Supermicro MBD-H12SSW-IN Motherboard

The Supermicro MBD-H12SSW-IN is a server-grade motherboard engineered for demanding data center, virtualization, and high-memory workloads. Based on the AMD SP3 platform, it supports single-socket AMD EPYC 7001/7002 processors, delivering high core density and advanced I/O capabilities in a compact form factor of 8.15" x 13.05" (20.7cm x 33.15cm).

Processor and memory subsystem

• Socket: SP3, compatible with AMD EPYC 7001/7002 series (single CPU socket)
• Memory slots: 8 DIMM slots for scalable memory configurations
• Maximum memory: up to 2TB 3DS ECC DDR4-3200 RDIMM/LRDIMM
• ECC support for improved reliability and data integrity in mission-critical environments
• Optimized for high-bandwidth memory access in virtualization, database, and in-memory workloads

Expansion and storage

• PCIe interface: 1x PCI-E 4.0 x32 (Left Riser), 1x PCI-E 4.0 x16 (Right Riser)
• Support for high-performance add-in cards such as HBAs, RAID controllers, or network adapters (depending on riser configuration)
• Integrated storage expansion via 2x M.2 NVMe slots for low-latency SSDs
• Suitable for OS boot drives or high-speed cache tiers

Connectivity and I/O

• Network interfaces: 2x RJ-45 1Gb/s Ethernet ports for redundant or segmented networking
• USB: 7x USB 3.0 ports (4 rear, 2 via headers, 1 Type A) for service tools, external storage, or maintenance
• Designed for integration into server chassis that support riser-based PCIe expansion

Form factor and deployment

• Board size: 8.15" x 13.05" (20.7cm x 33.15cm), suitable for compatible rackmount or tower server enclosures
• Single-socket architecture simplifies power and thermal design while maintaining high compute density
• Ideal for virtualization hosts, application servers, and memory-intensive workloads where reliability and throughput are critical

Reliability and service

• Manufacturer warranty: 36 months
• Enterprise-class design targeting continuous operation in professional IT environments

The Supermicro MBD-H12SSW-IN provides a robust platform for building efficient, scalable servers based on AMD EPYC 7001/7002 processors, combining high memory capacity, PCIe 4.0 expansion, and dual 1GbE networking in a server-optimized layout.
