Kingston 128GB DDR5-4800 Load Reduced DIMM Server Memory

The Kingston 128GB DDR5-4800 Load Reduced DIMM (KSM48LQ46BD8PMI-128HMR) is a high-capacity server memory module engineered for modern enterprise platforms requiring maximum memory density per channel. Built on the DDR5 architecture, it operates at a native speed of 4800 MT/s with a 288-pin LRDIMM form factor, featuring an on-module data buffer (LRDIMM DB) that isolates the host controller from the full electrical load of the DRAM devices — enabling higher DIMM population per channel without compromising signal integrity or operating frequency.

This module implements ECC (Error Correcting Code) with advanced on-die ECC at the DRAM level, combined with the system-level ECC correction inherent to registered/load-reduced architectures, delivering layered data integrity suitable for mission-critical and continuously operating environments. The quad-rank x4 (4Rx4) configuration maximizes storage density on a single DIMM, supporting configurations that scale aggregate system memory into the multi-terabyte range on platforms with sufficient slot capacity. Operating voltage is 1.1V, consistent with DDR5 platform standards, contributing to improved power efficiency relative to previous-generation DDR4 LRDIMMs at comparable densities.

Designed for deployment in dual-socket and multi-socket server platforms from Intel (Sapphire Rapids and later Xeon Scalable generations) and AMD EPYC ecosystems supporting DDR5 LRDIMM, this module is suited to memory-intensive enterprise workloads including in-memory databases, large-scale AI/ML model training and inference, virtualized infrastructure, and high-performance computing environments. Kingston's server-grade manufacturing process includes 100% factory testing and adherence to JEDEC DDR5 LRDIMM specifications.

Ideal for

• Large-scale AI and machine learning training workloads requiring high memory bandwidth and maximum per-server DRAM capacity for model parameter storage
• In-memory database platforms such as SAP HANA or Oracle In-Memory where aggregate system memory directly impacts dataset residency and query performance
• High-density server virtualization environments running large numbers of concurrent VMs, where per-socket memory capacity determines consolidation ratios
• High-performance computing (HPC) clusters processing large scientific datasets or simulation workloads that benefit from quad-rank LRDIMM density scaling
• Enterprise storage appliances and caching tiers requiring substantial DRAM for metadata management and read/write buffering at scale
• Datacenter infrastructure refreshes targeting DDR5 platforms where maximizing memory per channel slot reduces total server count and rack footprint
