Computer Memory Solutions CM256645300SO 4GB (2×2GB) DDR2 667 memory upgrade

Compatible Acer Aspire One upgrade

This DDR2 SO-DIMM kit is built for Acer Aspire One Kav50, Kav60, Nav50 and Nav60 notebooks. It delivers 4GB total capacity across two 2GB modules that match the factory 200-pin layout. The unbuffered, non-ECC design installs directly into the two available sockets without configuration changes. It suits owners of these specific models who need the maximum memory their chipset accepts.

4GB kit with 3.5GB usable ceiling

Each module runs at 667 MHz with CL5 5-5-5 timing at 1.8V. The platform recognises up to 4GB installed, yet the system may report 3.5GB or less once hardware reservations are applied. A 64-bit operating system is required to address the full range. The kit fills both slots, so no further internal expansion is possible on these notebooks.

Low-voltage DDR2 thermals

Operating at the standard 1.8V for DDR2, the modules draw minimal power and produce little heat in normal use. No heat spreader is fitted, relying on the notebook’s existing airflow. The unbuffered design adds no extra electrical load, keeping acoustic impact negligible in the compact chassis.
