Targeted upgrade for Acer Aspire laptops

This 4 GB DDR3L SODIMM is built for the Acer Aspire V3-731-4439, V3-551-8442 and E1-431-4404. It installs in a 204-pin slot and runs at 1.35 V to match the factory memory specification. The module is unbuffered and non-ECC, making it a direct replacement for the original equipment.

Capacity and headroom

The stick provides 4 GB in a single rank 1Rx8 configuration. The compatible platforms support a maximum of 8 GB across two sockets, so this module fills half the available capacity. Adding a second identical stick would reach the platform limit, while a single module leaves room for one more upgrade.

DDR3L 1600 interface limits

The module operates at DDR3L 1600 (PC3L 12800) with CL11 11-11-11 timing. It is also rated to run at DDR3 1866 (PC3 14900) with 10-10-10-30 timing at 1.5 V. The DDR3L standard tops out at these speeds, so no higher frequency or lower latency is available within this generation.

Questions about this item

Will this 1.35 V DDR3L SODIMM run stably in an Acer Aspire V3-731-4439 that originally used 1.5 V DDR3 modules?

Yes — DDR3L is backward compatible with 1.5 V slots; the module will operate at 1.35 V and 1600 MHz without any configuration changes.

How can I confirm the stick is recognised at 1600 MHz CL11 after installing it in my Acer Aspire E1-431-4404?

Open Task Manager → Performance → Memory or run CPU-Z; both will show 1600 MHz speed, CL11 timings and 4 GB capacity.

The listing says “1 Memory RAM Stick” — does the package include any installation tools or thermal pads?

The box contains only the 4 GB SODIMM module; no tools, screws or thermal pads are included.
