ASROCK B550M-HDV DDR4 AMD Motherboard

The ASRock B550M-HDV is a Micro ATX motherboard built on the AMD B550 chipset, designed for the AM4 socket and compatible with 3rd Generation AMD Ryzen processors (Matisse). It delivers a practical, feature-rich platform for home, office, and entry-level builds without sacrificing modern connectivity standards. At its core, the board uses a 6-phase power delivery design supported by ASRock Super Alloy components — including a Premium 50A Power Choke, High Density Glass Fabric PCB, and Sapphire Black PCB — to ensure stable and consistent power to the CPU. The board accommodates up to 64 GB of DDR4 memory across two DIMM slots in dual-channel configuration, supporting speeds up to DDR4 4600 (OC) with Matisse-class Ryzen CPUs and up to DDR4 4733 (OC) with compatible APUs. Extreme Memory Profile (XMP) is supported, and the DIMM slots feature 15μ gold contacts for reliable long-term connectivity. Storage options are well-rounded: four SATA3 6.0 Gb/s connectors support RAID 0, 1, and 10 configurations, while the single Hyper M.2 slot accepts both SATA3 and PCIe modules — reaching up to PCIe Gen4 x4 (64 Gb/s) when paired with a Matisse processor, or Gen3 x4 (32 Gb/s) with APUs. NVMe boot support is included. For discrete graphics, the primary PCIe slot operates at PCIe 4.0 x16 with Matisse CPUs or PCIe 3.0 x16 with APUs. An additional PCIe 3.0 x1 slot is also available. Integrated graphics from Ryzen APUs can drive up to three displays simultaneously via D-Sub (up to 1920×1200 @ 60 Hz), DVI-D (up to 1920×1200 @ 60 Hz), and HDMI 2.1 (up to 4096×2160 @ 60 Hz with HDR and HDCP 2.3 support). Audio is handled by a Realtek ALC887 codec delivering 7.1-channel HD audio with surge protection. Networking uses a Realtek RTL8111H Gigabit LAN controller (10/100/1000 Mb/s) with Wake- LAN, Energy Efficient Ethernet 802.3az, and PXE support. ASRock Full Spike Protection covers all USB, audio, and LAN ports. Connectivity includes 6 USB 3.2 Gen1 ports (4 rear, 2 via front header), 4 USB 2.0 ports (2 rear, 4 via headers), and a PS/2 keyboard/mouse port on the rear panel. The BIOS is a 256 Mb AMI UEFI with full GUI, Instant Flash support, and jumperfree operation.
