Question: Mac Pro 5.1 PCIe Link Width
I just bought an x16 Asus nvme controller and I dropped it in to a x16 slot and I only got x4 link width and 2.5GT speed. It will only read one of my 2 nvme drives but the point of the x16 card is that it's supposed to read all drives.
I tried changing slots with the video card and still don't work.
Can anyone help getting my X16 slot run at x16 speeds?
Mac Pro, macOS High Sierra (10.13.1)
