MacBook Pro Core 2 Duo 2.53 15" compatible memory

This 8 GB kit contains two 4 GB DDR3 1066 SO-DIMM modules built for the Apple MacBook Pro "Core 2 Duo" 2.53 15" (SD) Mid-2009 model MC118LL/A. It matches the PC3-8500 speed and CL7 timing the system expects.

Fits two SO-DIMM slots with no heat spreader

The 204-pin unbuffered non-ECC sticks install directly into the notebook's two memory sockets. Low-profile chips leave clearance for the factory keyboard and trackpad assembly without requiring any modifications.

Delivers the full 8 GB the platform supports

MacOS X 10.6 Snow Leopard and Boot ROM MBP 51.007E B05 recognise the complete 8 GB capacity across both slots. The DDR3 1066 interface is the ceiling for this architecture; faster or higher-density modules will not operate.

Questions about this item

How much heat does the 1.5V DDR3 kit add under continuous load?

The modules run at standard 1.5V DDR3 voltage with no heat spreader, so they add only the normal thermal load of two 4GB SO-DIMMs in a MacBook Pro.

What boot ROM and OS versions must the MacBook Pro 15" Mid-2009 already have for the 8GB kit to be recognised?

The system needs Boot ROM MBP 51.007E. B05 and Mac OS X 10.6 Snow Leopard or later to address the full 8GB across both slots.
