Dual LGA 3647 server platform

The Supermicro MBD-X11DPI-N-B is an extended ATX motherboard built for dual-socket Intel Xeon Scalable processors. It targets operators who need high core counts and large memory capacity in a single chassis. Two sockets support up to 205 W TDP each with dual UPI links at 10.4 GT/s.

Fits dense compute and memory-heavy workloads

This board suits virtualisation hosts, database servers and HPC clusters that can use 16 DIMM slots and 14 SATA ports. It is not for builds that require a single-socket design, standard ATX dimensions, or more than two GbE ports without add-in cards. The form factor demands an E-ATX compatible case.

16 DDR4 slots scale to 2 TB

Sixteen slots accept ECC RDIMM or LRDIMM modules at 2666, 2400 or 2133 MHz, reaching 2 TB with 3DS parts. The C621 chipset provides four PCI-E 3.0 x16 slots, two x8 slots and dual Gigabit LAN from the PCH. Onboard Aspeed AST2500 handles video and management.

Questions about this item

Which DDR4 memory types and speeds does the MBD-X11DPI-N-B support for its 16 DIMM slots?

The board accepts ECC RDIMM and LRDIMM modules at 2666, 2400 or 2133 MHz, with a maximum capacity of 2 TB using 3DS RDIMM or 3DS LRDIMM.

Can I keep my existing PCIe 3.0 x16 and x8 add-in cards when moving to this motherboard?

Yes, the board provides four PCIe 3.0 x16 slots and two PCIe 3.0 x8 slots, so current PCIe 3.0 cards will fit and operate at their native speeds.

How can I confirm the dual Gigabit LAN ports are active after installation?

Connect network cables to the two RJ45 ports; link LEDs on each port will light when a live connection is detected, and the OS will list two Gigabit Ethernet adapters.
