Upgrade of base model iMac 21.5

Hi everyone !

I got a new base IMac 2017, below characteristics:

  • 2-core Intel Core i5 7-generation 2,3 GHz, Turbo Boost up to 3,6 GHz,
  • 8 GB memory
  • HDD 1 ТB
  • Intel Iris Plus Graphics 640
  • Thunderbolt 3
  • Screen resolution1920x1080.

Nice system, but there are few things I don't like and would like to improve:

  • HDD - So slow, that sometimes drives me crazy
  • RAM - 8 GB, take into consideration that it is shares with video - sometimes not enough
  • Processor can it be changed? - Just optional

So my questions are?

  • What maximum SSD storage can be installed in SATA connection?
  • Is there any PCle connection to connect blade SSD (M.2)?
  • What maximum RAM that can be installed 16, 32 GB?
  • What is the most powerful process that can be supported by this motherboard in stead of 2-core Intel Core i5 7-generation 2,3 GHz (may be I 7 4 cores ..etc)? but this is optional.

Thanks for answers.

Your system uses a 2.5” SATA drive as far as what is the largest I think you could go upto 12 TB but I think thats a bit much ;-} and very expensive! A more realistic size would be 1 or 2 TB like Samsung 860 EVO SSD

As far as adding a blade SSD, not possible as the socket is not installed if you got an HDD only system. Only the SSD or Fusion Drive config systems have it. FYI its a custom blade drive its not an M.2 which is similar.

As for upgrading the CPU its soldered and not upgradable either! Sorry

The max RAM is 16 GB as your system only has 2 SO-DIMM slots. Here’s the IFIXIT guide to get to them iMac Intel 21.5" EMC 3068 RAM Replacement. Make sure you get the proper tools to remove the display as its very easy to damage which would be an expensive oops!

Thanks, Dan for clear answer! Now its clear for me - 16 G RAM maximum, SSD 1-2 Tr. Processor not changeable. I think replacing HDD to SSD and change RAM from 8 to 16 should be enough to make this piece of ..metal works normally. (I still wondering, how it possible to make nice beautiful comfortable computer with really scrap inside?)

Just a note, this model is actually capable of 32GB of RAM, as that is what I just put in mine and it sees all 32GB no problem.
