    I plan to upgrade my macbook pro's ram, but I sort of am confused with what I have read online regarding what type of ram would best suit my specifications, how much can I increase the memory (how much can each slot carry)? etc

    I have a pre-unibody core 2 duo MBP 15", early 2008 (or late 2007 'not quite sure'), 2.5 GHz, FSB 800 MHz, 2 GB RAM

    what type(company) of RAMs are recommended, and how much more can I add?

    Thank You

    Your computer can take up to 4GB, 2GB in each of the two slots.
    It takes DDR3 PC3-8500, DDR3. Crucial, GSkill, Corsair are all good brands.
    Go to www.crucial.com and let it scan your system to be sure.

    you need 200 pin PC2-5300 DDR2 667 MHz ram... 2 x 2GB will work fine, but between your post and this link, your MBP should be able to take 6GB in the form of a 4gig and 2 gig stick.

    If it's the early 2008 4,1 MacBook Pro then it can take a Max of 6GB of RAM, even though Apple says it's 4GB.

    That's why I am suggesting doing the scan. The OP was not sure of the year and if it's a late 2008, Crucial says to use the RAM above. Perhaps the OP could look at the Model Identifier in the System Profiler and see if it is a 4,1, but that would make it 2.4Ghz, and if that is the case, one 4GB and one 2GB chip for a total of 6GB is the max (PC2-5300 DDR2)

    I checked system profiler and it's the 4,1 model. So I can do up to 6gb, cool! Should I go with Crucial, I've heard they are very good. And what actually makes one brand better than the other? Can two slots, for example, carry different brands?

    Thank you all

    Normally you would go with samsung or hynix ram for maximal compatibility, since these are used by apple. But any other of the named manufacturers will likely suffice.

    Here you find apple's instructions to make the change.

    "For best performance, fill both memory slots and install an identical memory module in each slot."
    So you should be able to install two different brands of ram.
