System-specific 4GB DDR4 SODIMM for Dell OptiPlex

This 260-pin DDR4 module delivers 4GB at 2133MHz with CL15 latency and 1.2V operation. It is validated for the Dell OptiPlex 7040 Micro and meets JEDEC PC4-17000 specifications. The unbuffered, non-ECC design suits the platform's memory controller directly.

Sustained multitasking stability

Under continuous workloads the module maintains its rated 2133MHz speed and CL15 timings without throttling, because it operates at the standard 1.2V JEDEC voltage. The 1Rx8 organisation provides consistent bandwidth for office applications, web browsing and light content creation. Compliance testing ensures error-free operation during extended sessions.

Verify single-slot capacity limit

Confirm the OptiPlex 7040 Micro accepts a 4GB SODIMM in its available slot and that the system BIOS recognises the full capacity. Ensure the existing memory is also DDR4 2133MHz non-ECC unbuffered; mixing generations or ECC types will prevent boot. The 260-pin form factor fits only DDR4 SO-DIMM sockets.

Questions about this item

How much power does the 1.2V DDR4 module draw when the OptiPlex 7040 Micro runs continuously?

The module operates at the standard DDR4 voltage of 1.2V, keeping power draw low during all-day use in the Micro chassis.

Does the 260-pin SODIMM fit straight into the OptiPlex 7040 Micro without an adapter or extra parts?

Yes, the 260-pin DDR4 SODIMM is the native form factor for the OptiPlex 7040 Micro, so it installs directly into the memory slot.

Will this CL15 2133MHz stick work alongside the original memory already in my OptiPlex 7040 Micro?

It is built to JEDEC DDR4-2133 CL15 specs, so it will run at the same speed and timings as the factory-installed modules.
