MacBook Pro: How to install memory
Learn how to correctly install memory into a MacBook Pro (all 15-inch and 17-inch models).
Your MacBook Pro computer has two memory slots that you access by removing the memory door in the battery bay. Your MacBook Pro comes with at least 512 megabytes (MB) of 667 MHz Double Data Rate (DDR2) Synchronous Dynamic Random-Access Memory (SDRAM) installed. It may have more memory preinstalled, depending on the configuration you chose when you bought the computer.
Both memory slots can accept an SDRAM module that meets the following specifications:
Double Data Rate Small Outline Dual Inline Memory Module (DDR SO-DIMM)format
1.25 inch or smaller
512 MB or 1 gigabyte (GB)
200-pin
PC2-5300 DDR2 667 MHz Type RAM
Depending on the configuration of the MacBook Pro you purchased, both memory slots may already be full. The maximum amount of memory you can install in your MacBook Pro is 3 GB (see article 304662; using 1 GB DIMM and 2 GB DIMM in each slot).
