How much RAM can my computer hold?

I have a Macbook Pro 2GHz, I believe one of the first models that came out. I have 1GB RAM, and while looking to buy a 2GB upgrade, I couldn't figure my computer's max memory. Can all of the Macbook Pros use 3GB of memory, or do the original models only use a max of 2GB?

On the first Core Duo models 2GB is maximum RAM

  • How much Ram can my MacBook hold?

    Hi, I'm looking at upgrading my MacBook Ram from 2GB to 4GB. I've had a look around various websites, forums etc. to find out how much Ram my Mac can hold but it seems to have given me conflicting advice. The Mac is from late 2006. It has Intel Core 2 Duo, 2GHz, 250GB and currently has 2GB Ram. If anyone could give me an answer I would really appreciate it :-)
    Thanks.

    I sure do. Try OWC orDataMem

  • HELP: How much RAM can my G4 hold?

    Hey, quick thanks up front to anyone who answers this.
    I've got an iBook G4 that I bought in 2004. It's a 1Ghz G4 with a 60gig hard drive. When I bought it from MacMall, I got a free RAM upgrade, and as such up until about a month ago, it had 640MB of RAM. Then without warning the upgrade RAM died. I was left running with the 128MB that were built in. You should try running Dashboard on 128Megs... It's ****. I have since taken the bad RAM out, and am looking into replacing it/upgrading so I have 1GB of RAM. Now here's the thing: When I went to the Apple specs page, it said that my computer could only have a maximum of 640Megs of RAM. But when I look at the slot, it seems to match the same size as for the 1GB cards. How much can I really hold? I would like to be able to go to 1GB.
    Thanks for any help.

    iBook G4, 1Ghz, 128MB Built in, 60GB Hard Drive, Combo Drive, Tiger   Mac OS X (10.4.7)   Had Ram Upgrade Previously

    Your computer will accept a 1GB module. This is not stated on Apple's specifications page because 1GB modules were not available when that iBook first came out, and the specifications were not updated afterwards.

  • How much RAM can my computer handle?

    I have a iMac that was manufactured mid 2011 21.5 inch display.  The specs say it can only handle 16GB of RAM but here's the response I got from the RAM manufacturer:
    "Whist your official manufacturer specification recommends 16GB maximum capacity, we can confirm that your iMac can support up to 32GB because this has been rigorously tested in this system and is guaranteed compatible.
    But I can set up a refund for you, if you would still like to purchase other memory modules."
    Here is my response:
    "Can you guarantee in writing that 32GB of RAM will work for my machine and not hurt it? If it breaks because of too much RAM do you replace the computer?"
    Please advise 16GB or 32GB.  By the way, I gave the manufacturer the serial number of my iMac so they shouldn't gotten this wrong.

    Get your hands on the ever-useful app, Mactracker. It lists all the specs for one's Mac including the latest capacity for RAM.
    You can get it here or at the Mac App store (and iOS store)

  • How much RAM can my computer support?

    This computer has four memory slots but I don't want to buy memory that I don't need. Also I am currently running SDRAM-PC133-333, but most sites say that this model computer should run PC120, or 100, or something like that..........will I be ok running the PC133-333? Another question: my internal hard drive only has 20GB and I want to be able to run Logic Pro 8 smoothly what sort of hard drive upgrade should I go with?

    smida7, welcome to Apple Discussions.
    Since you mentioned PC100 RAM, you probably have an older Mac. Look at these G4 specs & tell us which one you have. http://www.everymac.com/systems/apple/powermac_g4/index-powermac-g4.html The older Macs came with PC100 (100MHz) RAM, but you can install PC133 RAM because it's backward compatible. That is, PC133 RAM will operate at PC100 speed. Your Mac can probably use up to 2GB of RAM (4 each 512MB modules) while booted in OS X, however, only 1.5GB may be recognized while booting MacOS 9.
    On your hard drive question, look at these links.

  • How much ram can my iMac take?

    Hi all, just bought a iMac a few days ago and I'm just wondering how much ram can it take as I want to upgrade it. It didnt come with a manual, so I don't know.
    Here's the spec so far
    Early 2008 20"
    Processor  2.4 GHz Intel Core 2 Duo
    Memory  2 GB 667 MHz DDR2 SDRAM
    Graphics  ATI Radeon HD 2400 XT 128 MB
    Software  OS X 10.8.2 (12C60)
    Thanks for any help in advance

    There are two answers: the official Apple answer and the "you're on your own" answer.
    1 - For the official iMac max RAM, see iMac Memory specifications and upgrades
    2 - For the "your're on your own" answer, everymac.com has a list of the Actual Maximum RAM you can put in every model Mac.  In many cases this is more than the official maximum RAM.
    After deciding how much RAM you want to put in your iMac, I suggest going to Crucial.com and use the memory advisor or system scanner to see what RAM modules are compatible with your iMac.

  • How much ram can I put  In a 12" 867MHZ?

    Hi,
    I've just picked up a 12" 867mhz Powerbook for a very reasonable price! My question is how much ram can i put in it? It currently has 640mb. Also if i can put some more in it will it run Leopard?

    Bear in mind you can customise the install of Leopard to exclude some languages and particularly exclude printer drivers that aren't relevant to you, this will substantially lower the total required space. 12" Powerbooks are rather fiddly to work on - here's a really thorough guide on Hard drive replacement etc. for your Powerbook:

    physically 8 x 16GB, addressable in 10.8.3 is 96GB

    Hello miss_papaya
    That model supports 2 4GB modules for a total of 8GB, only problem is that 4GB modules are currently at a premium price. Have a look at the spec's in the following article or in the User's Guide that came with your iMac.
    http://www.apple.com/imac/specs.html
    Also have a look at Crucial and OWC memory below:

    I want to upgrade my RAM, as the computer is showing a bit of age at 3 years old now.  I looked at this support page:
    http://support.apple.com/kb/HT1270#link8
    And judged the installation to be easy enough for me to do, but I'm confused as to how much RAM I can buy.  The conflict I see is that "Additional notes" says I can use up to 8GB of RAM, but the table says only 4GB.  What's throwing me off is basic math -- is that 4GB only referring to my slots (thus 4+4=8) or is it saying that anything over 4GB will not be recognized by my computer?
    I spoke with someone at Apple, but he seemed a bit confused by my question, and eventually gave me a "yes" that was timid enough that I felt the need to post here.  So, I'd appreciate the support!  Thanks a lot, everyone.  I'm just looking to not spend more than I need (in terms of buying excess RAM), and make sure I don't ruin my Mac in the process.

    The MacBook Pro 4,1 can acces a maximum RAM of 6GB
    However RAM comes in 4GB modules and you have two slots, so you install 8GB (two 4GB modules) and can only access 6GB of it according to MacTracker.
    Use the free Crucial.com site to make sure your getting the extact specified RAM specs, you can buy it anywhere if you like.
