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.

The second M.2 slot for the Aorus Elite seems to support PCIE3.0x2 instead of x4 stated in the review unless I read wrong. Could anyone else confirm? This is the swaying factor for me to lean towards the Mortar. Specs from Gigabyte website below:Storage Interface
1 x M.2 connector (M2A_CPU), integrated in the CPU, supporting Socket 3, M key, type 2242/2260/2280/22110 SSDs:
3rd Generation AMD Ryzen™ processors support SATA and PCIe 4.0 x4/x2 SSDs
3rd Generation AMD Ryzen™ with Radeon™ Graphics processors support SATA and PCIe 3.0 x4/x2 SSDs
1 x M.2 connector (M2B_SB), integrated in the Chipset, supporting Socket 3, M key, type 2242/2260/2280 SSDs:
Supporting SATA and PCIe 3.0 x2 SSDs

Almost all of the boards include PS/2 connector. Why they put it in 2020? They stopped making PS/2 devices 15 years ago. Better would be to have an empty space there.Ethos Evoss - Sunday, July 5, 2020 - link

"One of the main complaints about the AMD X570 motherboard line was the wide variation in pricing."This can't be said of Intel based motherboards? Yes it can and accurately so. What is the point with this pointless statement?

Does the WiFi module connect to any WiFi Network, or is it only ASUS Networks if so would I need to buy a WiFi adapter?CamoGeko - Sunday, August 30, 2020 - link
Hey, so is there any cheaper alternative to the Aorus 550M Pro with similar or better feature set? I'm in the middle of building a Ryzen system with 3300X and motherboard is the last thing I need to decide on. Other mATX at the same price or cheaper just don't look as good as the B550M Aorus Pro.Iqbalusamah - Sunday, October 25, 2020 - link
I need help..the mob manual says the m.2 slot for the chipset suport sata n pcie 3.0x2..but this review says it suport pci3.0x4..i bought a samsung 970 evo with a pcie 3.0x4..can it be used in the slotIqbalusamah - Sunday, October 25, 2020 - link
Help me..i cant understand which one is true..the 2nd m.2 slot for chipset runs at pci3.0x4 or pcie 3.0x2(mob manual).and can a pcie3.0x4 be used in the slotZwirley - Sunday, July 18, 2021 - link
Question, is this board capable of overclocking and does it have a good power phase design? I was wondering because I want to build an all-white system but then came across another concern of this motherboard and that is if this supports BIOS Flashback feature so that I don't have to go out of my way to purchase an older gen CPU for it to support my 5900xcharlesa365 - Tuesday, August 3, 2021 - link
My personal computer running Debian has had four GIGABYTE B550 Vision D motherboards. The first and fourth had NIC initialisation on power up problems. The second one's NICs died after ~6 months. The third did not show voltage/temperature values properly. GIGABYTE warranty agents wrote "We do not give support to Debian OS".
