Dell PowerEdge MX740C memory upgrade

This 16 GB DDR4 registered DIMM is built for the Dell PowerEdge MX740C server. It delivers ECC error correction and registered signalling for stable operation in multi-socket enterprise workloads. The module runs at 2933 MT/s with CL21 latency at 1.2 V.

Replaces slower or smaller RDIMMs

Swapping out lower-speed DDR4 modules or lower-capacity sticks lets the memory subsystem keep pace with demanding virtualization and database tasks. The upgrade is worth it when the platform supports 2933 MT/s registered ECC memory and the workload benefits from the extra 16 GB per slot.

Fits 288-pin DDR4 RDIMM slots

The single-rank 2Rx8 module occupies one DIMM slot and requires a server board that accepts registered ECC DDR4 at 1.2 V. No heat spreader is fitted, so airflow in the chassis must handle thermal management. It frees a slot for future expansion while adding 16 GB of registered capacity.

Questions about this item

Does the 288-pin DDR4 RDIMM fit the Dell PowerEdge MX740C memory slots?

Yes, the 288-pin DDR4 RDIMM form factor matches the Dell PowerEdge MX740C memory slots for direct installation.

What is the correct orientation step when installing this CL21 registered module?

Align the notch on the 288-pin edge connector with the slot key, press down evenly until both side latches click, confirming the registered module is fully seated.

When should the 16GB ECC RDIMM be replaced in a Dell PowerEdge MX740C?

Replace the module if the system logs uncorrectable ECC errors, fails memory diagnostics, or no longer recognises the 16GB capacity during POST.
