The Cisco UCS 128GB DDR5 ECC RDIMM, part number UCSX-MR128G4RE1-RF, is a refurbished server memory module from Cisco's UCS product line. It provides 128GB of DDR5 memory in a registered DIMM (RDIMM) form factor, with ECC (error-correcting code) support.
ECC memory detects and corrects single-bit errors as data is processed, which helps maintain data integrity during sustained operation. The registered design buffers signals between the memory controller and the DRAM, a common approach in server platforms where multiple high-capacity modules are installed.
This module is intended for Cisco UCS server environments where large memory capacity is needed, such as virtualisation hosts, database servers and other memory-intensive data centre workloads. As a refurbished part, it offers an option for expanding or maintaining existing UCS infrastructure.
