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.

Ich habe diese Anleitung genutzt bei meinem 27“ late 2013 Mac. Zu den vorhandenen Speichern von 2x4GB habe ich in die leeren Slots je einen 8GB Speicher eingesetzt. Das ging problemlos so wie beschrieben. Habe kein Werkzeug gebraucht. Die Taste zum Öffnen konnte ich mit dem Daumennagel hineindrücken. Der gesamte Speicher wird mit 24GB angezeigt. Vielen Dank für diese Hilfe!
Hello. My Imac (27-inch, Late 2012) has the original memory (2x4GB Elpida) in slots 1 and 2. When trying to install in slots 1+3, 1+4, 2+3, 2+4 it beeps three times and the Mac does not start. Replacing the original memory in slots 1+2 with new memory (2x8GB) is successful. Can not add memory to slots 3 and 4 (old memory or new). Please advise where to look for the problem.
Buenos días!!!
Cómo le hago si mi iMac no tiene puertita!!! Se tiene que despegar la Pantalla???

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.
