Question Question about compatibility with PCIe Gen 4 on a PCIe Gen 3 x 4 motherboard.

[Henryy1]

Can i install a pcie 4.0 m.2 ssd with my current setup?
My mobo is a Gigabyte A320M S2H v2, it has PCIe Gen 3x 4. My processor is a Ryzen 5 3400g which i think its second gen.
Im confused because a bios update removed pcie 4 support for gen 3 Ryzen, but it dont know if i ever had pcie 4 support with my processor or if the drive will work, but at PCIe 3 speeds.

What specific BIOS update removed that?

Generally, drives are forward and backward compatible.

PCIe 4.0 support was removed for 3rd gen Ryzen on bios version F42. Im on F57d rn.

Then it would seem to be that no, you can't use a 4.0 drive with that board and CPU.


BUT......is that for the PCIe slots (where you put a GPU) or the M.2 port, where you put a storage device?
I's want confitmation from the manufacturer either way.

The changelog for F42 just states PCIe 4 support is removed, so it may just say that for the GPU slot. i already bought the drive thinking it would work because pci 4 is backwards compatible with 3. I will try it when it arrives.
I sent a support question to gigabyte asking if its for the pcie slots or both the m.2 and pcie.
