Compatible MacBook Pro Upgrade

This 16 GB kit is built for the Apple MacBook Pro 15 inch 2.3 GHz i7 Quad Core model MD103X/A. It replaces the factory memory with two matched modules so the notebook can reach its maximum supported capacity.

1333 MHz DDR3 Specification

The decisive figure is the DDR3 1333 (PC3 10600) speed rating paired with CL9 9-9-9 timing at 1.5 V. Only modules matching this exact data rate and voltage will operate correctly in the target system.

204-Pin SO-DIMM Fit

Each 8 GB stick uses the standard 204-pin SO-DIMM form factor and is unbuffered, non-ECC, dual-rank 2Rx8. The pair fills both memory slots, leaving no room for additional modules and requiring no extra cooling hardware.

Questions about this item

What does the 1333 MHz DDR3 rating actually deliver inside a MacBook Pro 15 inch 2.3 GHz i7?

The kit runs at 1333 MHz DDR3 (PC3-10600) with CL9 9-9-9 timing and 1.5 V, giving the maximum memory bandwidth the platform supports.

Which slot standard does the 204-pin SO-DIMM use and what does that limit?

It uses the 204-pin DDR3 SO-DIMM interface, which is keyed for DDR3 only and caps transfer rates at the 1333 MHz PC3-10600 level.

Will the two 8 GB sticks physically fit the MacBook Pro 15 inch Md103X/A with no free slots?

Yes — each module is a standard-height 204-pin DDR3 SO-DIMM, and the kit provides exactly two sticks to fill both sockets.
