MSI B550M Pro-VDH Wifi DDR4 AMD Motherboard

The MSI B550M Pro-VDH WiFi is a Micro-ATX motherboard built on the AMD B550 chipset, designed for AMD AM4 socket processors. It supports AMD Ryzen 5000 series and Ryzen 3000 series desktop processors (excluding Ryzen 5 3400G and Ryzen 3 3200G), as well as AMD Ryzen 4000 G-Series desktop processors. A BIOS update may be required to enable support for the latest generation Ryzen processors. The board features four DDR4 memory slots supporting up to 128 GB of unbuffered (non-ECC and ECC UDIMM) memory in a dual-channel configuration. JEDEC speeds up to DDR4-3200 are supported natively, while A-XMP overclocking profiles can push speeds up to 4400 MHz (1DPC 1R). Storage options include four SATA 6 Gb/s ports and two M.2 slots (Key M). The primary M.2 slot (M2_1, from the AMD processor) supports PCIe 4.0/3.0 x4 and SATA, accommodating 2242, 2260, and 2280 form factors, and is protected by an M.2 Shield Frozr thermal solution. The secondary M.2 slot (M2_2, from the AMD B550 chipset) supports PCIe 3.0 x4 for the same drive form factors. Expansion is handled by one PCIe 4.0/3.0 x16 slot and two PCIe 3.0 x1 slots. Onboard graphics output includes VGA, DisplayPort (up to 4096×2160 @ 60 Hz), and HDMI (up to 4096×2160 @ 24 Hz), available when using a processor with integrated graphics. Connectivity includes integrated 802.11 Wi-Fi with antenna connectors on the rear panel, a Realtek 8111HN Gigabit LAN controller, and Realtek ALC892 7.1-channel HD audio. USB ports total multiple USB 3.2 Gen 1 5 Gbps Type-A ports on the rear panel plus internal headers, and multiple USB 2.0 ports. RGB customisation is supported through two 4-pin RGB LED connectors and two 3-pin RAINBOW LED connectors. The board ships in a standard Micro-ATX form factor measuring 9.6 in. × 9.6 in. (24.4 cm × 24.4 cm) with eight mounting holes, and MSI backs it with a 3-year warranty. Verified Specifications: – Form Factor: Micro-ATX, 9.6 in. × 9.6 in.
