Targeted MacBook Pro upgrade

This 8 GB kit is built for the 17-inch MacBook Pro with a 2.66 GHz Intel Core i7 processor. It contains two 4 GB SO-DIMM modules that match the factory memory specification for that model. Installers can populate both slots to reach the machine's maximum supported capacity.

Matched pair simplifies installation

The two modules are sold as a matched kit so they share identical timing, voltage and rank characteristics. Using a paired set avoids the stability issues that can appear when mixing individual sticks of different origin. No extra software or configuration tools are included in the package.

Verify model and slot count first

Confirm the MacBook Pro is the 17-inch 2.66 GHz Intel Core i7 variant before ordering. The system provides two memory slots and supports a maximum of 8 GB total, so this kit fills the available capacity. The modules require 204-pin DDR3 SO-DIMM sockets running at 1.5 V.

Questions about this item

Will the 204-pin DDR3 SO-DIMM modules need any firmware updates or re-seating after long-term use?

No firmware updates are required; the unbuffered non-ECC sticks are plug-and-play. Re-seating is only necessary if the MacBook Pro is moved frequently and the contacts oxidise.

What limit appears first when the 1066 MHz CL7 memory runs continuously at full load?

The memory controller caps bandwidth at the DDR3-8500 spec, so sustained throughput cannot exceed the rated 1066 MT/s regardless of workload intensity.

How much heat and power do the 1.5 V 2Rx8 modules generate inside a 17-inch MacBook Pro during all-day operation?

Each 4 GB stick draws modest power at 1.5 V and has no heat spreader; the laptop's existing cooling handles the thermal load without additional fan noise.
