Compatible MacBook Late 2009

This 8GB kit (2 x 4GB) of 204-pin DDR3 SO-DIMM memory runs at 1066 MHz with CL7 timing and 1.5V voltage. It is built for the Apple MacBook "Core 2 Duo" 2.26 13" (Uni/Late 2009) and matches the PC3-8500 standard.

Suits owners of the A1342 MacBook

It fits the MacBook6,1 (MC374LL/A, MC207LL/A) with two slots supporting up to 8GB total. It is not for machines with only one memory slot or for systems requiring registered or ECC modules.

Deciding spec: DDR3-1066 SO-DIMM

The modules use unbuffered, non-ECC DDR3 chips in a 2Rx8 configuration without heat spreaders. Verify your MacBook model is Late 2009 13.3-inch Core 2 Duo 2.4GHz before purchasing.

Questions about this item

Should I choose the 8GB kit or a single 4GB module for my MacBook 13" Late 2009?

The 8GB kit supplies two 4GB modules to fill both slots, reaching the 8GB maximum the Late 2009 MacBook 13" supports. A single 4GB stick would leave one slot empty and cap total memory at 4GB.

What does the DDR3-1066 rating mean once the modules are installed in the MacBook?

The memory will run at 1066 MHz with CL7 timing at 1.5V, matching the MacBook's native DDR3-1066 controller. The dual-channel pair delivers the full PC3-8500 bandwidth the system expects.

Will the 204-pin DDR3 SO-DIMM interface work in my Late 2009 MacBook 13" without issues?

Yes. The 204-pin DDR3 SO-DIMM form factor is the exact slot type used by the MacBook 13" Late 2009, and the kit is validated for that model (MacBook6,1 / A1342).
