Core Ultra 5 225H barebone for compact workstations

The ASUS NUC15CRKU5 is a 0.48L mini PC built around an Intel Core Ultra 5 225H processor with 14 cores and Intel Arc graphics. It targets professionals who need vPro security and quad 4K display output in a tool-less chassis that fits behind a monitor or on a crowded desk.

Dual-channel DDR5-5600 support up to 96GB

Two 262-pin SO-DIMM slots accept DDR5 memory only, letting you configure up to 96GB for heavy multitasking. Storage uses one M.2 2280 NVMe PCIe G4x4 slot and one M.2 2242 NVMe PCIe x4 slot, so you choose both capacity and speed without proprietary parts.

Check DDR5 SO-DIMM stock and 2.5GbE cabling

This unit ships without RAM or storage, so you must source compatible DDR5-5600 modules and NVMe drives before assembly. Verify your network infrastructure supports 2.5Gbps Ethernet and that your displays use HDMI 2.1 or Thunderbolt 4 with DisplayPort 2.1 for full quad 4K operation.

Questions about this item

How much DDR5-5600 memory can I add to the two SO-DIMM slots later?

The board accepts up to 96 GB of dual-channel DDR5-5600 across its two 262-pin slots.

Which thermal limit appears first when the Core Ultra 5 225H runs at 4.90 GHz for long periods?

The processor's 4.90 GHz boost clock is the ceiling; sustained loads will throttle to stay within the chip's power envelope.

How loud is the cooling fan when the 0.48 L chassis runs all day?

The tool-less slim chassis uses a single internal fan; noise rises with load but stays within typical mini-PC office levels.
