Hi everyone, I ran into an issue where my Samsung 970 Evo 1TB M.2 NVME is only using x2 PCIe lanes instead of the x4 it supports. As such I am only getting half the rated speed.
Motherboard: Asus RoG Strix 370-e
CPU: i7-8700k
GPU: Nvidia 2080FE
RAM: G.skill TridentZ 4x8GB
Additional Storage: Samsung 860 2.5" Sata SSD 250GB (Boot Drive to be hopefully replaced), Samsung 860 M.2 Sata SSD 1TB, WD Green HDD 1TB
I can't switch the M.2s around because only one port supports SATA.
From my understanding and feel free to correct me, my chipset should support up to x24 PCIe lanes. My GPU uses x16, I have nothing else connected to the motherboard, and the other storage drives' interfaces are SATA which don't use PCIe lanes. I'm not sure if my NVME is defective or not. My only other option at this point to figure it out is to disconnect my GPU and connect my display to the motherboard to definitively free up lanes and see if that is the issue. Any other ideas as to what the problem is and how to fix it?
