    • Halte das Display gut fest und drücke den Entriegelungsknopf für die RAM Klappe mit dem flachen Ende eines Spudgers ein. Er befindet sich direkt über dem Netzanschluss.

    • Du musst eventuell ziemlich fest drücken. Mache solange weiter, bis das untere Ende der Klappe etwa 5mm weit aufspringt.

    Buenos días!!!

    Cómo le hago si mi iMac no tiene puertita!!! Se tiene que despegar la Pantalla???

    Hello! The procedure depends on the iMac's model. Find the exact iMac for the proper guide.

    ¡Hola! El procedimiento depende del modelo de iMac. Encuentra el iMac exacto para la guía adecuada.

    Arthur Shi -

    No hay que despegar la pantalla para este tipo de reparación. Si no encuentras el compartimento entonces puede que estes mirando al imac equivocado o quizas un monitor.

    • Entferne die RAM Zugangsklappe von der Rückseite des iMac.

    • Der RAM Einschub ist durch zwei graue Clips in seiner aufrechter Position verriegelt.

    • Drücke die beiden Clips mit deinen Daumen oder Zeigefingern vom RAM weg nach außen.

    • Ziehe die Clips heraus und nach unten, so kannst du den RAM Einschub nach unten in eine fast waagrechte Lage bringen.

    • Entferne ein RAM Modul, indem du es mit zwei Händen direkt aus dem RAM Einschub herausziehst.

    • RAM Module können nur in einer einzigen Position eingesetzt werden. Merke dir, wo die längere und wo die kürzere Kontaktreihe ist, damit du später die richtige Position findest.

    • Um ein neues Modul einzusetzen, schiebst du das Modul in den entsprechenden Slot im Einschub und drückst es fest hinein. Drücke dann den Einschub zurück, bis er einrastet.

    • Setze die RAM Verschlussklappe wieder in die Rückseite des iMac ein.

    "Note that the shorter section of contacts should be on the left when installing new modules."

    Mine is flipped so the shorter section of the RAM module is on the right.

    Mine is flipped too… not a mistake, is it?

    Kristi Mathias -

    To add:

    The RAM door is not symmetrical. When putting back the RAM door, it should flush with the back. In STEP 1 photo of the RAM door it seems the RAM door is not fully flushed and aligned.

    Does replacement RAM have to made in “matched pairs”? For example, if I add an additional 32G (2x16G) to the base 8G (2x4G) can the new 16G DIMMS go in any slots or do they need to be placed into specific “matched” slots - (slots 1 & 3 and slots 2 &4)?

    Can I “mix and match” different capacity and manufacturer RAM DIMMS or do they all need to be the same ?.

    richardkpallo -

    From the Apple website for replacing ram in an iMac: https://support.apple.com/en-us/HT201191...

    For iMac’s released 2012 onwards there is no note about the position of ram or matching pairs.

    For iMac’s released 2009-2011 there is this note:

    i5 and i7 Quad Core iMac computers come with both top memory slots populated. These computers will not start up if only a single DIMM is installed in any bottom slot; these computers should operate normally with a single DIMM installed in any top slot.

    Core Duo iMac computers should operate normally with a single DIMM installed in any slot, top or bottom. ("Top" and "bottom" slots refer to the orientation of the slots in the pictures below. "Top" refers to the slots closest to the display; "bottom" refers to the slots closest to the stand.)

    There is a number of comments to say you should stagger the ram and make sure i=identical ram modules share the same DIMM number, not the same BANK number. How to couple RAM Modules in iMac 27?

    Adam Dunn -

    Does ram from iMac 27 late 2013 suit these imac or do i need to buy others?

    Bertil Woltynski -

    Do you know what voltage the OEM ram that comes with the late 2014 iMac is? I just bought some Crucial RAM and was worried about not having the correct voltage and that messing up my iMac…..

