Hi,

Im having some trouble with bios settings on my motherboard. I have the last version now and while NVME is working and my gpu also working i cant seem to put my gpu working at pci-e 3.0 x16 like before i bought the M2 NVME disk.

It shows PCI-E x4 3.0 in gpuz in full gaming experience. In BIOS i tried everything i could think of in AMD PBS settings and no luck until i reverted to defaults.

Is my NVME stealing lanes from the main gpu?

Main gpu is an RX 580 4GB!!!

My motherboard is ASRock B450 Pro4-F and the NVME disk is a Kingston KC2000 250GB

TIA
