M393A4K40CB2-CTD Samsung 1x32GB DDR4 RDIMM ECC RAM

High-Density DDR4 RDIMM Server Memory featuring ECC Registered Reliability with the M393A4K40CB2-CTD

The M393A4K40CB2-CTD is a 32GB DDR4-2666 ECC Registered RDIMM engineered for Intel Xeon and AMD EPYC-class DDR4 platforms where predictable latency and error containment are required at scale. In multi-socket CPU servers, the registered buffering of the M393A4K40CB2-CTD stabilizes signal integrity across populated channels, supporting higher DIMM counts per node without compromising platform-level memory training and uptime targets.

Designed for PCIe-based expansion and storage-centric server topologies, the M393A4K40CB2-CTD complements balanced CPU nodes running NVMe, SAS, or SATA storage tiers by ensuring the memory subsystem does not become a bottleneck for I/O completion and caching behavior. Its dual-rank x4 organization and JEDEC-aligned operation at 1.2V are well-suited to virtualization clusters, database services, and general-purpose compute where consistent bandwidth per channel matters more than peak-bin overclock profiles.

Why Choose the M393A4K40CB2-CTD?

The M393A4K40CB2-CTD provides an efficient density-to-slot ratio for scaling memory capacity in existing DDR4 fleets while maintaining enterprise-grade resilience through ECC and registered architecture. For IT teams standardizing server builds, the M393A4K40CB2-CTD supports repeatable deployments, predictable behavior under mixed workloads, and straightforward capacity growth by adding identical modules across channels and sockets.

Samsung designs server memory with a focus on lifecycle stability, strict adherence to JEDEC specifications, and validated interoperability aligned with modern data centre qualification processes. This engineering approach helps ensure that modules such as the M393A4K40CB2-CTD deliver consistent performance characteristics across long service windows in always-on infrastructure.

Key Applications:

• CPU-based virtualization clusters
• General-purpose compute nodes
• Database servers on DDR4 platforms
• In-memory caching within DDR4 constraints
