KSM26RS4/16MRR

High-Performance DDR4 RDIMM Server Memory featuring ECC Registered reliability with the KSM26RS4/16MRR

The KSM26RS4/16MRR is a 16GB DDR4-2666 ECC Registered RDIMM engineered to stabilize memory behavior in enterprise server platforms where CPU core counts and virtual machine density intensify memory signaling demands. By using registered buffering, the KSM26RS4/16MRR helps maintain electrical integrity across populated DIMM channels, supporting consistent throughput and predictable latency for multi-socket systems.

Designed for DDR4 RDIMM infrastructures, the KSM26RS4/16MRR aligns with mainstream server CPU generations that rely on JEDEC-standard memory profiles for interoperability and deterministic performance. ECC protection provides in-line error correction for long-running workloads, while the low-profile 288-pin form factor supports dense chassis layouts where PCIe expansion, accelerators, and front-storage backplanes restrict airflow and mechanical clearance. This makes the KSM26RS4/16MRR a practical upgrade path for scaling capacity without disrupting PCIe lane planning, NVMe/SATA storage tiers, or serviceability goals in rack and edge deployments.

Why Choose the KSM26RS4/16MRR?

The KSM26RS4/16MRR delivers an enterprise-focused balance of capacity, signal stability, and operational resilience for DDR4 RDIMM servers, enabling higher consolidation ratios with controlled risk. Its registered architecture supports scalable DIMM population strategies, and its standardized DDR4-2666 profile simplifies qualification across mixed server fleets where repeatable rollouts and uptime targets are non-negotiable.

Kingston designs its Server Premier memory with an engineering emphasis on platform compatibility, controlled component selection, and production consistency to meet modern data centre requirements for reliability, traceability, and predictable lifecycle management.

Key Applications:

Server memory expansion for DDR4 RDIMM platforms
Virtualization and private cloud hosts
Database and infrastructure services
Edge and branch office servers
