The Cisco 128GB DDR5-4800 RDIMM 4Rx4 (16Gb), part number UCSX-MR128G4RE1, is a registered DDR5 memory module from Cisco. It provides 128 GB of capacity in a single module and operates at 4800 MHz.
The module uses a quad-rank, x4 (4Rx4) configuration based on 16Gb DRAM. As a registered DIMM (RDIMM), it includes a register between the memory controller and the DRAM, a design used in server platforms to support higher memory capacities per system.
This type of high-capacity DDR5 RDIMM is typically installed in data centre servers to increase available system memory for memory-intensive workloads such as virtualisation, databases and large-scale applications. Organisations planning memory expansion or new server builds can reference the Cisco part number UCSX-MR128G4RE1 when specifying this module.
