Dell PowerEdge R940 memory upgrade

This 32 GB DDR4 module is built for the Dell PowerEdge R940 server platform. It delivers registered ECC operation at 2933 MHz for workloads that demand data integrity and high capacity. System administrators expanding memory in a compatible R940 chassis can install this single DIMM to increase total system memory.

Registered ECC DDR4 platform limits

The RDIMM form factor requires a motherboard that supports registered, error-correcting memory and a 288-pin DDR4 slot. Mixing registered and unbuffered modules is not supported, and the platform must accept 2Rx4 organisation at 1.2 V. Maximum capacity per slot and total system capacity are defined by the server specifications.

CL21 latency at 2933 MHz

CAS latency of 21 cycles at the rated 2933 MHz speed determines the timing profile for this module. Buyers needing lower latency or higher frequency should verify the server memory configuration rules before purchasing. Systems locked to slower bus speeds will downclock this DIMM automatically.

Questions about this item

Is the 32GB single module the right choice for expanding a Dell PowerEdge R940?

Yes, this 32GB 2Rx4 RDIMM is built for the PowerEdge R940 and installs as a single stick.

What does the 2933MHz rating deliver inside a running server?

The module runs at DDR4 2933 with CL21 latency, providing the rated throughput when the platform enables that speed.

How does the 288-pin DDR4 RDIMM interface limit performance?

The registered 288-pin DDR4 slot caps bandwidth to PC4-23400 and requires ECC registered memory, which this module supplies.
