Compatible MacBook Memory Upgrade

This 2 GB DDR3 1066 MHz SO-DIMM is built for specific Apple MacBook and MacBook Pro models listed by the supplier. It uses a 204-pin unbuffered non-ECC design with CL7 timing at 1.5 V. Buyers who need higher capacity modules or a different memory generation cannot use this stick.

Thermals Noise and Power

The module runs at the standard 1.5 V DDR3 voltage without a heat spreader. Passive cooling relies on the notebook’s internal airflow so acoustic output stays at the system’s normal level. Power draw follows the PC3 8500 specification for this density and speed.

Single Module Package Contents

The box contains one 2 GB memory stick backed by a limited lifetime warranty from the manufacturer when purchased directly. No additional cables, tools or software are included. The guarantee covers compatibility with the exact MacBook models identified in the description.

Questions about this item

How do I install the 204-pin SO-DIMM into my MacBook, and what step is often missed?

Power off, unplug, and remove the battery if accessible. Open the memory door, align the notch on the 204-pin DDR3 stick with the slot key, insert at an angle, then press down firmly until both side clips click. The step often missed is not pressing hard enough to engage both clips, leaving the module loose.

What maintenance or replacement will this 2GB DDR3 module need later?

No scheduled maintenance is required for the unbuffered non-ECC memory. If errors appear, run Apple Hardware Test or MemTest86 to confirm a fault; the stick would then need replacement. Dust can be cleared with compressed air when the case is open for other upgrades.

What limit appears first under sustained use with this CL7 1.5V DDR3-1066 SO-DIMM?

The 2GB capacity is the first bottleneck; macOS and modern apps will exhaust it before the 1066MHz speed or CL7 latency becomes the limiting factor. Thermal throttling is unlikely because the module has no heat spreader and runs at standard 1.5V.
