The UCS-ML-1X644RU-G from Cisco is a specialized DDR4 2133 module designed for compatibility with Cisco's Unified Computing Systems (UCS). With a large 64GB capacity and leveraging LRDIMM (Load-Reduced DIMM) technology along with a configuration of 8Gx72 4DRx4, this module is tailored for environments where maximum memory capacity and bandwidth are critical. Operating under the DDR4-2133P specification and adhering to the PC4-17000 standard, it not only offers high-speed data transfer rates but also ensures robust performance in server and data center environments. The module's 288pin interface and advanced manufacturing technology, indicated by its [4Gx4 36C] designation, enable it to deliver on the reliability and performance Cisco's systems are known for. This memory module is an essential component for expanding the capabilities of Cisco Unified Computing Systems, particularly in applications requiring extensive data processing and storage.
