I recently bought a 990 pro ssd, but it's not showing up in my mobo's (see title) bios at all. All of my m.2 ports are working with my older m.2 ssd, and i hooked up the 990 pro to an acer predator helios laptop to test and it works absolutely fine. I've got the right settings in my bios as far as i know and it's fully up to date, and pcie 4.0 hardware should be compatible with a pcie 3.0 port so I don't understand why I can't use it.
my cpu is an i7-9700k if that matters.
