Dell Inspiron 17 3781 memory upgrade

This 16GB DDR4 SODIMM is built specifically for the Dell Inspiron 17 3781 laptop. It delivers 2133MHz speed with CL15 latency at 1.2V. The unbuffered non-ECC module uses a 260-pin layout and 2Rx8 rank. It targets owners who need more capacity for multitasking and larger workloads.

Replaces lower-capacity factory modules

The upgrade swaps out the original 4GB or 8GB sticks that shipped with the 3781. The jump is worth it when the system slows down with multiple browser tabs, office apps or light creative work open. Buyers who want error-correcting memory or registered DIMMs cannot use this module.

Simple DIY installation

The SODIMM slots are accessible under a bottom panel on the Inspiron 17 3781. Align the notch, press firmly until the clips click, then replace the cover. What usually goes wrong is seating the stick at an angle or forgetting to remove AC power and the battery first.
