Dell PowerEdge XE7100/XE7420/XE7440 Kit

This NEMIX RAM kit delivers 128GB of DDR4 3200 ECC registered memory in two 64GB modules. It is built for Dell EMC PowerEdge XE7100, XE7420 and XE7440 rack servers that require registered DIMMs with error correction. The modules run at 1.2V with a CAS latency of CL22 and use a 2Rx4 rank configuration.

IT teams running virtualised workloads

The registered ECC design suits administrators who need data integrity and stability for virtualisation, databases or high-performance computing on the listed PowerEdge platforms. Builders assembling custom white-box servers or workstations that accept only unbuffered UDIMMs should look at something else, as registered modules will not function in those systems.

128GB dual-module capacity

Two 64GB RDIMMs provide a dense starting point for memory-hungry applications and leave additional DIMM slots open for future expansion on supported motherboards. The kit reaches its limit when the server's maximum supported memory per channel or total system capacity is reached, which varies by specific CPU configuration and BIOS revision.

Questions about this item

Does this kit require a Dell PowerEdge server with DDR4 RDIMM slots to function?

Yes, the 288-pin DDR4 RDIMM modules are built for Dell PowerEdge XE7100, XE7420 and XE7440 rack servers that accept registered ECC memory.

Can I mix these 64 GB 2Rx4 modules with existing 32 GB RDIMMs in the same server?

The kit runs at 3200 MT/s CL22 1.20 V; the server will clock all installed RDIMMs to the lowest common speed and timing.

How do I confirm the full 128 GB is recognised and ECC is active after installation?

Check the system BIOS or iDRAC inventory — it should show 128 GB total across two 64 GB 2Rx4 modules with ECC status enabled.
