Question Samsung 970 PCle m.2 NVMe issue with an HP

[rghash]

Today what I’m told by the Samsung the MOBO will not support 3.0X4 now I have talked to Samsung several times in the last week & at no time have I been told that. Talking with HP last evening I finally got the person to ask the Tier 2 tech the question” if the MOBO would support 3.0X4 & they said yes”. The reason Samsung tech today told me that is in the Samsung Magician program the interface shows PCle Gen. 2 X 4

Now this was a comment (Below) I got back from a forum that would I say disputes what I got today from the Tech at Samsung.

“Your PC actually supports both Sata 3 or PCle NVME drives as you can see from the specification page of a different model of your PC with the same Motherboard which comes with a 128GB PCle NVMe drive.”

Both the HP 590 & 690 use the exact same Mobo, both are identical except the HP 590 is only sold in Europe. Now do I have to take it to a shop to get it to work, why won’t HP tell me what the problem is? I can barely get any info out of them, they should know what this MB is capable of wouldn’t you think. Just an fyi, I have a 5yr old ASUS MB and the manual for the MB has every detail about that Board, It guides me A to Z with words & pictures etc to get that board up and running.

This Link shows the 590 with a 128GB Pcle NVMe M.2 SSD https://support.hp.com/si-en/document/c06010496
The 590 comes with a 128 GB PCIe NVMe M.2 Solid State Drive Size: 128 GB Interface: M.2 Type: Solid State

So should I just factory reset the Samsung M.2 & reload Win 10? I have a disc I made for my old PC just before the deadline and it doesn’t have any serial # on it that I know of. If I can find the MS Win10 number on my HP I could make a copy for my flash drive to reload. Just so I can see if I can get the Samsung to work correctly like 3.0X4 as it should.

When I installed the Samsung 970 NVMe I also downloaded all the Drivers & the Samsung Magician tool. Using the Magician tool to do benchmark test says the Interface is PCle Gen. 2 X 4 and when I test the performance benchmark my performance is Write & Read speeds just over 1600 when I should be around 3000. The tool also tells me the Interface is PCle Gen 2 X 4

It looks like HP is providing four PCIe 2.0 lanes to the M.2 socket. This is why the NVME SSD will not perform at the optimal speed.
I was told that HP would have to fix this. I don't understand why HP is using PCle Gen 2 on a mainboard that supports PCle 3.0.

How could this be fixed or would I have any success in getting them to fix it. As I stated above they do sell the HP590 PC in Europe using the exact same motherboard with a Pcle NVMe M.2 SSD. Anyone have any idea what approach I could use with them to get this corrected.
