System-Specific DDR2 SO-DIMM for Acer Aspire One

This 2 GB DDR2 667 MHz module is built for Acer Aspire One Kav60 D250-0Dk and D250-0Dr netbooks. It uses a 200-pin SO-DIMM form factor and runs at 1.8 V with CL5 timing. The unbuffered, non-ECC design fits the single expansion socket in these systems.

DDR2 667 MHz speed ceiling and single-slot limit

The DDR2 667 MHz interface caps bandwidth at PC2-5300 levels, far below modern memory standards. Only one SO-DIMM slot exists in the target netbooks, so total system memory cannot exceed the capacity of this single module. Windows 7 Starter further restricts usable memory to 1 GB regardless of installed hardware.

2 GB capacity in a 2Rx8 unbuffered module

The 2 GB capacity delivered by a 2Rx8 chip organisation is the decisive specification. Buyers whose netbook chipset or BIOS rejects 2 GB modules, or who require ECC or registered memory, cannot use this part. The module is also unsuitable for any system that does not accept 200-pin DDR2 SO-DIMMs.

Questions about this item

Should I choose the 2 GB module or look for a different capacity?

This listing is a single 2 GB stick; the target netbooks have one slot and accept up to 2 GB with most operating systems, though Windows 7 Starter limits usable memory to 1 GB.

What does the 667 MHz rating mean once the module is installed?

The stick runs at 667 MHz DDR2-5300 with CL5 5-5-5 timings at 1.8 V, delivering the standard bandwidth for that generation of SO-DIMM.

Will the 200-pin DDR2 SO-DIMM interface work in my Acer Aspire One D250?

Yes, the 200-pin DDR2 SO-DIMM form factor matches the single expansion socket in the D250-0DK, D250-0DR and related models listed.
