Despite the Apple documentation claiming that 16 is the maximum capacity for this model, I researched and found that you can max out to up to 32 GB.
For those people that have no clue (like me), the installation was really easy:
1 - Turn off your iMac. Touch the iMac frame to discharge you (electrostatic), and unplug it from A.C. Place your iMac "face down" in a towel.
2 - unscrew the 3 bolts from the memory bay at the bottom of the iMac, remove the memory cover.
3 - leave the 2 RAM modules in their slots (I had 2 RAM modules, of 2 GB each).
4 - Insert the NEW 2 RAM modules (8 GB each) in the 2 available slots.
5 - Screw the 3 memory cover bolts, get it up back in place and turn it on. That's it.
By looking at the "About this Mac > Memory" screen, I went from:
[ 2 GB ] [ 2 GB ]
[ ] [ ]
[ 2 GB ] [ 2 GB ]
[ 8 GB ] [ 8 GB ]
Hope this helps!
This was an easy fix and an easy task to complete for someone who is usually not comfortable doing these kinds of things with electronic devices. The process takes about five minutes and is carefully explained in full detail in manufacturer's pages and in helpful YouTube videos available everywhere. Everything worked exactly as prescribed without any glitches or unexpected problems. So, again, "do it now" if you are having problems with your computer and have only the minimum memory supplied by the manufacturer. That's not enough for today's programs, apps and operating systems, and this fix really works.
OS X Yosemite 10.10.1
Wanted to upgrade from the base 4GB of RAM provided by Apple. Looking for better performance. Interesting problem upon installation.
Attempt One: Original two 2GB DIMMs were in BANK 0/DIMM1 and BANK 1/DIMM1. Added the new Crucial 4 GB DIMMs to open slots for BANK 0/DIMM0 and BANK 1/DIMM0. Upon startup, the iMac blared the warning horn. Annoying sound. Had to power down holding the power button.
Attempt Two: Swapped one each of the two sets so the DIMMs were in the same banks. Once again the horn alarm upon startup. Power down . . .
Attempt Three: Loaded only the new two 4GB DIMMs in BANK 0/DIMM1 and BANK 1/DIMM1. Booted up fine. “About this Mac” showed 8GB total RAM. Success with new Crucial RAM.
Attempt Four: Keeping the two new Crucial 4GB DIMMs in BANK 0/DIMM1 and BANK 1/DIMM1, loaded the two original 2GB DIMMs into the DIMM0 banks. Booted up. Worked fine. “About this Mac” showed 12GB total RAM. This was the intended end goal. Success with both old Apple/Samsung RAM and new Crucial RAM.
Odd that the old RAM had to be relocated to the open slots. Specs between old and new did match, DDR3 1333 MHz. Have always had success with Crucial RAM in both PCs and Macs. Will continue to recommend Crucial.
Hope this helps other do-it-yourselfers.
I went with 16GB-ram upgrade, 4x4GB, and the difference is breathtaking. Although we should agree that such quantities of ram should be unneeded on a UNIX-compliant system, it has kept me from prematurely upgrading to new hardware.

Many of you will now know that the older iMac ranges, which originally were said to only allow a maximum of 16GB, can, in fact, take up to 32GB of RAM.
My advice, if you can not afford a new machine right now, is to spend some of that furlough money on more RAM. It's given my Mac a new lease of life. So much more breathing room to have multiple apps open and the fans are not running so much because I'm not asking the machine to do too much.
I used to buy directly from Crucial but check Amazon and noticed that they were listing the same RAM for cheaper, so I back-ordered and waited about 1 month for it to arrive. Well worth the wait to save an extra £10.
A store quoted me 300 pounds to do a motherboard repair. After some research online I found I was able to check if it was the RAM, or the RAM ports thats were faulty.
One of the RAM ports in my macbook was dysfunctional. I was able to replace this and leave one slot empty and have managed to make my Laptop work fully again.
I dont know how long this fix will last but it was well worth the 40-50 pound spend to get all my computer files re backed up!! :)
Very happy! And this Crucial 8GB is apparently the max a slot should hold.
Effect - instantaneous. Much quicker response times - no hanging around waiting for things to happen.
I phoned a company to do the job and they were charge £50 for installation! So, I had a quick google/youtube search and attempted it myself. Well, it was a breeze. Turn off the laptop; Remove the back; press plastic tabs holding the ram in place; remove rams; insert new rams the same way you removed the previous ones; click back down until the plastic holders hold the ram holders in place; screw the back back on; turn laptop on. Honestly, it was super easy.
So far it’s a lot quicker than it was prior to installation! If I can do it, I promise anyone can.
