I'd say that if you can swing it, get 32GB.
Plus, if you do have that one intensive application for work or school that needs a lot of RAM (and that could be Chrome), the more you have, the less your system chugs to a halt when you're using it. More RAM makes it easier to have more applications open at once, have more browser tabs open, can lead to faster waking from sleep, and can just help your computer run faster. Why? Because your work is going to be more intensive than you think it is.

While you can get away with 8GB if your computer use is relatively light, if your iMac will do any amount of work, either professionally or for school, you'll want to upgrade to at least 16GB of RAM. How are you going to use your iMac? Most people will be fine upgrading to 16GB of RAM. When thinking about how much memory you should actually get, it comes down to a question of purpose. Every other spec is going to be the same except for the actual amount of memory you get.
You shouldn't notice a difference.Īs long as the RAM you get follows these specs, the only decision you have to make is about capacity. It has more to do with how some companies round a particular memory value than any actual spec. This memory is still compatible with your iMac. Instead, you'll find RAM with PC4-21300, but don't worry. Now here's the thing: nobody sells RAM marked with PC4-21333. The memory that you get for your iMac, and indeed, everything we've recommended, has to have these basic specifications: The exciting news for iMac owners is that you really only need to worry about capacity. While I would recommend spending money on a better graphics processor or more storage before you buy a RAM upgrade, memory is still worth upgrading if you can. When buying a memory upgrade for your iMac, my first piece of advice is the same for any other component: buy the best you can afford. Get the Timetec Hynix 128GB RAM set instead and it's only $647. For instance, if you need a massive 128GB of RAM in your iMac, it'll run you an additional $2,600 if you choose Apple's upgrade option. So, why do you want to go with third-party RAM at all instead of buying more RAM when you order your 27-inch iMac? It comes down to cost.
