    I've looked over the guides and didn't see anything covering this. Also I checked the threads and didn't find this topic so if this is a well trodded noob question - I apologize.

    I just upgraded my MacBook (2.2ghz Santa Rosa) from 1GB to 4GB using Kingstons 4GB upgrade kit (guarenteed 100% compatible, info shows it as 4GB of 667mhz DDR, which as is my understanding as fast as the FSB will go).

    Running xbench before and after I saw an almost negligable increase. Even after multiple runs the gain isn't what I'd consider statistically significant - it's low enough to be noise.

    Here's my benchmarks:

    Can anyone shed some light on this for me? Is this $100 misspent? Is Xbench not a good benchmark tool for this? Actually, if I had got it in store - would this have been $800 misspent as well?

    More RAM doesn't make a computer faster by itself. The biggest benefit of more RAM is that the OS doesn't have to swap to the disk as often. This in turn will make the system 'faster' in that RAM is much faster than reading/writing to the harddrive. In laptops the harddrive is also slower, usually 5400rpm.

    Where you will see the biggest benefit is in using applications. Now you can not only have more apps open (without slowing the system down), but each app can use more of that RAM.

    It was definitely money well spent. Use your computer for a while and see how it goes.
