I have problems building my new rig.
Motherboard : Asrock h81 pro BTC R2.0
GPU: 6 RX480 Nitro 4G +
OS: Ubuntu 16.04 LTS server (not desktop).
Installed drivers: amdgpu-pro
No bios update + default settings.
Risers : http://www.ebay.fr/itm/310897618647
When using 2 GPU, all is fine.
After adding the third one, the ethernet is not recognized anymore.
Do you have some ideas ?
- Should i install ubuntu 16.04 Desktop instead of server ? or maybe Windows ?
- Should i install some specific drivers for ethernet ?
- Should i try to modify some settings in bios ? which ones ?
Thanks for your help.
