2GB DDR3 SODIMM for Acer Aspire One D255E-13639

This 2GB DDR3 1066MHz SO-DIMM is built specifically for the Acer Aspire One D255E-13639 netbook. It targets owners of that exact model who need to replace a failed module or reach the system's maximum supported memory. The single 2GB stick fills the sole expansion slot.

Direct slot insertion with one SODIMM

Installation requires opening the memory compartment and pressing the 204-pin module into the single SODIMM socket until the retaining clips engage. The unbuffered, non-ECC design matches the original specification. The main risk is purchasing this kit for a different laptop, as the system-specific validation only covers the listed Acer model.

DDR3 1066 speed ceiling and single-slot limit

The DDR3 1066 (PC3 8500) interface caps data rates at 1066MHz with CL7 timing at 1.5V. The netbook provides only one memory socket, so total capacity cannot exceed this 2GB module. Builders needing more memory or a faster memory standard must choose a different platform entirely.

Questions about this item

How can I confirm the CM256648500SO is running at 1066 MHz after installation?

Open Task Manager, go to the Performance tab, select Memory and verify the speed reads 1066 MHz; you can also check the SPD tab in CPU-Z to see the PC3-8500 rating and CL7 timing.

What comes in the box and what else is needed for the Acer Aspire One D255E-13639 upgrade?

The package contains one 2 GB 204-pin DDR3 SODIMM stick; the laptop has a single memory socket supporting up to 2 GB, so no additional modules or tools are required.

Which capacity should I choose for the D255E-13639 if the maximum supported memory is 2 GB?

Select the 2 GB module — it matches the system's maximum capacity and fills the only available slot, giving the full 2 GB upgrade in one step.
