Dell PowerEdge R840 DDR4 RDIMM

This NEMIX RAM module provides 16 GB of DDR4 2933 registered ECC memory for the Dell PowerEdge R840 rack server. It operates at 1.2 V with a CAS latency of CL21 and uses a 2Rx8 organisation on a 288-pin RDIMM form factor. The part is built with major OEM chips from Samsung, Micron or Hynix and carries the supplier part number MR23400-628K1.

IT teams maintaining R840 fleets

Administrators expanding memory in a Dell PowerEdge R840 will find this module validated for that platform. Builders working on non-Dell servers, desktop workstations or consumer motherboards should look elsewhere because the registered ECC design requires a compatible server chipset and memory controller.

Registered ECC DDR4 2933 CL21

The single specification that determines fit is the registered ECC DDR4 2933 CL21 2Rx8 288-pin RDIMM profile at 1.2 V. Only systems that explicitly support this exact combination of speed, latency, rank structure and registered signalling will accept the module.

Domande su questo articolo

Does this RDIMM require a Dell PowerEdge R840 server to function?

This module is built for the Dell PowerEdge R840 and operates as registered ECC DDR4; the server must accept 288-pin DDR4 RDIMMs at 2933 MT/s with 1.20 V.

Can I mix this 16 GB 2Rx8 CL21 stick with existing DDR4 RDIMMs running at a lower speed?

The R840 will down-clock all modules to the slowest installed speed and use the loosest timing, so mixing works but the faster 2933 MT/s rating on this stick will not be used.

How do I verify the module is running at 2933 MT/s with ECC active after installation?

Enter the system BIOS or iDRAC and confirm the memory speed shows 2933 MT/s, the rank reads 2Rx8, and ECC status reports enabled.
