Question 970 Evo Plus Running Slow on X570 (2600X)

[Ruicko]

So I recently bought a Samsung 970 Evo plus 1Tb and installed it into my setup (B450 with 2600X) and it ran pretty bad (1300Mb/s read, 1150 write)

I then decided to make the leap to X570 considering I was already a bit behind. The drive now runs at 1800Mb/s read and 1770 write although this is basically half the rated speed.

I'm aware my motherboard only allows PCIE 3.0 due to my 2nd gen Ryzen CPU however seeing the diagram in this article I'm stumped (https://www.fullexposure.photography/how-fast-is-pcie-4-0-nvme-vs-pcie-3-0/ ). Should I be getting 3.5Gb/s read? Or am I destined to suffer below average speeds to my end?

Thanks for any help in advance!

Edit: Oh yeah btw I have an MSI X570 MPG Gaming Plus. Yes I've checked the manual/specs

I'll simplify: are you using the topmost M.2 socket?

Yes I am - M2_1

Then yes, a 1TB 970 EVO Plus should be scoring higher than that. You didn't specify how you were checking the performance, though. I would recommend various tools to verify: CrystalDiskMark, AS SSD, ATTO, etc.

I used samsung magician and CDM, both gave 1.8gb/s read 1.7ish write

Does CrystalDiskInfo indicate x4 PCIe lanes and not x2?

Does CrystalDiskInfo indicate x4 PCIe lanes and not x2?

It says PCIe 3.0 x2 (current mode) and PCIe 3.0 x4 (supported mode)

So my issue seems to be that I'm only utilising 2 PCIe lanes rather than 4? I know this mobo has 4!

That would explain the half performance you have.

What is your motherboard?

Just updated my bios, getting 3.5Gb/s read, 3.25 write wasted ur guys' time a bit there haha sorry

Glad you got it sorted.
