Deep mini-ITX server board for Intel Core Ultra

The ASRock Rack W880D4ID-2Q is a single-socket LGA 1851 motherboard built on the Intel W880 chipset. It fits the deep mini-ITX footprint of 6.7 x 8.5937 inches and powers on from either an ATX supply or a 12 V DC source. Four DDR5 288-pin slots accept ECC or non-ECC UDIMM up to 48 GB at 5600 MT/s.

Network-first builds needing dual 25 GbE SFP28

Dual Intel E830 25 GbE SFP28 ports and a dedicated IPMI RJ45 make this board suited for storage nodes, hyper-converged clusters or edge appliances where high-throughput networking matters. Builds that require more than one CPU socket, more than 48 GB of memory, or more than a single PCIe 5.0 x16 slot should look elsewhere.

PCIe 5.0 x16 slot and three OCuLink connectors

The sole expansion slot is a PCIe 5.0 x16 connection wired to the CPU. Three OCuLink ports provide additional PCIe 4.0 x4 links, two of which can alternatively carry four SATA 6.0 Gb/s channels each. This layout determines how many accelerators, drives or NICs the system can support.

Questions about this item

What comes in the box with the W880D4ID-2Q and what must I buy separately?

The motherboard includes the I/O shield, SATA cables and mounting hardware; you must supply an LGA 1851 Intel Core Ultra Series 2 processor, DDR5 288-pin ECC or non-ECC UDIMMs, an ATX power supply or 12 V DC source, storage drives and a chassis that fits the 6.7" x 8.5937" deep mini-ITX form factor.

Which DDR5 capacity should I choose given the 48 GB maximum and four slots?

With four slots and a 48 GB limit, 16 GB modules would exceed the ceiling, so use 8 GB or smaller UDIMMs to populate all four slots or install fewer higher-capacity modules while staying at or below 48 GB total.

What does the 25 Gbps LAN speed mean for actual throughput on the dual SFP28 ports?

Each SFP28 port is driven by the Intel E830 controller at 25 Gbps line rate, providing two independent 25 GbE links for high-speed server networking.
