Server memory kit

This NEMIX RAM kit delivers 1TB of DDR4 ECC LRDIMM capacity across sixteen 64GB modules. It is built for IT professionals upgrading a Dell EMC PowerEdge R7425 server that requires registered load-reduced memory.

Thermals and power

Each module operates at 1.2V with no heat spreader, relying on the server chassis airflow for cooling. The load-reduced design reduces electrical load on the memory bus, helping to keep power draw predictable under sustained workloads.

Deciding specification

The kit uses a 4Rx4 organisation with CL19 latency at 2666MHz, a combination that must match the platform memory configuration rules. Buyers whose systems require a different rank structure or latency will not be able to use this kit.

Questions about this item

How do I install the 16 modules of 288-pin DDR4 LRDIMM into the PowerEdge R7425, and what step is often missed?

Power down the server, open the chassis, populate all 16 slots following the R7425 memory population guide, then run the BIOS memory configuration utility so the 4Rx4 ranks are recognised.

What maintenance or replacement will this 1TB kit need over its service life?

The modules have no heat spreaders and are sealed; no user-serviceable parts exist. If a stick fails, replace the individual 64GB LRDIMM with an identical 2666MHz CL19 4Rx4 part.

What limit appears first when the kit runs sustained workloads at 2666MHz?

The 4Rx4 organisation and CL19 latency cap sustained throughput; the memory controller will hit rank-density bandwidth limits before thermal throttling occurs at 1.20V.
