About the Lenovo TruDDR4 128GB 4Rx4 PC4-25600 ECC LRDIMM 3200MHz
A single Lenovo TruDDR4 128GB 4Rx4 PC4-25600 ECC LRDIMM 3200MHz module (part number 4X77A77498) establishes the memory ceiling for enterprise servers demanding maximum density and reliability in a single slot. This 128GB capacity represents the density tier chosen by organizations building large-scale virtualization, database, and analytics platforms where per-socket memory maximization directly impacts workload consolidation and cost efficiency.
IT procurement teams and infrastructure architects select Lenovo TruDDR4 memory when deploying systems built on Lenovo ThinkSystem Gen 2 and Gen 3 server platforms that require load-reduced buffering, ECC error correction with ChipKill support, and the performance characteristics of DDR4 running at 3200MHz with PC4-25600 rating. The quad-rank 4Rx4 configuration, 1.2V operating voltage, and CL22 latency profile deliver the balance between capacity and stability that mission-critical deployments demand, while the 288-pin DIMM form factor and 0°C to 85°C operating range ensure compatibility with Lenovo's certified server ecosystems. Load-reduced DIMM technology isolates electrical stress on the memory bus, extending module lifespan and supporting higher-density population across multiple DIMM slots within supported platforms.
Whether you are refreshing existing Lenovo infrastructure or designing new memory configurations for large-scale enterprise deployments, the 4X77A77498 module delivers the certified performance and error-correction assurance required by production environments.
