Description
The M393A2G40DB0-CPB is a high-performance 16GB DDR4-2133MHz ECC Registered DIMM (RDIMM) that serves as a critical memory upgrade for various Cisco UCS server platforms. This enterprise-grade memory module is specifically engineered to ensure maximum reliability and data integrity through its Error Correcting Code technology, which automatically detects and fixes common data corruption. Designed for demanding virtualization and database environments, this module offers the stability required for continuous, high-uptime operations in mission-critical data centers. When integrated into Cisco UCS rack or blade servers, it provides the necessary bandwidth to optimize system throughput and overall processing efficiency.
This pre-owned memory module features a dual-rank architecture and operates at a low voltage of 1.2V, contributing to reduced power consumption and lower thermal output within your server chassis. Each unit undergoes rigorous testing to ensure it meets the strict performance standards expected by IT professionals managing legacy or current Cisco infrastructure. The RDIMM format includes a register that buffers the command and address signals, allowing for greater memory density and improved signal stability in multi-DIMM configurations. Choosing this certified hardware is a cost-effective strategy for expanding your server’s memory capacity without compromising on the quality or compatibility inherent to the Cisco ecosystem.
