2GB DDR3 1066 SODIMM for Acer Aspire One

This 2GB DDR3 1066 (PC3 8500) SO-DIMM is built to the exact specifications of the listed Acer Aspire One D255E models. It arrives new from Computer Memory Solutions as a single 204-pin unbuffered module rated at 1.5V with CL7 7-7-7 timings and a 1Rx8 rank configuration.

Suits owners of the named netbooks.

The module is validated for Acer Aspire One D255E-13410, D255E-13429, D255E-13444 and the additional part numbers shown in the compatibility list. Buyers with different laptops, desktops, or netbooks that require another pin count, voltage, speed, or maximum capacity should look elsewhere.

204-pin DDR3 SO-DIMM form factor decides fit

Only systems with a 204-pin DDR3 SO-DIMM slot running at 1.5V can accept this stick. The physical key notch and electrical signalling are specific to this generation, so the module will not seat or function in slots built for any other memory type.

Questions about this item

Will the 204-pin DDR3 SODIMM need any firmware updates or periodic replacement after installation?

The module is a passive component with no firmware; it requires no updates and no scheduled replacement under normal use.

What limits performance first when the Acer Aspire One D255E-13410 runs memory-intensive tasks all day?

The 2 GB capacity and single 1Rx8 rank saturate before the DDR3-1066 CL7 timing becomes a bottleneck.

How much heat and power does the 1.5 V DDR3 stick add when the netbook runs continuously?

At 1.5 V without a heat spreader the module draws minimal power and stays cool enough for the chassis fanless design.
