NEMIX RAM 512GB 4x128GB DDR5 4800 CL40 ECC RDIMM Dell XR7620 memory upgrade

Dell PowerEdge XR7620 compatible kit

This 512GB DDR5 kit delivers 4800 MT/s registered ECC memory for the Dell PowerEdge XR7620 rack server. Four 128GB modules populate the required 288-pin slots with 4Rx4 organisation. The CL40 latency and 1.1V operation match the platform specification. IT teams needing maximum capacity per channel for virtualisation or database workloads can deploy this kit directly.

Thermals noise and power draw

Registered DDR5 modules run at 1.10V without integrated heat spreaders, relying on server chassis airflow for cooling. The lower voltage reduces power draw per module compared with previous DDR generations. In a populated XR7620 the memory subsystem stays within the platform thermal envelope under sustained load. No active cooling or additional fan headers are required for the memory itself.

What the kit changes

The four-module kit provides the full 512GB capacity in a single validated package, eliminating mixed-rank configurations that can limit speed. ECC and registered buffering protect data integrity for mission-critical applications. Modules are stress-tested before shipment to reduce early-life failures. The package contains only the four RDIMMs; no cables, software or additional hardware are included.
