We need to know your EXACT machine to be able to give you a definitive answer. It varied in the A1181 models. Go here and enter your serial number to find out: http://www.everymac.com/ultimate-mac-loo… UPDATE Standard RAM: 2 GB Maximum RAM: 6 GB* Details: 2 GB of RAM is installed as two 1 GB modules, no slots free. *Apple officially supports a maximum of 4 GB of RAM but third-parties have been able to upgrade the system to 6 GB of RAM using one 2 GB and one 4 GB memory module. * RAM Type: PC2-5300 DDR2 Min. RAM Speed: 667 MHz To save a little cash, if it has two 1GB sticks, replace just one of them with a 4GB and take it to 5GB.
