Hi!
I got an iMac 27 2013 model. It got the i5 processor. I got an i7 4770S which i know is used in the 21.5’ 2013 models.
Do you guys think I can use it in the 27 inch variant? I know the 27 variant accepts the i7 4771 but neither the i7 4770 or the 4770k, should the S variant work if it’s used in the 21.5 inch?

The Late 2013 27” came in three versions iMac14,2
Your systems BIOS (EFI) is designed to support one of these three CPU’s. The 4770S might work I just don’t know.
Do keep in mind its running at a lower clock 3.1 GHz when installed in the 21.5” system. It might not run at this clocking in your 27” model.

Hello, I personally have installed several i7-4770 CPU on 27” late 2013 iMac and it work flawlessly. Now i´m wondering if the “S” variant would do it too (that is why i got here) and it think they are.
So I don’t have a precise answer for your specific question, but at least i got you close to it, as i mentioned I have done the 4770 upgrade successfully. Now i’m about to know the results when i receive the 4770s I just purchased.

Why are you going with the 4770S version if you already have the 4770 installed?
Intel Core i7-4770S Processor TDP - 65 W
Intel Core i7-4770 Processor TDP - 84 W
The 4770S is really for the smaller system like the 21.5" iMac as its power and cooling is much less.
Hello, so I can put i7 4770 in an imac 27 from late 2013 without problems? I can't get i7 4771.

Just installed a 4770S in my 2013 27 inch iMac and it does NOT work. I can't get past the 1st green LED. This sucks….

As I stated I questioned if it would "Your systems BIOS (EFI) is designed to support one of these three CPU’s. The 4770S might work I just don’t know."
