Installing more RAM in Macbook Pro

I know this question has been asked a thousand times before, but I want to know if my specific MacBook Pro model, bought in October 2007 can take 4GB of RAM? I know that some of the older MacBook Pros can only take 3GB, but I'm unclear as to whether my MacBook fits into the older category or the new one.
Also, is it easy to install RAM if you are a complete technical no-hoper? And where should I buy my RAM from? My instinct would be to get it from Apple so that I know it's compatible and works well with the MacBook, but could I save significant money by looking elsewhere?
Thanks in advance for all your enlightening responses!

The simplest way to ID your machine is to run System Profiler (Apple menu > About this Mac,,, > More info...) and post the info under Hardware Overview EXCEPT for the machine serial number. Do not post the serial number in open forums. The "Machine Model" line is the most important to identifying your version.
The free Mactracker database uses the machine model code, making it easy to match a description to a particular variant's Machine Model code. My MBP is a 15" 2.2G C2D Late 2007, has a machine model code "MacBookPro3,1" and supports up to 4G RAM.
Mactracker can also help sort out those confusing Model numbers (with "A") form order numbers (With "MA"). Handy tool.

  • Installing 8GB ram on MacBook Pro (Mid 2010)

    Hi, I have bought 8GB(2*4GB) ram to install on my macbook pro, when I install both I get a black screen but when installing one or the other with one of the original ram they both work. What can I do to fix this problem??

    When you install RAM, reboot your computer with the "D" key held down (or the Option-D keys). These will load the Apple Hardware Tests.
    With these tests open, check the box for the extended memory test, and then start the test. This will have the system thoroughly test the RAM for errors.
    In your case, it appears you may have a bad set of RAM modules, but you can check them using the method above.
    When you have them paired with your original RAM, how much memory does the system report as being available when you select About This Mac in the Apple menu? If you are using Lion or Mountain Lion, then in this panel click "More Info" and then select the "Memory" section, and see what the system reports as being installed.
    Is this RAM test necessay with every upgrade of memory or just if you have problems after the upgrade
    Thanks

  • Adding more RAM to Macbook Pro

    I'm currently using a MacBook Pro 13" Mid 2012 model.
    At the moment, it has 4GB of RAM and I would like to upgrade it to 8GB of RAM. I will soon purchase DDR3 8GB of RAM and install it myself, however I have a little query, will 8GB of RAM drain my MacBook Pro battery life quicker? I wanted to have a stronger and faster computer.
    Thanks for your support,

    Welcome to the Apple Support Communities
    A faster computer consumes more energy than a slower computer. The battery life will be similar or the same when you install more memory, but of course, it will be less when you open more apps than the ones you had opened with 4 GB of memory, because 8 GB of memory allows you to open more heavy apps at the same time, consuming energy

  • Adding more RAM to Macbook Pro mid-2012

    Hi!
    I have a question about adding more RAM to my mid-2012 MacBook Pro (without Retina). I've been doing some video editing with Final Cut, and I'm using quite many apps on the daily basis. I have the standard configuration with 4GB of RAM (2x 2GB) but I guess I should upgrade it, shouldn't I?
    I had that idea in mind: buying extra 8GB RAM instead of one 2GB, so I'll end up with 10GB of RAM. If it won't be enough and I'll have some extra money, I will add another 8GB instead of 2GB, so I'll have 16GB.
    First question - is it worth it?
    Second question - can I add any RAMs supported by Macs? For example I'll leave one 2GB that I have already, and add 8GB made by, let's say, Kingston (I guess they are supported and they have good price in my country). Will this work fine? Does it make sense?

    Jerroslaw,
    since you’re running Mavericks, open up Activity Monitor while you’ve got your usual selection of apps running, select its Memory tab, and look at the Swap Used setting in the lower left. If it’s displaying “0 bytes” as the amount of swap used, then extra RAM won’t make a difference. Otherwise, to answer your first question, whether it’s worth it or not depends upon how frustrated you are running your usual selection of apps with 4 GB of RAM. It might be that the cost of replacement RAM modules outweighs your level of frustration — only you can make that determination of worth. I would recommend that if you do choose to purchase replacement RAM, that you get a pair of matching modules — either 2 × 4 GB = 8 GB, or 2 × 8 GB = 16 GB, to replace the pair that is currently installed.
    For your second question, you don’t have to use Apple-brand RAM, but you do have to use RAM with the same characteristics as your factory-installed RAM uses. Any worthwhile purveyor of RAM for Macs will let you easily locate modules that are compatible with your Mid 2012 MacBook Pro.

  • Installing more sdram on MacBook Pro 13" i5 (model early 2011)

    Hi . I'd like to know if I can install 2x8 Go of sdram on my MacBook Pro 13" i5 (april 2011) or if 2x4 Go is the maximum recognize by my model?  Thanks for your answer

    Although Apple only 'officially' suggests 8GB of RAM, your system will run and use 16GB of RAM just fine. Be sure that you buy or order from a reputable company (OWC and Crucial online are good choices) and stay away from any 'value' RAM.
    Also be certain to order the correct speed RAM for your computer - 204-pin PC-10600 (1333 MHz) DDR3 sticks. While some might be labeled to 'work' with 1333MHz and 1600MHz, for example, you want the correct speed to avoid any issues that might arise.
    Good luck,
    Clinton

  • Re: Adding more RAM to Macbook Pro mid-2012

    Hi,
    I am in the same situation as Jerroslaw, but in my case my "swap" says "0 bytes". what would be the best idea to increase my RAM?
    sorry for my lack of knowledge in this area..

