MSI B450M Pro-VDH Max DDR4 AMD Motherboard

The MSI B450M Pro-VDH Max is a Micro-ATX motherboard built on the AMD B450 chipset for Socket AM4 processors. It is compatible with 1st, 2nd, and 3rd Generation AMD Ryzen desktop processors, as well as Ryzen with Radeon Vega Graphics, 2nd Gen AMD Ryzen with Radeon Graphics, and Athlon with Radeon Vega Graphics APUs — making it a versatile foundation for a wide range of AMD-powered builds. Memory support is a strong point of this board. The four DDR4 DIMM slots accept up to 64 GB of system RAM and can run at JEDEC-rated speeds of 1866, 2133, 2400, and 2667 MHz. With A-XMP overclocking profiles enabled, Ryzen Gen 3 (R5/R7/R9) processors can push memory speeds up to 3866 MHz, while other AM4 processors support up to 3466 MHz OC. Dual-channel mode and ECC UDIMM (operating in non-ECC mode) are both supported. MSI's DDR4 Boost technology uses an isolated memory circuitry design to deliver clean data signals for improved stability. For storage, the board provides four SATA 6 Gb/s ports with support for RAID 0, RAID 1, and RAID 10 arrays. A single M.2 Key-M slot supports PCIe 3.0 x4 (for Ryzen and Ryzen with Vega/Radeon processors) or PCIe 3.0 x2 (for Athlon with Vega), as well as SATA 6 Gb/s, accommodating 2242, 2260, and 2280 form-factor drives. NVMe SSDs operating through the M.2 slot benefit from MSI's Turbo M.2 routing at PCIe Gen 3 x4 bandwidth. Expansion slots include one PCIe 3.0 x16 slot (running at x16 with Ryzen, x8 with Ryzen APUs, or x4 with Athlon APUs) and two PCIe 2.0 x1 slots. The rear I/O panel features PS/2, VGA, DVI-D, HDMI 1.4, four USB 3.2 Gen 1 Type-A ports (processor-connected), four USB 2.0 ports, a Gigabit LAN port via Realtek RTL8111H, and HD audio jacks. Onboard graphics outputs are only active with APUs that include integrated Radeon graphics. Audio is handled by a Realtek ALC892 codec delivering 7.1-channel High Definition Audio. Networking is provided by a Realtek 8111H Gigabit LAN controller. The board also includes one RGB LED strip connector, an EZ Debug LED for quick fault diagnosis, and a Clear CMOS jumper for easy BIOS recovery.
