Mixing ram SIZES in Late 2013 i7 27" iMac

Just assume all ram sticks are the same specs.......
Can I mix ram SIZES in Late 2013 i7 27" iMac? I.E. : two - 4 GB and two - 8 GB?

You should try to balance RAM out as equally as possible between available slots.
For example, 2 4 4 4,  2 2 4 4,  2 2 2 4,  but not 2,4,8,0.   And where you only have two slots, 2 2,  2 4,  4 4,  and so on.

    You must use the Windows formatter to format your Windows partition NTFS. Please be sure you select the Windows partition otherwise you might end up formatting your OS X partition NTFS.

  • Mixing ram sizes

    Hello,
    I recently purchased a macbook pro i7 late 2011 edition. It currently has 4GB of ram(2x2GB). I am wondering if it is possible to purchase a single 8GB(1x8GB) stick of ram and trade out one of the old 2GB sticks in order to have a total of 10GB of ram. I am aware 16GB ram kits are available but they are currently too expensive for me so atleast this way I could purchase one stick of 8GB for now and then purchase another down the road.
    8GB of ram is not enough for me. So my question is if whether or not I can mix ram sticks. Please only respond if you know for a fact and why, I don't appreciate people making guesses.
    Thank you!

    No one can answer your question with certainty. Some people mix different RAM brands and sizes and even speeds, and don't have any trouble. Others try it and have nothing BUT trouble. No two Macs or Mac users are alike in all respects, so there's no knowing why it works for one and not for another. It's a safer bet to use exactly matched pairs, but you might be fine with whatever mismatched modules you choose. If you buy from a vendor who offers a lifetime warranty, you'll probably be able to return anything that doesn't work out for you. But you can't eliminate the chance of getting bad RAM no matter what you buy, and you can't be sure that even a good module will behave perfectly when paired with a module that you have now.
    There are some vendors who offer RAM modules in pairs from one manufacturer but in unmatched sizes, and warrant them to work properly together. You may want to consider buying a 4GB and an 8GB module from such a vendor, adding a small amount in cost but giving you 12GB and a solid warranty. Here's one dependable source:
    http://eshop.macsales.com/shop/memory/Apple_MacBook_MacBook_Pro/Upgrade/DDR3_133 3MHz_SDRAM
    Note that the extra 4GB only costs $15 more than a single 8GB module.

  • Mixing RAM sizes and issues

    I'm having an issue with my late 2012 iMac 27 inch. It came with 8GB stock RAM installed on the 1st and 3rd slots (lookin from bottom to top). The 2nd and 4th were empty. I bought a Crucial 16GB RAM (http://www.amazon.com/Crucial-PC3-12800-204-Pin-Modules-CT2C8G3S160BM/dp/B008LTB JFW/ref=sr_1_1?ie=UTF8&qid=1365482251&sr=8-1). I installed the new ones in 2nd and 4th slots. Much to my surprise, when I switched on the machine and checked "About my Mac", it only showed 16B 1600Mhz RAM instead of 24GB RAM and after a few seconds, the system hung. I restarted the machine and I heard several beep sounds and the system never turned on. I checked th slots and all were seated OK. On switching again, I heard the same beeps. I switched off the machine completely, waited for a few seconds and tried again and then all was normal. The system was showing 24GB RAM and I was able to use my system for couple of hours and all was OK.
    I have couple of questions:
    1. What's going on here?. Is it a bad RAM that I need to worry about?. I still have ample time to order a new set of RAM and return the ones I have now.
    2. Why the system acted up and now it is OK even though I didn't change anything?
    3. Is the seating correct?. What is the best order to get maximum performance?. I intend to remove a 4GB RAM and keep it at 20GB RAM. If that's the case, what should be the order of arrangement?
    4. Is there any cause of concern that my system is acting up?. I'm well within my 14 day return period and I can go for a exchange if you guys feel that way.
    Please advise.
    Thanks.

    Sounds like maybe the modules are not firmly seated in the slots.
    Try re-seating them, only this time push real hard on each module with both thumbs to ensure that than are firmly seated in the slots.

  • Mixing Ram Sizes in Triple-Channel

    I would like to install 10 GB of RAM in the following configuration on my 2009 Mac Pro (flashed to 5,1):
    Slot 1:  4GB
    Slot 2:  4GB
    Slot 3:  2GB
    All 3 dimms are Apple OEM Hynix brand.  All are 1333MHz.
    Will this arrangement take advantage of the triple-channel capability?  I'd test myself, but don't yet have all the RAM in my hands.