    My computer is a iMac 27" 2017 RAM Retina 5k- I want to upgrade my Ram, put 1 -8gig in each free slot, talked with Apple service centre and they want $400.+ for this etc. There must be a comparable Ram on the market I could use that would be compatible to use at normal prices etc. Any recommendations. A computer tech from Apple centre recommended I try you folks.

    Thanks Len

    Hi Len,

    It so happens that we sell the exact RAM you’re looking for at a much lower cost than Apple! Before you purchase the RAM, look over this guide to get an idea on how to replace the modules.

    Arthur Shi -

    Arthur I will contact you for purchase etc.

    walser1 -

    Arthur Shi- my ram is a 260 pin, not 204pin, it is a 27” iMac 2017 Retina 5k

    walser1 -

    Arthur this is what I require, 2X8gb

    Thanks Len

    iMac (Retina 5K, 27-inch, 2017)

    Get memory specifications for iMac (Retina 5K, 27-inch, 2017), then learn how to install memory in this model.

    Memory specifications

    This iMac model features Synchronous Dynamic Random-Access Memory (SDRAM) slots on the rear of the computer near the vents with these memory specifications:

    Number of memory slots4Base memory8GB (2 x 4GB DIMMs)Maximum memory64GB (4 x 16GB DIMMs)

    Use Small Outline Dual Inline Memory Modules (SO-DIMM) that meet all of these criteria:

    PC4-2400 (19200)

    Unbuffered

    Nonparity

    260-pin

    2400MHz DDR4 SDRAM

    walser1 -

    Sorry! This should be the right model. Unfortunately, it looks like we have low stock on the RAM.

    Arthur Shi -

    The good news is that the memory model is common and brand-agnostic, so you can find it online. Search for 8GB DDR4 2400 PC4-19244 260 pin SODIMM memory, and any results should work.

    Arthur Shi -

    What if the ran door isn't back there but everything else is

    Pamela Smalls -

    Is it missing or just no door cutout? If it's missing it's probably not a huge deal, maybe cover it with some packing tape to keep dust out. If it doesn't have the cutout at all, it's probably a 24" or 21" model, much more difficult to upgrade the RAM on those.

I just purchased RAM and this guide was very accurate. Thank you.

Nicole Hamilton -

Hi guys! I have to slot full with the basic amount of RAM (2 x 4 GB), can I install 2 x 8 GB in the other two slots available? I want to upgrade to 24 GB of RAM, but I don't know if there are any problem putting together 4 GB modules with 8 GB ones. I remember an old story about possible issues... Thanks for your replies! :-)

Franz -

You should be fine with pairs of equal capacity. 2 X 4 GB and 2 X 8 GB

Usually best to install in pairs of similar sizes

I just upgraded mine from 16GB to 32GB. The only problem with this guide is that it says the difficulty is moderate. What could be easier? It took me less than five minutes, and most of that was unplugging/replugging stuff before and after the actual RAM upgrade.

I used a screwdriver to push on the little button that opens the door, as I didn't have a spudger handy.

Jake Robb -

Great job, thanks

ventosa09 -

hi, do i need to use RAM specifically designed for Mac? I heard some people have issues after installing RAMs of a random brand even those are of same specs as required by Apple i.e. DDR3, 1600, 204-pin. I found online that OWC is 100% compatible with iMac, what about Kingston? Thanks!

As easy as putting on a new roll of toilet paper… thank you!

I have a iMac 27 inch late 2013 , I replaced the RAM Modules , all good , 5 mins tops , but once the computer was on , it beeped and the screen was black , so I rechecked the modules , one was not quite all the way in , so I pressed it , it clicked in , the computer started , all good , I upgraded the ram to 32 GB , maximum ram , I do not have a lot of stuff on my computer but with updates etc the computer was struggling , all you have to do is make sure the modules click into place, thanks John Mobbs

john mobbs -

The Crucial 16gb for iMAC 2013 DDR3 SDRAM is sometimes mentioned as DDR3 and I have also seen RAM for sale as DDR3L is there a difference between the two? what is the L. I read DDR3 was the correct one.

Thanks for your help.
