Compatible Dell Inspiron 15 models

This 4GB DDR3L SODIMM module is built for Dell Inspiron 15 laptops including the 3541, 5555, 5559, 7537 and 7558. It targets owners of those systems who need a straightforward memory increase for everyday multitasking and general productivity.

Upgrading from lower capacity or slower DDR3L

The module replaces an existing stick or fills an empty slot to raise total system memory. The jump is worthwhile when the current configuration limits the number of open applications or causes frequent disk swapping during typical workloads.

Fits 204-pin DDR3L slots at 1.35V

Installation uses the standard SODIMM socket inside the supported Inspiron chassis. The 1.35V DDR3L specification ensures compatibility with the platform's memory controller without requiring voltage changes. Buyers needing ECC, registered buffers or speeds beyond 1600 MT/s should look elsewhere.

Questions about this item

Will this 204-pin DDR3L SODIMM fit the memory slot in my Dell Inspiron 15 5559?

Yes, the module uses the standard 204-pin DDR3L SODIMM form factor required by the Inspiron 15 3541, 5555, 5559, 7537 and 7558.

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

Align the notch with the key in the slot, press firmly until the side clips click into place, then verify the new 4 GB capacity appears in BIOS or the OS.

Does this non-ECC 1.35 V stick need any firmware updates or periodic replacement?

No firmware is required; the JEDEC-standard DDR3L module is designed for the life of the laptop and only needs replacement if a fault develops.
