KSM48R40BD4-64MD Kingston 1x64GB DDR5 RDIMM ECC RAM

High-Density DDR5 RDIMM Server Memory Module Optimised for Enterprise Platforms with the KSM48R40BD4-64MD

The KSM48R40BD4-64MD is a 64GB DDR5 RDIMM engineered for current-generation server CPUs that rely on registered DIMM architectures to sustain high memory channel loading and stable operation at scale. In dual-socket rack servers and dense virtualization nodes, the KSM48R40BD4-64MD supports predictable memory behaviour through ECC protection and a 72-bit registered design, enabling higher capacity per channel without compromising signal integrity.

Built to the DDR5-4800 JEDEC speed grade, the KSM48R40BD4-64MD aligns memory throughput with PCIe 4.0/5.0 era platforms where accelerator, NVMe, and high-speed networking expansion can otherwise be constrained by memory bandwidth and latency. Its 288-pin low-profile form factor is optimized for thermally managed server layouts, supporting clean airflow paths around CPU heatsinks and storage backplanes while scaling memory footprints for database tiers and in-memory caching where capacity is the primary architectural lever.

Why Choose the KSM48R40BD4-64MD?

The KSM48R40BD4-64MD provides an efficient density-to-performance profile for enterprise deployments that must standardize on DDR5 RDIMM across fleets. It enables scalable configuration planning—expanding nodes in measured increments—while maintaining reliability through registered buffering and ECC, making it suitable for long-lived clusters and controlled change windows in private cloud environments.

Kingston designs server memory with a focus on consistent electrical margins, standards compliance, and compatibility validation for modern data centre platforms. This engineering approach supports operational stability, predictable lifecycle management, and alignment with enterprise procurement requirements for compliant, RoHS-ready components.

Key Applications:

• Server virtualization and private cloud nodes
• Database servers
• In-memory caching tiers
• General-purpose rack server memory expansion
