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.
