How much RAM can my macbook take? please help!

More than likely it's 3 GB. You could try and install 4 GB, but it's supposed to cap off the amount used at just over 3 GB.

Apple only officially supported 2 GB for the MacBooks of your vintage and earlier.

If you own a core 2 duo which it sounds like you do it will hold 4 GB of RAM but only use 3 GB of RAM. The 4 GBs gives best video response by giving you a matched pair. Crucial has their site set up to sell exactly what RAM amount is specified by Apple.

You can see results of tests that were run with the different RAM configurations.

The only MacBook that can't hold or use more than 2 GB was the Core Duo MacBooks.

The "official" support is only for 2 GB. The evidence from people who have tried is that approximately 3GB is the actual maximum. You could either drop in a 2GB and a 1GB, although 2 2GB modules will supposedly work with part of the memory unused. The OS can only use 3 GB but I think one of the reporting mechanisms will say 4 GB.

Crucial.com only sells modules through their memory selection tool that corresponds to officially supported configurations.

It's 3GB. Apple says it is 2, but it's really 3.
