Single-socket Xeon server board

The MBD-X11SPH-NCTF-O is an ATX motherboard built for a single Intel Xeon Scalable processor in an LGA 3647 Socket P package. It targets builders assembling 1U or 2U servers that need high core counts and large memory capacity in a standard form factor.

Straightforward ATX installation

The board follows the ATX layout so it fits common server chassis such as the SC847BE1C4-R1K23LPB or 826BE1C-R802LPB. Eight 288-pin DDR4 slots require careful population order for 1TB 3DS LRDIMM configurations. The single PCI-E 3.0 x16 slot shares bandwidth with the x8 slots, so plan add-in cards to avoid unexpected x8 or x0 operation.

Memory and storage headroom

Eight DDR4 channels support up to 1TB with 3DS LRDIMMs, 512GB with standard LRDIMMs or 256GB with RDIMMs at speeds from 1600 to 2666 MHz. Ten SATA 6.0Gb/s ports and eight SAS3 12Gbps ports from the Broadcom 3008 controller give dense drive connectivity, while dual 10GBase-T LAN handles heavy network loads.

Questions about this item

How can I verify the board is running correctly after installing a Xeon Scalable processor and DDR4 ECC memory?

The Aspeed AST2500 BMC provides IPMI 2.0 with KVM-over-IP and a dedicated LAN port; use it to watch POST codes, sensor readings and remote console output without a local display.

What comes in the retail pack and which essential parts must be sourced separately?

The retail pack contains the ATX motherboard; you must add a Socket P LGA-3647 Xeon Scalable CPU (up to 205 W TDP), DDR4 2666/2400/2133/1866/1600 MHz ECC RDIMM or LRDIMM modules, and storage drives for the 10 SATA 6.0 Gb/s or 8 SAS3 12 Gbps ports.

Which memory capacity tier should I choose — 256 GB RDIMM, 512 GB LRDIMM or 1 TB 3DS LRDIMM?

Match the tier to workload density: 256 GB with standard RDIMMs for general compute, 512 GB with LRDIMMs for larger datasets, and 1 TB with 3DS LRDIMMs when maximum capacity across all 8 DIMM slots is required.
