KSM48R40BD4-64HA Kingston 1x64GB DDR5 RAM

High-Density DDR5 RDIMM Server Memory featuring Registered ECC architecture with the KSM48R40BD4-64HA

KSM48R40BD4-64HA is a 64GB DDR5-4800 Registered ECC RDIMM designed for DDR5-capable rack servers and blade platforms where predictable latency and memory stability are primary design constraints. As CPU platforms move to higher core counts and wider memory channels, KSM48R40BD4-64HA supports scaling per-socket capacity without sacrificing signal integrity, enabling tighter VM-to-core ratios and more consistent QoS under mixed workloads.

By deploying KSM48R40BD4-64HA in dual-rank, low-profile form factor configurations, systems engineers can expand memory headroom while maintaining airflow and mechanical clearance in dense chassis. The registered DIMM architecture improves electrical loading characteristics across populated channels, which is critical for maintaining DDR5-4800 operation at scale. For PCIe Gen5 expansion and NVMe-centric storage tiers, KSM48R40BD4-64HA helps keep CPU cycles aligned to data access patterns by reducing memory pressure that otherwise drives paging, cache thrashing, or I/O amplification.

Why Choose the KSM48R40BD4-64HA?

KSM48R40BD4-64HA provides a practical density-to-performance balance for enterprise deployments that need repeatable behavior under 24/7 operation. It is optimized for scalable node designs where incremental memory growth per server improves consolidation efficiency, reduces per-VM overhead, and supports consistent service levels across clustered compute pools.

Kingston designs server memory with an engineering focus on compatibility validation, controlled component selection, and operational reliability aligned to modern data centre standards. KSM48R40BD4-64HA adheres to RoHS requirements and is built to integrate cleanly into managed lifecycle processes for enterprise platforms.
