    I recently upgraded my 2006 Macbook to a new 500gb hard drive and 2gb memory.

    My only worry is that I didn't use two 1 gig memory cards but just one 2 gig memory card. Will that really have any adverse affects to my macbook?

    Also anything I before late 2007 macbooks I believe can only take 2gb and afterwards its the 4 so I don't know if I could put in that second 2gb.

    Late 2006 MacBooks can take 4GB (but only see 3). If you have a Core Duo model, I doubt the 2Gig stick will work. Should be fine if you have a Core 2 Duo (late 2006). I know that Core Duo minis have fits when using 2GB sticks.

    Mine is a middle 2006 and I am currently running it on only the one 2 gig stick. I am just worried about any problems I could have down the road especially if it could be soon.

    If it works your probably OK but you are losing 5% of the speed by not having dual channel.

    Personally, I would always go with a single 2 GB stick. In my mind, the minor speed loss is more than compensated for by the possibility of upgrading in the future without having to replace the two 1 GB sticks.

    Awesome thank you guys for the info. I am just going to stick with the 2 gig I have in now so I dont have to spend the money for 2 replacement 1 gigs.

    He won't ever be able to upgrade. The max his MacBook can take is 2GB. 2X1GB would have been the best route for his machine as it max's both the memory and the speed.

    Yeah? Is that Apple's limit or the real limit? If so, than 1 GB would definitely be the way to go.

    For a Core Duo machine, that's the hard limit (and Apple's). My mini goes berserk if I try a 2G stick so its interesting that the OPs MacBook doesn't since its almost identical hardware but 2G is definitely the limit.

    Yeah, it struck me as strange that it would work at all with 2 GB if if doesn't support 4 GB in two slots. I don't know that much about the specifics of hardware, though, so I'll yield to your judgement.

    My machine works fine no problems at all. It says by the memory slot that 2 is the preferred but I have not yet run across any problems with just the 1 card in there.
