Dell PowerEdge R640 64 GB DDR4 RDIMM

This 64 GB DDR4 registered DIMM runs at 2933 MT/s with CL21 latency and 1.2 V operation. It uses a 2Rx4 organisation and 288-pin form factor with ECC for error correction. The module is built for the Dell PowerEdge R640 rack server and carries part number MR23400-924K1.

Suited for IT teams expanding R640 memory capacity

Administrators who need to populate empty slots or replace failed modules in a validated Dell configuration will find this part matches the qualified-vendor list. Buyers whose systems require unbuffered UDIMMs, lower densities, or a different speed grade should look at something else.

2Rx4 registered ECC at 2933 MT/s

The single decisive attribute is the 2Rx4 registered ECC design running at DDR4 2933 (PC4-23400). Only platforms that specifically support this rank structure and data rate will accept the module; verify the server's memory population rules before ordering.
