System-Specific DDR4 SODIMM for Dell Inspiron 17

This 4GB OWC module is built to JEDEC DDR4 2133MHz PC4-17000 standards with CL15 latency and 1.2V operation. It targets owners of the Dell Inspiron 17 3781 who need a direct-fit memory upgrade without compatibility guesswork.

Upgrade from 4GB or 8GB factory configurations

The jump is worthwhile when the Inspiron 17 3781 ships with a single 4GB stick or two 4GB sticks leaving no free slots. Adding this module raises total capacity for smoother multitasking and larger file handling in everyday workloads.

260-pin unbuffered non-ECC SODIMM fit

The stick plugs straight into the laptop DDR4 SO-DIMM slot and requires no heat spreader or extra clearance. It frees the builder from hunting generic modules that may not meet the 3781’s exact timing or voltage needs.

Questions about this item

Will the 260-pin SODIMM fit the memory slot on a Dell Inspiron 17 3781?

Yes, the module is a 260-pin DDR4 SODIMM built specifically for the Inspiron 17 3781 and matches the laptop's slot and voltage requirements.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, insert at a slight angle, then press down firmly until both side clips click; the step often missed is verifying both clips have fully locked.

Does the 1Rx8 rank configuration affect future upgrades or replacement options?

The single-rank 1Rx8 layout leaves the second slot free for another module, so you can add a matching stick later without rank conflicts.
