The GT 1030 does not support nvenc, which is probably what you are trying to use.

Your GTX 1080 does support nvenc, just use that.

Physically remove the GT 1030. The overall performance of your system will be better, since as long as it is plugged in, the pci-express bandwidth is divided between them and the 1080 isn't being operated at full speed. Even if you don't use the 1030 at all.

In this case i dont think that matters, his cpu has 28 pcie lanes.
