Deep mini-ITX server motherboard
The ASRock Rack EC266D4ID-2T/X550 is a deep mini-ITX server motherboard measuring 6.7" x 8.2". It uses the Intel C266 chipset and LGA 1700 socket to support one Intel Xeon E-2400 series or Intel Pentium Gold G7400/G7400T processor up to 95W TDP. The board targets builders who need a compact platform with dual 10GbE and multiple storage links.
Installation notes and common issues
The deep mini-ITX footprint fits standard mini-ITX mounting holes but extends deeper, so verify chassis clearance before fitting. Four 288-pin DDR5 slots accept ECC UDIMMs; populate all four only with validated modules from the QVL to avoid training failures. Three OCuLink connectors share bandwidth with SATA ports, so plan drive topology to prevent lane conflicts.
Storage and network capacity
Dual Intel X550 controllers deliver two 10Gbps RJ45 ports for high-throughput networking. Storage connectivity includes one PCIe 5.0 x16 slot, three OCuLink interfaces providing up to eight SATA 6Gb/s ports, and two M.2 2280 slots wired for PCIe 4.0 x4. Maximum memory capacity is 128GB across four DDR5 4400 slots.

이 상품에 대한 질문
How can I verify the ASRock Rack EC266D4ID-2T/X550 is working correctly after installation?
Check that the Aspeed AST2600 video outputs a signal through the D-Sub port and that both Intel X550 10Gbps LAN ports show link lights when cables are connected.
What comes in the box with the EC266D4ID-2T/X550 and what must I purchase separately?
The motherboard includes one USB 3.2 Gen1 19-pin header; you must buy an LGA 1700 Xeon E-2400 or Pentium Gold G7400 CPU, DDR5 4400 ECC UDIMMs up to 128 GB, and storage drives for the M.2 and OCuLink connectors.
Which DDR5 capacity should I choose for the four 288-pin slots on this board?
The board supports up to 128 GB total; validated modules include 16 GB, 32 GB and 48 GB DDR5 4800 RDIMMs, so populate all four slots with matching capacities to reach your target.
