16 GB DDR3 SO-DIMM kit for 17-inch 2011 MacBook Pro

This 16 GB kit contains two 8 GB DDR3 1333 MHz SO-DIMM modules built for the Apple MacBook Pro 17-inch Late 2011 with a 2.4 GHz Core i7 processor. It raises the memory ceiling to 16 GB across the two available slots, even though Apple's original specification lists an 8 GB maximum. The modules run at 1.5 V with CL9 latency and use unbuffered, non-ECC chips.

Tool-free installation with standard SO-DIMM slots

Installation requires opening the bottom case and pressing each 204-pin module into the SO-DIMM slots until the side clips engage. No drivers or firmware updates are needed; the system recognises the new capacity on the next boot. The most common issue is a module not fully seated, which results in a boot chime sequence or a blank screen until both sticks are pressed in firmly.

Steady throughput for long work sessions

Under sustained load the DDR3 1333 MHz memory maintains its rated CL9 timing without throttling, because the modules have no heat spreader and rely on the MacBook's internal airflow. Continuous multitasking, virtual machines or large media projects stay responsive as long as the notebook's cooling system keeps the chassis temperature in check. The 2Rx8 organisation provides full dual-channel bandwidth for the duration of the workload.

Questions about this item

How can I confirm the 16GB kit is running at 1333MHz CL9 after installing it in my MacBook Pro 17" Late 2011?

Open System Report or About This Mac and check the Memory tab; each slot should show an 8GB DDR3 1333MHz module with 9-9-9 timing and 1.5V voltage.

What comes in the package and is anything else required for installation?

The box contains two 8GB 204-pin DDR3 SO-DIMM sticks; no additional parts or tools are needed for the two memory slots in this MacBook Pro model.

Should I choose the 16GB (2x8GB) DDR3 1333MHz kit or a different capacity for my MD311LL/A?

This 16GB kit matches the maximum supported memory for the Core i7 2.4 17" Late 2011 and fills both sockets with matched 8GB modules.
