Supermicro MBD-X11DAC Motherboard

The Supermicro MBD-X11DAC is a high-performance E-ATX motherboard designed for demanding server and workstation environments that require high core density, large memory capacity and extensive PCIe expansion. With dual LGA 3647 sockets, it supports 1st and 2nd Gen Intel® Xeon® Scalable processors up to 205W TDP, enabling robust multi-threaded workloads.

Engineered for memory-intensive applications, the board provides 16 DIMM slots and supports up to 4TB of 3DS ECC DDR4-2933 RDIMM/LRDIMM. ECC support enhances system reliability by detecting and correcting memory errors, which is critical in professional and data-centric deployments.

• CPU platform: Dual LGA 3647 sockets for 1st/2nd Gen Intel® Xeon® Scalable processors (no CPU included in the package; maximum TDP 205W per socket).
• Form factor: E-ATX, suitable for compatible server and workstation chassis that support extended ATX motherboards.
• Memory subsystem: 16 DIMM slots supporting up to 4TB of 3DS ECC DDR4-2933 RDIMM/LRDIMM for memory-heavy workloads.
• Expansion capabilities: 3x PCI Express 3.0 x16 and 3x PCI Express 3.0 x8 slots provide flexible options for compute accelerators, storage controllers or professional graphics cards.
• USB connectivity: 6x USB 3.0 ports (4 on the rear I/O panel and 2 via internal header) for high-speed peripheral and external storage connectivity.
• Network interfaces: 2x RJ-45 1Gb/s Ethernet ports for redundant or segmented network configurations.
• Audio subsystem: Integrated 7.1 HD Audio for multi-channel audio output in workstation scenarios.
• Legacy and additional I/O: PS/2 combo port for keyboard/mouse and other standard rear-panel connections, supporting mixed modern and legacy peripherals.
• Storage considerations: No onboard M.2 NVMe slots, allowing integrators to plan storage around PCIe add-in cards or other supported storage interfaces on the platform.
• Reliability: 36-month manufacturer warranty provides long-term platform stability for continuous operation.

This motherboard is suited to technical users and system integrators building compute- and memory-intensive servers or workstations, where high PCIe bandwidth, large ECC memory capacity and dual-socket processing are required. Its feature set enables flexible configuration of expansion cards and external storage while maintaining enterprise-grade reliability.