    Ah! You're running CAD software! Yes, you could surely benefit with a RAM upgrade. To me, 8GB of RAM is the 'sweet spot' for RAM on any Mac - you can upgrade the RAM to either 8GB or 16GB (the maximum).
    Around here we tend to recommend Crucial and OWC RAM - it simply works with no problems with MacBook Pros where cheaper, 'value' RAM has trouble more likely than not. Visit the Crucial website and click on the System Scanner tab and download the small app. Unzip and run it and you'll be taken to the Crucial site with the exact upgrade options for your particular model. The exact specification for your machine are 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMMs. You can also check OWC - I just prefer Crucial because it's usually less expensive than OWC and it's what I run in my machine.
    Visit both sites and check out their offerings...

  • Problem installing 512mb RAM in Macbook Pro.

    Hi,
    I hope someone can help me, I have checked other posts and nobody seems to have the exact problem that I have after installing RAM.
    I installed a Crucial 512mb module in my Macbook Pro which already had a factory installed 512mb module in one slot.
    First time the Mac started up ok but it did not recognise that extra RAM had been installed. I reseated the crucial module and the Mac would not start, just a pulsing power light and a black screen.
    I installed one module at a time and the Mac booted correctly with both the Crucial Ram abd the RAM it shipped with.
    When I put in both Modules it will not boot, I switched the slots and made sure that modules were inserted correctly but no joy.
    Sorry for being so long winded!
    Macbook Pro   Mac OS X (10.4.6)  

    Thanks guys,
    It just seems odd that both modules are working correctly when they are installed on their own and there is no boot when they are installed together.
    As you stated it may be that the specs are different but I checked and all the info seems the same.
    I'll just go ahead and send it back to Crucial for a replacement.
    Thanks again.

  • Installed 8GB Ram into Macbook Pro, System Report says it only has 2GB RAM

    I decided to upgrade my 13.3 inch MacBook Pro from 4GB Ram to 8GB Ram.
    I purchased two Crucial 4GB Ram from two different dealers on Amazon and installed them myself.
    I turned my MacBook on and now it says that only one slot is being used and that it is a 2GB.
    I have a feeling that either one of the Ram slots has failed, however it still puzzles me that it says that 2GB of RAM is installed? Is there any way of refreshing the 'About This Mac' or is there anything to make the Mac recogise this problem?
    Thanks in advance

    open the mac back up and make sure both ram modules are seated properly.  It takes a little hard push to get them seated and you will hear a click/snap when they are seated.  To determine if a ram slot has failed, simply put back in the old ram, and if both slots are recognized, the problem is with the new ram.

  • Adding more RAM to MacBook Pro Help!

    Dear Apple Support Community,
    Ok so first of all don't tell me to go search for older discussions >:(
    Here are my system specs:
    MacBook Pro 15", Mid 2010
    Processor - 2.66 GHz Intel Core i7
    Memory    - 4GB 1067 MHz DDR3
    Graphics   - NVIDIA GeForce GT 330M 512 MB
    Software   - OS X 10.8.5 Mountain Lion
    I was going to buy some extra RAM and boost up my computer to about 16 GB total because my computer is running a bit sluggish lately when I'm running several apps at once (such as pages, keynote, chrome, steam, itunes...) but now that I've seen a few videos online and some reviews on amazon, I'm not completely sure which RAM is the one that will not screw up my computer. I saw a video on 'UnboxTherapy's Channel' where he said something about the timing of the RAM which is in the format like 9-9-9-24 or something, as well as some review saying something about the computer not working at all thanks to the RAM because the computers didn't match..
    Please help me find a 16GB RAM that will work on my computer (please try and keep the websites amazon if possible, I live in japan :/)
    and please explain to me what the RAM timings mean and how to figure out my timing...
    Thank you for reading

    Hi leroy,
    Thanks for the quick reply!
    I checked the Crucial site, and apparently my Macbook Pro can only upgrade until 8GB...
    Is there any way to upgrade to 16GB without any trouble?
    Also, if I upgrade to 8GB, will I see any difference? Some users say that you won't see much change between 4GB and 8GB of RAM... Is this true?
    Thanks!

  • More ram for Macbook pro gaming

    I was wondering i have a 6750m 512mb and 4gb of ram, if i upgrade to 8gb will it help improve anything? will it help boost frames it stuff like call of duty ghost? or anything else i have i7 , macbook pro late 2011

    Sorry, if I was paying attention I would have known that.  I am always of the belief that if you do any type of gaming, especialy console ports, at least 8GB of RAM is a good number and a graphics card with 1GB of dedicated ram.  Gaming asside, I consider 8GB to be a minimum these days.  Apple still pushes 4GB as a jumping off point and for most people doing day to day tasks on a Mac (web browsing, word processing, etc) 4GB of ram paired with an i5 processor is sufficient.  Most i7 processors are good enough for gaming, although quad core will make some difference.  So to answer your question, I would think you will see some frame rate improvements by doubling your ram but the graphics card may still hinder you a bit.

