Socket AM4 Micro-ATX Platform

The MSI B350M GAMING PRO is a Micro-ATX motherboard built for AMD Socket AM4 processors. It supports first and second generation Ryzen CPUs as well as 7th Gen A-Series and Athlon chips. The board delivers a compact foundation for mainstream desktop builds.

Dual-Channel DDR4 and Core Connectivity

Four memory slots run dual-channel DDR4 at speeds up to 3200 MHz when overclocked, with a 32 GB capacity ceiling. Expansion covers one PCIe 3.0 x16 slot and two PCIe 2.0 x1 slots. Storage connects through four SATA III ports and one M.2 interface. Realtek ALC887 audio provides 7.1-channel output while a Realtek 8111H controller handles Gigabit LAN.

Upgrade Path From Older AM3+ Systems

This board replaces legacy platforms that cannot run Ryzen architectures. The jump is worthwhile when moving to Zen or Zen+ cores for higher instructions-per-clock and modern instruction sets. It also adds native USB 3.1 Gen1 ports and M.2 support absent on prior chipsets.

Questions about this item

Which AMD processors fit this Socket AM4 board?

First- and second-generation Ryzen CPUs and APUs with AM4 pins are supported, plus 7th-generation A-series and Athlon chips. Ryzen parts run the top PCIe slot at x16; A-series and Athlon run it at x8.

What is the highest DDR4 speed the board can run?

The board natively supports DDR4 up to 2400 MHz and can reach 2667, 2933 or 3200 MHz when overclocked. Four slots take a maximum of 32 GB in dual-channel mode.

What storage connectors are available?

Four SATA III ports and one M.2 interface are provided. The M.2 slot runs over SATA, so only SATA-based M.2 drives will work.
