About the Lenovo TruDDR4 32GB 2Rx4 PC4-25600 ECC RDIMM 3200MHz

The Lenovo TruDDR4 32GB 2Rx4 PC4-25600 ECC RDIMM (Part No. 4X77A77494) is a registered ECC DDR4 memory module engineered specifically for Lenovo ThinkSystem servers. Operating at 3200MHz with a dual-rank, quad-die architecture (2Rx4), the module delivers a balance of high capacity and memory bandwidth suited to demanding server environments. The PC4-25600 designation reflects a peak transfer rate of 25,600 MB/s, while the registered (buffered) design offloads electrical load from the memory controller, enabling higher DIMM populations per channel without signal integrity compromise.

As a Lenovo TruDDR4 module, this RDIMM is validated and qualified through Lenovo's full system-level testing process for ThinkSystem platforms, ensuring interoperability, firmware compatibility, and stable operation across supported server generations including ThinkSystem SR series and ST series rack and tower servers. Error-Correcting Code (ECC) functionality continuously detects and corrects single-bit memory errors in real time, providing the data integrity required for enterprise-grade workloads where silent data corruption is unacceptable.

With a 32GB density per module and support for multi-DIMM configurations, this memory is well-suited to memory-intensive workloads such as in-memory databases, AI/ML inference, large-scale virtualization, and enterprise application servers. Its registered buffered design and ECC protection make it a dependable building block for datacenter infrastructure serving UAE, GCC, EMEA, and APAC enterprise environments.

Ideal for

  • Scale-out virtualization hosts requiring high per-socket memory capacity with multiple concurrent virtual machines per node
  • In-memory database deployments such as SAP HANA or Redis where large working sets must reside entirely in RAM
  • AI and machine learning inference servers demanding high-bandwidth, high-capacity memory for model loading and batch processing
  • Enterprise application servers running ERP and CRM platforms where ECC protection ensures transactional data integrity
  • High-performance computing (HPC) nodes and simulation workloads that require sustained memory throughput at DDR4-3200 speeds
  • Datacenter server refreshes and capacity expansions on existing Lenovo ThinkSystem SR and ST series infrastructure
