Barebone mini PC with 16-core Ryzen 9

The Minisforum MS-A2-9955HX is a barebone mini workstation built around a 16-core, 32-thread AMD Ryzen 9 9955HX processor that reaches 5.4 GHz. It ships with 64 GB of DDR5-5600 memory in dual-channel configuration and supports up to 96 GB across two SO-DIMM slots. Integrated AMD Radeon 610M graphics run at 2.2 GHz. No storage or operating system is included.

Adds 10 GbE SFP+ and PCIe 4.0 expansion

This unit upgrades connectivity with two 10 Gbps SFP+ ports based on Intel X710 controllers, plus dual 2.5 GbE RJ45 ports using Realtek RTL8125 and Intel I226-V. A PCIe 4.0 x16 slot operates at x8 and supports bifurcation for add-in cards. Storage capacity expands through one M.2 2280/U.2 slot accepting up to 15 TB U.2 drives and two additional M.2 2280/22110 slots for NVMe SSDs up to 4 TB each.

Suits multi-display workstations needing

Builders who want triple 8K@60 Hz output via HDMI 2.1 and two USB-C DP Alt Mode ports will benefit from the video flexibility. The 10 GbE SFP+ links serve network-attached storage or server clusters. Buyers who need discrete GPU performance, more than three display outputs, or a pre-installed OS and SSD should look at other platforms.

Questions about this item

What size M.2 NVMe SSD does the 2280 slot accept and what is the maximum capacity per slot?

The two M.2 2280/22110 slots each support NVMe SSDs up to 4 TB per slot, running at PCIe 3.0 x4 by default and up to PCIe 4.0 x4.

How do I install an M.2 drive and what step is commonly missed?

Remove the bottom cover, insert the M.2 2280 or 22110 NVMe SSD at an angle into the slot, secure it with the screw, then enable the drive in BIOS — many users forget the BIOS step.

When will the pre-installed 64 GB DDR5 memory need replacement or expansion?

The 64 GB DDR5-5600 SO-DIMM kit can be expanded to 96 GB using both 262-pin slots; replace modules only if a fault occurs or workloads exceed 96 GB.
