System-Specific DDR3 Kit

This 8 GB kit contains two 4 GB DDR3 SO-DIMMs rated at 1333 MHz with CL7 timing and 1.5 V operation. It is built for the Apple MacBook Pro 13.3" Core i5 2.4 (Late 2011, MD313LL/A, A1278) and uses the 204-pin form factor required by that model.

Compatibility Focus

The modules are validated for the specific MacBook Pro identified as MacBookPro8,1 and support a total of 16 GB across its two slots. Buyers with a different Mac model, a newer macOS-only machine, or any non-Apple laptop should not use this kit.

Deciding Specification

The critical match is DDR3 1333 (PC3 10600) SO-DIMM at 1.5 V in a 204-pin unbuffered non-ECC package. If the target system requires a different voltage, pin count, speed grade or memory generation, this kit will not fit or function.

Soalan tentang produk ini

Will the 1333 MHz CL7 modules work with the original memory still installed in my MacBook Pro 8,1?

The kit is guaranteed compatible with the MacBook Pro 8,1 (MD313LL/A, A1278) and uses the 204-pin DDR3 SO-DIMM form factor required by that model.

How can I confirm the 8 GB kit is running at 1333 MHz with CL7 timings after installation?

Open System Report in macOS and check the Memory section; it will show each 4 GB module at 1333 MHz with 7-7-7 timing and 1.5 V voltage.

What comes in the box and do I need any extra parts to install the two 4 GB sticks?

The package contains the two 4 GB DDR3 SO-DIMM modules only; no tools or additional components are required for installation in the MacBook Pro.
