M391A4G43MB1-CTD
High-Density DDR4 ECC UDIMM Server Memory designed for stable edge compute with the M391A4G43MB1-CTD
The M391A4G43MB1-CTD is a 32GB DDR4 ECC UDIMM built for x86 server and appliance platforms that require unbuffered ECC memory rather than RDIMM/LRDIMM architectures. By operating at the JEDEC-standard DDR4-2666 data rate and 1.2V, the module supports predictable latency behavior and power efficiency in entry server nodes and embedded systems where thermal and capacity headroom are tightly managed.
Architecturally, the M391A4G43MB1-CTD aligns with CPU memory controllers validated for ECC UDIMM operation, enabling single-bit error correction across a 72-bit data path to protect uptime for security, routing, and infrastructure services. Its dual-rank x8 organization improves effective bank-level parallelism for mixed workloads such as virtualization control planes, caching layers, and packet inspection. The low-profile 288-pin form factor helps maintain front-to-back airflow and clearance in compact chassis with dense PCIe expansion, while freeing storage bays and I/O slots for NVMe/SATA designs typical of edge and branch deployments.
Why Choose the M391A4G43MB1-CTD?
The M391A4G43MB1-CTD delivers a practical density-to-reliability balance for platforms that scale via ECC UDIMM population, enabling consistent memory availability without changing server class or introducing buffered DIMM dependencies. It is well-suited to standardized rollouts where repeatable behavior, straightforward qualification, and field-serviceable upgrades are required across multiple node types.
Samsung engineers this module for enterprise duty cycles with controlled component selection and rigorous validation to support long-term stability in always-on environments. The design aligns with modern data centre standards for predictable interoperability, lifecycle continuity, and disciplined electrical characteristics at JEDEC operating points.
Key Applications:
- DDR4 ECC UDIMM server memory expansion
- Entry-level rack and tower server nodes
- Networking and security appliances
- Embedded x86 edge platforms
- Virtualization infrastructure services
