Dell PowerEdge R740xd memory upgrade

This NEMIX RAM module provides 64GB of DDR4 2933MHz ECC registered memory for the Dell PowerEdge R740xd rack server. The single 2Rx4 DIMM operates at 1.2V with CL21 latency and uses major OEM chips from Samsung, Micron or Hynix.

Check DDR4 RDIMM slot availability

Verify that your R740xd has a free 288-pin DDR4 RDIMM slot and consult the server manual for supported memory configurations and maximum capacity per processor. The module requires registered ECC support and must match existing memory speed and rank requirements for stable operation.

Suits IT teams expanding R740xd capacity

This upgrade fits administrators adding memory to a compatible Dell PowerEdge R740xd for virtualization or database workloads. Builders needing unbuffered UDIMMs, non-ECC modules, DDR5 memory or speeds above 2933MHz should look at other products.
