8GB DDR3 SODIMM for 2011 MacBook Pro

This 8GB DDR3 1333MHz SODIMM module is built for the 13.3-inch MacBook Pro released in late 2011. It uses a 204-pin unbuffered design with CL9 timings and runs at 1.5V. The single stick adds 8GB of system memory to the compatible notebook.

Suits 13.3-inch Late 2011 models only

Owners of the specific MacBook Pro 13.3-inch Late 2011 (MD313LL/A, A1278) can install this module for a straightforward upgrade. Buyers with any other MacBook size, year, or model family cannot use this SODIMM and should look for memory matched to their exact machine.

204-pin DDR3 SO-DIMM interface

The module conforms to the 204-pin DDR3 SO-DIMM standard required by the target MacBook Pro. A different pin count or DDR generation will not fit the socket or function in this system.