  • Installing more RAM into my Macbok Pro

    Hey guys,
    I'm looking to install more RAM (from 2 Gb to 4 Gb) into my MacBook Pro (15.4" Intel Core 2 Duo 2.2 Ghz) that I bought last September, and I'm strictly a software guy: I know little to nothing about hardware.
    What kind of RAM do I need to install?
    Also, I have the AppleCare protection plan. Will installing more RAM interfere with that at all? Do I need to have a Genius install it for me?
    I've installed a RAM, hard drives, and video cards before so I know I can do it myself if I'm allowed to by the plan.
    Thanks,
    - Keith

    Open your computer's User Guide. There's a whole chapter on upgrading memory in which the specifications are explained. If you don't have the manual you can download a PDF version from http://www.apple.com/support/manuals/.
    Installing RAM will not void the warranty unless you cause damage in the process.

  • 4GB RAM on MacBook Pro 15 ?

    I can put 4GB Ram on MacBook Pro 15 even if Activity Monitor and other similar applications will reveal that only 3 GB of SDRAM has been addressed for use by the computer ? you see apple doc : http://docs.info.apple.com/article.html?artnum=304662
    I would want put 4GB Ram on my new MBP.
    TY, Max Vigilante

    actually it's true. it's not the motherboard, it's the intel chipset. there was an interview with a tech spokesperson from apple about this on anandtech I believe.
    while you can physically put 4GB into the slots, the intel chipset will only be able to address slightly more than 3GB of it. apple made the decision to be reasonable about this and state that the max RAM for these machines is 3GB so that customers are not wasting their money on buying 4GB. other manufacturers are either not being so honest about it, or they haven't even bothered to pay any attention to the intel spec on the core 2 duo chipset. if your dell is reporting that it actually has the full 4GB (and it is indeed a core 2 duo machine) then it's just giving you a reading of what chips are installed, nothing more. any system profiling app that can really look into what amount of RAM is actually addressable will show that the full real amount is less than 3.7GB (or less than that I can't remember). the information is all there at intel if you want to go get it from the horse's mouth.
    there is absolutely nothing about OSX that limits it to less than 4GB. it makes no sense to assume that.. the OSX installed on MBPs is identical to the OSX on other machines like mac pros, which can support well and truly more than 4GB RAM as there is no chipset limitation in the xeons.
    anyway as I said, this info is all out there in the public domain, you can even email support at intel and ask them to explain exactly why the core 2 duo chipset (in any machine, mac or PC or otherwise) has this RAM limitation.

  • Will Windows 7 Pro run with 16GB of Ram in Macbook Pro Early 2011 13-inch?

    Will Windows 7 Pro run with 16GB of Ram in Macbook Pro Early 2011 13-inch?, Does the brand of the Ram matter ?
    I installed Crucial 16 gb and the Mac runs just fine but Windows won't start. It gets to the login screen then it turns white.

    I decided to make another try today after some reading and googling the internet.
    I started windows with my old 4GB memory and changed the bootconfiguration with msconfig. I typed manually in max memory tp 16384 MB and saved the settings. Then I turned it off and inserted the 16GB ram again. Then it started really but when looking at the properties of my computer it says 16 GB installed but I can only use 2,16GB. So I opened msconfig again and changed the settings once more and restarted. Now it says 16GB installed but I can use 14,2GB so I guess it is ok now for some strange reason. I suppose the lost 1,8GB is for the system ?? Do I dare to turn it off again :-) what will it say next time ?
    I am so happy and greatful for all your help, I really really appreciate it and I hope my solution will come to use for someone else with same problem.
    Thank You all :-)

    Im sorry for bombarding you with a bunch of questions.... but how much should a person be paying for ram. I noticed on the Apple site they have 4GB RAM for 100.00 but then you look else where and it 16.95 and up..... I am so confused.....

  • Debating whether or not to install more RAM????

    Hi I have a macbook late 2010. I currently have 2.4 GHz and 2 gb of ram. I'm debating whether or not I should buy and install more RAM. I was thinking I would either buy 2x4 or 2x8. Would this be a worth it upgrade. My only other option would be waiting another year, and buying a macbook pro then. Also is it even possibile to upgrade RAM on macbook? Any help would be appreciated, and please back up your answers.

    You're welcome. Based on your usage, your OSX, and the relative prices, I would go with 8 (2 x 4 GB) modules. This won't make your machine faster in a traditional sense...rather, it will prevent it from being slow...as it is now with extensive page outs. I would recommend purchasing the RAM from Crucial or OWC (both companies test  RAM extensively, are very reuptable, and provide 1 year warranty included).
    There is no late-2010 MBP 2.4 GHz model. Confirm RAM compatibility at crucial using their scanner tool:
    Scan your system to view your specific system configuration.
