KSM26RS4/16HDI Kingston 1x16GB DDR4 RDIMM ECC RAM

Enterprise DDR4 Registered ECC Server Memory Module optimised for platform stability with the KSM26RS4/16HDI

The KSM26RS4/16HDI is a Kingston Server Premier DDR4-2666 Registered ECC RDIMM designed for Intel Xeon and AMD EPYC server platforms where memory integrity and predictable latency are mandatory. By using a registered signal path and 72-bit ECC data width, the KSM26RS4/16HDI reduces electrical loading on the memory channel, enabling stable operation as DIMM population increases across multi-socket boards.

Architecturally, the KSM26RS4/16HDI supports balanced compute nodes that depend on sustained memory bandwidth for virtualization consolidation, database buffering, and scale-up workloads. Its single-rank x4 organisation aligns with enterprise RAS goals, while the low-profile 288-pin form factor improves mechanical clearance in dense 1U/2U chassis and maintains airflow around CPU heatsinks. Deployed alongside PCIe expansion and NVMe storage tiers, the KSM26RS4/16HDI helps preserve end-to-end performance by minimising memory-related stalls under mixed I/O and compute pressure.

Why Choose the KSM26RS4/16HDI?

The KSM26RS4/16HDI is selected when operational consistency matters more than headline peak clocks, providing a robust density-to-performance balance at DDR4-2666 for enterprise server fleets. With Registered ECC behaviour suited to higher DIMM counts, the KSM26RS4/16HDI supports scalable capacity planning, simplifies standardised node builds, and reinforces uptime objectives in production clusters and private cloud hosts.

Kingston designs Server Premier memory with a validation-first engineering approach focused on JEDEC compliance, controlled component selection, and repeatable compatibility across server-class chipsets and motherboards. This discipline aligns with modern data centre requirements for lifecycle consistency, predictable qualification, and deployment at scale.

Key Applications:

• Server memory upgrade and expansion
• Virtualization and private cloud hosts
• Database and in-memory caching
• Scale-up compute nodes
