Cisco UCS Compatible DDR5 RDIMM

This 32 GB registered DDR5 module runs at 4800 MT/s with CL40 latency and 1.1 V operation. It is built for Cisco UCS servers that require ECC RDIMM memory and carries part number MR38400-314K1.

288-pin registered ECC module for server boards

The 288-pin RDIMM fits DDR5 server motherboards that accept registered ECC memory. Its 1Rx4 organisation and 1.1 V voltage match the platform's electrical requirements without additional cooling.

Suited for Cisco UCS memory upgrades

Administrators expanding or replacing memory in compatible Cisco UCS systems can use this module. Builds needing unbuffered DIMMs, non-ECC memory, or a different speed grade should select another part.

Questions about this item

Will the CL40 latency become a bottleneck during sustained server workloads?

The module runs at DDR5 4800 with a CL40 timing, which is the standard latency for this speed grade and does not introduce an additional bottleneck beyond the JEDEC specification.

How much heat does a 1.1 V registered DIMM generate when running continuously?

At 1.1 V the module draws minimal power for a 32 GB DDR5 RDIMM, and without a heat spreader it relies on normal chassis airflow to stay within thermal limits during all-day operation.

Does my Cisco server need a specific BIOS revision or memory controller to accept this 1Rx4 RDIMM?

The part is validated for Cisco systems using the UCSX-MRX32G1RE1 part number, so any platform that lists that part number will accept the module without extra configuration.
