4GB DDR3L SODIMM for Acer Aspire

This 4 GB DDR3L SODIMM module runs at 1600 MHz with CL11 timing and 1.35 V operation. It is built as a 204-pin unbuffered, non-ECC stick using major-brand components. Computer Memory Solutions validates compatibility with the listed Acer Aspire ES1-572 models.

Suitable for single-slot upgrades

The module fits notebooks that accept one 204-pin DDR3L SODIMM and supports the specified Acer configurations. Buyers who need more than 4 GB per slot or require ECC error correction should look elsewhere. Systems limited to 1.5 V DDR3 without DDR3L support cannot use this memory.

1.35 V DDR3L voltage

This stick operates at 1.35 V, the defining electrical characteristic of the DDR3L standard. A notebook that only supplies 1.5 V to its memory slots will not run this module correctly, making voltage the decisive compatibility check.

Questions about this item

What laptop models does this 204-Pin DDR3L 1600 SODIMM support?

This module is validated for Acer Aspire ES1-572-31KW, ES1-572-31XL, ES1-572-356C and ES1-572-357C notebooks.

Can I pair this 1.35 V DDR3L stick with existing 1.5 V DDR3 memory?

Yes, DDR3L runs at 1.35 V and is backward-compatible with 1.5 V DDR3 slots; the system will operate both at the higher voltage.

How do I confirm the CL11 1600 MHz timing is active after installation?

Open Task Manager or CPU-Z and verify the memory shows 1600 MHz speed with 11-11-11 latency timings.
