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.

At the end: "To reassemble your device, follow these instructions in reverse and use our adhesive strip replacement guide to reattach the display glass."
This does not make sense for a memory replacement guide.
I made a few changes to the guide to make it more readable. Thanks for the tip!
I am thinking about getting me an iMac 5K but not really interested in overpaying for my RAM - can I access all 4 slots in the newest iMac 5K so I could buy the entry level with 8GB and then upgrade it to 32GB myself?
Yes, but make sure they are the same frequency so there won't be any issues. (1867)

Hey.... when i add new Ram... does it matter go it goes in? what i mean is I have 4 slots.
2gb, 2gb, 2gb, 2gb
Can i put in
2gb, 8gb, 8gb, 4bg ?
Mixing and matching is usually not recommended ... even if the clock speed and voltage are the same, it's best if the timings are also the same, and even then, it's not guaranteed that two different sticks will work together. Most of the time they will, but you don't want to be one of the 20% or so where it doesn't.
Kindly advise if this model of RAM will fit in the iMac 5k Retina?
Kingston HyperX FURY 8GB 1866MHz DDR3 CL10 DIMM - Blue (HX318C10F/8)
no, yahujee, that particular RAM is for desktops (DIMM). iMacs use RAM that is the same size as laptop RAM (SODIMM)
Hi, How can I tell the frequency of the RAM? The label says OWC1600DDR3S8GB and a serial #. Bill
Hi is - HyperX 32GB (4x8gb) 1866MHz DDR3L CL11 SODIMM - supported by iMac 5k retina 27" i7 4Ghz? thnx
did u test it?
Hi the latest imac 5k retina does it use the same method to upgrade ram?
Please Tell Me:
Can I install only ONE (1) 8GB stick, besides to the original two (2) 4 RAM sticks that came with my iMac 5K Retina 27”? That will turn the RAM to 16GB; the other slot will remain empty for future expansion; is that OK??
I have IMAC 27in 5k 2020 Model, and I have just bought 64GB Kit DDR4-2666 SODIUMM and I have tried putting the ram in multiple slots and various ways, yet its still not starting back up, So I keep having to remove my new ram and just use the 8GB I bought the mac with, Any Suggestions?
I've installed a 64GB kit in my iMac 27", in addition to the default 8GB. Although the Kit says they're DDR4-2666, in About This Mac it's showing as DDR4-2133. Is it because I've not paired the slots correctly?
Very very disappointing for an iFixit guide. It's extremely scant on necessary detail. Can SODIMMs be added individually or must they be in pairs? Which slot is which? Which bank is which? Which slots do I use for matched banks? What are the minimum and maximum capacity?
This is nothing more than the beginning of a guide. It's an introduction, not a guide.
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.

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.
