MSI B550M PRO-VDH AM4 M-ATX Motherboard

What this part is

<p><strong>AMD AM4 socket with B550 chipset | PCIe 4.0 M.2 storage with thermal shielding | Up to 128 GB DDR4 memory | Triple display output | Flash BIOS without a CPU installed</strong></p> <p>The MSI B550M PRO-VDH is a Micro-ATX motherboard built for system builders who want a reliable, feature-complete AMD platform without unnecessary complexity. Paired with the AMD B550 chipset and AM4 socket, it supports AMD Ryzen 5000, 4000 G-Series, and 3000 Series desktop processors (excluding Ryzen 5 3400G and Ryzen 3 3200G), giving you a broad range of CPU options for productivity and everyday computing builds. Four DDR4 memory slots accommodate up to 128 GB of RAM in dual-channel configuration, with support for speeds up to 4400 MHz via A-XMP OC mode for those who want to push performance further. Two M.2 slots — the first running PCIe 4.0 x4 from the processor, the second PCIe 3.0 x4 from the chipset — are complemented by M.2 Shield Frozr heatsinks that keep SSDs cool under sustained workloads, preventing thermal throttling. Four SATA 6 Gb/s ports, a PCIe 4.0/3.0 x16 slot, and a generous rear I/O panel including VGA, DisplayPort, and HDMI 2.1 outputs round out a well-equipped board ready for a compact, capable build.</p> <h3>Features</h3> <ul> <li>AMD AM4 socket supports Ryzen 5000, 4000 G-Series, and 3000 Series desktop processors</li> <li>PCIe 4.0 x4 M.2 slot (M2_1, from CPU) and PCIe 3.0 x4 M.2 slot (M2_2, from chipset) — both with M.2 Shield Frozr thermal coverage</li> <li>Four DDR4 slots supporting up to 128 GB, with speeds up to 4400 MHz (OC) in dual-channel</li> <li>Triple display output: VGA, DisplayPort, and HDMI 2.1 — each supporting up to 4K where the CPU's integrated graphics allow</li> <li>Core Boost and DDR4 Boost technologies with a 2 oz thickened copper PCB for improved power delivery and signal integrity</li> <li>Flash BIOS Button enables BIOS updates via USB without a CPU, memory, or graphics card installed</li> <li>Realtek ALC892/ALC897 7.1-channel HD audio codec for clear, detailed sound output</li> <li>Realtek 8111HN Gigabit LAN for stable 1 Gbps wired connectivity</li> </ul> <h3>Specifications</h3> <ul> <li>Socket: AM4</li> <li>Chipset: AMD B550</li> <li>Form Factor: Micro-ATX</li> <li>Memory Type: DDR4</li> <li>Memory Slots: 4</li> <li>Max Memory: 128GB</li> <li>M.2 Slots: 2</li> <li>PCIe Version: PCIe 4.0 / PCIe 3.0</li> <li>LAN Speed: 1 Gbps</li> <li>Rear USB Ports: 4x USB 3.2 Gen 1 5Gbps Type-A,2x USB 2.0 Type-A</li> <li>Colour: Black</li> <li>Product Dimensions: 24.4 x 24.4 cm</li> </ul> <h3>What's in the Box</h3> <ul> <li>MSI B550M PRO-VDH AM4 M-ATX Motherboard x1</li> <li>SATA Cables x2</li> <li>I/O Shield x1</li> <li>Quick Installation Guide x1</li> </ul>
