ASRock B550M-HDV AM4 Motherboard Overview

The ASRock B550M-HDV delivers reliable performance for AMD Ryzen builds in a compact Micro-ATX form factor. Built on the AMD B550 chipset, this motherboard supports 3rd Gen AMD Ryzen processors and future AM4 CPUs, making it a solid foundation for budget-conscious PC builders.

Power Delivery and Performance

Equipped with a 6-phase power design and premium 50A power chokes, the B550M-HDV provides stable power delivery to your CPU. The enhanced power components offer three times better saturation current compared to traditional chokes, ensuring consistent Vcore voltage for reliable system operation and moderate overclocking capabilities.

Memory and Expansion

Two DDR4 DIMM slots support up to 64GB of memory with speeds reaching DDR4 4733+ (OC) when paired with compatible Ryzen APUs. The board features dual-channel memory technology with 15µ gold contacts in DIMM slots for improved connectivity. For expansion, you get one PCIe 4.0 x16 slot (with Matisse CPUs) or PCIe 3.0 x16 (with APUs), plus one PCIe 3.0 x1 slot.

Storage Capabilities

The Hyper M.2 socket supports PCIe Gen4 x4 M.2 SSDs, delivering twice the speed of PCIe Gen3 drives when used with compatible processors. Four SATA3 6.0 Gb/s connectors provide additional storage options with RAID 0, 1, and 10 support, along with NCQ, AHCI, and hot plug functionality.

Graphics and Display Outputs

Three display outputs accommodate various monitor configurations: HDMI 2.1 supporting 4K@60Hz with HDR and HDCP 2.3, DVI-D, and D-Sub ports. Triple monitor support is available when using Ryzen APUs with integrated Radeon Vega graphics. The HDMI port supports Auto Lip Sync, Deep Color, and High Bit Rate Audio for enhanced multimedia experiences.

Connectivity Features

Rear I/O includes six USB 3.2 Gen1 ports (four rear, two via front header) and two USB 2.0 ports, all with ESD protection. Gigabit Ethernet powered by Realtek RTL8111H provides reliable network connectivity with Wake-On-LAN, Energy Efficient Ethernet 802.3az, and lightning/ESD protection. Realtek ALC887 audio codec delivers 7.1 channel HD audio with surge protection.
