System-Specific 4GB DDR3L SODIMM

This 4GB DDR3L 1866MHz SODIMM module is built for Dell Inspiron 15 3000 Series notebooks requiring a 204-pin unbuffered upgrade. It suits owners of those systems who need a direct replacement or a single-slot capacity increase without configuration changes.

Single-slot 4GB capacity headroom

The stick provides 4GB in a 1Rx8 layout at 1.35V with CL13 timing, filling one of the two available sockets. The platform supports up to 16GB total, so a second identical module can be added later to reach the maximum.

Unbuffered non-ECC build for laptop sockets

The module uses major-brand chips on a standard 204-pin PCB without a heat spreader, keeping the profile low for tight chassis. Its non-ECC unbuffered design matches the laptop's memory controller, and the single-piece kit simplifies installation in either slot.

Questions about this item

Will the 1.35 V DDR3L SODIMM run stably in an older laptop that only supports 1.5 V DDR3?

The module is DDR3L rated at 1.35 V and will operate at that voltage when the system supports DDR3L; if the platform only accepts 1.5 V DDR3 the memory may not be recognised or could run at reduced speed.

How can I verify the CL13 13-13-13 timings are active after installing the 4 GB stick?

Open Task Manager or a tool such as CPU-Z and check the memory tab — it should show 1866 MHz and CAS latency 13 with timings 13-13-13.

Does the single 204-pin stick come alone or are extra brackets or screws included?

The package contains only one 4 GB DDR3L SODIMM stick; no brackets, screws or additional accessories are supplied.
