    Hi All,

    Just a quick question. I recently picked up a latest gen Macbook White Unibody (MC516LL/A, the last one Apple made) locally for a good price to get back into Macs and test out Lion.

    It came with the default 2GB of DDR3 RAM (2x1GB sticks) which I tried to upgrade to 4GB / 8GB (2x2GB or 2x4GB sticks, respectively) with some spare RAM I have from Dell laptops. These are all DDR3-1333 (or PC3-10600) whereas the original RAM is DDR3-1066 / PC3-8500. I never had problems with putting DDR3-1333 in any Macbook Pros I had prior, this is the first time I'm having issues. The Macbook would just make continuous 1beep cycles and a black screen.

    Is the MC516LL/A only compatible with the slower DDR3-1066 RAM? :(

    This is the exact same one I have.


    It shows it uses the 1066MHz chips.
    I have 2X2Gigs RAM and looking to upgrade to 2X4Gigs RAM soon.

    Yea, thing is, I had a Macbook Pro 13" 2010 version (similar specs as this white Unibody Macbook I have: Core 2 Duo 2.4GHz, nVidia 320m video):

    Macbook Pro 13" 2010: MC374LL/A

    which shows it uses 1066MHz chips as well, but I never had an issue putting 1333MHz chips RAM into it. Oh well, whatever, maybe since this unit I have now is a "cheapie Macbook non-Pro" Apple lamed out on the Motherboard. I just ordered some 1066MHz DDR3 RAM online. Thanks for your input!

    As an aside, I just sold my Dell Vostro 3450 that is, spec-wise, 10000% superior to this Macbook White Unibody I just got. I sold the Dell to use the same $$ to buy this Macbook. Its still kinda hard to stomach downgrading in specs from a:

    Core i5-2410m
    6GB RAM
    500GB, 7200RPM HDD
    ATI Radeon 6630m 1GB dedicated graphics
    2x USB 3.0 ports, 1x USB+eSATA combo port, Native VGA and HDMI ports
    Backlit keyboard


    Core 2 Duo
    2GB RAM
    250GB, 5400RPM HDD
    nVidia GeForce 320m integrated graphics
    2x USB 2.0 ports, 1x mini-Displayport (requires optional dongles!)
    non-backlit keyboard

    I forgot how much of a premium Apple laptops cost. I figure I already have a pretty beefy Windows Gaming laptop so might as well keep a Mac around for OSX. Besides, the all-glass button-less trackpads on the newer MBP's and MB's still cannot be beat.

    Yeah, I have no idea about it. This is my first Apple system to purchase.

    I too sold my Dell 1545 for 500.00 and used that (plus 150) to get my Macbook and it came with a Magic Mouse, 4Gigs of RAM, and a Mini-DVI to HDMI.

    My Dell was smoking fast with a nice resolution and I dreaded going to a smaller resolution. But, this far, I'm 100% happy with it. For what I do, it's fast enough. I don't do any big image and video editing (Used iMovie for the first time on it.) or anything that would actually utilize what it has or anything more.

    I will upgrade to 8Gigs of RAM but, that's for virtuals. I'll have XP, Win7Pro and Win08R2 installed for testing and Packet Tracer. :)

    I'm sure you will enjoy it, please post your thoughts after a few weeks of using it.
