Built around dual Socket E (LGA 4677) supporting 5th and 4th Generation Intel Xeon Scalable processors with a TDP up to 350W, this motherboard combines cutting‑edge CPU performance with DDR5 memory, PCIe 5.0, CXL1.1, high‑speed networking, and robust server‑grade management. Designed for 2U/4U rackmount servers, it balances performance, scalability, and power efficiency to meet the demands of 24/7 mission‑critical operations.

Processor & Platform Architecture

At its core, the SP2C741D16X-2T features a dual‑CPU design with 1+1 Socket E (LGA 4677), fully supporting both 5th and 4th Gen Intel Xeon Scalable processors. This dual‑socket configuration enables exceptional multi‑threaded performance, ideal for virtualization, database processing, big data analytics, and containerized cloud workloads. The Intel C741 chipset provides enterprise‑grade I/O, storage, and security capabilities, ensuring stable operation under heavy loads. With support for processors up to 350W TDP, the motherboard maintains strong power delivery and thermal regulation to sustain peak performance over extended periods. Compatibility across two generations of Xeon CPUs offers investment protection and flexible deployment for both new and existing server infrastructure.

Memory Subsystem: DDR5 Performance & Capacity

Memory bandwidth and capacity are critical for server performance, and the SP2C741D16X-2T excels with 16 DDR5 DIMM slots (8+8 configuration, 1DPC). Supporting 288‑pin DDR5 RDIMM and RDIMM‑3DS modules, the motherboard delivers high‑speed data access at up to 5600 MT/s for 5th Gen Intel Xeon Scalable processors and 4800 MT/s for 4th Gen processors. Each DIMM can reach up to 96GB for standard RDIMMs and up to 256GB for 4H RDIMM‑3DS, enabling extreme total memory capacity for memory‑intensive workloads such as in‑memory databases, virtual machines, and big data processing. The 1.1V low‑voltage design improves energy efficiency while maintaining signal integrity, making the memory subsystem both powerful and stable for enterprise environments.

PCIe 5.0 & CXL1.1 Expansion

The SP2C741D16X-2T offers industry‑leading expansion with six PCIe 5.0 x16 slots supporting CXL1.1, one PCIe 5.0 x8 slot, two MCIO (PCIe 5.0 x8) ports, and one M.2 slot (PCIe 5.0 x4, 22110/2280). PCIe 5.0 doubles the bandwidth of PCIe 4.0, enabling next‑generation GPUs, NVMe SSDs, SmartNICs, and accelerators for AI, machine learning, and high‑speed storage. CXL1.1 (Compute Express Link) enhances resource pooling, memory expansion, and efficient communication between CPUs and accelerators, optimizing performance for heterogeneous computing architectures. This extensive I/O supports versatile configurations, from dense storage servers to GPU‑accelerated computing nodes, ensuring long‑term compatibility with future hardware upgrades.

Storage Capabilities

Storage flexibility is a hallmark of the SP2C741D16X-2T. The Intel C741 chipset supports up to 13 SATA 6Gb/s ports with RAID 0/1/5/10 for traditional storage arrays. Three OCuLink ports (PCIe 3.0 x4 or 4 SATA 6Gb/s each) allow flexible expansion for SATA or NVMe storage, while the PCIe 5.0 M.2 slot provides an ultra‑fast boot or cache drive. This combination of high‑speed NVMe and reliable SATA storage meets diverse needs, from high‑IOPS database servers to cost‑effective bulk storage. Enterprise RAID functionality enhances data protection and availability, essential for business‑critical applications.

Networking & Server Management

Equipped with dual Intel X710‑AT2 10GbE RJ45 LAN ports, the motherboard delivers high‑bandwidth, low‑latency networking for data center traffic, supporting virtualization, software‑defined networking (SDN), and high‑speed inter‑server communication. For robust remote management, the board integrates an ASPEED AST2600 BMC controller with IPMI 2.0, iKVM, and virtual media (vMedia). This enables out‑of‑band monitoring, control, firmware updates, and remote troubleshooting without OS dependency, reducing downtime and operational costs. TGPIO support ensures precise time synchronization across devices, critical for clustered and time‑sensitive applications.

Physical Design & Reliability

Built in the EEB form factor (12.4” × 14” / 314.96 × 355.6 mm), the SP2C741D16X-2T fits standard 2U/4U rackmount chassis, ideal for space‑efficient data center deployment. The server‑grade PCB layout, premium power components, and optimized thermal design ensure stability under continuous heavy loads. Industrial‑grade capacitors and reinforced power delivery protect against voltage fluctuations, while enhanced grounding and signal isolation minimize interference. These features make the motherboard suitable for 24/7 operation in harsh data center environments, maximizing uptime and return on investment.
