Compatible Dell Inspiron SODIMM Upgrade

This 4GB DDR3L module runs at 1600MHz with CL11 timings and 1.35V operation. It uses a 204-pin SO-DIMM form factor and unbuffered, non-ECC design. The single-rank 1Rx8 configuration fits the listed Dell Inspiron I15-3521 and I15Rv-954Blk models directly.

Suitable for Single-Slot Capacity Boost

Owners of the compatible Dell Inspiron laptops needing a straightforward memory increase will find this module matches the factory specifications. Systems requiring ECC error correction, registered buffering, higher densities per slot, or a different pin count cannot use this stick.

DDR3L 1600MHz Speed Grade Decides Fit

The memory operates at the DDR3L 1600 (PC3L 12800) speed grade with CL11 latency. If the target laptop demands a different DDR generation, voltage, or timing profile, this module will not be compatible.

Questions about this item

How much power does the 1.35V DDR3L module draw during continuous operation?

The module runs at 1.35V, the standard voltage for DDR3L, which reduces power draw and heat compared to 1.5V DDR3 during all-day use.

Does my Dell Inspiron I15-3521 need a free 204-pin SODIMM slot to install this stick?

Yes, the upgrade requires one vacant 204-pin SODIMM slot; the Inspiron I15-3521 has two sockets, so at least one must be open.

Will this CL11 1600MHz stick work alongside an existing 1333MHz module in the same laptop?

The system will clock both modules to the lowest common speed, so the 1600MHz stick will run at 1333MHz with the older module installed.
