iMac EMC2805 Logic Board Replacement

I have a 21.5” iMac Mid 2014 A1418 with logic Board 820-4668-A which is faulty.

Looking for any alternative logic board I can use which will work in this system.

Also one that can support upgradable memory and/or blade SSD supporting logic board.

Were you able to find an alternative compatible logicboard? Or were u stuck having to replace with the same one?

I found a 1.4 GHz Logic Board that supports a blade style SSD on an external site (iFixit is sold out) but you are limited to 8 GB of RAM because it is soldered to the Logic Board. I did a pretty widespread search but found no compatible Logic Board that you can upgrade the RAM on. You will need to replace the display adhesive strips and I have included a link to buy them below too.

Thankd for the answer is this model has any fixing issues on iMac cabin

Hold on! @ajcooke01 - The logic board you pointed to has fixed RAM and does not offer SSD support!

@rajiv8047 - Lets find a better board!

@danj you aren’t going to get much better then fixed RAM, the one I just updated the link to has SSD support.
