16 GB DDR4 UDIMM for Dell PowerEdge R240

This 16 GB DDR4 module is built for the Dell PowerEdge R240 server. It targets administrators who need a single 16 GB stick to expand memory capacity in that specific platform.

Unbuffered non-ECC design with 288-pin layout

The stick uses a standard 288-pin UDIMM form factor without a heat spreader. Unbuffered non-ECC operation means it installs directly into the server's DIMM slots and runs at 1.2 V with CL19 timing.

Verify the R240 memory population rules before

Check the server's qualified vendor list and maximum supported capacity per slot. Confirm the system accepts 2Rx8 organisation at 2666 MT/s and that no larger registered or ECC modules are required for your configuration.
