Dell PowerEdge R240 server memory
This 16 GB DDR4 2666 ECC registered DIMM is built for the Dell PowerEdge R240 rack server. It targets administrators who need to add a single 288-pin module to expand capacity on that platform. The registered design and error-correcting code suit always-on workloads where data integrity matters.
Installation and common issues
The module fits a standard 288-pin DDR4 slot and installs in minutes; Dell’s service manual shows the exact population order for the R240. Problems usually arise when mixing registered ECC with unbuffered non-ECC DIMMs or when the firmware expects a different rank layout, so follow the vendor’s configuration guide.
Capacity, speed and rank constraint
The single rank 2Rx8 organisation at 2666 MT/s CL19 and 1.2 V determines whether the memory controller accepts the module. If your R240 configuration requires a different rank count, voltage or latency the system will not post.

Questions about this item
How can I verify the 16GB DDR4 2666 ECC RDIMM is operating correctly after installing it in a Dell PowerEdge R240?
The server POST will display the new 16GB capacity and 2666 MT/s speed; ECC status appears as "Enabled" in the BIOS memory configuration, and iDRAC or OpenManage will report zero correctable errors during initial stress testing.
What is included in the package and what additional components are required for installation in the R240?
The box contains one 16GB 2Rx8 CL19 288-pin DDR4 RDIMM; no extra cables, brackets or tools are needed — the module seats directly into an available DDR4 DIMM slot on the R240 motherboard.
Which capacity and rank configuration should I select if I need a single module to expand a Dell PowerEdge R240?
Choose the 16GB 2Rx8 variant (part number MR21300-628K1); it matches the R240's supported DDR4 2666 registered ECC specification and installs as a single 16GB DIMM.
