AM4 socket for Ryzen and Athlon builds

The ASUS Prime A320M-K is a Micro-ATX motherboard built around the AMD A320 chipset and the AM4 socket. It accepts Ryzen processors with integrated Radeon Vega graphics as well as 7th generation A-series and Athlon X4 CPUs. The board targets budget system builders who need essential modern connectivity in a compact form factor.

Two DDR4 slots supporting 32 GB maximum

Memory expansion is limited to two 288-pin DDR4 slots running in dual-channel mode with a 32 GB ceiling. Supported speeds reach DDR4 3200 and 2933 via overclocking on Ryzen 1st generation and Vega APUs, while 7th generation A-series and Athlon X4 processors top out at DDR4 2400. This capacity and slot count defines the upgrade ceiling for any build using this board.

DIGI+ VRM and Fan Xpert manage sustained loads

The onboard DIGI+ VRM regulates processor power delivery in real time, reducing energy draw and stabilising voltage during extended workloads. Fan Xpert provides advanced fan headers that adjust speeds based on system temperatures, helping the board maintain thermal equilibrium when the CPU and M.2 storage operate continuously under load.

Questions about this item

What does the 32 GB maximum memory mean for a build using this board?

The board has two DDR4 slots and supports up to 32 GB total, so you can install two 16 GB modules for the full capacity.

How does the M.2 slot's PCIe 3.0 x4 interface limit drive performance?

The M.2 socket runs at PCIe 3.0 x4, which caps sequential throughput at the PCIe 3.0 x4 ceiling for compatible NVMe drives.

What size case and mounting holes does this Micro-ATX board need?

The Micro-ATX form factor fits standard Micro-ATX or larger cases with the matching mounting hole pattern.
