MacBook Early 2009 memory kit

This 8 GB kit contains two 4 GB DDR2 667 MHz SODIMM modules built for the Apple MacBook (13-inch, Early 2009) with model ID MacBook5,2 and order number MB881LL/A. It suits owners of that specific notebook who need the maximum supported memory for everyday multitasking.

DDR2 667 MHz bandwidth ceiling

The PC2-5300 interface tops out at 667 MHz, so data throughput is limited to the bandwidth of that generation. Systems requiring faster memory or newer DDR standards cannot use these modules, and the 200-pin form factor will not fit later MacBook slots.

Straightforward SODIMM installation

Installation involves opening the battery bay, removing the existing modules, and seating both 200-pin sticks until they click. The main risk is inserting a module at an angle or mixing different speeds, which prevents the MacBook from booting.

Questions about this item

Should I choose the 8GB kit with two 4GB modules or a single 8GB stick for my Early 2009 MacBook?

The Early 2009 MacBook has two SODIMM slots and supports a maximum of 8GB total. This kit provides two 4GB modules to fill both slots and reach that limit.

What does the PC2-5300 rating mean for actual performance in my MacBook5,2?

PC2-5300 indicates a peak transfer rate of 5300 MB/s at 667 MHz. The MacBook5,2 memory controller runs at this speed, so the modules operate at their rated specification.

Will the 200-pin DDR2 SODIMM interface limit the bandwidth I can use?

The 200-pin DDR2 SODIMM form factor carries the 667 MHz signal. The MacBook5,2 chipset caps memory throughput at the PC2-5300 level, matching these modules exactly.
