On all iMacs – with the exception of the latest 24 and 21.5-inch models – the RAM itself can be upgraded, which is a quick and effective tuning. Inserting the memory modules is done quickly, but it is a bit more difficult to find the right modules for the respective iMac.
Therefore, we have selected suitable RAM modules for the corresponding iMac models listed by year of manufacture and model name, which you can use in your iMac without any problems. You can see which iMac you have by going to Apple > About this Mac in the menu bar. Then you can search for the right RAM in our overview.
