KF556R28RBE2K4-128

High-Density DDR5 RDIMM Server Memory Kit engineered for low-latency ECC performance with the KF556R28RBE2K4-128

The KF556R28RBE2K4-128 is a 128GB DDR5 Registered ECC RDIMM kit designed to stabilise memory-heavy server platforms where predictable latency and error containment matter. Deployed across current Intel Xeon and AMD EPYC generations, the registered 72-bit ECC architecture reduces electrical loading on the memory bus, supporting higher population levels and cleaner signal integrity in dense 1U/2U nodes.

With DDR5-5600 operation, tight CL28-34-34 timings, and dual-rank 32GB modules, the KF556R28RBE2K4-128 aligns with consolidation hosts and analytics systems that are constrained by memory bandwidth and page churn rather than raw CPU cores. The low-profile 288-pin DIMM design improves airflow clearance around high-TDP CPUs and PCIe Gen5 expansion, while capacity-per-socket planning remains straightforward for NVMe-centric storage tiers and balanced NUMA layouts.

Why Choose the KF556R28RBE2K4-128?

Choosing the KF556R28RBE2K4-128 provides an enterprise-ready path to higher VM density and larger in-memory working sets without compromising platform reliability. The ECC RDIMM design supports scalable channel population for consistent performance under mixed read/write pressure, helping standardise builds across clusters and simplifying qualification for long-lived server refresh cycles.

Kingston engineers its server memory with a qualification-first approach, focusing on compatibility, controlled component selection, and repeatable manufacturing processes. This supports dependable operation in modern data centres where thermal margins, uptime targets, and validated firmware/BIOS configurations define operational standards.

Key Applications:

Server virtualization and consolidation
In-memory databases
Analytics and caching tiers
