The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Others
by Dr. Ian Cutress & Gavin Bonshor on June 16, 2020 11:00 AM ESTASRock B550M-HDV
Nearer the bottom of the ASRock product stack we get to the B550M-HDV, which is aimed at the more commercial pre-build markets and aims to offer what these markets might need. As a result it does away with the fancy styling and aims to give the bare essentials. That means no power delivery heatsinks, only two DRAM slots, no extra M.2, and only a 4-pin CPU power connector is needed.
The idea for these boards is that they will be put into systems that might be found in commercial units, like libraries, medical facilities, youth centers, that sort of thing. So there are only two fan headers around the socket for example. The power delivery is basic, we get a 4 phase design, and the two DRAM slots are still single side latched.
Moving clockwise around the board we get the 24-pin ATX power connector, a USB 3.0 header, and four SATA ports. The bottom of the board is the audio front panel header, a Clear CMOS header, a TPM header, a COM header, two USB 2.0 headers, another 4-pin fan header, and the front panel header.
The PCIe area consists of a single PCIe 4.0 x16 slot, without extra reinforcement. Beneath this is the PCIe 4.0 x4 M.2 slot from the processor, and underneath this is the chipset heatsink, which is the smallest chipset heatsink I’ve seen on B550 so far. On the left hand side of the board is the audio, where we have an updated ALC887 solution using PCB separation.
On the rear panel, we get two USB 2.0 ports, a combination PS/2 port, HDMI output, an analog D-sub video output, DVI-D, four USB 3.2 Gen 1 ports, a single gigabit Ethernet from a Realtek RTL8111H controller, and the audio jacks.

Right now, it seems more like B for Backordered. They may be priced a bit high, but the demand still seems to be there.yannigr2 - Tuesday, June 16, 2020 - link
This is a great article but it needs a follow up with a table for every motherboard explaining how they use the PCIe lanes in conjunction with M2 and SATA slots. It seems that motherboard makers are totally f up(sorry for the expression) the more reasonably priced models in that area.romrunning - Tuesday, June 16, 2020 - link
Does anyone know if the boards that have the Intel i225-V are shipping with the fixed hardware (v2)?R3MF - Tuesday, June 16, 2020 - link

Wow, another broken Intel NIC? I wish motherboards would stop using Intel NICs.mooninite - Tuesday, June 16, 2020 - link
After Googling it looks like v2 is not fixed either... a v3 is coming out. Time to buy Realtek.romrunning - Wednesday, June 17, 2020 - link
Which is hilarious - I remember when Realtek was the worst when it came to NICs, and Intel/3Com was the standard. :)WaltC - Wednesday, June 17, 2020 - link
Yes, indeed...;) My x570 Master has an Intel gigabit & a realtek 2.5gb. It's amusing because my interface is an EWAN that tops out at 1Gb, but I thought I'd try the realtek just to see and then I forgot about it...;)...Seems every bit as stable as the Intel--still on it, lol...;) Six of one, half-dozen of another.eastcoast_pete - Tuesday, June 16, 2020 - link
Thanks Ian and Gavin! One question, related to a likely use case for B550 mini ITX or mATX Boards: is it true that AMD will, at least initially, limit Ryzen 4000 APUs to OEMs? If that is so, I am definitely not interested in a B550 board in those form factors, and I don't think I am alone here. An answer is appreciated - thanks!mrvco - Tuesday, June 16, 2020 - link
I'm just here for the Next mini-ITX boards. I'm liking the Aorus Pro AX quite a bit.
