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.
