M393A4K40DB2-CTD Samsung 1x32GB DDR4 ECC RAM

Enterprise DDR4 ECC Registered RDIMM Memory Expansion with the M393A4K40DB2-CTD

The M393A4K40DB2-CTD is a Samsung 32GB DDR4 ECC Registered RDIMM designed for 2-socket Intel Xeon and AMD EPYC DDR4 generations that depend on deterministic memory behavior under sustained concurrency. By using a registered DIMM architecture with ECC, the M393A4K40DB2-CTD improves signal integrity and availability characteristics compared with unbuffered designs, supporting stable operation as memory channels are populated for capacity-driven builds.

Architecturally, the M393A4K40DB2-CTD targets balanced CPU-to-memory throughput on DDR4-2666 JEDEC platforms where virtualization density, private cloud consolidation, and database buffer growth are limited more by memory capacity and reliability than by PCIe expansion. The dual-rank, 72-bit data path aligns with enterprise controller expectations, while the low-profile 288-pin form factor improves mechanical compatibility in high-density rack servers and airflow-focused chassis layouts. Deploy the M393A4K40DB2-CTD to scale VM counts, enlarge in-memory caches, and reduce paging pressure without replatforming storage or PCIe subsystems.

Why Choose the M393A4K40DB2-CTD?

The M393A4K40DB2-CTD provides a practical density-to-performance profile for DDR4 nodes that must remain predictable at scale, enabling higher channel population while maintaining enterprise stability through ECC and registered buffering. For standardization initiatives, the M393A4K40DB2-CTD supports repeatable configuration, straightforward capacity planning, and controlled expansion across fleets of similar Xeon or EPYC servers.

Samsung memory engineering emphasizes tight process control, qualification discipline, and consistency across production lots to meet modern data centre expectations for uptime and lifecycle management. The M393A4K40DB2-CTD is built to integrate cleanly into server validation matrices and operational change procedures common to enterprise environments.
