Our take on the Supermicro Dual Socket P (LGA 3647) Motherboard X11DPT-B

The Supermicro X11DPT-B is a dual-socket LGA 3647 server board built for Supermicro's BigTwin multi-node chassis, not for standard rack or tower cases. It runs first- and second-generation Intel Xeon Scalable processors on the C621 chipset, with second-gen chips needing BIOS 3.0a or later. Its value is density: two sockets and high memory capacity in a node board that shares a chassis with other nodes. Buyers should confirm the BigTwin node compatibility before committing, since it will not fit generic builds.

Pros
  • Two LGA 3647 sockets for up to 28-core Xeon Scalable chips
  • Supports both Skylake-SP and Cascade Lake-SP generations
  • High memory capacity for its node form factor
  • Built for dense BigTwin deployments
  • C621 chipset with broad enterprise I/O
Cons
  • Fits only Supermicro BigTwin nodes, not standard cases
  • Second-gen CPUs require BIOS 3.0a or newer
  • No consumer features such as audio or display outputs
  • Needs registered ECC server memory and server power
  • Firmware and platform setup assume an experienced admin

About the Supermicro Dual Socket P (LGA 3647) Motherboard X11DPT-B

The Supermicro X11DPT-B is a dual-socket server motherboard built for Supermicro BigTwin multi-node systems. It uses two Socket P (LGA 3647) sockets and the Intel C621 chipset. It supports 1st Generation Intel Xeon Scalable (Skylake-SP) and 2nd Generation Intel Xeon Scalable (Cascade Lake-SP) processors, with up to 28 cores per processor and up to 205W TDP. BIOS version 3.0a or later is required for 2nd Generation processors.

The board has 24 DDR4 ECC DIMM slots for up to 6TB of memory. It also supports Intel Optane DC Persistent Memory, for up to 9TB of total memory when combined with standard modules. Hybrid memory configurations are available with Cascade Lake processors.

Management is handled by an ASPEED AST2500 BMC with IPMI 2.0, KVM over LAN and Virtual Media over LAN. Networking uses Supermicro's SIOM (Super I/O Module) architecture, so the network module can be chosen to suit the deployment.

Questions and answers

Will this board fit a normal ATX case?
No. It is a BigTwin node board designed for Supermicro's multi-node chassis, so it will not mount in a standard rack or tower case.
Does it support second-generation Xeon Scalable CPUs?
Yes, but only with BIOS version 3.0a or later. Older firmware will not boot Cascade Lake-SP processors.
What memory does it take?
It uses DDR4 registered ECC server memory in the DIMM slots Supermicro specifies for the platform. Check the board's memory population rules before buying modules.
Is it a good choice for a first server build?
Not really. It assumes a BigTwin chassis, server power and firmware management experience. A standard ATX server board is easier for a single-node build.
What is in the box?
The board itself. Cabling, node trays and chassis parts come with the BigTwin system, not with the board.
