Re: Can't get 5 GPUs working, only 4. (Asus z170 Pro Gaming Aura)
Change PCIE x4 slot to x2 in BIOS setting.. I guess it might work.
I'm on BIOS:
Advance Tab / System Agent (SA) Configuration/ DMI OPI Configuration.
But DMI option is Greyed out.
How can I change from x4 slot to x2 in BIOS?
Please check in Advanced--> Onboard Device Configuration--> PCIEX16_ slot Bandwidth.. and see if x4 mode, x2 mode and auto are in options.
if its present.. put that in x2 mode and see if 5th gpu works..
