I ran into a problem regarding having two GPUs as well. I have two gtx 1080. Both show up in system devices. When I have the latest, but wrong driver (v595), the plugin and everything else sees both GPUs, but obviously get the can't communicate error. When I install the correct driver (v580), The second GPU disappears everywhere except in the system devices. I was on unraid v7.2.4 and switch to 7.3.0beta2, but that did nothing. I have tried both independently without problems. I have switched the cards around, I have tried different gpu slots (all me slots work when using one card). I have tried messing with every BIOS settings, I have updated to the latest, bios, but nothing. I have had both working in the past (around a year ago), but just recently put the 2nd gpu back into the server and ran into this problem. In the logs, what I find is this error.
