Computer Memory Solutions CM5126410600SODRH 4GB DDR3 1333MHz SO-DIMM memory upgrade

Target laptop upgrade

This 4GB DDR3 SO-DIMM module is built for Asus and Asmobile A53 series notebooks including the A53E, A53Sv, A53Ta and A53U. It adds a single 4GB stick running at 1333MHz with CL7 timing for owners who need more memory in those specific models. Buyers whose laptops use a different DDR generation or form factor cannot use this module.

Check your current setup

Verify that your A53 series laptop has a free 204-pin DDR3 SO-DIMM slot and that the installed memory also runs at 1.5V. The system supports a maximum of 8GB across two sockets with 4GB per socket, so confirm the existing stick capacity before ordering. A 64-bit operating system is required to address the full 4GB; otherwise the recognised amount may drop to 3.5GB or less.

Thermals and power in use

The module operates at the standard DDR3 voltage of 1.5V and has no heat spreader, relying on the laptop’s internal airflow for cooling. As an unbuffered, non-ECC stick it draws minimal power and produces no audible noise during normal operation. Typical CL7 timing at 1333MHz keeps latency low without increasing thermal output.
