I just got a used rig from my friend that has been offline for 2/3 years (he said it worked pretty fine back then). It consists of:

- 8x RX580 8gb PowerColor
- Asus Prime Z270-AR
- Intel Pentium® G4400@3.30Ghz
- 4gb of ram (2133mhz)
- 2x Corsair CX750m power supply
- Sandisk 16gb flash drive
- Hive OS (latest version)

When I run only one gpu, HiveOS starts fine. When I plug the second GPU onward, I start to get the error "UVD not responding, trying to restart the VCPU" as can be seen on the image (https://imgur.com/a/JTGAqMw).

I tried to change the PCI-e Auto, Gen1 and Gen2 (only didn't try Gen3). Also tried to edit /etc/default/grub to change the line to GRUB_CMDLINE_LINUX=“radeon.modeset=nomodeset” (also tried radeon.modeset=0 and just "nomodeset").

Not sure if there is another config that can be made to solve this.

Any clued to help!? Ty a lot!
