4GB DDR3 1333MHz SO-DIMM for Acer Aspire

This 4GB DDR3 1333MHz SO-DIMM module is built for Acer Aspire E1-531 and E1-571 notebooks. It runs at PC3-10600 speed with CL7 latency and 1.5V operation. The unbuffered, non-ECC design suits standard laptop memory slots. It targets users restoring or upgrading these specific Acer models.

Sustained load behaviour

The module uses major-brand chips rated for DDR3-12800 1600MHz but operates at the system 1333MHz setting. CL7 7-7-7 timings and 1.5V voltage deliver stable throughput during extended sessions. The 2Rx8 rank organisation helps maintain bandwidth without buffering overhead. No heat spreader is fitted, so chassis airflow manages thermals.

Compatibility checks

Verify your laptop is an Acer Aspire E1-531-4444, E1-531-4694 or E1-571-6442 before ordering. The system maximum is 8GB across two sockets with 4GB standard. This single 4GB stick fills one slot; a second identical module is required to reach the 8GB limit. DDR3 generation is mandatory — other generations will not fit the 204-pin socket.

Questions about this item

Does the 1.5 V DDR3-1333 SO-DIMM run hot or noisy during all-day use?

No — memory modules have no moving parts and draw little power at 1.5 V, so they stay silent and only warm to the touch under continuous load.

My Acer Aspire E1-531-4444 currently has 4 GB in one slot; do I need any tools or extra parts to add this stick?

Only a small Phillips screwdriver to open the bottom memory door; the laptop already has a second free 204-pin SO-DIMM socket and no other components are required.

Will this CL7 1333 MHz module work reliably alongside the original 1333 MHz stick already installed?

Yes — both run at DDR3-1333 (PC3-10600) and the system will simply operate them in dual-channel mode at the shared speed and timing.
