working well and causing driver software to not open?
One thing I haven’t tried but need to is swapping out risers for my slow GPU. A shot in the dark. It maybe that’s an issue?
