4GB DDR3 SO-DIMM for Acer Aspire One

This 4GB DDR3 1066 MHz SO-DIMM module is built for the Acer Aspire One AO725-0687 and AOD725-0687 netbooks. It uses a 204-pin unbuffered design running at 1.5V with CL7 latency. The single stick expands the compatible system to its maximum supported memory per socket.

Ideal for restoring specific netbook models

Owners of the listed 11.6-inch Acer netbooks needing a direct replacement or a full 4GB upgrade will find guaranteed compatibility. Builders working on any other laptop, desktop, or server platform cannot use this module due to its system-specific validation and SO-DIMM form factor.

DDR3 1066 speed rating determines fit

The module operates strictly at the PC3-8500 1066 MHz specification with 7-7-7 timing. Systems requiring a different memory speed, voltage, or pin count will not accept this part. Verify the exact model number before ordering.

Questions about this item

Should I choose the single 4 GB stick or a different capacity?

The module is sold as a single 4 GB stick; the Acer Aspire One AO725-0687 only accepts one SO-DIMM and the maximum per socket is 4 GB, so this capacity fully populates the slot.

What does the 1066 MHz speed rating deliver in the netbook?

The DDR3 1066 (PC3 8500) rating matches the memory controller of the AMD C-70 processor, so the stick will run at its rated 1066 MHz without down-clocking.

Does the 204-pin DDR3 SO-DIMM interface limit bandwidth or latency?

The 204-pin DDR3 SO-DIMM form factor carries the 1066 MHz / PC3 8500 signal with CL7 timing, which is the native ceiling for this platform.
