Lenovo TruDDR5 64GB 2Rx4 PC5-38400 ECC RDIMM 4800MHz

The Lenovo TruDDR5 64GB 2Rx4 PC5-38400 ECC RDIMM (4X71N41558) is a high-capacity, registered DDR5 memory module engineered specifically for Lenovo ThinkSystem servers operating in demanding enterprise and datacenter environments. Built on the DDR5 architecture, the module operates at a native speed of 4800MHz with a rated bandwidth of 38400 MB/s, delivering a substantial throughput improvement over previous DDR4 generations. The dual-rank, quad-die (2Rx4) configuration across a 288-pin RDIMM form factor allows this 64GB module to balance capacity and signal integrity, making it well-suited for memory-intensive server platforms.

The module incorporates ECC (Error-Correcting Code) functionality, which detects and corrects single-bit memory errors in real time, safeguarding data integrity across long-duration, mission-critical workloads. As a Registered DIMM (RDIMM), it uses an on-module register to buffer command and address signals, reducing electrical load on the memory controller and enabling stable multi-DIMM-per-channel configurations in high-density server deployments. Operating voltage is 1.1V, consistent with the DDR5 standard's reduced power profile compared to DDR4, contributing to improved energy efficiency at scale.

The Lenovo TruDDR5 line is validated and tested against Lenovo's ThinkSystem server portfolio, ensuring full compatibility and optimal performance on supported platforms. This module is particularly well-positioned for AI inference and training infrastructure, large in-memory databases, virtualization hosts, and high-performance computing (HPC) clusters where aggregate memory bandwidth and per-socket capacity directly influence workload throughput and consolidation ratios.

Ideal for

• High-density virtualization hosts requiring large per-socket memory capacity to support numerous concurrent virtual machines with isolated memory allocations
• In-memory database platforms such as SAP HANA or Redis where the entire working dataset must reside in RAM to meet sub-millisecond query latency requirements
• AI and machine learning inference servers where large model weights and batch data need to be held in fast, low-latency system memory close to the CPU
• High-performance computing (HPC) nodes running simulation, computational fluid dynamics, or genomics workloads that demand sustained high memory bandwidth
• Enterprise analytics and data warehousing appliances processing large result sets entirely in memory to accelerate business intelligence query performance
• Cloud-native application servers and container orchestration nodes requiring reliable ECC-protected memory to maintain uptime and data integrity across densely packed workloads
