MSI B550M PRO-VDH AM4 M-ATX Motherboard

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

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.
