KF556R28RBE-16 Kingston 1x16GB DDR5 RDIMM ECC RAM

High-Performance DDR5 ECC RDIMM server memory engineered for stable compute density with the KF556R28RBE-16

KF556R28RBE-16 is a 16GB DDR5 Registered ECC RDIMM designed for modern server and workstation platforms where memory integrity, deterministic latency, and capacity scaling are mandatory. As an RDIMM, it supports higher population counts than unbuffered DIMMs, enabling balanced channel utilization on current Intel Xeon and AMD EPYC generations for virtualization hosts and general-purpose compute nodes.

With DDR5-5600 operation and tight CL28 timing, KF556R28RBE-16 helps maintain predictable throughput for CPU-bound workloads and mixed I/O profiles. DDR5 architecture improves bank-level parallelism and efficiency, which is critical when PCIe Gen5 expansion and NVMe storage tiers increase memory pressure through higher queue depths and larger working sets. The registered, ECC-protected datapath reduces soft-error risk in long-running services, while low-profile mechanical design supports dense 1U/2U chassis and airflow-focused layouts.

Why Choose the KF556R28RBE-16?

KF556R28RBE-16 is selected when infrastructure teams need a consistent, scalable memory building block that preserves platform stability under high DIMM population and sustained utilization. It aligns with capacity planning models for clustered deployments, where repeatable performance per node and ECC protection directly support uptime targets and operational predictability.

Kingston applies disciplined validation and component selection to deliver enterprise-aligned reliability, focusing on interoperability with current data centre standards, controlled manufacturing processes, and traceable quality to support fleet-level deployment and lifecycle management.
