Apple MacBook Core 2 Duo upgrade

This 4GB kit delivers two 2GB DDR2 667 SO-DIMM modules built for the late 2006 white MacBook 13 inch model A1181. It targets owners of that specific machine who want the maximum memory the platform allows. The unbuffered non-ECC design matches the original specification exactly.

200-pin SO-DIMM slot fit

Each stick uses the standard 200-pin DDR2 SO-DIMM form factor required by the MacBook's two memory sockets. No heat spreader is present so the modules sit flush under the factory door. Installing the pair fills both slots and frees the system from the original 1GB or 2GB limit.

Low voltage quiet operation

The modules run at 1.8 volts with CL5 5-5-5 timing producing minimal heat and no audible noise in normal use. Power draw stays low because DDR2 667 operates well within the laptop's original thermal envelope. No extra cooling or airflow changes are needed.
