Dell PowerEdge C6420 compatible memory

This 16GB DDR4 registered DIMM is built for the Dell PowerEdge C6420 server. It targets administrators who need to expand capacity in that specific platform without mixing unbuffered modules. The ECC design protects data integrity in multi-socket workloads. Buyers needing non-ECC memory for desktop boards should look elsewhere.

Straightforward server DIMM installation

The module seats in a standard 288-pin DDR4 RDIMM slot and operates at 1.20V. No heat spreader is fitted, so airflow in the chassis does the cooling. The most common issue is populating slots in the wrong order for the C6420 memory architecture; always follow the system service manual for channel population rules. Mixing ranks or speeds across channels can prevent the server from posting.

2933MHz CL21 registered ECC spec

The decisive figure is the DDR4 2933 speed with CL21 latency in a 2Rx8 registered ECC configuration. This exact combination matches the C6420 qualified-vendor list. If your chassis requires a different speed grade, rank layout, or unbuffered DIMMs, this module will not be compatible.

Questions about this item

How can I confirm the module is running at 2933 MT/s with CL21 after installing it in my Dell PowerEdge C6420?

Enter the system BIOS or iDRAC interface after boot; the memory information screen will show the configured speed as 2933 MT/s and the CAS latency as CL21 for each installed DIMM.

What does the package contain and is anything else required for installation?

The box includes one 16 GB 288-pin DDR4 ECC registered DIMM (part number MR23400-628K1); no extra cables, brackets or software are needed — just an available RDIMM slot in the C6420.

Which capacity or rank option should I choose for the C6420 if I want to maximise memory per slot?

This 16 GB 2Rx8 module is the highest-capacity single DIMM in this series; selecting it gives you the maximum density per slot while maintaining full ECC registered operation.
