Micro-ATX server board for Intel Core Ultra Series 2

The ASRock Rack W880M WS is a Micro-ATX server motherboard built around the Intel W880 chipset and the LGA 1851 socket. It accepts a single Intel Core Ultra Desktop Processor (Series 2) and provides four DDR5 288-pin slots running at 5600 MT/s with ECC support. Maximum memory capacity is 48GB.

Suits compact servers needing ECC memory

This board fits builders who want a small-form-factor server with error-correcting memory, eight SATA 6.0Gb/s ports supporting RAID 0/1/5/10, and two M.2 2280 slots wired for PCIe 4.0 x4. It is not for deployments that require more than 48GB of system memory, dual-socket scaling, or 10GbE networking.

Maximum memory capacity is 48GB

The four DIMM slots top out at 48GB of DDR5 5600 ECC or non-ECC UDIMM. If your application dataset exceeds that limit you will need a platform with a higher supported capacity.
