M.2 SSD PCIe Gen4 lane operates at double speed rather than four lanes.
M.2 SSD PCIe Gen4 lane operates at double speed rather than four lanes.
I recently purchased a Kingston Fury Renegade 500GB M.2 SSD and immediately checked it with Crystal Disk Info and Mark. The read/write speeds were lower than expected. I noticed the M.2 drive was using x2, which is correct. I installed the AMD drivers, entered BIOS but didn’t find any settings for the M.2 slots. My system specs are listed in the photos—could you guide me on how to switch this to x4?
Have you refreshed your BIOS? I noticed in an older update for your motherboard it mentions "improved NVME device compatibility" (https://www.msi.com/Motherboard/MPG-X570...US/support). Also, your drive isn’t listed in the compatible drives, though it’s difficult to say if that’s the reason. (https://www.msi.com/Motherboard/MPG-X570...upport#hdd)
It's difficult to pinpoint the problem since anything outside their compatibility list isn't assured to function, though I can't confirm this without personal experience. I understand that my motherboard doesn't recognize my RAM as compatible, but adjusting the speed manually resolves the issue. (Sorry, not very helpful)
