ASUS NUC 15 Pro+ barebone for Core Ultra 7 255H

This barebone mini PC is built around the Intel Core Ultra 7 255H processor with 16 cores and 16 threads reaching a 5.1 GHz maximum turbo frequency. The aluminium chassis measures 5.67 x 4.41 x 1.65 inches and weighs 1.52 lbs. It ships without memory or storage, so the builder supplies both.

Suited for compact AI and graphics workloads

The integrated Intel Arc 140T GPU delivers 74 TOPS peak Int8 performance and the NPU adds 13 TOPS, giving 96 TOPS combined for local AI inference. Builders who need discrete graphics, more than two M.2 slots, or a larger power budget should consider a different platform.

DDR5 SO-DIMM or CSO-DIMM up to 96 GB

Two 262-pin slots accept DDR5-5600 SO-DIMM or DDR5-6400 CSO-DIMM modules with a 48 GB per-slot maximum. Populating both slots with 48 GB modules reaches the 96 GB ceiling; any other memory type will not fit.

Questions about this item

Will my existing DDR5-5600 SO-DIMMs work in the two 262-pin slots of this NUC 15 Pro+?

Yes, the board accepts two SO-DIMM DDR5-5600 modules up to 48 GB each for a total of 96 GB.

How can I confirm the Intel Arc 140T GPU is running at its 2.25 GHz maximum dynamic frequency?

Open the Intel Graphics Command Center or Task Manager performance tab and verify the GPU frequency reaches 2.25 GHz under load.

Does the barebone include any memory, storage or Wi-Fi antennas, or must I buy them separately?

The unit ships with no RAM and no SSD; you must supply two DDR5 SO-DIMMs and up to two NVMe drives. Wi-Fi 7 antennas are included.
