Socket and processor fit

The board uses the LGA 1851 socket and Intel H810 chipset for Intel Core Ultra Processors Series 2. It is built for commercial buyers who need a stable, long-life platform in a micro-ATX form factor.

Memory ceiling and speed

Two DDR5 slots support up to 96 GB in dual-channel mode with XMP 3.0 profiles from 4400 to 6400 MT/s. This capacity limit is the single figure that decides whether the board fits the planned workload.

Install experience

The mATX layout keeps the PCIe 4.0 x16 slot and two M.2 sockets within easy reach. Q-DIMM latches and Q-LED Core diagnostics help first-time builders, while the single 8-pin CPU power connector must be seated firmly to avoid boot failures.

Questions about this item

What does the 96 GB DDR5 limit mean for a system built on this board?

The board has two DDR5 slots supporting up to 96 GB total in dual-channel mode, with speeds from 4400 to 6400 MT/s and XMP 3.0 or AEMP II profiles.

How does the PCIe 4.0 interface affect the M.2 slots and expansion cards?

The primary M.2 slot runs at PCIe 4.0 x4 and the second at x2, while the single x16 graphics slot and the x1 slot also operate at PCIe 4.0 speeds.

What physical space and mounting points does the mATX form factor need in a case?

The micro-ATX board fits standard mATX or larger cases, uses the LGA 1851 socket for Intel Core Ultra Series 2 CPUs, and provides four SATA 6 Gb/s ports plus two M.2 slots (2280 and 2242/2260/2280).
