Sorry Banditt1976, technically it does support PCIe 4 for the PCIe slots there is even a setting in the Bios for PCIe 4. It does not support it for the M.2 slot. But whatever the situation with PCIe 4 is, the PCIe slot should not be locked at x8 speed. Maybe this was something done with the Beta Bios which says it added support for the 11th Gen processors or something else, that is what I need to find out.
I suppose if no one else has this situation, I will have to go back to the 10th Gen processor, the benchmark showed it had higher scores..
What I don't want to do is purchase a new motherboard and then find out its performance is restricted in the same manner.
Thanks for the response..
