System-specific DDR3 SO-DIMM for Acer Aspire One

This 2 GB DDR3 1066 module is built to the exact electrical and mechanical specification of the Acer Aspire One D257-13404. It arrives as a single 204-pin SO-DIMM rated at 1.5 V with CL7 7-7-7 timings, allowing a straightforward replacement of the factory-installed stick. No configuration is required beyond inserting the module into the sole memory socket.

Ideal for owners restoring the netbook to its 2 GB

The upgrade suits anyone whose D257-13404 currently runs a single 1 GB module and needs the full 2 GB ceiling for smoother multitasking. Because the platform provides only one socket, the existing 1 GB stick must be removed; this kit does not support adding a second module alongside the original. Buyers needing ECC, registered buffering, or capacities beyond 2 GB should look at other platforms.

204-pin DDR3 1066 SO-DIMM at 1.5 V CL7

The decisive specification is the 204-pin DDR3 1066 (PC3 8500) interface with 1.5 V unbuffered operation and 1Rx8 organisation. Only modules matching this exact pin count, voltage, speed and timing will be recognised by the netbook’s memory controller. Verify the socket is free and the original 1 GB stick is removed before installation.
