MacBook Pro (Core 2 Duo): Memory Specifications

The MacBook Pro (15-inch Core 2 Duo) and MacBook Pro (17-inch Core 2 Duo) notebooks have two SDRAM slots in the bottom of the computer, and they come with at least 1 GB DDR2 SDRAM installed into the bottom slot.

Although these notebooks will accept up to a 2 GB SO-DIMM in each of the two memory slots, the MacBook Pro will only support 3 GB total memory. If you want to maximize the amount of SDRAM in your computer, install a 2 GB SO-DIMM in one slot and a 1GB SO-DIMM in the other.

You can use Small-Outline Dual Inline Memory Modules (SO-DIMMS) that meet all of these criteria:

  • PC2-5300
  • unbuffered
  • nonparity
  • 200-pin
  • 667 MHz
  • DDR2 SDRAM

You can use RAM module sizes of 1 GB or 2GB in the top or bottom slots.

DIMMs with any of the following features are not supported in the MacBook Pro (Core 2 Duo) notebooks: registers or buffers, PLLs, ECC, parity, or EDO RAM.

Note: If you do install a 2 GB SO-DIMM in both the bottom and top memory slots of the notebook, the About This Mac window and Apple System Profiler will both show that you have 4 GB of SDRAM installed. However, Activity Monitor and other similar applications will reveal that only 3 GB of SDRAM has been addressed for use by the computer.

Always follow the proper instructions when installing memory:
