[SOLVED] M2 PCIe 3.0 x4 support X570 MOBO

[azza_01]

Hi ,

Im planning to buy the MSI MPG X570 GAMING PLUS mobo . I will also use the ryzen 3600 cpu with it and a Samsung 970 EVO NVMe SSD 500GB . But my concern is i noticed on the msi website in its combability section its says nothing about supporting ryzen 3rd gen cpus with M2 PCIe 3.0 x4 storage . Only PCI 4.0. Im pretty confident it still work but im wanting to be certain. Ive attached a LINK to the mobo website combability. https://www.msi.com/Motherboard/MPG-X570-GAMING-PLUS/Specification

Does anyone know or have this mobo with the same kinda setup ?

it looks like my pc.
cpu 3600 xt
mb Gigabyte X570
SSD - 970 Evo plus

if its anything like mine it supports 3 & 4 on the sockets
they are backwards compatible. you can use PCIE 2 in them if you wanted to.

Like PCIe 3.0, PCIe 4.0 is forward and backward compatible. This means that PCIe 4.0 can be used as a direct replacement for PCIe 3.0, but it also means that if you connect a PCIe 3.0 card to the PCIe 4.0 slot, the card will perform to the PCIe 3.0 specs.

page 30 diagram just shows max speed per socket and per cpu - https://download.msi.com/archive/mnu_exe/mb/E7C37v2.2.pdf

Ah okay thats is good to know acutally . that manual with page 30 does seem as though its saying in the table PCIe 3.0 x4 under 3rd gen ryzen .

thanks for your feedback .

Storage
2x M.2 slots (Key M)

• M2_1 slot(from AMD® Processor)
  • Supports PCIe 4.0 x4 (3rd Gen AMD Ryzen™)
  • Supports PCIe 3.0 x4 (2nd Gen AMD Ryzen™/ Ryzen™ 4000 G-Series, Ryzen™ with Radeon™ Vega Graphics and 2nd Gen AMD Ryzen™ with Radeon™ Graphics)
  • Supports 2242/ 2260/ 2280/ 22110 storage devices
• M2_2 slot (from AMD® X570 Chipset)
  - Supports PCIe 3.0 x4 (2nd Gen AMD Ryzen™/ Ryzen™ 4000 G-Series,Ryzen™ with Radeon™ Vega Graphics and 2nd Gen AMD Ryzen™ with Radeon™ Graphics) and SATA 6Gb/s supports 2242/ 2260/ 2280 storage devices

its odd to me it doesn't mention Ryzen 3 on the 2nd socket.
I expect it works on it.
My MB has 2 PCIe 4.0 sockets so it was why I double checked yours.

Since it supports PCIe 4.0 on 3rd Gen ryzen on the top slot, it means it automatically supports gen 3 as it is backwards compatible.

it seems 10 months ago the listing said
2x M.2 slots (Key M)

• M2_1 slot(from AMD® Processor)
  • Supports PCIe 4.0 x4 (3rd Gen AMD Ryzen™)
  • Supports PCIe 3.0 x4 (2nd Gen AMD Ryzen™/ Ryzen™ with Radeon™ Vega Graphics and 2nd Gen AMD Ryzen™ with Radeon™ Graphics)

  • Supports PCIe 3.0 x4 and SATA 6Gb/s
  • Supports 2242/ 2260/ 2280 storage devices

which is less specific than it is now. (link to source)

I can't find anything specific, I expect its is okay as if it works for newer and older, it would be unlikely that it doesn't work for your CPU. It may only be PCIe 3 though. I would ask MSI Forums as they are likely to know the truth. I just can't find it in a search - https://forum-en.msi.com/index.php?forums/gaming-motherboards.122/
