Suits Acer Aspire One AOD255E-2677

The module matches the factory 5300 speed grade and 2Rx8 organisation required by these netbooks. It will not serve systems that need ECC registered memory or capacities above the single-socket 2GB limit. Buyers with other laptop models should verify their exact part number before ordering.

200-pin DDR2 667MHz form factor

The 200-pin SO-DIMM keying and DDR2 electrical interface are the decisive compatibility factors. Only platforms designed for PC2-5300 unbuffered SODIMMs can accept this module.

Questions about this item

Will this 200-pin DDR2 SODIMM fit the single memory slot in my Acer Aspire One AOD255E-2677?

Yes, the 200-pin DDR2 SODIMM form factor matches the single expansion socket in the Acer Aspire One AOD255E-2677 and D255E-2677 models.

What is the correct way to seat the module so the laptop recognises the full 2GB?

Insert the SODIMM at a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click into the notches on the module.

Does this unbuffered non-ECC stick need any firmware updates or pairing to stay reliable over time?

No firmware or pairing is required; the module runs at 1.8 V with standard CL5 timings and has no heat spreader, so keeping the laptop vents clear is the only ongoing care needed.
