Can I add 2x 2gb ddr3 to 16gb 27" iMac

I have a 2014 27" retina imac with 16gb ram. Can I safely add 2 x 2gb DDR3 from a 2010 Macbook pro  for a total of 20gb? Samsung 2GB 2Rx8 PC3 each.

No, add the RAM that Apple recommends!

  • Can I install one 2GB DDR3 and one 4GB DDR3?

    I have two 2GB DDR3 1333 Mhz sticks in my MacBook Pro. If I order a 4GB DDR3 stick, can I install my single 4GB and single 2GB stick and have 6GB of RAM or do I need to buy two 4GB DDR3 sticks so that each slot is equal?
    If I can do this, can I put the 2GB DDR3 1333 MHz stick replaced from the MacBook Pro into a MacBook which takes DDR3 1066 Mhz. This MacBook would have 3GB total? One 1GB DDR3 1066 Mhz and one 2GB DDR3 1333 Mhz?

    No, you need to put in the ram with the correct specifications.  If you dont, it could cause your mac to be unstable.

  • Can I add a second screen to my 09 iMac?

    can I add a second screen to my 09 iMac?

    Welcome to Apple Support Communities
    Of course. Just get a monitor and the Mini DisplayPort adapter you need to connect the Mac to the monitor. I recommend you to use HDMI if the monitor uses it. Also, you can connect it to a TV. See > http://support.apple.com/kb/HT4241

  • Can I add an internal hard drive to my iMac G4?

    My HD only has about 5GB left out of 80, and I know that's not good. If I can't add an internal, can I swap the hard drive for a new larger one myself?

    If you follow a good take-apart guide you can have the job done in a few hours. I replaced both drives on my old G4 w/ this guide:

    Just make sure you read the guide first and print it out so you don't miss anything as you begin surgery : )

  • Can't add a new event to an imaged iMac.

    I have an older iMac at work. It is on a network so all the macs are imaged. When trying to add a new event to iCal it just doesn't work. I try to drag in day but the it just diasappears. This iCal is synced with my computer at home. It works fine on the eMac which is not imaged at work but is also synced with my home computer. Any thoughts?

    William,
    It is a possibility that you are adding new events to your "On My Mac" calendars.
    "On My Mac" calendars will not sync with iCloud. After backing up the "On My Mac" calendars, and ensuring that all events are duplicated on your iCloud calendars you can delete any "On My Mac" calendars.
    For further troubleshooting advice read iCloud: Troubleshooting iCloud Calendar.

  • Can I install a 2gb Sata3 HDD in my IMac G5 20" ALS?

    I currently have a WD 2gb Sata2 HDD drive in my machine which is probably going to crash soon due to a node error I get when running disc verify in disk utility. The machine was running very slow recently which prompted the verify disc. I have 2gb of RAM running also.
    The local shops only seem to sell Sata3. Can I install this drive or do I have to source a Sata2?
    Many thanks
    Mdn

    Node issues can be fixed with booting from the 10.5 retail installer and running Disk Utility from the installer's Utilities menu to Repair Disk.  If that can't repair it, backup your data, and purchase Alsoft Disk Warrior.   If that can't repair it, yes replace the hard drive.   Faster SATA hard drives can be put in, if they either have a jumper than slows to 1.5 Gbps, or are designed to automatically downstep to that speed.  Check with the manufacturer if that's a possibility for the model you are looking for.

  • Can I put the 2Gb RAM (X2) from my MacBook Pro into my MacBook 5,1? The intel is different (2Ghz not 2.3) and the speed is 1067 not 1333. But they are both DDR3.

    Can I put the 2Gb RAM (X2) from my MacBook Pro into my MacBook? The intel is different (2Ghz not 2.3) and the speed is 2000 not 1333. But they are both DDR3.
    I have just upgraded the Pro to 16Gb and the MacBook is SO slow. Just wondering if I could use the old RAM.

    Full specification of MB5.1 RAM;
    204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM, non-ECC (non parity), unbuffered.
    MBP8.1, 8.2 or 8.3;
    204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM, non-ECC (non parity), unbuffered.
    PC3 is the same as DDR3. the number is peak transfer rate (approximated).
    Further reading suggests your swap may work, but it's not guaranteed. If you get 3 beeps on start up (or the sleep light flashing in bursts of 3), first check it's correctly seated, but be prepared to swap them back.
    If you encounter any instability or kernel panics, change them back.

