PCIE 4.0 on Asus Prime X370 Pro?

Hi,

A few Months ago I upgraded my 5 year old PC with an R7 5700X and a 6900XT. I know some UEFI revisions for 3000 series allowed for PCIE 4.0 on the Asus Prime X370 Pro and I was wondering if it was somehow possible to do that with a 5700X. According to GPU-Z my GPU is running at PCIE 3.0. I know the answer is most likely no but I was unable to even find the option in my UEFI for changing to PCIE 2.0. The option to change revisions at all simply seems missing or I am just blind. I tried both v6026 and v6042 but couldn't find the option.

 

Thanx

As far as I know, those BIOS versions only existed when the 3000 series was out (so wouldn't support 5000 series) and were only for 400 series boards. I don't believe the physical traces on 300 series boards are capable of running Gen 4.

Doubt it will run Gen 4 but according to the manual the option might be there?

The 6900XT uses a x16 slot with all the pins, so when running in a pci-e 3.0 x16 slot it's the same as having about pci-e 4.0 x8 and that's not a limitinig factor for the 6900XT.

The Asus Prime X370 Pro definitely supported it with 3000 series.

I know it wouldn't make much of a difference with an x16 card but I still wanted to try if possible. But I couldn't even find the option to take it down to 2.0.
