Target systems

This 4GB DDR3L SO-DIMM is built for the Acer Aspire E1-571-6856, E1-572P-6403 and E1-572P-6468 notebooks. It plugs into a 204-pin slot and runs at 1600 MHz with CL11 timing. The module operates at 1.35V and uses a 1Rx8 unbuffered layout. It is intended for owners of those specific models who need a direct memory replacement or upgrade.

Upgrade path

The laptop platform supports a maximum of 8GB across two sockets. Installing this stick adds 4GB to one slot, leaving the second socket available for a matching module to reach the limit. The jump is worthwhile when the system currently runs on less than 8GB and the workload demands more capacity for multitasking or larger datasets. Buyers who need more than 8GB total cannot be served by this platform.

Sustained operation

The module uses standard major-brand chips without a heat spreader and runs at the low 1.35V DDR3L voltage. This keeps thermal output modest during extended sessions. The CL11 11-11-11 timing remains stable at the rated 1600 MHz speed under continuous load. No throttling behaviour or thermal limits are specified by the supplier.

Questions about this item

Does this 204-pin SO-DIMM fit the two memory sockets in my Acer Aspire E1-571-6856?

Yes, the module is built for the two SO-DIMM slots in that laptop and matches the 4 GB per slot limit for an 8 GB maximum.

What is the correct way to seat this DDR3L stick so the side clips engage?

Align the notch on the module with the key in the slot, push the stick in until the gold contacts are no longer visible, then press down until both metal clips snap into the side notches.

Will this 1.35 V DDR3L module need any firmware update or voltage adjustment later?

No firmware or voltage change is required; the stick runs at the standard 1.35 V and is covered by the manufacturer's limited lifetime warranty.
