MSI Pro A320M-A Pro DDR4 AMD Motherboard

The MSI Pro A320M-A Pro is a Micro-ATX form factor motherboard built on the AMD A320 chipset, designed around the AM4 socket. It supports AMD Ryzen 1st, 2nd, and 3rd Generation processors, including Ryzen with Radeon Vega Graphics, Athlon with Radeon Vega Graphics, and A-series/Athlon X4 desktop processors. Its compact 8.9 x 7.4 in (22.6 x 18.7 cm) footprint fits a wide range of Micro-ATX cases, making it a practical choice for compact office or entry-level builds. Memory is handled by two DDR4 DIMM slots in a dual-channel configuration, supporting up to 64 GB of non-ECC UDIMM memory (ECC UDIMM supported in non-ECC mode). Speeds range from 1866 MHz up to 3200 MHz via the A-XMP OC profile, requiring ComboPI 1.0.0.3-based BIOS or later for full 64 GB capacity. Storage connectivity is provided by four SATA 6 Gb/s ports with RAID 0, 1, and 10 support via the A320 chipset. Expansion options include one PCIe 3.0 x16 slot (running at x16 with full Ryzen CPUs, x8 with Ryzen APUs, x4 with Athlon APUs) and one PCIe 2.0 x1 slot. Display outputs on the rear I/O — active only when using an APU — include one DVI-D port (up to 1920×1200 @ 60 Hz) and one HDMI 1.4 port (up to 4096×2160 @ 30 Hz), with up to 2048 MB shared video memory. USB connectivity totals six USB 3.2 Gen 1 (SuperSpeed) ports — four Type-A on the rear panel plus two via an internal header — and six USB 2.0 ports, two rear panel plus four via internal headers. Networking is handled by a Realtek 8111H Gigabit LAN controller. Audio is delivered through a Realtek ALC892/ALC897 codec providing 7.1-channel High Definition Audio output. Fan control is managed through one 4-pin CPU fan header and one 4-pin system fan header, configurable through MSI's CLICK BIOS 5 interface. Additional internal connectors include a TPM module header, chassis intrusion connector, serial port, and Clear CMOS jumper. The board ships with a 3-year manufacturer warranty.
