System-Specific DDR3 Kit
This 4 GB kit contains two 2 GB DDR3 SO-DIMM modules rated at 1066 MHz with CL7 timing. It is built for the Apple MacBook Pro 13.3" Intel Core 2 Duo 2.26 model MC207LL/A. The unbuffered, non-ECC design uses 1.5 V power and major-brand chips.
Verify Slot Count And Maximum
Confirm the notebook has two SO-DIMM sockets and supports 8 GB total memory before ordering. The existing modules must be removable and the system must accept PC3-8500 204-pin DDR3 at 1.5 V. Machines with soldered memory or a lower ceiling will not use this kit.
Drop-In Upgrade For Two Slots
The pair fills both sockets to reach the 8 GB ceiling, freeing the system from swapping and improving multitask response. No heat spreader is fitted, so standard low-profile clearance applies. Installation requires only a screwdriver and the standard MacBook memory door.
