Is it possible to use 6GB of memory in my MacBook Pro 3,1? The specifications of my MacBook Pro say the maximum memory supported is 4GB using two 2GB DDR2 667MHz each.

However, some say that this model can support up to 6GB of memory, putting a 4GB Memory DDR3 1066MHz in one of the slot and 2GB (or 4GB, 6GB directing in this case memory).

The bus is 800MHz MacBook Pro. How should I install memory in the two memory slots to get the highest memory capacity and performance in my MacBook Pro?
Yes. I own a MacBook Pro 3,1. I installed 6GB memory and have been using it like that for more than two years. Note the specifications below. You can call the tech support people at Other World Computing if you have any questions.

The RAM in my system is as follows:


Bank 0: 2GB DDR2 SDRAM 667 MHz
Bank 1: 4GB DDR2 SDRAM 667 MHz
