2GB DDR3 SO-DIMM for MacBook Unibody

This 2GB DDR3 SO-DIMM module is built for the 13-inch MacBook Unibody with a 2.0 GHz Core 2 Duo processor. It installs in a single 204-pin slot and runs at 1.5V without ECC or buffering. The stick targets owners of that specific aluminium model who need a direct memory replacement.

1066MHz speed with CL7 timing

Rated at 1066MHz (PC3-8500) and CL7 7-7-7 timings, the module delivers the exact bandwidth the original specification requires. A single stick provides 2GB of capacity; the system accepts two slots for a maximum of 8GB total, so this unit leaves headroom for a second module if more memory is needed later.

Unbuffered 204-pin form factor

The unbuffered 204-pin SO-DIMM fits the MacBook5,1 (A127) logic board without adapters or voltage changes. No heat spreader is included, keeping the profile low for the tight internal chassis. Buyers who need more than 8GB total or who use a different MacBook generation cannot use this module.

Questions about this item

Will this 204-pin DDR3 SO-DIMM run correctly with the original memory already installed in my MacBook5,1?

Yes, the module is specified at 1.5 V, 1066 MHz and CL7 timing, which matches the Late 2008 Unibody MacBook's native DDR3 speed, so it will operate alongside the factory stick without down-clocking.

How can I confirm the stick is recognised at 1066 MHz after installation?

Open About This Mac → System Report → Memory; the new module should appear as a 2 GB DDR3-1066 (PC3-8500) SO-DIMM with 7-7-7 timings.

Does the package contain only the memory stick or are tools and guides included?

The box holds one 2 GB 204-pin DDR3 SO-DIMM; no screwdrivers, anti-static straps or printed manuals are supplied.
