Hello!
I'm playing with an Asus strix b250 with 2x PCIe 16x and 4x PCIe 1x. I have put 2x nvidia GPU directly on the 16x ports and one GPU on a 1x with a riser.
The panel detects all 3 GPU but when I set the device ID as 3 on the transcoding parameter it doesn't work.
If I unplug a GPU from a 16x port and I set the device ID as 2 it works. So the problem is not related to the riser.
Anyone managed to make 3 GPU work?
