I never said it was. Your SSD is capable of x4. Its exactly the type of SSD I have on my own laptop. On mine it runs at x4 speed but on some models the M.2 slot will not go to x4. The consensus here is that somehow yours and other HP models are in that boat. HP does not share with us the details of how they design. HP sells it with specific hardware and they do not make any promises as to what happens when you try to upgrade to hardware they do not sell. This is a risk of upgrading that those of us who do it a lot fully understand but not everyone does. You can try setting the BIOS to default settings, you can try upgrading the BIOS; you can see if there is not a firmware upgrade for the SSD itself, try installing the specific Samsung NVME driver, but I doubt any of that does any good. Still worth trying I just do not want to get your hopes up.

For some reason it is running in x2 mode; only using 2 pcie lanes instead of 4. The Service Manual does not specify whether the NVME port is x2 or x4; your diagnostics seems to suggest it is an x4 port but device running x2. But it does say PCIe/NVME M.2speed max is 2150. 

 

Manual 

 

You are not the first to report this phenomenon on an HP laptop. But I have never seen a resolution.

Yes I am sure you do but I do not have it and neither has anyone else when the issue comes up. It has been suggested that the motherboard has been designed so that the PCIe/NVME slot is just 2x not 4x or capped at 2x somehow. I will say that 1750 speed is very good in the grand scheme of things.

You understand, do you not, I do not work for HP. I sure as heck do not need my ethics questioned. You paid money "for 3500 speed" to whoever sold you the SSD not me and not HP. Good day and good luck.
