2GB DDR3-1066 SODIMM for Acer Aspire One D257

This 2GB DDR3 SO-DIMM runs at 1066 MHz with CL7 timing and 1.5V operation. It is built for the Acer Aspire One D257 with Atom N570 or N550 processors. The unbuffered, non-ECC module uses a single 1Rx8 rank and fits the 204-pin slot. Computer Memory Solutions guarantees compatibility with the listed models.

Replaces the factory 1GB module in a single socket

The Aspire One D257 ships with 1GB in its only memory slot, so upgrading requires removing that module and inserting this 2GB stick. The jump is worth it when the netbook feels sluggish with multiple browser tabs or office applications open. No other memory slots exist, so this module defines the final capacity.

Handles everyday browsing

At the system maximum of 2GB, the module covers typical light productivity and web use on the Atom platform. It runs out when heavier multitasking, modern web apps, or background updates push memory pressure beyond the 2GB ceiling. The single-socket design means no further expansion is possible.

Questions sur cet article

Will this 204-pin DDR3 SODIMM fit the memory slot in my Acer Aspire One D257?

Yes, the 204-pin DDR3 SODIMM form factor matches the single expansion socket in the Acer Aspire One D257 Atom N570 and N550 models.

Do I just snap the module in, or is there a specific way to seat the 204-pin SODIMM?

Insert the module at an angle until the gold contacts are fully hidden, then press down firmly until both side clips click; the common mistake is stopping before the clips engage.

Will I need to replace this 2GB module again if I want more memory later?

The system maximum is 2GB with one socket, so this module already reaches the limit; any future increase would require a different platform.