    Triple channel means that the processor can read and write 3 DIMMs at the same time. So if you don't populate in sets of 3, you lose one third of the bandwidth for each missing DIMM. Doing that makes no sense. It also while possible to measure, makes little difference. Having a bit more than you think is enough, enough for the system and apps to cache what would otherwise require a trip to and disk access though does.
    Which is also why the very low latency, near zero seeks, 90,000 I/O's per second - and 1000MB/sec read/write (blade type PCIe-SSD) help a system so much more even after there is "enough" memory today.
    As to what amount and what apps, and $budget$ to determine what upgrades - and upgrades once you get an idea what can be done is rather hard to resist as you can make a huge difference sometimes for $100 here and there.

  • IMac 27" Late 2013 Wi Fi Log in Issue

    Hello everyone,
    I apologize if my questions have been asked in the past. I'm completely new to the Apple Mac OS. I bought a new iMac 27" in the middle of 2014 and use it about once or twice a week and have had no issues to-date. I'm still in the process of learning though so my use of it is limited to basic emailing, web browsing and Skype.
    In the last 2 weeks I have had problems logging into my Wifi network at home. It would not log on even after I had reset the modem. After trying and rebooting my iMac 3-4 times it would finally do so without changing anything in the it. I'm not sure what is causing it, but thought I would ask here.
    What would be causing the log in issue to my Wi Fi network?
    Do I need to be concern with the findings in the Etre check?
    Startup after logging in my password would take longer than usual...what would be causing it?
    Here is the result from the Etre scan. I guess what concerns me is in red...and also if it shows the Wi Fi log in issue.
    Thank you in advance for your help and advice.

    Hi, Jiyujin.  
    Thank you for visiting Apple Support Communities.
    I would need some clarification of the reference to log on and a little more information about the behavior to provide a better answer.  However, here is a troubleshooting article that may help.

    Did you upgradde the RAM? If so, this may be your problem.
    If you want to upgrade to 32GB of RAM on your late 2013 27" iMac and don't want to pay Apple prices, buy the RAM from OWC.
    My iMac, crashed with the first batch of Kingston RAM sourced from an Apple approved service centre. Fortunately I got a full refund then sourced the RAM from OWC and it works perfectly.
    The benefits of OWC are
    1) You can order and ship globally
    2) The price is very competitve
    3) The website clearly states how they test the RAM and the comaptibility with your computers model no.
    4) They have a 30 day refund and a lifetime replacement policy
    5) You can get a rebate on your old RAM, although I didn't bother taking this up.
    Having been through the hassle, using OWC RAM is a no brainer and in my opinion the most convenient and effective upgrade. Hope this helps your decision!

  • Mid 2010 Mac Pro vs Late 2013 Mac Pro

    Hi folks,
    I am currently running an late 2009 8-core MacPro and an late 2013 quad-core iMac. I mainly use After Effects, Final Cut Pro and Cinema 4D for TV and internet motion graphics. While 3D (espescially with v-ray) is getting more relevant in my daily work I would like to upgrade my Mac Pro to a faster system.
    The Cinema 4D community can measure the render speed of a system with a tool called Cinebench. Today I compared the specs of these two:
    12-core Mid 2010 2,93 GHz MacPro with two X5670 processors and the new
    12-core Late 2013 2,7 GHz MacPro with E5-2697v2 processor.
    The 2010 one has a cinebench score of 1400 and the 2013 MacPro has 1600. So they seem to be very close.
    Are there any reasons to spend 2-3000 Euros more for the new Mac Pro when Thunderbolt is not that important and the speed of an GeForce GTX 680 is enough compared to the FirePro cards????
    Thanks for your input....

    Do I have to swap the mainboard too? Or are the sockets the same for the old Nethalem Xenon and the newer Wesmare one???
    You DO NOT have to swap the logic board.  The 2009 and 2010 Mac Pros use the same hardware (main board included).
    The 2010 simply has a modified boot rom firmware that accomodates the Westmere 6-core CPUs and faster ram.
    The only thing preventing you from using those Westmeres in your 2009 is firmware.  Not hardware.
    It should be mentioned that swapping CPUs in a 2009 dual-socket Mac Pro is trickier than the single.  Apple used CPUs without the lids (Integrated heat spreaders).  Your replacement CPUs will have the lids creating a differenc in height when attaching the heat sinks.
    You'll need new thermal padding and you will need to be very careful when tightening the bolts.  Many use washers to prevent over-tightening, though some suggest it is not necessary.
    There are guides online for this procedure.  A bit more of a sweat than the single-socket version where CPU is a simple drop-in replacement.

