Kingston Server Premier 64GB DDR5-5600 ECC RDIMM

The Kingston Server Premier 64GB DDR5-5600 ECC RDIMM (KSM56R46BD4PMI-64MBI) is a high-capacity registered ECC memory module engineered for the demands of current-generation server platforms. Built on DDR5 architecture, it operates at a validated speed of 5600 MT/s with a 288-pin RDIMM form factor, delivering substantially greater bandwidth and improved power efficiency compared to DDR4 predecessors. The module incorporates on-die ECC (ODECC) at the DRAM level alongside the RDIMM's traditional chipkill-capable server ECC, providing two discrete layers of data integrity protection critical for mission-critical environments.

This module is manufactured to Kingston's Server Premier specification, which means each unit is built using components sourced and validated specifically for server use rather than repurposed from consumer stock. The 64GB density is achieved through a 2Rx4 dual-rank, x4 bus width organization, utilizing a registered (buffered) clock and address interface via an RCD (Registering Clock Driver) to maintain signal integrity across high-DIMM-count memory channels. Operating voltage is 1.1V, consistent with the DDR5 standard, contributing to lower thermal output per gigabyte relative to DDR4 at equivalent densities.

The KSM56R46BD4PMI-64MBI targets enterprise deployments where memory subsystem reliability, density, and throughput are non-negotiable. It is validated against current-generation server platforms using Intel Xeon Scalable (Sapphire Rapids and successors) and AMD EPYC (Genoa and successors) processors, which natively support DDR5. The module conforms to JEDEC DDR5 standards and carries support for SPD (Serial Presence Detect) and SPD Hub as defined in the DDR5 specification, enabling accurate platform detection and configuration during server POST.

Ideal for

• High-core-count virtualization hosts running VMware vSphere or Microsoft Hyper-V, where large memory footprints are required to support dense virtual machine populations with memory overcommit headroom
• In-memory database deployments such as SAP HANA, Oracle Database In-Memory, or Redis Enterprise, where working datasets must reside entirely in RAM to meet sub-millisecond latency SLAs
• AI and machine learning inference servers that stage large model weights and batch data in system memory prior to offloading to accelerators, benefiting from DDR5's increased bandwidth
• Enterprise storage controllers and software-defined storage nodes (e.g., Ceph, IBM Spectrum Scale) that rely on large DRAM caches for metadata operations and read/write buffering
• High-performance computing (HPC) cluster nodes running memory-bandwidth-sensitive workloads such as computational fluid dynamics, genomics pipelines, or financial Monte Carlo simulations
• Mission-critical ERP and transaction processing systems requiring continuous uptime, where the dual-layer ECC architecture (ODECC plus RDIMM server ECC) reduces unplanned downtime risk from transient and hard memory errors
