HELP: Adding a AMD GPU for the first time to a RIG full of NVIDIA

[shuweee]

Folks,

hopefully, someone can provide some guidance here. Got a rig here full of 6x NVIDIA GPU. Bought a Nitro+ RX 570 8GB, tried installing it, no luck. WIN 10, can't detect it, can't see it in the device manager, never had AMD card on it before so even attempt to run DDU to make sure there's no AMD drivers, no luck. Tried to replace riser, cables and tested it with the NVIDIA card and confirmed not the riser issue. I even tried to put the RX on the NVIDIA riser which I know works and vice versa. Running out of ideas here, any suggestion is greatly appreciated.

First of all, which mobo are you using? Want to make sure that your mobo didn't need advance set up to recognize more GPU. Are you sure that your PSU has enough power?

Maybe you can try 5 NVIDIA plus one AMD. Hope this scheme can explain more why you can add one AMD on six NVIDIA.
