MacBook Pro 15" Mid-2012 Memory Kit

This 8 GB kit contains two 4 GB DDR3L 1600 SO-DIMM modules built for the Apple MacBook Pro "Core i7" 2.6 15" Mid-2012. It uses the 204-pin form factor and runs at 1.35 V with CL11 timing. The upgrade targets owners of that specific model who need the maximum 16 GB capacity across two slots.

Straightforward SO-DIMM Installation

Installation follows the standard MacBook Pro memory access procedure: remove the bottom case, release the retaining clips, and seat each 204-pin module until it clicks. The low-profile design has no heat spreader, so clearance issues are unlikely. The main risk is inserting a module at an angle or mixing voltages, which can prevent the system from booting.

Steady Operation at 1.35 V

Under sustained workloads the DDR3L modules maintain their 1600 MHz speed at the rated 1.35 V without throttling. Unbuffered, non-ECC 1Rx8 organisation delivers consistent bandwidth for long renders or virtual-machine sessions. The absence of a heat spreader means the chassis airflow handles thermal load, so performance stays stable as long as the notebook cooling is functional.

Questions about this item

How can I confirm the 1600 MHz DDR3L kit is running at the correct speed after installing it in my MacBook Pro 15" Mid-2012?

Open "About This Mac" and click "System Report". Under Memory, each 4 GB module should show 1600 MHz and 1.35 V.

What does the 8 GB kit include and is anything else required for installation?

The box contains two 4 GB 204-pin DDR3L SO-DIMM sticks. No extra parts or tools are needed beyond the MacBook's bottom-case screws.

Should I choose this 8 GB (2×4 GB) kit or a different capacity for my MacBook Pro 15" Mid-2012?

This kit fills both slots for 8 GB total. The system supports up to 16 GB, so select a 2×8 GB kit if you want the maximum capacity.
