I’m using an old PC to set up a mining rig, currently it’s working fine with a 3070 and 3080, I’ve got a pair of 5700XT’s to add but as soon as I add a third, it’s not recognised at all, only the other two cards. I’ve tried switching between slots, cards, risers and still no more than two cards.
I’ve had a look at the settings in the BIOS and can’t seem to see anything relevent. Issue is the same for windows or HiveOS
Does anyone have any suggestions? Would be greatly appreciated!
