KF556R36RBK4-64

High-Performance DDR5 RDIMM ECC Server Memory Kit optimised for channel-balanced scaling with the KF556R36RBK4-64

KF556R36RBK4-64 is a 64GB DDR5 Registered ECC memory kit designed to increase usable memory capacity and stability in enterprise server and workstation platforms where CPU core counts and VM density stress the memory subsystem. By using RDIMM buffering, the kit supports higher electrical loading per channel, enabling consistent performance as you populate more DIMM slots on modern multi-core CPU generations.

Architecturally, KF556R36RBK4-64 aligns with DDR5’s improved bank structure and bandwidth scaling to support PCIe Gen4/Gen5 I/O-heavy configurations, where fast storage and accelerator expansion can expose memory latency and contention. The 4x16GB layout enables balanced population across channels for predictable NUMA behavior, while ECC protection safeguards in-memory datasets for virtualization, database, and analytics workloads. Operating at the DDR5-5600 speed class, KF556R36RBK4-64 targets stable throughput for mixed read/write server profiles without compromising reliability under sustained load.

Why Choose the KF556R36RBK4-64?

KF556R36RBK4-64 delivers a pragmatic density-to-performance profile for IT teams refreshing server fleets, adding capacity to virtualization hosts, or standardizing memory configurations across nodes. The registered design improves signal integrity at scale, ECC reduces risk of silent data corruption, and the 4-DIMM kit format simplifies consistent channel population for repeatable deployment outcomes and future expansion planning.

Kingston engineers memory for long-term platform compatibility and controlled operating parameters, focusing on reliability, validation discipline, and alignment with modern data centre standards for continuous operation and predictable lifecycle management.

Key Applications:

Enterprise server memory expansion and refresh
Virtualization hosts and VDI clusters
Database and in-memory caching tiers
Analytics and ETL processing
HPC pre-processing and simulation nodes
