Lenovo 4X77A08633 32GB RDIMM Server Memory Module
Overview
The Lenovo 4X77A08633 is a 32GB Registered Dual In-line Memory Module (RDIMM) operating at 3200MHz with a 2RX4 configuration and 1.2V voltage. This module is designed to expand the memory capacity of compatible Lenovo servers, enabling improved performance for memory-intensive applications such as virtualization, large databases, and high-performance computing environments. Its specific configuration is critical for maintaining system stability and achieving optimal throughput in enterprise data centers.
Compatibility
This 4X77A08633 RDIMM is engineered for specific Lenovo ThinkSystem servers. It is compatible with systems requiring DDR4 3200MHz RDIMM memory, including but not limited to select models within the ThinkSystem SR500, SR600, SR800, ST500, and ST600 series. Always consult your server's hardware maintenance manual or Lenovo's official compatibility matrix to confirm support for this specific memory part number before installation.
Installation Notes
Installation requires opening the server chassis and inserting the RDIMM into a designated memory slot. Ensure the system is powered off and grounded to prevent electrostatic discharge. The module features a notch for correct orientation and should be seated firmly until the retention clips engage. Refer to the server's documentation for specific slot population guidelines to achieve dual-channel or quad-channel configurations for maximum bandwidth.
