Can I upgrade my Late 2012 iMac i5 2.7 GHz CPU to i7 3.1 GHz CPU?

Can anyone confirm this iMac (21.5-inch, Late 2012) - Technical Specifications

Since it mentions you can upgrade if you have the i5 2.9 GHz (i5-3470S) to the i7 3.1 GHz (i7-3770S) but not if you have the i5 2.7 GHz (i5-3330S).

Does anyone have an experience upgrading their CPU i5 2.7 GHz to the i7 3.1 GHz and did it work and boot?

Thank you very much.

Often times Apple gets cheap on the 21.5” models by soldering the CPU's Vs offering a socket.

The 2012/13 21.5” model is a rare exception all four versions offer sockets iMac13,1 - Late 2012 & Early 2013 21.5 models

As long as you stay within the CPU’s this series used you should be fine. I personally have not upgraded the 21.5” 2012 systems, I have upgraded the 27” and didn’t have any issues.

Do keep in mind you can damage the display just in the process of taking it off if you don’t use the proper tools and techniques outlined in the iMac Intel 21.5" EMC 2544 Logic Board Replacement guide. This is not an easy job so make sure you are up to it.

I upgraded EMC 2544 late iMac 2012 21,5” with I7-3770s 3.1Ghz and it works fine. In combination with 16 GB RAM and SSD it was a major improvement :)

I did it 6 months ago, I went with the i7 -3770 3.4ghz

it burnt out 3 days ago and threw the SMC out.

Its performance wasn’t that great as it would run hot upto 100c under load.

stick with the lower powered 3770S and you won’t have a problem. they are plug and play, don’t forget to order a sticker kit to put your screen back nice.

I just put my old 2.7ghz back in and its running faster with temps below 50c.
