Owners of the listed Aspire One models needing

The module matches the single expansion socket and the 2 GB maximum supported by these systems. Buyers with other laptops, desktops or netbooks that use a different pin count, voltage or DDR generation cannot use this part. It is also unsuitable for anyone requiring ECC or registered memory.

Single 200-pin DDR2 667 MHz SO-DIMM at 1.8 V

This specification determines physical and electrical fit in the target Aspire One. The 200-pin DDR2 interface, 667 MHz speed and 1.8 V operation must match the socket and chipset requirements exactly. Systems with a different pin layout, voltage or memory standard will not accept the module.
