MacBook Pro 13.3" DDR3 SODIMM upgrade

This 4 GB module is built for the Apple MacBook Pro 13.3" with an Intel Core 2 Duo 2.26 GHz processor (MC207LL/A). It installs in a 204-pin DDR3 SO-DIMM slot and runs at 1066 MHz with CL7 timing at 1.5 V. The single stick delivers a straightforward capacity increase for that specific model.

Suitable for owners of the named MacBook Pro

Buyers restoring or upgrading the listed MacBook Pro 13.3" will find guaranteed compatibility. The module is unbuffered, non-ECC and uses major-brand chips. It is not for systems that need ECC or registered memory, machines with a different pin layout, or any laptop outside the declared compatibility list.

1066 MHz DDR3 speed rating

The decisive specification is the DDR3 1066 (PC3-8500) rating matched to the target MacBook Pro. The memory operates at 1.5 V with 7-7-7 timings in a 2Rx8 configuration. If the host requires a different DDR generation, voltage or speed grade, this module will not work.
