I am attempting to mount my GPU vertically on the X570-F Motherboard but it is causing reboots less than a minute into loading windows. I heard that setting the motherboard to use PCIE 3.0 instead of PCIE 4.0 fixes any issues with a riser cable, but I can't find that anywhere in the BIOS. Is this something that will be added to the X570-F BIOS in the future? Or does anyone know of a PCIE 4.0 compatible riser cable?

Thanks in advance
