Hi everyone,
I just built a PC with a MSI MPG Z790 EDGE WIFI DDR4 motherboard and I'm struggling to find the BIOS Gen setting for PCI_E3.
As per the manual:
2x PCIe x16 slots:
I installed my secondary GPU (NVIDIA T600 PCIe 3.0 x16) into PCI_E3 and I expect it to run at PCIe 3.0 x4 in the 4.0 x4 slot.
However, it gets assigned Gen1 and therefore runs at 1.0 x4.
I can only find a PCIe Generation setting in the BIOS for the PCI_E1 which is not what I need - as that slot behaves correctly with my main GPU (which is PCIe 4.0 x8).
I don't have any M2 drives installed, therefor didn't touch the settings for those. I can't find any piece of text in the docs that implies that any of those M2 Gen settings would affect the PCI_E3 Gen setting anyways.
Can I get some advice on this please?
Thank you.

As per the manual:

- PCI_E1 slot (From CPU)
Supports up to PCIe 5.0 x16 - PCI_E3 slot (From Z790 Chipset)
Supports up to PCIe 4.0 x4
