How To Install 2*4GB RAM=8GB Ram 1333mhz on a 13inch MacBook Pro 2.26ghz

Hi There,
I would like to install 2*4G which is 8GB RAM with 1333mhz DDR3 on a 13inch MacBook Pro mid 2009 2.26 GHZ and the bus speed is 1067mhz, now how would I install this type of RAM or must I rather spend more money for a 1067mhz DDR3 2*4GB=8GB RAM.
PLZ Help.

Welcome to the Apple Support Communities
You have to spend money and buy 1066 MHz for your Mid 2009 MacBook Pro. If you try to use 1333 MHz RAM with your Mac, it may not boot and start beeping, showing that you have incompatible RAM.
You can buy memory for your MacBook Pro in OWC or Crucial > http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3

  • HT3777 How to install Boot Camp on 32bit Windows 8 on a 2011 MacBook Pro?

    I used Boot Camp to install Windows 8 Consumer Preview as the 2nd OS on my 2011 MacBook Pro. However after the installation I cannot install the additional Boot Camp just the drivers for webcam/wifi/ethernet/cardreader/display/chipset etc.
    But I would like to be able to use the function keys to adjust the brightness and volume like on a normal laptop without having to go through settings.
    Anyone know how?

    You need to install the Boot Camp Windows Support Software, but I have no idea which version of OSX you have so, if 10.6.x the software is on the OSX install disk, likewise for 10.5.x, if you are running 10.7.x (lion) it is a download from the Boot Camp Assistant.

  • How to install OS X and built-in applications on SSD on MacBook Pro 2012?

    I'm considering replacing the hard drive on a newly purchased MBP 13" 2012 with a SSD myself.  How do I install the original OS X and built-in applications on the SSD?  Do SSDs have limited number of writes?  If so, what is its theoretical life?   Does this void the Apple warranty?  If so, then I'd wait until the warranty expires.

    The problem is probably not the boot key, although that would be an option key.
    Secondly, a1186 may refer to Mac Pro 1,x ; 2,x, or 3,x.    1,x and 2,x are only able to boot up to Mac OS X 10.7.5 natively.    That is the Machine ID in the System Profiler.    http://www.jabbawok.net/?p=47 explains how to install a newer OS than 10.7.5.
    command-R only works with newer Macs than July 20, 2011 and older ones with the right firmware.   That's documented here:
    Computers that can be upgraded to use OS X Internet Recovery - Apple Support
    As you'll see in that link, the Mac Pro is not among them.
    Now you can install 10.6.3 retail on the Mac Pro, and 10.6.6 combo or 10.6.8 combo to upgrade to 10.7.5.     But you can't install 10.7 or later otherwise.
    10.6.8 combo is needed for 10.8 or later if the Mac is officially supported on 10.8 or later.
    Backup your data before installing anything.  And if you have older software, be sure to read this tip before proceeding, as a lot of software is only compatible with 10.6.8 and earlier:
    Upgrading to 10.7 and above, don't forget Rosetta!

  • How do I test RAM on a mid 2010 MacBook Pro

    Yesterday I upgraded my RAM from 4gb to 8gb.
    I want to do a hardware test to check all is working fine behind the scenes. I trawled yesterday for answers, have tried to perform the AHT with Option D etc but think due the age of my Mac this capability isn't valid on my Macbook pro?
    Can someone recommend the best way to test my RAM. I am using MacBook Pro - Mid 2010 cycle, 2.4 GHz Intel Core i5, OS X 10.9.3
    Would appreciate some advice.

    Download from Kelley Computing REMBER.  Run it overnight in order to execute sufficient loops.

  • 1333Mhz Ram showing up as 1600Mhz MacBook Pro 15 Late 2011

    Hi All,
    I have a weird problem here.
    I have a late 2011 15inch Macbook Pro. I recently upgraded it to 1333MHZ 8GB (4X2) transcend RAM - (Transcend RAM Model JM1333KSH-4G)
    Now the problem is that the transcend RAM specifications show that these are 4GB 1333MHZ RAM but on installing in my Macbook Pro, it shows the frequency as 1600MHZ under "About Mac" menu. I have tried this with 4 different transcend RAMs to make sure that RAMs are ok. All the 4 RAMs show 1600 MHZ in my mac. Can this be a problem with my laptop?
    Apple support team suggested to reinstall the OS so that it updates with the correct information. I reinstalled the OS (not clean install, just reinstall), but still it shows 1600MHZ.
    Can somebody explain the problem to me? Is this normal ?
    Thanks in advance.
    Vikram

    Hi Dominic,
    Thanks for the reply.I really appreciate.
    This is one of the safest solution.I can return it but in our region Transcend is a trusted brand with acceptable service and repair. So, there are not too many reasons from moving away from the brand !!
    Further, i have tried with 4 different RAMs.All resulted in the same problem. My guess is that either the RAM model or my laptop is having problem.
    It would be great if some of our friends who have done a similar RAM upgrade with Late 2011 Macbook pro can share their experiences.
    Hopefully, i am not the only one to fall for transcend
    Thanks,
    Vikram

  • How will i increase the shared memory of the graphic card of macbook pro 13-inch, early 2011 from 4gb memory?

    how will i increase the shared memory of the graphic card of macbook pro 13-inch, early 2011 from 4gb memory?

