Purpose-built laptop upgrade

This 16 GB kit contains two 8 GB DDR3L SODIMM modules rated at 1600 MHz and 1.35 V. It is built for owners of Acer Aspire ES1-571 models 30XX, 31XM, 33BQ and C4E2 who need the maximum supported memory. The unbuffered, non-ECC design matches the factory specification for these notebooks.

Sustained workload behaviour

CL11 timings of 11-11-11 keep latency low during long compile jobs, multi-tab browsing or virtual-machine sessions. The low-voltage DDR3L chips run cooler than standard DDR3, helping the laptop’s thermal solution maintain clock speeds without throttling. No heat spreader is fitted, so airflow in the memory compartment remains unrestricted.

Compatibility checklist

Verify that your Aspire ES1-571 currently uses two 204-pin SODIMM slots and that the BIOS recognises 8 GB modules per slot. Remove any existing sticks before installing the matched pair to ensure dual-channel operation. The kit is not suitable for systems requiring ECC, registered memory or a different DDR generation.

Questions about this item

How much heat or power draw should I expect from the 1.35 V DDR3L modules running continuously in an Acer Aspire ES1-571?

At 1.35 V the DDR3L sticks consume less power and generate less heat than standard 1.5 V DDR3, so all-day operation stays cool and quiet inside the laptop chassis.

Does my ES1-571 need both SODIMM slots free to install this 2 x 8 GB kit?

The kit fills both 204-pin slots, so any existing modules must be removed; the system supports a maximum of 16 GB across its two sockets.

Will the CL11 timing work with the memory controller in my ES1-571 without manual BIOS changes?

The modules run at standard JEDEC CL11 11-11-11 timings at 1600 MHz, which the notebook configures automatically on boot.
