256GB DDR4 ECC RDIMM kit for Dell PowerEdge

This NEMIX RAM kit delivers 256GB of DDR4 3200 registered ECC memory across sixteen 16GB modules. It is built for Dell EMC PowerEdge XE7100, XE7420 and XE7440 rack servers that require registered DIMMs with error correction.

2Rx8 registered modules at 1.2V

Each module uses a 2Rx8 organisation and runs at 1.2V with CL22 latency. The registered design reduces electrical load on the server memory controller, while the 288-pin DDR4 form factor fits the approved Dell slots without a heat spreader.

Replaces smaller or slower DDR4 RDIMM sets

The upgrade is worthwhile when the workload demands the full 256GB capacity at 3200MT/s and the server's qualified vendor list includes this part number. It is not for systems that need unbuffered memory, non-ECC modules or a different DDR generation.

Questions about this item

What does the PC4-25600 rating on this DDR4 3200 kit indicate for bandwidth?

The PC4-25600 designation corresponds to the DDR4 3200 speed grade, specifying the peak data transfer rate for the memory modules.

What physical slot and module height clearance do these 288-pin RDIMMs need in the PowerEdge XE7100, XE7420, or XE7440?

Each 16 GB module uses a standard 288-pin DDR4 RDIMM form factor and requires a registered DIMM slot; verify chassis clearance for heat-spreader-less modules.

How should the 16 modules be populated across the CPU sockets, and which step is often missed?

Follow the Dell EMC memory population guide for 2Rx8 registered DIMMs: balance channels per processor, apply 1.20 V setting, and run the system memory test after install.
