3rd gen Ryzen processors

At this point unless you live in a country were stock isn't moving you'd be one unlucky dude to not get a board that supported Ryzen 5000 out of the box if you are worried get a board with bios flashback a ton of B550 boards support it.

B550 chipset supports only PCI-e 3.0. Unless you are buying one of those special board which makes primary PCI-e slot x8 and runs M.2 using the remaining x8 lanes your only choice is X570.
Or you already bought mother board then there is no need buy a new board.

I think he is only concerned with the primary slot supporting gen 4 from his posting. He just also want's a second gen 3 m.2 is what I'm taking from what he is saying.

Looks like I misread his requirement. My bad.
He want 2 M.2, I read he want 2 PCI-e 4.0 M.2. B550 will met his requirement.

This thread contains a list of motherboards I am considering. So if you have any suggestions/inputs feel free to reply there.

And yes. Currently I want to have the primary support PCIe 4.0x4(for newer SSDs) and the secondary be 3.0(for any existing ones).
Dual M.2 slots is a requirement - I have one 500GB SSD already and want to get a larger 1/2TB one later on.
I even have an adapter which converts from PCIe 3.0 x16 to M.2 - which eats 8 lanes of my graphics card

If you want PCI-e 4.0 on 2nd M.2 then you need to buy X570 board. B550 board's 2nd M.2 is PCI-e 3.0. Only Matisse and Vermer CPU's support PCI-e 4.0 on X570 and B550 boards.
Get board with BIOS Flash without CPU feature.

if you are saving on a B*** board you probably aren't the type of buyer of two M.2 Pci4, probably not even one let alone 2. Seems like a made up problem

The #1 requirement is that there should be two or more M.2 slots(for expandability). If one of them is 4.0x4 then it's that much better performance (and longevity) wise.

My current Z97 board doesn't have enough PCIe lanes so the M.2 slot shares bandwidth with the last x16 slot, which is actually 2.0x2. That caps my 970 Evo Plus SSD to 1000 MB/s(~820 in practice).
I had to get an adapter and cut my graphics card bandwidth in half(Got 2 3.0x16 slots with SLI capability, now each is running x8) to get max performance out of that SSD.

Just in general, having the possibility to flash the bios without a CPU is a good thing to have when selecting a motherboard and being unsure that does it have a bios support out of the box.

Having to borrow a CPU or getting the board to a PC shop for a bios flash would just suck.

True, but how are you supposed to know which boards, or even which BIOS version a given board has before installing a CPU?
I am assuming the system would simply not POST if an incompatible CPU is installed(for the BIOS I mean).

That's practically impossible to know as AFAIK it's not mentioned in the box, so you practically just try your luck. Or if it has a sticker mentioning that it's ready for let's say Ryzen 5000 series.

In my case it was easy as I have a 3600 and B550 board. And as the chipset is newer than the CPU, it had initial support.

If you look at the board the bios chip sometimes has its version printed on a label attached to the chip.

I can state about my own msi b550 tomahawk it has 2 nvme slots, bios flash back. Good vrm’s, techspot liked it,. Not so many usb ports 6 or 8.
And the flash back works quite well. I have used it.
