Mine is flipped too… not a mistake, is it?
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 ?.
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?
Does ram from iMac 27 late 2013 suit these imac or do i need to buy others?
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 I will contact you for purchase etc.

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
Sorry! This should be the right model. Unfortunately, it looks like we have low stock on the RAM.
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.
What if the ran door isn't back there but everything else is
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.
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! :-)
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.
As easy as putting on a new roll of toilet paper… thank you!
I have a Question: are hynix 2gb 1rx8 pc3-10600s-9-10-b1 ram compatible with a iMac Intel 27" EMC 2639? they came out of my Late 2011 13” MacBook Pro ( I did the ram upgrade) My wifes imac has been very slow since she upgraded to Catiline. Moneies tight I was just wondering…
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

there is another setup for older imacs that have a screw cover on the bottom of the unit not on rear. have changed ram getting three beeps when I know the rams good any suggestions white screen of death three beeps till you power it down .
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.

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

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.