    The current version of Mavericks is 10.9.4. To update yours download and install OS X Mavericks 10.9.4 Update (Combo).
    You can upgrade RAM to the maximum your model will support. That would be:
    Maximum Memory
    16 GB (Actual) 8 GB (Apple)
    Memory Slots
    2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
    About OS X Memory Management and Usage
    Using Activity Monitor to read System Memory & determine how much RAM is used
    OS X Mavericks- About Activity Monitor
    Adding RAM only makes it possible to run more programs concurrently.  It doesn't speed up the computer nor make games run faster.  What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent.  It will improve the performance of applications that run mostly in RAM or when loading programs.

  • Purchase RAM for Macbook Pro  2.26GHz Intel Core 2 Duo Mid-2009

    Hello,
    I need to upgrade the current memory(2 GB) of my Macbook pro (2.26GHz Intel Core 2 Duo Mid-2009) model..Can someone please suggest where I could purchase and what is the maximum and optimal that I could buy.
    Also I reside in India, so should I get it online or from the apple store which is like 100 km (nearest) from my place .
    Thanks
    Shubham

    You can buy them oniine if you wish to do so.  Buying it from Apple is a good idea but would cost more, and since it's 100km away, after your gas = more money.
    The maximum you can install is 8GB.  Your RAM specs are 1333MHz - DDR3 - 204PIN SODIMM.
    Check here for current prices online and compare to the price Apple sells them in your area.
    If you're not in a big rush - then buying online is a good idea.
    Good luck

    I've installed windows 7 with the help of bootcamp on my macbook pro 2011.
    Please help me how to install mac drivers for windows7 64 bit???

    You either download drivers from within Boot Camp Assistant and save to USB FAT disk, or you insert and use 10.6.x OS X DVD when in Windows and install and run the SETUP from there.

    Step 4: Install the Boot Camp Drivers for Windows
    After installing Windows, install Mac-specific drivers and other software for Windows using your Mac OS X installation disc.  The Mac OS X disc installs drivers to support Mac components, including AirPort,built-in iSight camera, the Apple Remote, the trackpad on a portable Mac, and thefunction keys on an Apple keyboard. 
    The Mac OS X disc also installs the Boot Camp control panel for Windows and theApple Boot Camp system tray item.
    To install the Boot Camp drivers:
    1 Eject the Windows installation disc.
    2 Insert the Mac OS X disc.  If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
    3 Follow the onscreen instructions.
    If a message appears that says the software you’re installing has not passed Windows  Logo testing, click Continue Anyway.
    Windows that appear only briefly during the installation don’t require your input.
    If nothing appears to be happening, there may be a hidden window that you mustrespond to. Check the taskbar and look behind open windows.
    Important: Do not click the Cancel button in any of the installer dialogs.
    4 After your computer restarts, follow the instructions in the Found New Hardware  Wizard to update your software drivers (Windows XP only).
    5 Follow the instructions for any other wizards that appear.
    6 Check for updated Boot Camp drivers by using Apple Software Update or going to www.apple.com/support/bootcamp.
      If You Have Problems Installing the Device Drivers 
    If it appears that the Boot Camp drivers weren’t successfully installed, try repairing them.
    To repair Boot Camp drivers:
    1 Start up your computer in Windows.
    2 Insert your Mac OS X installation disc.
    3 If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
    4 Click Repair and follow the onscreen instructions.
    If a message appears that says the software you’re installing has not passed Windows  Logo testing, click Continue Anyway. 
    If you need to reinstall specific drivers, you can install one driver at a time. For example,if your built-in iSight camera isn’t working, you can reinstall just the iSight driver.
    Individual drivers are in the Drivers folder on the Mac OS X installation disc.

  • How to install Windows XP in parallel with Mac OS on a Macbook?

    Can anyone tell me how to install Windows XP in parallel with Mac OS on a Macbook?
    If I divide the hard drive into 2 patritions and install Win XP & Mac OS on each patrition, is it ok?

    I don't think he meant "Parallels", I think he just meant "parallel", with a little 'p'.
    There are three options for running Windows software on an Intel-based Mac:
    Virtualization: you can install software such as Parallels or VMWare (along with a licensed copy of Windows) which will emulate the environment necessary to run Windows software. Performance is significantly degraded, but you can work with both Windows and Mac software simultaneously.
    Dual boot: You can use Apple's Bootcamp to partition your drive and create a CD of Windows drivers for your devices, so that you can then install Windows on one partition of your drive. Your Windows software will run just as it does on any other Windows PC, but you have to reboot to switch between Windows and OS X.
    Crossover: Crossover is a product that allows you to run Windows programs in OS X without installing Windows. Not all Windows software will work with Crossover though.

  • My Apple ID changed back to an old ID when I installed last update on my iPhone 5s.  How can I change it back to match what is on my MacBook Pro and iPad?

    My Apple ID changed back to an old ID when I installed last update on my iPhone 5s.  How can I change it back to match what is on my MacBook Pro and iPad?

    Hi GlendaGirl,
    Thanks for visiting Apple Support Communities.
    It sounds like you're unexpectedly seeing the incorrect Apple ID on your iPhone 5s. You can use these steps to sign out of iCloud on your iPhone 5s and sign in with the right Apple ID:
    iOS 6 and later: Go to Settings > iCloud.
    If you're still signed in with your previous Apple ID:
    Scroll down and tap Delete Account [Sign Out in iOS 8.] Depending on what iCloud options are turned on, you'll be asked to confirm that you want to delete data from your device. To confirm, tap Delete. (If you're using iOS 7 and have Find My iPhone turned on, you'll be asked to enter the password for your previous Apple ID. Enter the password, then tap Turn Off.) The data will be deleted from your device, but not from iCloud.
    Enter your current Apple ID to sign in. The data from your iCloud account will download again to your device.
