Socket AM4 DDR4 Platform

The MSI A320M Gaming Pro is a Micro ATX motherboard built around the AMD A320 chipset for Socket AM4 processors. It accepts AMD RYZEN series CPUs as well as 7th generation A-series and Athlon chips. Dual-channel DDR4 memory runs at 1866, 2133, 2400, 2667, 2933 (OC) or 3200 (OC) MHz up to 32GB total capacity.

Build Integration

A single PCIe 3.0 x16 slot provides x16 bandwidth with RYZEN CPUs and x8 with 7th generation A-series or Athlon CPUs. Two PCIe 2.0 x1 slots add further expansion room. Storage connects through one M.2 interface and four SATA III ports. Rear I/O supplies two USB 3.1 Gen1 ports and two USB 2.0 ports while internal headers add four more USB 2.0 connections. A Realtek 8111H Gigabit LAN port handles wired networking.

Included Extras

The package ships with the motherboard, a CMOS battery, one SATA cable and a chassis I/O back panel. No WiFi antenna is included because the board lacks a built-in WiFi module. Realtek ALC887 audio delivers 7.1 channel output for surround sound. These bundled items cover the essentials for a basic system assembly.

Questions about this item

How much DDR4 memory can the MSI A320M Gaming Pro actually hold?

The board supports up to 32 GB of dual-channel DDR4 across its two slots.

How loud or hot does the Realtek 8111H Gigabit LAN and ALC887 audio get during all-day use?

Both controllers are low-power integrated chips; they add negligible heat and produce no audible noise under continuous operation.

Which Ryzen processor and DDR4 modules do I need to already own for this motherboard to work?

Any Socket AM4 Ryzen CPU or 7th-gen A-series/Athlon plus DDR4 DIMMs rated 1866–3200 MHz will boot the system.