  • Impossible to share - crashing during export "Out of RAM Memory"   really slow share (Late 2013 Retina)

    Hello all.
    I'm really desperate. I hope you can help me:
    1st) This is my project information:
    on FCPX 10.1.1
    21 minutes. 1080p. 1.64GB file size if "sharing" at 1080p.
    First, it takes AGES to share such size, so I try to export at 480p (246MB). It also takes ages, around 1h30m...    But I this point I'm so desperate, that I just want to "export whatever I can, in whatever settings I can".
    But even trying exporting such "low quality" version of my project, It won't export.
    IT CRASHES!!!! (for the time the project share reaches the 30%)
    How is this possible?!!!! It's a Late 2013 Retina with 16 GB of RAM, "specially updated" for me to use FCPX without too much of a hassle. I could understand a 8GB system doing this, but a 16GB?
    So basically, FCPX shares SUPER-SLOW (which at this point, I don't even care) I need the video to be exported ASAP and be able to acomplish the deadline which was "today".
    But it crashes all the time (when exporting) because of "lack of Memory".     On a 16GB Late Retina which only has Firefox open at the time the video was being exported. (And sometimes I don't even have Firefox open, not even the WiFi is on!) And it also crashes (yep, I've tried to export the project at least 10 times!!)
    - What can I do ? Why is "my memory full", is this normal ?
    More info:
    I have all my project/event/clips  in the MAIN HDD (SSD 512GB)
    Would it change something to have "all my project transfered to an External USB3  HDD?"
    If yes, is there any tutorial on HOW TO transfer / backup the project and ALL files, to an external HDD?
    THANKS!!

    Thanks guys!
    I will try your suggestions right now, so, In order to be sure that I will not f**** up my project during the process:
    1)   Do a backup of my whole project, which only (?) consists in dragging/copying my "Event file" (Library) to the USB3 External Drive.
    2) Delete Pref's with "Pref Manager"
    2**) If the problem continues, delete FCPX / Fresh re-install it, using http://www.digitalrebellion.com/fcsremover/
    3) Just drag & drop the "Event Folder" (37,59GB) from my External Hard Drive, to a new Libary.
    Is this it?
    I would also like to know:
    All my purschased Effects/LUT's/Plugins, if I must Delete & Fresh install, will I have to install them all again one by one?
    Would it be useful to ask for a Genius Bar appointment, before trying all this, or not worth it?
    THANKS!

  • Corsair Ram for iMac late 2013

    Hi,
    I got a new iMac 27" late 2013, and bought 32GB Ram somewhere else. It's 4x8GB Corsair Mac Memory DDR3 1600MHz PC3 12800 (CMSA16GX3M2A1600C11).
    I got several Kernel Panics, but only with the Corsair Ram. Everything seems to work fine if I use the original 8GB hynix.
    Memtest shows no problems with the Corsair Rams at all...
    My questions: Am I right to suggest that the Corsair Ram is causing the Problem, altough memtest shows no problems? If yes, should I return the faulty RAMs and get the same as replacement or would you suggest different RAMs? If yes, which ones?
    Here's the Diagnostic Report from after the last Kernel Panic:

    I'd like to Order via Amazon (it's the easiest way for me) but I'm not sure which one.
    Would someone help me to decide?
    This one seems to be officially compatible with the iMac late 2013: http://www.amazon.de/Crucial-memory-PC3-12800-1600MHz-Macbook/dp/B008LXX9OC
    But this one is cheaper, and the technical Data seems to be the same, but I read already bad ratings about them: http://www.amazon.de/gp/product/B008PSEHAS/

  • Mac Pro (Late 2013) - 64GB RAM Upgrade

    Anyone have any recomendations on third party brand for a 64GB RAM upgrade.
    Apple RAM costs approx £1000 GBP whereas Crucial is approx £645 GBP, OWC is similar to crucial if I import from the US but I'm not sure if their ram are Registered or unbuffered.
    The above is all cost based - should i be considering other factors such as performance and reliability?
    Also when moving to Registered DIMMs i understand that the presence of the Registered DIMM controller on the DIMMs consumes one clock cycle is this a significant hit in performace over Unbuffered DIMMs?

