Hey any chance we can get a Zenith II Extreme bios update to support the 4090?
I am stuck with 4 machines that only run PCI x16 1.1 with the 4090 and tried everything else to fix this but seems you have not updated the bios. Running on latest bios. Are we going to get an update? These are expensive boards and seems like we have been abandoned.

Zenith II Extreme / TR 3970x / RTX 4090 TUF works fine at PCI-e 4.0 x16
However, I did have problems using a GPU riser, which would only run at PCI-e 3.0 x16, at 4.0 it kept dropping to x1.
Also, make sure you haven't set the PCI slots to PCI-e 1.0 or x1 in the bios.
Pics below are whilst running Furmark, not sure how you're checking, but the power saving features drop the PCI-e slots to x1 1.0 when not in use.

Thanks very much for the reply. Good to know it should work.
Tried a different x16 slot and that seems to work now.
I JUST WISH ASUS WOULD PUT MORE INFO IN BIOS UPDATES.
Surely in one bios update they could have said updated to xyz now includes 4090 support.
