I found two sticks of ramaxel memory (2gb each) and I want to put it in my MacBook so i can have 4gb. Will it work?
 
What are the specs of those modules?

The stick doesn't say anything but a bunch of serial numbers and PC2-6400S-666, doesn't say what speed it's running at either :/ I'm guessing they came from an HP notebook.

It won't work as it's DDR2 (PC2=DDR2) while your Mac uses DDR3 (=PC3)
