System-Specific DDR2 SO-DIMM

This 2 GB module is built for the Acer Aspire One D250 and D150 netbooks. It uses the 200-pin DDR2 SO-DIMM form factor required by those systems. The part number CM256645300SO identifies the exact specification. It is intended for owners of those models who need a memory upgrade.

DDR2 667 PC2 5300 Speed Grade

The decisive specification is the DDR2 667 (PC2 5300) rating with CL5 5-5-5 timings. Only memory matching this speed grade and latency will operate correctly in the target netbooks. A faster or slower DDR2 module will not be compatible. The 1.8 V operating voltage is also fixed for this platform.

Sustained Operation Without Heat Spreader

The module runs unbuffered and without a heat spreader, relying on the netbook's internal airflow. Under continuous workloads the Major Brand Chipset components maintain stability at the rated 667 MHz frequency. The 2Rx8 organisation supports the full 2 GB capacity recognised by operating systems other than Windows 7 Starter.

Questions about this item

What does the 2GB capacity mean for an Acer Aspire One D250 or D150?

This single 2GB module fills the only memory slot, raising total system memory to 2GB with operating systems other than Windows 7 Starter, which is limited to 1GB.

How does the PC2-5300 rating affect usable speed?

The module runs at 667 MHz DDR2; the PC2-5300 designation is the industry name for that speed grade.

Will the 200-pin DDR2 SO-DIMM fit the netbook's memory slot?

Yes, the 200-pin DDR2 SO-DIMM form factor matches the single expansion socket in the Acer Aspire One D250 and D150.
