Built for Intel Core Ultra Series 2

This mATX board uses the Intel H810 chipset and an LGA 1851 socket to support Intel Core Ultra processors (Series 2). It targets commercial and small-form-factor builders who need a stable, long-life platform. The CSM programme guarantees extended availability and validated reliability for business deployments.

Memory support decides compatibility

Two 288-pin DDR5 slots run in dual-channel mode up to 96 GB total. Supported data rates span 4400 through 6400 MT/s in 200 MT/s steps. Intel XMP 3.0 and ASUS AEMP II profiles are both available for automatic overclocking.

Front USB Type-C header adds modern case support

One onboard USB 5 Gbps header drives a front-panel Type-C port, while a second USB 5 Gbps header supplies two additional Type-A ports. A USB 2.0 header adds two more legacy ports. Rear I/O already includes two USB 10 Gbps Type-A ports, so case connectivity is covered without adapters.

Questions about this item

What does the 96 GB maximum memory mean for a build using this board?

You can install up to 96 GB of DDR5 across the two 288-pin slots, running in dual-channel mode at speeds from 4400 up to 6400 MT/s with XMP 3.0 or AEMP II profiles.

How does the PCIe 4.0 x16 slot and the two M.2 slots share bandwidth on the H810 chipset?

The x16 slot connects directly to the Core Ultra Series 2 CPU at PCIe 4.0 x16, while M.2_1 runs at PCIe 4.0 x4 and M.2_2 at PCIe 4.0 x2, both wired through the H810 chipset.

What mounting holes and form factor does this mATX board use for case compatibility?

It follows the standard micro-ATX layout with four mounting holes, fitting any chassis that supports mATX or larger ATX form factors.
