    hi all, i am now considering upgrading my macbook's ram, but am tied between 2GB n 3GB.

    to my understanding, if i do 3GB total ram i wont get dual channel right? so would it be wiser to just leave it at 2GB? i do not use heavy applications, i usually just msn, surf the web and maybe play some games that arent that graphic intensive.

    anyways, 2GB or 3GB?

    pros for 2GB:
    -cheaper than configuring for 3GB
    -dual channel

    pros for 3GB:
    -faster than 2GB (haha is this a no brainer?)

    anyways i read the very useful understanding intel mac ram guide already, so just wondering what is better (considering my needs)

    will the macbook 2.16 even recognize over 2gb of ram? I thought only the newer 2.2 macbook could have 4gb of ram.

    Sorry,
    I do not think it will go over 2 GB then. Are 1.5 GB sticks produced?

    I believe 3 gb is out of the question. Go to 2gb.

    The more RAM the better, whatever the case. Even though you won't be using dual-channel, OS X will still use all the RAM it has access too. Look at the bottom of this BareFeats page: http://www.barefeats.com/mbcd6.html

    I'm planning on putting 3GB in my 17" C2D MacBook Pro. You can find a 2GB stick for $73 now at OWC.

    that is what i am thinking. so regardless of what i am doing with my macbook, if i have 3GB on my mac, it will use all 3GB of it right? i wish barefeats did an overall speed increase test comparing 2GB n 3GB

    The 2.16 is a Core2Duo
    It will support 2 + 1 Gb
    or 2 + 2 Gb, but will only allow the OS to use 3 Gb of the 4 Gb total.

    Slight misconception here -- the performance increase from 2 to 3 GB depends more than anything on the programs you are running. If you are just running Mail, there will be little or no improvement 2 Gb vs. 3 Gb because you are not exceeding the 2 Gb level, so there's no advantage.

    But if you are multitasking heavily and switching frequently between more than 2 Gb worth of programs, or have iPhoto with 1000's of photos, or doing digital audio or video, then the 3 Gb will pay off. Photoshop and a few other programs manage their own scratch disk space, and can address up to 3 Gb of memory, so they will show speed increases.

    More MacBook benchmarks with various RAM configurations. Note how little difference dual channel makes. For the money, 3 GB seems to be the sweet spot. You can actually install 4 GB, but only about 3.3 GB will actually be used due to a lack of available registers, or something like that.
