    Hello Guys,


    Apparently I got a very good deal on two 8gb sticks (much lower than $1,500) and was wondering if this can be done:

    I currently have an Imac (2010) and a MPB 17 (2011) I know both support 16gb of ram... but I wish to have 10gb in ram in both since 16gb seems excessive to me... soo is it possible to just remove one 2gb stick from each and put an 8gb in place making it 8gb + 2gb modules??

    I want to avoid the possibility of Kernel Panics, Slowdowns or anything that might make the computer not work as best as it can... So can this be done without a glitch?

    Thx!
    JC

    BTW sticks are same specs as oem

    Just put 2x8GB in the MBP and buy 2x4GB for the iMac to make its RAM 12GB. At least with Mac Pros, 8GB modules cannot be mixed with other modules.

    I believe you can with the iMac and MBP though, as the Pro has to use registered memory for the 8GB or higher capacity chips, whereas the stuff for the iMac and MBP is just normal memory.

    OP, I'd try it and see how it works. In theory it should, but the higher density of the 8GB may not play too well with the low density 2GB, so if it does cause issues, I think Hellhammer had a good idea.

    He hasn’t really given enough information to tell what he can do. Also, I wouldn’t mix memory from different manufacturers. Anyway, I suggest he go here:

    http://www.crucial.com/mac/

    and check the Crucial Mac Memory Advisor™ tool to see what actually he can do.

    Is it really necessary to be mac memory or as long as the specs match (DDR3-1333) will work???

    Thanks for your replies...

    As long as it's the same spec, it should work. Occasionally, you'll find issues if you mix brands in the computer, but that's pretty rare.

    8gb + 2gb? i'd sell the 8gb stick and get 2x4gb sticks, the price difference doesnt justify the 2gb extra ram for me and running two different sticks of ram wont give you the best performance

    you guys think that I could do this?

    Transfer the 4 gb (2x2gb) of the mbp to the Imac (for a total of 8gb)

    use the 16gb (2x8gb) for the macbook pro...

    this ok? maybe the mbp and the imac OEM ram is different brand... could this cause a problem?

    that would work fine. The brands really won't matter as long as they are the same spec.

    It will work, I did something close to what you did when I got my MacBook Pro, I now have 12gb in my IMac and 8th in my MacBook Pro.

    I don't think so, actually I think you will have some trouble finding 8 GB SO-DIMM modules as they don't even exists on the market.

    There are some but they are expensive and not that easy to find. E.g. OWC sells them.

    I think you should sell the 16GB kit for a buttload of money and just keep 8GB in each computer. If the 16GB kit is $1500, I'm sure you can get $1200 easily. Is 10GB RAM over 8GB worth $1200? Probably not.
