Dell PowerEdge R7425 512GB memory kit

This NEMIX RAM kit delivers 512GB of DDR4 2666 ECC LRDIMM memory across eight 64GB modules. It is built for the Dell EMC PowerEdge R7425 server and runs at 1.2V with CL19 latency. The load-reduced design helps the memory controller manage high-density DIMMs in dense virtualisation hosts.

Suited for IT teams scaling a single R7425

Administrators who need maximum capacity in one chassis will use all eight slots. Buyers who want more storage or who run platforms that only accept standard RDIMM modules cannot use this kit. The 4Rx4 organisation also requires a motherboard qualified for load-reduced DIMMs.

512GB total capacity in eight 64GB LRDIMM modules

This aggregate figure is the single limit that decides whether the upgrade fits the workload. If the application set demands less than the full 512GB, a smaller kit avoids unused slots and leaves room for future expansion.

Questions about this item

How do I confirm the 512GB kit is running at DDR4 2666 with ECC after installation?

Enter the server BIOS or use a tool like dmidecode to verify each 64GB module shows 2666 MT/s, CL19, 1.20 V, 4Rx4 organisation and ECC enabled.

What ships in the box and is anything else required for the PowerEdge R7425?

The box contains eight 64GB 288-pin DDR4 LRDIMM modules (part ML21300-944K8); no extra cables, brackets or licences are needed for the R7425.

Why choose the 8 x 64GB LRDIMM kit instead of smaller RDIMM options?

LRDIMM reduces electrical load on the memory bus, allowing all 512GB to run at the full 2666 speed supported by the R7425, whereas RDIMM would limit capacity or speed.
