ROG STRIX B560-G stuck in PCIE 3.0 mode

Shannou
Level 7

All of a sudden error sprung in BIOS - The PCIE x16 link speed has been modified to Gen 3, nothing helps so far to return the videocard to Gen4 mode, not possible to select in UEFI, Gen1-3 and Auto are only selectables.  

Guy here has similar error. https://linustechtips.com/topic/1494891-pcie-lane-speeds-changed-to-gen3-how-do-i-change-it-back/

My Config:

MB: ROG STRIX B560-G, BIOS v.1601, Proc. 11400F, VC: Asus RTX2060, GF driver version 531.41, Windows 11 22H2, latest patches.

Thank you in advance for possible solutions.

Hello, @Shannou .

May I ask if the graphics card you are using is the DUAL-RTX2060-O6G-EVO?

Thank you.

Thank you, my bad, still strange to receive this message on switching to Gen3 year after building up a rig if I was already on Gen3 from the beginning.
