Capacity and fit

This kit provides 256GB of DDR4 memory in four 64GB registered ECC modules. It is built for Dell PowerEdge XR4000w, XR4510c and XR4520c rack servers that accept 288-pin RDIMMs.

Who this suits and who should look elsewhere

IT teams expanding those specific Dell platforms will find the speed, voltage and rank configuration match the factory specification. Systems that require unbuffered UDIMMs, a different DDR generation, lower density per module, or a non-Dell memory qualification should look elsewhere.

The specification that decides fit

Each module is a 2Rx4 DDR4 3200 RDIMM running at 1.20V with CL22 latency; the registered ECC design and exact Dell qualification determine whether the kit will post and run without errors.

Questions about this item

Will the 288-pin DDR4 RDIMM modules fit the memory slots in a Dell PowerEdge XR4000w, XR4510c or XR4520c?

Yes, the 288-pin DDR4 RDIMM form factor matches the DIMM slots in the Dell PowerEdge XR4000w, XR4510c and XR4520c servers.

What is the correct order to install the four 64 GB modules so the server recognises the full 256 GB kit?

Populate the DIMM slots following the server's documented channel sequence, typically filling one slot per channel before adding a second rank, and ensure each module clicks fully into its latch.

Do the Samsung, Micron or Hynix chips on these ECC RDIMMs require any periodic maintenance or scheduled replacement?

No, the modules have no moving parts or batteries; they operate continuously without maintenance and are only replaced if a memory error occurs or a capacity upgrade is needed.
