Dell PowerEdge R940 ECC RDIMM

This 16 GB DDR4 module is built for the Dell PowerEdge R940 server. It carries ECC and registered operation to protect data integrity in enterprise workloads. The single-stick design lets administrators add capacity one slot at a time.

Tool-free DIMM installation

The 288-pin RDIMM seats in the standard DDR4 server slots without extra brackets or cables. Alignment keys prevent backwards insertion, and the low-profile form clears most CPU coolers. Common issues arise when mixing ranks or speeds across channels, so match the existing CL21 2933 MT/s specification.

Registered ECC at 2933 MT/s

The registered buffer and on-die ECC are the decisive spec for R940 compatibility; unbuffered or non-ECC modules will not post. This stick delivers PC4-23400 bandwidth at 1.2 V with a 2Rx8 organisation. Buyers needing non-ECC or higher-frequency memory should look elsewhere.

Questions sur cet article

How do I confirm the module is running at DDR4 2933 PC4-23400 with ECC active after installing it in the PowerEdge R940?

Enter the system BIOS or iDRAC interface after boot; the memory configuration screen will show each DIMM running at 2933 MT/s, PC4-23400 data rate, CL21 latency, 1.2 V, and ECC status as enabled for the registered 2Rx8 module.

What comes in the package and what must be sourced separately for the Dell PowerEdge R940 upgrade?

The box contains one 16 GB 288-pin DDR4 RDIMM (part MR23400-628K1); no heat spreader, tools, cables or additional DIMMs are included, so any extra modules or server rail kits must be purchased separately.

Which capacity and rank configuration should I choose for the R940 when the options include this 16 GB 2Rx8 registered ECC RDIMM?

Select this 16 GB 2Rx8 CL21 1.2 V module when you need a single registered ECC DIMM to populate an empty slot or match existing 2Rx8 sticks; the 288-pin DDR4 2933 specification ensures compatibility with the R940 memory architecture.
