NEMIX RAM 512GB (4x128GB) DDR5 4800 PC5-38400 CL40 4Rx4 1.1V ECC RDIMM Dell R860

Server Memory Kit for Dell PowerEdge R860

This 512GB kit contains four 128GB DDR5 RDIMMs built for the Dell PowerEdge R860 rack server. The modules are ECC registered with a 4Rx4 organisation, targeting enterprise workloads that require maximum capacity and data integrity. IT teams upgrading memory in this specific platform can deploy the kit without configuration changes.

Thermals and Power in Normal Operation

Each module runs at 1.10V, the standard DDR5 voltage, keeping power draw predictable under sustained load. The registered design adds a clock cycle of buffering, which stabilises signalling on heavily populated channels. No heat spreaders are fitted, so airflow through the server chassis handles thermal management.

Compatibility and Validation

The part number MR38400-744K4 identifies a configuration validated for the Dell PowerEdge R860, removing guesswork from qualification testing. Modules use major OEM DRAM from Samsung, Micron or Hynix and are stress tested under load before shipment. Builders needing different capacities, speeds or form factors must select a separate kit.
