NVMe SSD compatibility with motherboard

[dcristi05]

Hello!

I am looking currently to upgrade from my old HDD to an SSD(And preferably an NVMe M.2 gen 3 x4 SSD for better speeds). I was looking at the Samsung 970 EVO Series 250GB PCI Express x4 M.2 2280.

However, I am not quite sure if it will work on my motherboard. I've bought it only a year ago. It's an ASRock A320M-HDV. And I have 2 questions whether my motherboard will support the 970 evo or not:
1) My motherboard only has 1 PCI express 3 x16 slot and 1 x PCI Express 2.0 x1 Slot. Does it require a physical PCIe 2 x4 slot? Or is the NVMe slot enough?
2) The SSD does not appear in the supported list on the mobo manufacturer website. Is this a guaranteed thing that it will not be viewed by the system? Or is it a buy at your own risk (Might or might not work)

Given that the motherboard launched with Ryzen, not even 2 years ago, it would be pretty sheepy for me to have to upgrade the motherboard again. (Given that most TLC SSD's are not on the support list)

https://www.asrock.com/MB/AMD/A320M-HDV/index.asp#Specification
1 x Ultra M.2 Socket, supports M Key type 2242/2260/2280 M.2 SATA3 6.0 Gb/s module and M.2 PCI Express module up to Gen3 x4 (32 Gb/s) (with Summit Ridge, Raven Ridge and Pinnacle Ridge) or Gen3 x2 (16 Gb/s) (with A-Series APU, and Athlon 2xxGE series APU)*

The NVMe port on the motherboard is what you want.
The 970 isn't on the list, because that came out after the board did, and they just didn't update the list. Like they won't for a theoretical "980 EVO"

Please be aware tho, for OS and game loads the 970 evo won’t be appreciably faster than an 860 evo sata3. NVMe looks good on paper but unless you have an app that specifically uses it, theres a low ROI. I learned the hard way.
