Computer Memory Solutions CM1024642133DIMM 8GB DDR4 2133MHz memory upgrade Dell OptiPlex 7040 SFF

System-specific 8 GB DDR4 module

This 8 GB DDR4 DIMM is built for the Dell OptiPlex 7040 SFF and carries the Computer Memory Solutions CM1024642133DIMM part number. It is a single 288-pin unbuffered non-ECC stick rated at 2133 MHz with CL15 timing. The module runs at 1.2 V and uses a 2Rx8 rank configuration. It is intended for owners of that specific OptiPlex who need to add or replace memory.

Capacity headroom up to 64 GB

The OptiPlex 7040 SFF supports a maximum of 64 GB across four DIMM slots, so this 8 GB stick leaves ample room for further upgrades. One module installs in a single slot and the system will run at the rated 2133 MHz speed. If all four slots are filled the total capacity reaches the platform limit, while a single stick covers modest multitasking needs. Buyers who want more than 64 GB total capacity cannot use this platform.

288-pin DDR4 2133 MHz non-ECC specification

The decisive specification is the 288-pin DDR4 2133 MHz non-ECC unbuffered DIMM form factor with CL15 15-15-15 timing at 1.2 V. Only systems that accept this exact DDR4 DIMM type will recognise the module. Builders needing ECC, registered, SODIMM or a different DDR generation must choose a different part.
