Barebone mini PC without memory or storage

The ASRock Industrial NUC BOX-225H is a barebone mini PC built around an Intel Core Ultra 5 225H processor with integrated Intel Arc graphics. It ships without memory or storage, allowing the builder to choose DDR5 6400 SO-DIMMs up to 96 GB across two slots and up to two PCIe Gen4 M.2 SSDs plus one SATA drive.

For integrators who need a compact AI-ready platform

This unit suits system integrators and developers who want a small footprint with dual 2.5 GbE LAN, Wi-Fi 6E, Bluetooth 5.3 and quad-display support via two HDMI 2.1 ports, USB4 and USB-C DisplayPort. It is not for buyers who expect RAM or an SSD included, nor for builds that require legacy COM ports or more than two M.2 Key M slots.

Dual-channel DDR5 6400 support up to 96 GB

The two 262-pin SO-DIMM slots run in dual-channel mode at 6400 MT/s and accept modules up to 48 GB each, making memory capacity the key specification that determines whether this barebone fits the workload.

Questions about this item

How much DDR5-6400 memory can the two 262-pin SO-DIMM slots accept?

Each slot supports up to 48 GB DDR5-6400 modules, giving a total of 96 GB in dual-channel configuration.

Which storage interface will saturate first when the PCIe Gen4 x4 M.2 slots are driven continuously?

The PCIe Gen4 x4 link on each M.2 Key M slot is the throughput ceiling for sustained SSD workloads.

Does the 19 V power adapter limit the Intel Core Ultra 5 225H under all-day loads?

The included 19 V adapter is sized for the platform; sustained heavy compute will draw up to its rated output.
