Targeted MacBook Pro upgrade

This 8 GB kit contains two 4 GB DDR3 1600 SO-DIMM modules built for the Apple MacBook Pro "Core i7" 2.3 15" Mid-2012. It matches the factory PC3-12800 specification and uses the required 204-pin form factor. Unbuffered, non-ECC chips with CL11 timing drop straight into the two memory slots. Buyers needing more than 16 GB total capacity cannot use this kit.

Standard voltage and passive cooling

Each module runs at the stock 1.5 V with no heat spreader, relying on the notebook's existing airflow. Power draw stays within the original DDR3 1600 envelope so thermals and fan behaviour remain unchanged. The unbuffered 2Rx8 layout adds no extra electrical load. Systems that require registered or ECC memory will not accept these sticks.

Two-module kit with lifetime warranty

The package delivers exactly two memory sticks so both slots are filled in a single step. Computer Memory Solutions backs the modules with a limited lifetime warranty when purchased directly from them. No software, drivers or additional accessories are included. Users who prefer a single 8 GB stick or need ECC support must look elsewhere.

Questions sur cet article

How do I install the two 204-pin DDR3 SO-DIMM sticks into my Mid-2012 MacBook Pro, and which step do people often miss?

Remove the bottom case, release the clips on both occupied slots, swap the existing 2 GB modules for the two 4 GB sticks, press each firmly until the clips click, then replace the case; the step most often missed is pressing hard enough to fully seat both modules.

Will these 1.5 V unbuffered DDR3 modules need any maintenance or replacement during the laptop's life?

No routine maintenance is required; the memory is solid-state with no moving parts, so it typically lasts the useful life of the MacBook Pro unless physical damage occurs.

What is the first limit I will hit under sustained heavy workloads with this CL11 1600 MHz kit?

The 8 GB total capacity (2 × 4 GB) is the first bottleneck; macOS will begin swapping to storage once the working set exceeds the installed memory.
