Newly installed NVMe disk limited speed

Goldien · Dec 21, 2023

Hi,
Yesterday I installed my new NVMe disk - Lexar 1TB M.2 PCIe Gen4 NVMe NM790. I tested it with CrystalDiskInfo and CrystalDiskMark, the first one shows that everything is fine with it, but the second one shows that the speed are limited by a half. I attach couple screenshots with the results. Can anyone tell me what's the reason it's happening? CrystalDiskInfo shows that the current mode is PCIe 3.0 x4 and supported mode is PCIe 4.0 x4, but I'm nearly certain that my MOBO has gen 4.0 slot. Should I change some things in the BIOS?
MOBO - MSI B560M-A PRO
CPU - Intel i3-10105F

Edit. forgot that Intel 10th gen does not support PCIe 4.0, my bad, solved :oops:

Yes that's the normal speeds you have, everything is working as it should. You could get higher speeds, but most of times you won't ever notice different speed when you boot windows up.
It's at least much faster then SATA at 600MB/s.
