[Surachate]

I use this model (AIO HP pavillion 22-c0030d), after install m2 samsung evo 970 250GB, disconnect hdd 1TB and install windows 10 64 bit then check speed. I found samsung software report inferface m2. Gen 3 x 2 but it half speed of my drive. 

I would like to know this motherboard (turscany-R) support m2 gen 3 x 2 or 3 x 4. If have some function for set in bios, please let me know.

Greetings,

Welcome to the forum.

I am not a HP employee.

You are not the first person to report this in the Forum.

It appears HP is only supporting PCIe 3.0X2 speeds in the M.2 socket on your MB. It is doubtful you will find a BIOS setting to enable M.2 PCIe 3.0x4 speed on your MB.

Only two HSIO lanes are connected to this socket from the chipset. x4 speeds require four HSIO lanes.
