M393A4K40BB1-CRC Samsung 1x32GB DDR4 RDIMM ECC RAM

Enterprise DDR4 ECC Registered RDIMM for Dense Server Memory Scaling with the M393A4K40BB1-CRC

The M393A4K40BB1-CRC is a 32GB Samsung DDR4 ECC Registered DIMM engineered for modern dual-socket x86 server platforms where memory reliability and predictable latency are mandatory. In virtualization clusters and private cloud nodes, the registered buffer improves signal integrity across heavily populated memory channels, enabling higher DIMM density per CPU without compromising stability under sustained load.

Designed to align with PCIe-based expansion and NVMe-centric storage tiers, M393A4K40BB1-CRC supports balanced system architecture: adequate memory capacity per core for consolidation, consistent error correction for transactional workloads, and dual-rank x4 organization that helps maintain bandwidth utilization at scale. For enterprise databases and scale-out compute, this module provides the headroom to allocate larger guest memory footprints, reduce paging pressure, and sustain predictable performance in mixed I/O and compute profiles.

Why Choose the M393A4K40BB1-CRC?

Choosing M393A4K40BB1-CRC supports a deployment model focused on density-to-performance efficiency: 32GB per slot simplifies capacity planning across multi-node racks while ECC Registered operation increases uptime for business-critical services. The module’s DDR4 RDIMM architecture scales cleanly in servers with high DIMM population, helping standardize configurations for repeatable rollouts and maintenance.

Samsung memory is built around disciplined process control and validation for enterprise duty cycles, emphasizing long-term compatibility with data centre platform requirements. The manufacturing approach prioritizes consistent electrical characteristics, robust ECC behavior, and adherence to industry standards required for stable server qualification.
