Dual LGA 3647 server board for high-density compute

The Supermicro MBD-X11DPI-NT-O is a dual-socket Extended ATX motherboard built for Intel Xeon Scalable processors in the LGA 3647 package. It targets builders assembling multi-socket servers that need large memory capacity and abundant storage connectivity in a single node. The board supports CPU TDPs up to 205 W and two UPI links at 10.4 GT/s for inter-socket bandwidth.

Sixteen DDR4 slots scale to 2 TB with 3DS modules

Memory capacity is the decisive spec: sixteen DIMM slots accept ECC RDIMM or LRDIMM at 2666, 2400 or 2133 MHz, reaching 2 TB when 3DS parts are populated. Standard RDIMMs without 3DS stacking will not reach the maximum stated capacity, so buyers planning the full 2 TB must source 3DS-rated modules.

E-ATX layout demands a compatible chassis

The Extended ATX form factor requires a server case with matching mounting holes and sufficient clearance for the dual-socket keep-out zone. Fourteen SATA 6.0 Gb/s ports and two internal NVMe x4 connectors create dense cable routing; installers should verify backplane or drive-bay cabling reaches all headers before finalising the build.

Questions about this item

How much memory can the board actually address once populated with 3DS modules?

The board supports up to 2 TB of 3DS ECC RDIMM or LRDIMM across its 16 DIMM slots at DDR4-2666 speeds.

What does the dual 10GBase-T LAN cap at in real throughput?

The Intel X722 and X557 controllers provide two 10GBase-T ports, but the specification lists maximum LAN speed as 2 x 1 Gbps.

What chassis clearance does the E-ATX form factor and dual LGA 3647 sockets require?

Extended ATX dimensions with two LGA 3647 sockets need a full-height E-ATX server chassis that provides enough width for both CPU coolers and the 16 DIMM slots.
