When my PCIe x16 link speed for my GPU in the BIOs is set to either Auto or Gen 4, my Zotac 4080 Super doesn't work/boot up.

It freezes and crashes at the AsRock logo screen or sometimes the dash at the top left corner.

Switching to Gen 3 makes it work every time. Still unsure what the problem is, as it should work fine with 4.0. Does anyone have an insight here of what to do? Does anyone have the same problem?
