ROG STRIX Z790-F GAMING WiFi - PCIEX16 Slots

[goodtrips]

What do I need to do in order to use all three of my PCIEX16 slots (G5, G4_1, and G4_2)?  I am using slots G5 and G4_2.  According to AIDA64 Extreme slot G4_1 is unavailable.  I would like to use that slot for a second graphics card (dedicated to PhysX).  What BIOS settings do I need to change?

Hello goodtrips

I don't think it will work.

G4_1 and G4_2 support x4 mode only, Nvidia gpu's need x8 to function.

The card I want to use for PhysX is a GT 1030.  I believe that will work in an x4 slot.  Now if I can only activate the slot .

Thank you

The GT 1030 does show it's pcie 3.0 x4.

In the bios, try setting the G4_1 slot to Gen 3.
