KF556R36RB-16 Kingston 1x16GB DDR5 RDIMM ECC RAM

High-Performance DDR5 Registered Server Memory engineered for predictable latency with the KF556R36RB-16

KF556R36RB-16 is a 16GB DDR5 RDIMM designed for DDR5 registered DIMM-capable server platforms where signal integrity, timing stability, and controlled scaling matter more than consumer overclocking behavior. As a 288-pin, low-profile module, it supports clean mechanical fitment across dense rack nodes and standardized airflow paths, enabling straightforward memory expansion during refresh cycles.

Built on a DDR5-5600 (PC5-44800R) speed grade, KF556R36RB-16 aligns with current-generation CPU memory controllers that benefit from higher transfer rates while retaining registered buffering to improve electrical loading as channel population increases. The single-rank x8 organization and 72-bit data width support server-class reliability requirements, including ECC pathways, and help maintain consistent performance under virtualization and general compute consolidation. For platforms exposing PCIe Gen5 expansion and high-throughput NVMe storage fabrics, KF556R36RB-16 complements the overall I/O architecture by reducing memory stalls that can bottleneck parallel storage and networking queues.

Why Choose the KF556R36RB-16?

KF556R36RB-16 delivers a pragmatic density-to-performance step for enterprises standardizing on DDR5 RDIMM nodes, enabling predictable scaling per socket without destabilizing timing margins as memory channels are populated. Its registered architecture and server-oriented electrical profile support reliable operation in scale-out clusters where repeatability across nodes is essential for capacity planning and workload scheduling.

Kingston applies an engineering approach focused on validation, component consistency, and compatibility with modern data centre platform requirements, prioritizing operational stability across long service windows and controlled refresh cycles.

Key Applications:

• Virtualization hosts
• General-purpose compute nodes
• Scale-out clusters
• Server memory expansion and refresh
