Lenovo TruDDR5 32GB 2Rx8 PC5-38400 ECC RDIMM 4800MHz

The Lenovo TruDDR5 32GB 2Rx8 PC5-38400 ECC RDIMM (4X71N41557) is a registered DDR5 memory module engineered to Lenovo's strict quality and compatibility standards for ThinkSystem server platforms. Operating at 4800MHz with a PC5-38400 bus speed, it delivers significantly higher bandwidth and improved power efficiency compared to DDR4 generations, leveraging the on-die ECC and improved signal integrity architecture native to DDR5. The dual-rank (2Rx8) x8 configuration balances density and channel population flexibility, making it well-suited for maximizing memory capacity across multi-socket server deployments.

As a Registered DIMM (RDIMM), the module incorporates a register component that buffers the command and address signals between the memory controller and the DRAM chips, reducing electrical load and enabling stable operation in high-capacity, multi-DIMM-per-channel configurations. The ECC (Error Correcting Code) functionality actively detects and corrects single-bit memory errors and detects multi-bit errors, providing the data integrity required for mission-critical enterprise environments. Running at 1.1V, DDR5 RDIMMs deliver meaningful reductions in per-module power consumption relative to DDR4 counterparts operating at similar capacities.

Designed and validated specifically for Lenovo ThinkSystem servers, TruDDR5 modules undergo Lenovo's qualification process to ensure interoperability, firmware compatibility, and optimal performance within supported platforms. This makes the 4X71N41557 a reliable choice for enterprises building or expanding datacenter infrastructure supporting AI inference and training pipelines, large in-memory databases, high-performance computing clusters, and virtualization environments where memory bandwidth, capacity, and integrity are critical operational requirements.

Ideal for

• High-density VMware or KVM virtualization hosts requiring large aggregate memory capacity with per-VM memory isolation and reliability
• AI and machine learning inference servers where DDR5 bandwidth improvements accelerate data movement between CPU and accelerator subsystems
• In-memory database platforms such as SAP HANA or Redis where working datasets must reside entirely in RAM for low-latency query performance
• High-performance computing (HPC) clusters running simulation, computational fluid dynamics, or financial modeling workloads demanding sustained memory throughput
• Enterprise application servers running ERP, CRM, or analytics workloads that benefit from ECC-protected memory to ensure transactional data integrity
• Cloud service provider infrastructure scaling out Lenovo ThinkSystem-based nodes where standardized, validated memory modules simplify procurement and lifecycle management
