Hello, I currently have an Asus ROG Maximus VIII Extreme (z170) motherboard. The board has 1 m.2 nvme ssd slot and a u.2 slot. Is it possible to use two m.2 nvme ssds? with a pcie or u.2 adapter or any adapter for that matter without issues? The only thing currently occupying a PCIE slot is my 1080 ti.
U2 is disabled when you install an NVME M2 drive.
You can install a 2nd NVME in a PCIE slot adapter. If you use the chipset x16 slot (bottom grey one I believe) then you won't drop your CPU down to x8 mode.
