A reader recently asked me which Apple iMac I would currently recommend to buy. My recommendation is the Apple iMac 5K with Retina display and Fusion Drive from 2017. However, most retailers only find this in the version with 8 GB RAM, which I personally think is too little memory. You can of course also buy it directly from Apple and order the version with 16, 32 or 64 GB of RAM. But the latter costs 1.680 euros more. Then upgrade yourself! How and by what means, I'll show you in these instructions - you can also find a video with step-by-step explanation here;)

Which RAM bar can I use?
Before you start tampering with the hardware of the Apple iMac, you have to know which RAM bars you can install. It is important to know that there are 4 slots that are factory-equipped with at least 8 GB (2 x 4 GB bars). If you want the maximum RAM of 64 GB RAM, then use 4 x 16 GB bars. These not only have to be SO-DIMMs (Small Outline Dual Inline Memory Modules), they also have to meet these criteria:
- PC4-19200 (2400 MHz)
- without a buffer
- without parity
- 260 pole
- 2400 MHz DDR4 SDRAM

iMac Retina 5K 2017 upgrade memory / RAM
The individual steps for upgrading memory on the 27-inch Apple iMac from 2017 are super-easy. Anyone who is not exclusively gross motor predisposed and has a bit of instinct will definitely manage it. The only tool - besides the hands - is a slotted screwdriver or other flat tool to press a button. Furthermore, nothing has to be screwed on or otherwise disassembled.
So if you have checked your (new) Apple computer for functionality and it works as it should, then the new memory bar can be installed. Proceed as follows:
- Step 1: Turn off the Apple iMac and let it shut down
- Step 2: Unplug the power cord from the back of the device
- Step 3: Press the button above the power cord slot so that the flap above opens
- Step 4: Remove the flap to expose the RAM sled
- Step 5: Push the gray levers outwards and fold the slide down
- Step 6: Pull out the existing RAM bar and keep it safe (do not touch the contacts)
- Step 7: Install new bars with more memory
- Step 8: Push the slide back up and let it click into place
- Step 9: Put the flap on it and connect the power cord
- Step 10: Turn on the iMac and verify correct RAM installation
