Cisco UCS DDR5 RDIMM upgrade

This 64GB DDR5 module is built for Cisco UCS servers that require registered ECC memory. It targets administrators who need to expand capacity in validated platforms without mixing unqualified DIMMs. The single-stick design lets you populate one slot at a time.

288-pin registered ECC integration

The 288-pin RDIMM plugs directly into compatible Cisco DDR5 server boards and operates at 1.10V. Registered signalling reduces electrical load on the memory controller, freeing headroom for larger configurations. ECC protection corrects single-bit errors to maintain data integrity under sustained workloads.

64GB capacity at 4800 MT/s

One module delivers 64GB of PC5-38400 bandwidth with CL40 latency and a 2Rx4 organisation. It comfortably handles virtualisation, database and container workloads that benefit from high density. Systems needing more total memory must add further qualified DIMMs to reach the platform limit.

Highlights

  • 64 GB capacity supports heavy virtualization workloads
  • DDR5 4800 speed delivers high memory bandwidth
  • CL40 latency ensures responsive server operation
  • ECC registered design protects data integrity
  • 1 V operation reduces power consumption

Questions about this item

Does the CL40 latency limit throughput when the module runs at 4800 MT/s continuously?

The module operates at DDR5 4800 with CL40 timing; latency is fixed at that specification and does not change under sustained load.

How much heat does the 1.1 V registered DIMM produce during all-day server workloads?

The RDIMM runs at 1.10 V without a heat spreader; registered buffering reduces electrical load on the memory controller, keeping thermals within standard server limits.

Which Cisco UCS platforms accept this 288-pin 2Rx4 ECC RDIMM without additional parts?

The module is built to match Cisco part MRX64G2RE1 and fits any UCS server qualified for 64 GB DDR5 4800 registered ECC memory.
