Description

Lenovo 4X77A08632 16GB DDR4 RDIMM

Overview

The Lenovo 4X77A08632 is a 16GB DDR4 Registered DIMM (RDIMM) module designed for enterprise server environments. Operating at 3200MHz with a low voltage of 1.2V, this module provides enhanced memory bandwidth and efficiency, crucial for demanding workloads like video analytics, large database operations, or high-density surveillance recording. Its 2Rx8 configuration (dual rank, 8 bits per rank) offers improved performance characteristics over single-rank modules in certain server architectures.

Compatibility

This 16GB RDIMM is engineered for compatibility with specific Lenovo ThinkSystem servers. It is designed to work with systems that support DDR4 3200MHz RDIMM memory, including but not limited to: ThinkSystem SR635, SR655, ST650 V2, and SN550 V2. Always verify your server's specific memory configuration and maximum supported capacity before installation to ensure optimal performance and stability.

Installation Notes

As a Registered DIMM (RDIMM), this module includes an onboard buffer chip that reduces electrical load on the memory controller, enabling higher densities and improved stability in multi-module configurations. Installation requires adherence to standard server memory module handling procedures, including proper grounding and seating within the designated DIMM slots. Ensure the server is powered off and disconnected from the power source before proceeding with installation.
