ASRock Rack EC266D2I Mini-ITX server motherboard LGA 1700 DDR5 64GB

Compact server board for single-socket Xeon E-2400

The ASRock Rack EC266D2I is a Mini-ITX motherboard designed for the LGA 1700 socket and Intel Xeon E-2400 series processors, with support for Pentium Gold G7400 and G7400T CPUs. It targets system integrators and IT professionals who need a dense, single-socket platform with ECC memory and multiple storage lanes in a 6.7-inch square footprint. The board ships new and includes a 24-pin ATX adapter cable for standard power supplies.

Sustained load behaviour

Under continuous workloads the single PCIe 5.0 x16 slot connects directly to the CPU, providing full bandwidth for accelerators or high-throughput NICs without PCH contention. Two OCuLink connectors — one PCIe 4.0 x4 and one PCIe 3.0 x4 — each support four SATA 6Gb/s drives, allowing up to eight drives to operate simultaneously through the chipset. The Aspeed AST2600 BMC and dual Intel I210 1GbE ports remain active for remote management and network traffic during extended operation.

64 GB DDR5 ECC ceiling decides fit

Maximum memory capacity is 64 GB across two 288-pin DDR5 4800 slots with ECC UDIMM support, and the qualified vendor list validates 16 GB and 32 GB modules at 4800 and 5600 MT/s. Builds requiring more than 64 GB or non-ECC consumer memory cannot use this board, while configurations staying within the limit gain error correction and validated stability for always-on services.
