KSM26RS4/32HCR

High-Density DDR4 ECC Registered RDIMM Capacity Expansion with the KSM26RS4/32HCR

The KSM26RS4/32HCR is a 32GB DDR4-2666 ECC Registered (RDIMM) module engineered for enterprise 2S/4S server platforms where memory integrity and predictable latency are mandatory. By using a 72-bit ECC data path and registered buffering, the KSM26RS4/32HCR supports stable population across large DIMM counts, helping maintain signal integrity under sustained CPU and I/O load.

Designed for modern Intel and AMD DDR4 generations, the KSM26RS4/32HCR increases per-socket memory headroom to reduce page faults and avoid storage-backed swapping in virtualization and database tiers. Its single-rank x4 organization aligns well with server-class memory controllers for balanced bandwidth and reliability, while JEDEC-compliant DDR4-2666 (PC4-21300R) timings provide consistent performance across validated BIOS configurations. The low-profile 288-pin form factor and 1.2V operating voltage support dense airflow-constrained chassis, and optional Intel XMP profile support can simplify platform tuning where supported.

Why Choose the KSM26RS4/32HCR?

Choosing the KSM26RS4/32HCR delivers a practical density-to-performance increase without changing CPU, storage, or PCIe topology, making it ideal for in-place upgrades and standardised fleet rollouts. The KSM26RS4/32HCR is optimised for enterprise reliability through ECC error correction and RDIMM electrical isolation, enabling scalable memory footprints that remain stable as node counts and VM density grow.

Kingston designs its Server Premier modules with a validation-first engineering philosophy, targeting long-term availability, strict component control, and compatibility with mainstream server boards and BIOS qualification processes to meet modern data centre operational standards.

Key Applications:

2S/4S DDR4 server memory upgrades
Virtualization and VDI consolidation
In-memory databases and caching tiers
Analytics and batch processing
Infrastructure services and middleware

At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your rollout and compatibility requirements, and extended warranty options up to 6 years to secure long-lived platforms built around the KSM26RS4/32HCR.
