Target Netbook Upgrade

This 2GB DDR2 SO-DIMM module is built for Acer Aspire One D255, 531h, 532h, 751h, D250, D255E, D260 and P531h netbooks that accept a single 200-pin slot. It delivers a straight-forward capacity increase for owners of those specific models running an operating system other than Windows 7 Starter.

Physical Fit And Signal

The stick uses a standard 200-pin SO-DIMM edge connector and runs at 1.8V without a heat spreader, so it slides into the single expansion socket found in the listed netbooks. Unbuffered, non-ECC operation with 5-5-5 timing at 667MHz matches the platform’s native memory controller requirements.

Check Slot And OS Limit

Verify that your netbook is one of the exact model numbers shown and that it has the single SO-DIMM socket free. Confirm the installed operating system is not Windows 7 Starter, which caps usable memory at 1GB on these platforms.
