ASRock B550M-HDV AM4 Micro-ATX Motherboard - DDR4, PCIe 4.0
The ASRock B550M-HDV AM4 Micro-ATX Motherboard is designed for builders who want a compact, budget-conscious platform that supports AMD's full AM4 lineup through Ryzen 5000 Series. It solves the problem of fitting a capable, modern chipset into a small-form-factor build without sacrificing PCIe 4.0 storage or display output flexibility.
Why this product
Broad AMD Ryzen CPU compatibility
The AM4 socket supports Ryzen 3000, 3000 G-Series, 4000 G-Series, 5000, and 5000 G-Series desktop processors, covering several generations of AMD CPUs.
PCIe 4.0 M.2 storage slot included
The Hyper M.2 socket runs at up to Gen4x4 (64 Gb/s) when paired with Vermeer or Matisse processors, providing fast NVMe storage without an add-in card.
Three display outputs for iGPU builds
D-Sub, DVI-D, and HDMI ports are all present on the rear panel, with the HDMI port supporting 4K resolution. These outputs are active only with processors that include integrated graphics.
DDR4 overclocking headroom
Memory can be overclocked to 4733+ MHz with compatible APUs, and the board supports ECC and non-ECC unbuffered modules across both DIMM slots.
High Density Glass Fabric PCB
Reduced gaps between PCB layers help protect against electrical shorts caused by humidity, a durability measure ASRock applies across this board's construction.
AMD StoreMI tiered storage support
AMD StoreMI technology can combine an SSD and a hard disk into a single logical drive, automatically moving frequently accessed data to the faster storage.
- SocketAMD AM4

- LANGigabit (Realtek RTL8111H)
- SKUASR-2018
- EAN4710483931635
- Fits AMD AM4 socket CPUs: Ryzen 3000, 3000 G-Series, 4000 G-Series, 5000, and 5000 G-Series desktop processors.
- Fits standard Micro-ATX cases; the board uses the Micro-ATX form factor.
- Compatible with DDR4 unbuffered DIMM modules (ECC and non-ECC) in standard DIMM form factor across 2 slots.
- The M.2 slot runs at PCIe Gen4x4 only with Vermeer and Matisse CPUs; it falls back to Gen3x4 with Cezanne, Renoir, and Picasso processors.
- The D-Sub, DVI-D, and HDMI display outputs are functional only when using a processor with integrated graphics.
- Not compatible with AMD AM3, AM3+, FM1, FM2, or FM2+ processors — AM4 only.
Best for
- Compact desktop builders who need Micro-ATX dimensions with a modern AMD chipset and PCIe 4.0 support.
- APU / iGPU builds where three simultaneous display outputs (D-Sub, DVI-D, HDMI) are needed without a discrete GPU.
- Budget-focused system builders who want B550 chipset features — including PCIe 4.0 M.2 and RAID support — without higher-end board pricing.
- Upgraders staying on AM4 who plan to drop in a Ryzen 5000 Series CPU now or later, given the broad CPU generation support.
- Builders using AMD StoreMI who want automatic tiering between an SSD and a hard disk on a single logical volume.
Trade-offs
- Enthusiast overclockers who need more than 2 DIMM slots or more than 64 GB of total memory capacity.
- Multi-GPU or high-expansion builds: only one PCIe x16 slot and one PCIe 3.0 x1 slot are available, with no additional PCIe slots.
- Builders needing multiple M.2 slots: only one M.2 socket is present on this board.
- Users requiring USB 3.2 Gen2 or faster rear ports: rear USB is limited to four USB 3.2 Gen1 ports and two USB 2.0 ports.
- ATX or E-ATX case builds: the Micro-ATX form factor will not fill larger motherboard trays as intended.
AMD AM4 socket supports Ryzen 3000, 3000 G-Series, 4000 G-Series, 5000 and 5000 G-Series processors. 6 power phase design, DDR4 up to 4733+ MHz overclocked, 1 PCIe 4.0 x16, 1 PCIe 3.0 x1.
Supports the most recent HDMI 4K 60Hz graphics output specification. With the larger bandwidth and increased frame rate, the motion on your screen becomes more fluid and less blurry.
A powerful tool that combines the speed of your SSD with the capacity of your hard disk into a single, fast, easy-to-manage drive, AMD StoreMI technology "combines" these two types of storage into a single drive and automatically moves the data you access the most to the SSD, so you get the best of both worlds.
Compared to traditional chokes, ASRock's premium 50A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.
A new mysterious matte black and copper color scheme to match the prestigious components on ASRock's high-end motherboards.
High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.
Complete with all three types of most used connectors! Packed with a D-Sub + DVI-D + HDMI combo. Plus the HDMI port supports 4K resolution. *Supported only with processors with integrated graphics. Please check CPU support list from each motherboard webpage.
