Slooooooooow Macbook

The absolute maximum is 3.3 GB, additionally you need to know that by using 2 same RAM sticks, you get some additional performance because of dual channel.

If you're looking to save money, get 1+2 GB, you won't have dual channel, but the difference is really minimal. On the other hand - you can go with 2+2 GB, since it's only 10 bucks and you will know it's maxed out.

thanks for the information, but i quite don't get... does it need to be the same brand? or not??

If you use two sticks of the same capacity (brand is not important, perhaps only in some rare cases will you have problems if you use two different brands of sticks), you get a slight performance advantage because of dual channel.

But as the MacBook can only use 3.3 GB the difference between 3 GB and 4 GB is practically just 300 MB and dual channel (with 2+1 it doesn't work) so the performance gain is very minor.

Hope that cleared things up.

Thanks for all the suggestions.

I did an Archive and Install because everyone here plus the guy on the phone from Apple Care and the guy behind the counter at the Genius Bar suggested it. Result? Parallels was buggered and my iCal calendars got duplicated. (???)

I made a bootable copy of my HD on an external drive with SuperDuper, ran a clean install and then the Migration Assistant. Result? Parallels runs, iCal calendars were untouched and my machine runs about 50% faster but still not nearly as fast as when new with Tiger.

MHO? Archive and Install is a waste of time. Reinstalling will speed things up. Don't upgrade your OS without doing the same to your RAM.

Again, thanks to all!
