Lenovo 32GB DDR5-4800/PC5-38400 SDRAM Memory Module

The Lenovo 4X77A77031 is a 32 GB TruDDR5 memory module that expands the performance headroom of Lenovo ThinkSystem SD650 V3 Neptune DWC servers. Running at a DDR5-4800 data rate, it supplies the bandwidth required for large in-memory databases, dense virtualization, and high-performance computing tasks that push traditional memory to its limits.

Engineers and administrators who manage enterprise workloads will appreciate the module’s registered ECC design, which actively corrects memory errors to keep critical applications online and accurate. The 1.10 V operating voltage helps lower overall power consumption in the data center, an important consideration when servers run around the clock.

A dual-rank layout and 288-pin DIMM interface allow straightforward installation alongside existing TruDDR5 modules, letting teams scale capacity without complicated reconfiguration. Whether you are consolidating virtual machines, training AI models, or accelerating real-time analytics, this module delivers the stable memory foundation that modern workloads require.
