M393A4K40CB2-CVF Samsung 1x32GB DDR4 RDIMM ECC RAM

High-Density DDR4 ECC RDIMM Server Memory for Scalable Platforms with the M393A4K40CB2-CVF

The M393A4K40CB2-CVF is a 32GB DDR4 ECC Registered DIMM engineered for enterprise CPU platforms that require RDIMM signaling for stable multi-slot population and predictable memory timing. It targets x86 virtualization hosts and database nodes where memory integrity and deterministic latency are critical under sustained NUMA pressure and mixed read/write profiles.

Designed around a dual-rank x4, 72-bit ECC architecture, the M393A4K40CB2-CVF supports higher module counts without the signal loading limitations typical of unbuffered DIMMs. With 2933MT/s operation at 1.2V and JEDEC-aligned timings, it enables balanced bandwidth per channel while maintaining headroom for PCIe expansion and storage I/O concurrency. In dense servers, RDIMM topology helps sustain consistent performance as channels are filled, supporting scalable RAM footprints for in-memory datasets, larger VM consolidation ratios, and cache-intensive middleware tiers.

Why Choose the M393A4K40CB2-CVF?

The M393A4K40CB2-CVF provides a reliable density-to-performance increment for DDR4 RDIMM infrastructures, enabling capacity growth per socket without destabilizing signal integrity across populated channels. It is well suited for standardized fleet deployments where ECC protection, registered buffering, and repeatable behavior across nodes simplify validation, maintenance windows, and incremental scale-out.

Samsung’s server memory engineering emphasizes JEDEC compliance, controlled component quality, and long-term platform interoperability. This approach aligns with modern data centre requirements for predictable qualification cycles, consistent module behavior across batches, and reliable operation in thermally dense chassis environments.

Key Applications:

• Virtualization and VM consolidation
• Enterprise databases and OLTP
• In-memory caching and middleware
• Private cloud compute nodes
• Analytics and ETL pipelines
