2 GB DDR2 SO-DIMM for Acer Aspire One D255

This 200-pin DDR2 SO-DIMM delivers 2 GB of system memory at 667 MHz with CL5 timing. It is built specifically for the Acer Aspire One D255-2691 netbook and matches the PC2 5300 specification. The unbuffered, non-ECC module installs directly into the single expansion socket.

Low-voltage operation keeps thermals modest

Running at 1.8 V, the stick draws minimal power and produces little heat inside the compact chassis. No heat spreader is fitted, so airflow from the system fan is sufficient for normal workloads. The low voltage also helps preserve battery runtime on the netbook platform.

Single-stick kit simplifies the upgrade

The package contains one 2 GB module, allowing the owner to reach the 2 GB maximum supported by operating systems other than Windows 7 Starter. No additional cables, brackets or software utilities are included. The lifetime warranty from Computer Memory Solutions covers the module itself.

Questions about this item

How do I install this 200-pin DDR2 SODIMM in my Acer Aspire One D255-2691, and what step do people often miss?

Power off, remove the battery, open the memory cover on the bottom, insert the module at an angle until the gold contacts are hidden, then press down firmly until both side clips click; the step most often missed is pressing down hard enough to engage both clips.

Will this 2GB DDR2 667MHz module need any maintenance or replacement later?

No routine maintenance is required; the module has no heat spreader and no moving parts, so it only needs replacement if it fails or if you upgrade the netbook beyond its 2GB maximum supported memory.

What limit appears first when this memory runs under sustained load in the Acer Aspire One D255-2691?

The system chipset caps usable memory at 2GB total, so the capacity limit is reached immediately; thermal throttling of the netbook's processor typically becomes the next bottleneck during extended heavy use.
