Dell XE9640 1 TB DDR5 RDIMM kit

This NEMIX RAM kit supplies 1 TB of DDR5 memory in sixteen 64 GB registered ECC modules built for the Dell PowerEdge XE9640. Each module runs at 4800 MT/s with CL40 latency at 1.1 V using 288-pin RDIMM form factor. The 2Rx4 organisation and major-brand Samsung, Micron or Hynix chips target enterprise server workloads that demand error correction and registered buffering.

Suited for XE9640 capacity expansion

IT teams scaling a Dell PowerEdge XE9640 to its maximum supported memory will use this sixteen-module kit to fill every slot with 64 GB RDIMMs. Systems that require unbuffered UDIMMs, non-ECC memory, lower voltages, different pin counts or speeds other than DDR5 4800 cannot use these modules. Buyers needing smaller increments or consumer desktop compatibility should look elsewhere.

Sixteen-module 1 TB kit at DDR5 4800

The decisive specification is the sixteen-module 1 TB configuration delivering 64 GB per registered ECC RDIMM at DDR5 4800 CL40 1.1 V. This exact kit matches the XE9640 slot count and density requirement; any deviation in module count, capacity per module, rank structure or voltage makes the kit incompatible with the target server.

Questions about this item

Will these 288-pin DDR5 RDIMMs physically fit the memory slots in a Dell PowerEdge XE9640?

Yes, the kit uses the standard 288-pin DDR5 RDIMM form factor that matches the XE9640 memory sockets.

What is the correct sequence for populating the 16 modules during installation, and which step is most often missed?

Follow the Dell XE9640 service manual channel population order exactly; the step most often missed is seating each module until both retention clips click.

If a module fails years later, what replacement does the kit require?

Replace the failed stick with another 64 GB DDR5 4800 CL40 2Rx4 1.10 V ECC RDIMM to keep the 1 TB kit matched.
