Question Compatibility SN770 and AB350 PRO4

[Madjunac]

Hello everyone!

recently bought sn770 for my MB. it is not recognized neither by bios, nor by Device Manager/Disk Management. former Patriot scorch 128 gb works great, and is now moved to m2_2 slot (this one is SATA). sn770 is now in m2_1 (which is PCIe). today was formatted in another (more modern PC) and a letter was assigned. which indicates that the device is not corrupted by any means. interesting fact: patriot isn't recognized by bios, either. it works nevertheless.
CPU is Ryzen 2700x, bios is 5.0
if I understood it well, the 5.9 version is the last one to support Pinnacle Ridge. I'm not sure if flashing would do any good?
so, any ideas would be much appreciated!
thanks in advance!

Welcome to the forums, newcomer!

If I were you(and if you read through most/all threads here) I'd update the BIOS to the latest before dropping in any memory, storage or device as an upgrade.

To also add, your motherboard can't take advantage of a PCIe4.0x4 drive. You could've looked at a Samsung 970 Evo Plus or a TeamGroup MP33.

interesting fact: patriot isn't recognized by bios, either.
M2_2 only supports STA based M.2 drives, so that is why your drive isn't showing up in BIOS.

IMHO, you went backwards with your upgrade path. I'd return the SSD to pick up something that's PCIe3.0x4, unless you can flash the BIOS using a latter CPU, since A.EG.E.S.A code 1.2.0.0 enabled support for all sorts of memory on the market and by doing so, allowed you to work with processors from 2000 series all the way up to the 5000 series.

On a side note, all other motherboard makers don't nullify prior processors as you move upwards, which is confusing for me reading ASRock's support page.
