About the Lenovo 32GB DDR5 TruDDR5
The Lenovo 32GB DDR5 TruDDR5 RDIMM (part number 4Z57A25943) delivers enterprise-grade memory reliability for Lenovo ThinkSystem Gen 3 servers and compatible platforms. This registered DIMM module combines DDR5 speed with dual-layer error correction—both ECC and On-Die ECC (ODECC)—making it the trusted choice for mission-critical workloads where data integrity cannot be compromised.
Engineered for data center environments, the TruDDR5 operates at a low 1.1V with a 2Rx8 rank configuration, optimizing performance across a wide temperature range from 0°C to 85°C. Infrastructure teams, storage architects, and IT procurement specialists rely on Lenovo's ServerProven certification to ensure seamless integration with their existing environments. Advanced RAS (Reliability, Availability, and Serviceability) features including Post-Package Repair (PPR) and improved refresh management extend module lifespan and reduce downtime risk. With 32GB capacity per module, organizations can scale memory without excessive power draw or thermal overhead. This is ideal for virtualization, database management, and analytics platforms demanding consistent performance.
