KVR21R15D4/16 Kingston 1x16GB DDR4 RDIMM ECC RAM

High-Performance DDR4 Registered ECC RDIMM Memory Expansion with the KVR21R15D4/16

The KVR21R15D4/16 is a 16GB DDR4 Registered ECC RDIMM engineered for server platforms that require buffered memory signalling and in-line error correction under sustained load. Designed for broad JEDEC compliance at DDR4-2133, the module supports predictable latency behaviour and stable operation across mixed enterprise configurations where memory integrity directly affects uptime.

In modern 2-socket CPU platforms, RDIMM architecture reduces electrical loading on the memory controller, enabling higher population densities than unbuffered DIMMs while maintaining timing consistency. The KVR21R15D4/16 integrates 72-bit ECC data paths to mitigate soft errors during virtualization, database transactions, and storage control operations. Its low-profile mechanical design supports dense rack deployments and improved airflow in constrained chassis, while 1.2V operation aligns with power and thermal budgets in scale-out environments.

Why Choose the KVR21R15D4/16?

The KVR21R15D4/16 provides a practical density-to-performance step for enterprises expanding server memory without changing platforms, delivering RDIMM buffering, ECC resiliency, and predictable JEDEC operation in a single module. It scales cleanly in multi-DIMM configurations where validated signalling and consistent module characteristics are essential for fleet standardisation and controlled growth.

Kingston designs ValueRAM for dependable integration into enterprise servers, emphasising standards-based engineering, component traceability, and production discipline aligned with modern data centre qualification practices. This approach supports repeatable deployments and reduces variability when maintaining homogeneous memory configurations across clustered systems.
