Hello,

my Samsung SM951 NVME SSD, which is connected at the M.2 Slot, cannot use it's full potential of about 2000 MB/s reading and 1200 MB/s writing speed.

Instead it performs at around 1500 (reading) and 600 (writing).

So it looks like it only uses two lanes.

I would like to use the full 4 lanes.

Where in the UEFI settings can I change this? The mainboard is supposed to support M.2 with Gen3 x4.

I am using the latest official UEFI Version (1.6). CPU: core i3 6100. Win10 Pro.

Looking forward to the reply.

I would just poor over the settings in storage configurations in bios.

Maybe there is a setting to change pcie to gen 3 as opposed to gen 2 somewhere also.

Hi,

I just found out that I am actually close to the full potential of the SSD, because I am using the 128 GB Version which is reading 2000 MB/s and writing 650 MB/s max.

I'm basically ok with this and do not need any help anymore. Thanks!
