    I'm still going back and forth on getting my macbook and am still not quite ready to pull the trigger yet.

    My question here is if I get the macbook and buy a single 1gb ram stick, will I notice much of a performance hit from not using dual channel? I'm looking to have 2gb in there eventually, but I'm not sure that I'll be able to afford it right away. If I upgrade to 1gb on apple (not a bad price on student store compared to buying 1gb elsewhere) then I'll have the two 512 sticks sitting around being useless.

    Not really. It'll be fine. Go for the MacBook! I picked mine up on Saturday and just ordered 2GB of memory. Can't wait to get it :)

    Having enough memory is loads more fun, than not enough.

    When you don't have enough -- more drive use and a zippy 50-75MB/s.

    Generally you won't probably notice the interleaved memory working, or not.

    But the spinning beach ball, that the VM tends to make appear, you will notice.

    The place it will really hit is video acceleration (or lack thereof). Apple used dual channel because both slots can be addressed at the same time, that way the system and the video chipset aren't fighting over ram as they can both address their own respective banks. I upgraded mine with matching 2 gig sticks and it works great. I can't speak as to how it would work with unmatched pairs, but I wouldn't want to try it. I can only assume that operating in single channel mode might choke up the system while the video and the system wait for memory access.
