The LENOVO ThinkSystem 64GB TruDDR4 RDIMM (Part No. 4X77A08635) is a high-performance, server-grade memory module engineered for Lenovo ThinkSystem and ThinkAgile servers including the SR630 V2, SR650 V2, and ST650 V2 platforms. Featuring a large 64 GB capacity, it leverages DDR4-3200 MHz speed (PC4-25600) to deliver superior bandwidth for memory-intensive server workloads.

This module uses a 2Rx4 (dual-rank, x4) DRAM organization and operates at an efficient 1.2V with ECC support, ensuring enhanced data integrity and fault tolerance essential in mission-critical environments. As a registered DIMM (RDIMM) with 288 pins, it is designed to reduce electrical load on the memory controller, enhancing stability and scalability in multi-module configurations.

Crafted from industry-leading DRAM components and extensively validated on Lenovo server platforms, this TruDDR4 memory module meets rigorous demands for reliability and compatibility. It boosts server performance by reducing system-level memory errors and optimizing throughput, making it ideal for data centers and enterprises aiming for increased compute efficiency and uptime.
