M393A4K40BB0-CPB Samsung 1x32GB DDR4 RDIMM ECC RAM

Enterprise DDR4 RDIMM Server Memory Upgrade for ECC-Registered Platforms with the M393A4K40BB0-CPB

The M393A4K40BB0-CPB is a Samsung 32GB DDR4 ECC Registered DIMM engineered for predictable performance and signal integrity in modern CPU server platforms that depend on registered memory for scalable capacity. In multi-socket systems, the RDIMM register reduces electrical loading on the memory controller, helping maintain stability as channels are populated and enabling consistent latency characteristics for virtualized and database-heavy environments.

Built as a low-profile 288-pin module, the M393A4K40BB0-CPB supports dense chassis designs with constrained airflow paths while maintaining enterprise operating margins at 1.2V. Its dual-rank x4 organization and 72-bit ECC data path support robust error detection and correction for long-running compute nodes. While PCIe and storage architectures define I/O throughput, memory bandwidth and reliability remain the primary constraint for consolidation ratios, in-memory working sets, and query execution, making the M393A4K40BB0-CPB a targeted upgrade for RAM-bound server workloads.

Why Choose the M393A4K40BB0-CPB?

The M393A4K40BB0-CPB provides a practical density-to-reliability profile for enterprises scaling DDR4 RDIMM footprints without redesigning the platform. By standardizing on the M393A4K40BB0-CPB across compatible hosts, IT teams can simplify sparing, maintain balanced channel population, and expand memory capacity methodically while keeping ECC protection and registered signaling behavior aligned with server-class deployment requirements.

Samsung designs enterprise memory to meet data centre uptime expectations through disciplined manufacturing control, electrical validation, and consistency across production. This focus supports stable operation in continuous-duty environments and aligns with established DDR4 server standards for interoperability and lifecycle planning.
