Cisco Server Memory Upgrade
This 128GB DDR5 RDIMM is built for Cisco UCS servers that require registered ECC memory. The single-module design adds high-density capacity in one slot, simplifying upgrades for IT teams managing dense virtualization or database workloads.
Sustained Load Behaviour
ECC and registered buffering protect data integrity during continuous operation, while the 4Rx4 organisation spreads accesses across four ranks to keep throughput steady under heavy multi-threaded demand. The module runs at 4800MHz with CL40 latency, delivering predictable bandwidth for long-running server tasks.
Thermals, Noise and Power
Operating at 1.1V, the module draws minimal power and generates little heat without a heat spreader. Passive cooling in a properly ventilated chassis keeps temperatures low, and the lack of moving parts means the upgrade adds no audible noise to the rack environment.

Frågor om den här produkten
How much power does this 128GB DDR5 4800 CL40 registered module draw at its rated 1.1V voltage during continuous operation?
The module operates at 1.1V, the standard DDR5 voltage, so power draw scales with the 128GB capacity and 4800 MT/s data rate; exact watts depend on workload and server memory-controller tuning.
What server platform must I already own for this Cisco MR38400-744K1 288-pin RDIMM to be recognised and initialised?
It is validated for Cisco UCS servers that list the MR38400-744K1 part number; the platform must support DDR5 4800 registered ECC memory with 4Rx4 organisation.
Will this 4Rx4 DDR5 4800 CL40 RDIMM operate in the same Cisco UCS chassis alongside existing 2Rx4 or 1Rx4 DDR5 4800 modules?
Yes — Cisco UCS memory controllers support mixed-rank populations at the same speed; the system will run all slots at 4800 MT/s CL40 provided the total rank count per channel stays within the platform limit.