    I don't think so. Take a look at these DIMMs for reference (this Vendor show the specs of exactly what modules will be shipped to you). Even the 16GB DIMMs, while Registered, are still showing they perform at CL9 level (9 clocks to access) -- the same as unbuffered.

    Just thought i would update you. I spoke to DMS Technical Support and apparently that DMS CL9 Rating is a typo.  It should be CL13!

  • Is it possible to upgrade ram for a MacBook Pro Retina, 13-inch, Late 2013

    I own a MacBook Pro 13- inch late 2013 model and wanted to upgrade my memory, but i have read online that this is not possible as the ram is soldered onto the board . Could someone please give me a clarification on this?

    This is correct...
    MacBook Pro with Retina display comes standard with 4GB of 1600MHz memory. Please note that the memory is built into the computer, so if you think you may need more memory in the future, it is important to upgrade at the time of purchase.

  • Macbook pro late 2013's Ram

    Can you upgrade a macbook pro late 2013's model Ram from 8 gb to 16 gb?

    Gnomish8 wrote:
    Yes. It looks like the maximum supported memory for the 15 inch retina is 16GB.
    You can find your systems tech specs here.
    The RAM is soldered into the Logic Board......So technically the RAM can NOT be upgraded on the rMBP.

  • Macmini reboots/restarts randomly (late 2013, SSD internal storage, 16gb ram)

    I just purchased the new MacMini late 2013 model (2.3 GHz INtel Core i7, 16GB ram 1600 mhz ddr3, 256 internal  SSD), Mac OS 10.9.1
    its been in mild usage for a month and in the past weeks I have noticed something whch might have been happening since I got it: it turns off and on again randomly, sometimes when I am in the middle of editing in Final Cut 7 or sometimes when it is in sleep mode... no pattern, apparently. Then it restarts and says my mac crashed and restarted suddenly and offers to send the Apple report, which I have done a few times.
    Since it is a new model, this worries me qa lot: any light to shed on this issue?

    Please make a Genius Appointment and take it in for service.

  • Mavericks on my late 2013 Mac Mini (8gb RAM) does not recognize my APC650CI UPS as a UPS

    I have a late 2013 model Mac  Mini running Macvericks.
    I just bought a an APC Back-UPS XS 650CI for it (I have 3 other Back-UPS 650CI for other systems - Windows 7 and 2x Netgear NAS setups).
    In the Energy Saver panel of System Preferences the Back-UPS 650CI is not recognized, but it IS correctly listed in the USB section of System Profiler.
    I have tried other UPS monitor programs: PowerSave UPS does NOT recognize it, but apscupsd DOES recognize it.
    The Netgear ReadyNAs DOES recognize the new unit (I tried swapping the two Back-UPS XS 650CI's around)
    I have reset the UPS - still not recognized.
    I have tried on of the other Back-UPS XS 650CI's that I have around - not recocognised.
    I have reset the Mac's Pram - still not recognized
    I have reset the Mac's SMC - still not recognized
    I have reset the com.apple.PowerManagement.plist - still not recognized
    My ancient Macmini1.1/Intel Core Duo DOES recognize the Back-UPS 650CI in the Energy Saver panel of System Preferences.
    Thanks for your help
    Andrew

    Answering myself
    Had long conversations with APC/Schneider (quite helpful once you get past the drones)
    They weren't aware of the problem but it does seem that Apple have removed/omitted the code that used to recognize the APC Back-UPS XS650CI at some point after Snow Leopard - Lord knows why.  This despite the fact that it is correctly listed in the USB section of System Profiler.
    The only solutions that I can see is either for APC/Schneider to get Apple to reinstate the relevant code (unlikely) and/or for APC/Schneider to issue an updated version of PowerChute for Mac (long overdue), which is possible but don't hold your breath.
    I bought the (rather expensive) PowerSaveUPS app from the Apple Store but that doesn't work either (http://www.powersaveups.co.uk/) - I've emailed them to grumble but no reply yet.
    In the meantime best bet is to use apcupsd for Mac - it isn't ideal but it works - RTFM. 
    The latest iteration is available on http://sourceforge.net/projects/apcupsd/files/osx-binaries%20-%20Stable/3.14.11/
    Cheers!
