Dell PowerEdge Server Memory Upgrade

This OWC 32GB DDR4 module is built for Dell PowerEdge R550, R640, R740, R740XD and R740XD2 servers. It targets administrators who need to expand ECC registered memory capacity in these specific platforms. The part is not suitable for standard desktop computers or workstations that require unbuffered memory.

Registered ECC RDIMM Architecture

The single specification that determines fit is the 288-pin DDR4 ECC Registered RDIMM form factor with a 2Rx4 rank configuration. This module will not function in systems that only accept unbuffered UDIMMs or non-ECC memory. Mixing it with unbuffered modules is not supported.

32GB Capacity at 2933MHz

A 32GB stick comfortably handles virtualisation workloads, database caching and multi-tenant applications on the listed PowerEdge models. The module operates at 2933MHz CL21 and is backward compatible with 2133MHz, 2400MHz and 2666MHz bus speeds. It runs out of headroom when total system memory demand exceeds the server's maximum supported capacity or available DIMM slots.

Questions about this item

What does the 2933MHz speed mean for my Dell PowerEdge R740?

The module runs at 2933MHz when the server's memory controller supports that rate; if the controller is limited to a lower speed the DIMM will automatically downclock to match.

How does the PC4-23400 rating affect real-world bandwidth?

PC4-23400 is the JEDEC designation for DDR4-2933; the peak transfer rate per module is defined by that standard and will be limited by the number of populated memory channels in the R550, R640, R740, R740XD or R740XD2.

Will the 288-pin registered ECC DIMM fit in a PowerEdge R640?

Yes, the 288-pin RDIMM form factor with ECC and registered buffering is the correct physical and electrical match for the R640 and the other listed PowerEdge models.
