Imac 13,2 with 3 RAM chips instead of 4 RAM Chips. Is there any hard data supporting the fact that the iMac will not run optimally with only 3 chips versus 4?

I have a imac 13,2 with 3 of the 4 memory(RAM) slots filled. Two with 4gb chips and one with an 8gb chip. Is there any reports or statistics to support using matching pairs(4 chips) of ram versus running 3 chips? Is the machine running optimally w/3 chips? Or does it not matter with these newer imacs as each RAM slot is fully iundependent of each other therefore getting the most out of each chip no matter if 3 slots are filled or 4 slots are filled?
Thanks for any reponses.

There were some models which would not boot at all if a certain slot was not occuplied:

  • Any news from Apple as to when they will fix the issue that iphone 4s will not sync music with itunes?

    I have tried all of the suggestions in the support communities. Itunes shows that my phone and my library are synced, however none of the changes I made to playlists show up on my phone
    Is there any word from Apple as to when this will be addressed?

    So this isn't just me? I'm getting on a flight in 12 hours and I've been trying to copy a book on tape over... I've got my cable but nothing will sync. It just keeps insisting I put everything on the cloud... However I can't bloody download audiobooks from the iCloud when I'm on an AIR PLANE. Would be nice to fix this up...

    The system doesn’t recognize or capitalize the word (I) or the first word of every sentence. Another really annoying thing about the integrated mail on your Mac computers is the fact that the system learns the word as you type it more and more instead of highlighting it as incorrectly is this is a word that’s being misspelled. Can Apple fix this bug to make it user friendly as if you were using Office or a Word Document?

    You hit the target CT.
    It’s only fair that if Apple is going to integrate Mail into Mac PCs, it would be nice if the system does it for you like Office or perhaps Outlook. I just don’t to use Outlook although I have it installed and ready to use, but instead use Mail which comes with Mac OS already.
    I hope to make some sense here.

    My deepest apologies. My brother sent this Mac Mini out for repair to a company called D T T systems. The problem was a broken plastic ram holder. When that was done during a failed memory upgrade. We paid 325.00 the or something for refurbished Motherboard. However, upon recieving it we found through running the serial number through apple it is a Yonah processor 1.8ghz board. When I have a 2.0ghz core duo forced on this board somehow. I sent it back two months later I was assured it was the proper board and simply it was not. I now know from Apple's Tech support. The same board. What a joke. I am truly sorry guys for the trouble. Somehow it registers those specs with processors and memory. Yet the serial is the completely wrong board. Worst company ever. You guys are the best.

  • Mozella 3.6 will not run well with Adobe Flash Player 10.1-- IE8 and Adobe Fpash Player 10.1 does work

    I use filehippo.com to automatically update my applications. So I have Mozella 3.6 and then recently downladed and installed Adobe Flash player 10.1 or the latest version.
    I then proceed to http://www.africam.com/wildlife/lc_player_chat.php?sh=nk-1
    and found that the picture will not show- I get a running circle and then a brown square instead of the pic.
    Now using IE8 and the same version of Adobe Flash Player I get the picture.
    This worked in Mozella before the last update of Adobe.
    Can you give me any direction to fix this?

    Hi, not sure what that is about. Did you use the Adobe Uninstaller first and follow the instructions?
    I would download the Uninstaller and SAVE it to your Desktop:
    http://kb2.adobe.com/cps/141/tn_14157.html
    Then I would download and SAVE the Installer to your Desktop:
    http://www.adobe.com/products/flashplayer/fp_distribution3.html Use the EXE Installer for Windows/IE
    Once you have that done, then Close all browsers, disable any messenger services in the system tray(area near the clock)
    Run the Uninstaller and when it is finished, Reboot(restart) your computer.
    Then run the Installer and reboot when it is finished.
    Then test here and you should see the Flash logo animation and the version of Flash Player that is Installed.

    Which is why they should just press "enter" when in doubt.
    I know this isn't your full time job, but perhaps you might want to write another alternate script
    Apple says it is going to write one.
    Another thing. When it was busy scanning Applications -- I know it says "this may take some time," I gave up and hit skip after giving it a very long time to finish.
    Thanks. Don't mean to be ungratefu for your good work on this.
    There is no way to tell how long that will take. If I had to edit that script, I would just remove that part. I was following advice that was not accurate in the ensuing blog frenzy. That was costly. I didn't have much time, so should I have gone ahead and scan system areas or done a better job with LaunchAgents? I made the wrong choice.
    I always welcome suggestions. Unfortunately, comments on User Tips seem to be locked down pretty tight.
    It is a moot point now that Apple is going to write a script. When that happens, I will take down that script. Until then, I'm just reminding people to press "enter" when in doubt.

  • Is the fact that the new MBP with Retina display, has choppy scrolling in safari, a reason not to buy it? Can it be fixed through software?

    I am debating buying a new MBP with Retina or a Macbook Air. I am looking for more info on wat people have been saying about lag in safari. Thanks!

    Hey fredryan..did you end up getting the rMBP?  I too am a little concerned about the screen performance while I wait for mine to ship.  If you have gotten yours do you mind commenting on how Mountain Lion affected it?  Is the lag still a big issue?  Thanks!

  • Ihave had to buy 2 chargers due to the fact that the square adapter was left behind,,, the charger is the same color as the face plate and was not noticed. Can you buy just the square adapter instead of the whole unit?

    I have had to buy 2 chargers due to the fact that the square part of the adapter separated from the cord and was not noticed and left behind in the hotel (same color of the faceplate)
    Can you purchase this part separate from the complete unit.?
    This is a very costly design issue. i'm sure many have done the same.

    Apple does not sell the power adapter separately from the cable. If it was the power adapter that was taken - I'm not certain from the way you phrased things - you'll have to buy both:

    I have never been able to use the Macmail feature.  Running OSX 10.4.11, and the problems appear to be related to the fact that when I originally registered my computer with apple, I used an old e-mail address which is now defunct.  Have since upgraded the e-mail address in account manger, but it still locks me out and rejects my user name and password when I try to log in.  It seems it established an account for me automatically when I first fired the beast up, but now the Macmail program is uncooperative with me.  Any assistance would be much appreciated, Thanks

    Hi rbcjoker76, and a warm welcome to the forums!
    Sounds like some needed System Fonts wre replaced by bad ones. Y also have Font Book in Applications for validating fonts & checking for duplicates.
    Required Fonts from 10.3, much the same in 10.4...

    then intall the Fonts what you need from your Install Disk.
    Or do a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...

  • Imac 27" Intel Core 7 CPU. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware scan and all is fine. Did clean wipe from Mavrick back

    Imac 27" Intel Core7  CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.

    I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
    So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly...
