With 4× DDR4 DIMM slots, the B550M PRO-VDH supports up to 128GB of memory in dual-channel mode, making it suitable for gaming, multitasking, and productivity workloads. Memory overclocking support depends on CPU and RAM compatibility.

Storage & Connectivity

Dual M.2 + SATA Expansion

• M2_1: PCIe 4.0 x4 (CPU dependent)
• M2_2: PCIe 3.0 x4
• 4× SATA 6Gb/s for HDDs and SATA SSDs

Enjoy fast boot times and game loading speeds with NVMe drives while keeping extra storage via SATA ports.

Rear I/O Connectivity

• 1× HDMI
• 1× DVI-D
• 1× VGA (D-Sub)
• USB 3.2 Gen 1 ports
• USB 2.0 ports
• Realtek Gigabit LAN (RJ-45)
• Audio jacks

Cooling & Build Features

• Heatsinks on VRM & chipset for stable thermal performance
• Fan headers with smart control for efficient cooling setup
• EZ Debug LED to help identify CPU, RAM, VGA or boot issues quickly

Compatibility Notes 

1) AM4 CPU Required

This motherboard supports AMD AM4 processors only. It is not compatible with AM5 CPUs.

2) Display Ports Require an APU

HDMI, DVI and VGA outputs work only if you use a Ryzen CPU with integrated graphics (e.g. Ryzen “G” series). If using a standard Ryzen CPU without iGPU, a dedicated graphics card is required.

3) PCIe 4.0 CPU Requirement

PCIe 4.0 support depends on installing a compatible Ryzen 3000 or 5000 processor. Older CPUs may operate at PCIe 3.0 speeds.

Ideal For

• Budget and mid-range AMD gaming PCs
• Office and productivity builds
• Compact Micro-ATX cases
• Upgrading existing AM4 systems

The MSI B550M PRO-VDH delivers reliable AMD AM4 performance with PCIe 4.0 support, dual M.2 NVMe storage, 128GB DDR4 capacity, and solid connectivity — making it a strong value choice for Ryzen-based Micro-ATX builds.
