Cisco UCS C240 M7 DDR5 RDIMM

This NEMIX RAM module provides 128GB of DDR5 4800 registered ECC memory in a single 288-pin DIMM. It is built for the Cisco UCS C240 M7 rack server and uses a 4Rx4 organisation with CL40 latency at 1.10V. The part number MR38400-744K1 identifies the exact configuration.

Check server DIMM slots and population rules

Verify that the UCS C240 M7 has a free 288-pin DDR5 slot and consult the server documentation for approved population order. Registered ECC modules must match the platform’s qualified-vendor list so confirm this part number against Cisco’s compatibility matrix before installation. Mixed-rank or mixed-voltage configurations may prevent the system from posting.

Registered ECC build with major OEM chips

The module uses Samsung, Micron or Hynix components assembled without a heat spreader for standard server airflow. Registered signalling reduces electrical load on the memory controller while ECC corrects single-bit errors in mission-critical workloads. The 1.10V operation aligns with DDR5 baseline voltage for efficient power draw in dense configurations.

Perguntas sobre este artigo

Does the 128GB DDR5 4800 module arrive as a single stick or must I order multiple kits?

The package contains one 128GB 288-pin DDR5 RDIMM; no extra modules or accessories are included.

When should I choose the 4Rx4 CL40 1.1V variant over other DDR5 capacities?

Select this 128GB 4Rx4 registered ECC module when your Cisco UCS C240 M7 requires maximum density per slot at the standard 4800 MT/s server speed.

What does the 4800 MT/s rating deliver once the RDIMM is installed in the Cisco UCS C240 M7?

The module runs at the platform's native DDR5 4800 speed with CL40 latency, providing 128GB of registered ECC capacity per DIMM slot.
