MacBook 13" Unibody Memory Upgrade

This 8 GB kit contains two 4 GB DDR3 SO-DIMM modules built specifically for the Apple MacBook "Core 2 Duo" 2.4 13" Unibody from late 2008. It targets owners of that model who need the maximum 8 GB capacity the two slots allow. Builders working on any other platform cannot use this memory.

Thermals Noise and Power Draw

Unbuffered DDR3 modules without heat spreaders run at the standard 1.5 V and produce minimal heat inside the tight Unibody chassis. The memory adds no audible noise because it has no moving parts. Power draw remains within the original system specification for SODIMM slots.

CL7 Timing at 1066 MHz

Rated at DDR3 1066 (PC3 8500) with CAS latency CL7 and 7-7-7 timing, these sticks match the factory memory speed the MacBook requires. Faster or slower modules would not keep the system stable. The CL7 figure is the single specification that decides whether this kit works correctly in the target notebook.

Questions about this item

How do I install the 204-pin DDR3 SO-DIMM modules into my MacBook 13" Unibody 2.4, and what step is often missed?

Remove the bottom case, release the retention clips on both slots, insert each 4 GB stick at an angle until the gold contacts disappear, then press down firmly until the clips snap shut; the step people skip is seating both modules completely before replacing the case.

What maintenance or replacement will this 8 GB kit need over time?

No routine maintenance is required; the unbuffered non-ECC DDR3 modules have no moving parts, so replacement is only necessary if a stick fails or you upgrade to a system that supports more memory.

What limit appears first when the memory runs at 1066 MHz under sustained load?

The CL7 7-7-7 timing at 1.5 V sets the latency floor; bandwidth is capped by the PC3-8500 rating, so throughput limits appear before thermal throttling on these heat-spreader-less modules.
