MSI B550M PRO-VDH AM4 Micro-ATX DDR4 Motherboard

MSI designed the B550M PRO-VDH for builders who want a balanced AM4 platform in a Micro-ATX footprint without extra cost. It runs the AMD B550 chipset on a 2oz thickened copper PCB for heat dissipation and signal stability, backed by a Core Boost digital power design that delivers clean voltage to the CPU.

Key Highlights:

• Ryzen Processor Support: The AM4 socket accepts Ryzen 5000, 3000, and 4000 G-Series chips, with the note that Ryzen 5 3400G and Ryzen 3 3200G are not supported.
• DDR4 Up to 128GB: Four dual-channel DIMM slots run speeds reaching 4400 MT/s (OC), with DDR4 Boost isolating memory traces to improve signal stability.
• PCIe 4.0 x4 M.2 Slot: Connected directly to the CPU with an M.2 Shield FROZR heatsink to prevent thermal throttling and hold peak read/write speeds.
• Second M.2 Slot: Runs PCIe 3.0 x4 so you can operate two NVMe drives simultaneously, alongside four SATA 6Gb/s ports for extra storage.
• Advanced Cooling: 7W/mK thermal pads on the power stages, an additional pad for the chokes, and an extended CPU heatsink keep the board stable under sustained load.
• Realtek Gigabit Ethernet: An RTL8111HN controller delivers a steady 1-gigabit wired connection for downloads and streaming.
• 8-Channel Audio Boost: A Realtek ALC892/ALC897 codec with premium audio capacitors and isolated audio layers delivers clearer in-game and media sound.
• Triple Display Outputs: VGA, DisplayPort, and HDMI, active only with a CPU that has integrated graphics.
• PCIe 4.0 x16 Slot: Connected to the CPU with PCIe Steel Armor protecting the graphics card against bending and electromagnetic interference.
• Flash BIOS Button: Updates BIOS from a USB key in seconds without a CPU, memory, or graphics card installed, simplifying upgrades to newer processors.