  • HT1651 Can i use Samsung 2GB PC-8500 DDR3 1066MHz SO-DIMM 204 Pin 2.0GB Memory Upgrade Modules M471B5673FH0-CF8 with my mac bool mid 2010?

    Can i use Samsung 2GB PC-8500 DDR3 1066MHz SO-DIMM 204 Pin 2.0GB Memory Upgrade Modules M471B5673FH0-CF8 with my mac bool mid 2010?

    you are out of luck, I think.
    Not using the exact spec for memory wil cause trouble.
    When you have the original in (1066MHz) and add another with higher speed (1333) there is a (small) chance that the higher speed one is "clocked down" and will work, but expect kernel panics often. Most of the time it will not work.
    If there is no standard spec ram in at all, the mac will not start.
    Luckily ram is cheap nowadays. Send it back.
    The best way to buy is researching the Manufacturers' site and use the configurator, then go shopping, if you want.
    Use only respected brands: Crucial, OWC, personally have not so good experience with some other brands. And remember "pennywise is poundfoulish".
    I think Amazon will take it back and refund. Very unlikely that the memory is harmed. Ask them to take it back.

  • How much ram can I add to my late 2008 MacBook Pro? I run Mavericks and just got a new inexpensive hard drive. RAM is not very expensive so Thought I would bump it up from the current 2MB of 1067 Mhz DDr3

  • Can I add 2gb RAM to MacBook Pro 2.53?

    I may be buying MacBook Pro 2.53ghz that already comes with 4GB Ram.
    But in selling my MacBook 2.4ghz, the buyer doesn't need the extra 2GB that I fitted in there.
    Question is, can I use the 2gb from my old Macbook to fit into MBP 2.53ghz?
    Forgive my ignorance on this issue. I have no idea how the RAM slots work!
    Message was edited by: RUnited

    No.
    For two reasons. First, unless your old machine is one of the brand new late 2008 models, it does not use the DDR3 1067MHz memory. So the memory in that machine is different and won't work.
    Second, even if your old machine was one of the brand new computers... the 2.53GHz machine already has 4GB installed. It gets there by putting a 2GB memory module in each of the 2 slots inside the computer. Meaning, there are no slots left.
    Some sites on the internet are reporting that it is possible to boost the memory of the new MacBook Pro to 6GB, but the way people are getting there is to remove one of the 2GB modules and then replace it with a 4GB module. Because of a limitation in the design of the system/operating system, you can not currently pull out both the 2GB modules and replace them with 4's to get you to a max of 8GB.
    Hope that helps!

  • Can I add datafile bigger then 2GB

    Hi all,
    Can I add datafile bigger then 2GB (on the raw device) to the tablespace ?
    I get err:

    ORA-27042 : not enought space on raw partition to fullfill request

    thanks

    If you want to use raw devices with linux you have to use the utility 'raw' to map the device. You could also use the Logical Volume Manager (or both)

  • Can I add 16GB memory to my U31 Lenovo laptop?

    Welcome to the Lenovo Community !
    According to your model's Hardware Maintenance Manual specifications, 8GBs is the maximum memory that can be installed.   Here is a link to that manual for your reference......

    I followed your instructions and installed Developer Suite 10G on Windows Vista Home Premium edition. I have Oracle 11G DB running on the same machine.
    Two points, Steve:
    1. When I tried to set the maximum virtual memory to 6110 an error message displayed from Windows and told me that I can't set the maximum virtual memory to more than 4096. I set it to 4090 and it worked and I got nothing wrong during the installation process.
    2. After installing JInitiator and disabling Java on Firefox I called the http://127.0.0.1:8889/forms/frmservlet page and everything seemed to be OK because the Oracle Forms Services logo appeared and then a successful installation message appeared , but as I clicked (ok) to continue a gray screen appeared inside the browser (like the one displayed when you try to run a Java applet inside a browser) and then I wait to death till something appears but sadly nothing. I just get a blank gray screen inside my Firefox browser.
    Do you have any idea what to do to solve the problem?
