Targeted Dell Upgrade

This 4 GB DDR4 SODIMM module is built for Dell OptiPlex 3050 All-in-One, OptiPlex 7040 Micro and OptiPlex 7440 systems. It suits users who need a straightforward capacity increase on those specific platforms without changing memory generation.

Simple Slot Addition

The stick uses the standard 260-pin SO-DIMM form factor and runs at 1.2 V unbuffered, so it drops into an empty slot on the listed OptiPlex models. Adding it leaves any second slot free for a future module up to the platform’s 16 GB limit. Buyers whose systems already populate both slots or who require ECC registered memory cannot use this kit.

Cool Silent Operation

With no heat spreader and a low 1.2 V operating voltage, the module adds minimal thermal load inside compact All-in-One or Micro chassis. Passive cooling keeps noise at zero while the CL17 2400 MHz timing delivers stable throughput for everyday workloads.

Questions about this item

Will the 2400 MHz speed hold steady under continuous load or will it throttle?

The module runs at 2400 MHz with CL17 timings at 1.2 V; DDR4 SO-DIMMs have no active cooling so speed is limited by the platform memory controller, not the stick itself.

How much heat and noise does this 1.2 V stick add to a Dell OptiPlex 7040 Micro running 24/7?

At 1.2 V with no heat spreader the module produces minimal heat and zero noise; the Micro chassis fan handles all cooling.

My OptiPlex 3050 All-in-One has two SODIMM slots — do I need matching pairs or can I add this single 4 GB stick?

The system supports up to 16 GB across two slots; this unbuffered 2Rx8 module works alone or paired with another DDR4 2400 SO-DIMM.
