System-specific DDR3 SODIMM

This 2 GB DDR3 SODIMM is built for the Acer Aspire One D257-1818 netbook. It installs in the single 204-pin slot and restores the factory memory configuration. Owners of other Acer models or different laptop brands cannot use this module.

Sustained operation at 1066 MHz

The stick runs at PC3-8500 speed with CL7 7-7-7 timings and 1.5 V unbuffered voltage. Major-brand chips and a 1Rx8 organisation keep data rates steady during long work sessions. No heat spreader is fitted, so airflow in the chassis manages thermals.

Single-slot 2 GB limit

The Aspire One D257-1818 accepts a maximum of 2 GB across one socket, so this module fills the only upgrade path. Builders needing more capacity or a dual-channel pair must choose a different platform.

Questions about this item

How much power does the 1.5V DDR3 SODIMM draw when the Acer Aspire One D257-1818 runs all day?

The module operates at the standard DDR3 voltage of 1.5V and is unbuffered, so it adds only the typical low power draw of a single 2GB stick to the netbook's overall consumption.

What slot must the Acer Aspire One D257-1818 have free for this 204-pin upgrade to fit?

The netbook needs one vacant 204-pin DDR3 SO-DIMM socket; the system supports a maximum of 2GB across its single expansion slot.

Will this PC3-8500 CL7 stick work beside the original memory already in the D257-1818?

The laptop only has one memory socket, so the CMS module replaces whatever stick is installed rather than running alongside it.
