Server-grade LRDIMM for Cisco UCS C4200

This 128GB DDR4 3200 ECC Load Reduced DIMM is built for the Cisco UCS C4200 server platform. It delivers registered, error-correcting memory in a single 288-pin module running at 1.2V with CL22 latency. The 4Rx4 organisation suits dense memory configurations in enterprise workloads.

Replaces Cisco UCSML128G4RW and UCSXML128G4RW

The module directly substitutes those Cisco part numbers and drops into slots rated for 2133, 2400, 2666 or 2933 MT/s, operating at the highest common speed. The upgrade is worthwhile when the chassis demands LRDIMM topology and cannot accept unbuffered or standard registered DIMMs.

128GB capacity per module for heavy virtualization

A single stick provides substantial headroom for large VM counts, in-memory databases or analytics datasets. It reaches its limit when the C4200 memory slots are fully populated or when the application set exceeds the total addressable memory of the platform.

Questions about this item

Does the 288-pin LRDIMM fit the Cisco UCS C4200 memory slots?

Yes, the 288-pin DDR4 ECC Load Reduced DIMM is designed for the Cisco UCS C4200 server and replaces Cisco part numbers UCSML128G4RW and UCSXML128G4RW.

What is the correct installation step to avoid mixing memory types in the Cisco UCS C4200?

Install only ECC Load Reduced modules; do not mix with unbuffered or ECC Registered DIMMs, as the system requires uniform Load Reduced memory across all populated slots.

Will the 128GB module need a firmware update or battery replacement later?

No firmware update or battery is required for the DDR4 ECC LRDIMM; it operates at 1.2V with backward compatibility to 2133, 2400, 2666 and 2933 MHz speeds.
