Axiom 128GB DDR5-4800 RDIMM for Cisco UCS-MR128G4RE1-AX | Enterprise Memory — UCS-MR128G4RE1-AX

Increase server memory where it matters most: capacity, stability, and deployment efficiency. This 128GB DDR5-4800 RDIMM is intended for Cisco systems that need more room for virtual machines, database caches, analytics engines, and mixed enterprise workloads. Registered ECC memory helps maintain reliable operation in environments where consistency is as important as speed. The 4,800 MHz data rate gives this module the bandwidth expected from DDR5 server memory, while the 128GB density reduces the number of modules required to reach a target capacity. That can be a meaningful advantage in platforms with limited DIMM slots or in refresh projects where future expansion must remain available. For infrastructure teams, this is a straightforward way to raise memory headroom without redesigning the server. For procurement, it offers a clear reason to choose a premium server-grade module over lower-density alternatives: fewer parts, less slot pressure, and a capacity profile suited to enterprise workloads. For operations, it supports the kind of predictable performance that keeps critical systems available.
