Q: I have a macbook pro 2007 1,1. How much ram will it support?

As to your type question: (two SO-DIMMs of) 667MHz DDR2 SDRAM (PC2-5300); the two SO-DIMM slots support up to 4GB.

No, the model 1,1 1.83Ghz Core Duo can only use 2gb of RAM.

These are good online stores for Mac compatible RAM

OWC http://eshop.macsales.com/shop/memory/MacBook/DDR2/ - They offer Mac tested RAM at very good prices.

Crucial Memory http://www.crucial.com/ - good place to buy RAM from all over the world. They also have an excellent memory selector that allows you to choose memory based on your computer's model

Data Memory Systems http://www.datamemorysystems.com/apple-memory.asp - another good, cheap place to buying RAM if you live in the U.S.

He is correct, one SO-DIMM in the early 2007 edition. Still the same type of ram.

No, two slots, each taking one 1gb RAM stick. Although you can use one 2gb stick and leave the second slot empty.

Yes.

Ciao.

Thanks.

Keep in mind that OS X Snow Leopard 10.6.8 is the highest OS X you will be able to run. The Core Duo is a 32-bit processor and SL is the last 32-bit Mac operating system.

At the pace of today's technology, in the eyes of Apple a 2007 Core Duo-based MacBook is quite old by now, "obsolete".
