Targeted 4 GB DDR3L upgrade for select Acer Aspire

This SODIMM module delivers 4 GB of DDR3L memory at 1600 MHz with CL11 timing and 1.35 V operation. It is built specifically for Acer Aspire E1-531-4461, E1-532P-4819 and E1-570-6803 notebooks. The unbuffered, non-ECC design uses a 1Rx8 rank configuration on major-brand chips.

Straightforward 204-pin installation

The stick slots into a standard 204-pin SO-DIMM socket and requires no tools beyond a screwdriver to open the memory hatch. The only frequent issue is inserting the module at the wrong angle; it must click firmly into both retention clips before the hatch is closed.

Verify your exact model

Confirm the laptop is one of the three listed Aspire part numbers, as other E1-series units may use different memory specifications. The system supports a maximum of 8 GB across two sockets, so check whether the second slot is already occupied or if the existing 4 GB module will be replaced.

Questions about this item

How can I confirm the 4GB DDR3L 1600 SODIMM is running at CL11 1.35V after installation?

Open Task Manager or your BIOS and verify the module reports 4GB capacity, 1600MHz speed and 1.35V voltage.

What comes in the box and do I need any extra parts to fit it in my Acer Aspire E1-531-4461?

The package contains one 204-pin SODIMM stick; no additional parts are required for the listed Acer models.

Should I choose the 1.35V DDR3L version or the 1.5V DDR3 version for the E1-570-6803?

Select the 1.35V DDR3L module; it is backward compatible with 1.5V DDR3 slots and matches the specified voltage.
