OWC 2GB DDR3 SODIMM for Inspiron 3521

This module is a 2GB DDR3 1600 CL11 1.5V SODIMM built to JEDEC standards for the Dell Inspiron 15 3521. It installs in a 204-pin slot as a single 1Rx8 unbuffered stick. The upgrade targets owners of that specific laptop seeking a direct replacement or capacity increase.

Suits owners adding a single stick to a free slot

Buyers needing a matched pair or a larger single module should look elsewhere. The part is validated only for the named model and carries no heat spreader. Systems requiring ECC or registered memory cannot use this non-ECC unbuffered design.

Only laptops accepting 204-pin DDR3 SO-DIMMs at 1.5V can install this module. The Inspiron 15 3521 is the qualified platform; other DDR3 systems may work but are not verified by the manufacturer.
