Hi everyone

I loved the thread here about the iMac 27" 2012 CPU upgrade story. I did it also when i had the 2012 iMac.
Now i have the latest i5 haswell and would like to upgrade from i5-4670 to a i7-4771
Anyone done that or know how to… or if its possible.

I already installed the SSD but now i would like to try the CPU also.

Thanks for all the great stuff in here already. been very usefull for me :D

Unfortunately, the haswell iMacs have a soldered processor.

EDIT: Well that only applies to the 21 inch.

Hello,
I see the i7 27 inch stock comes with a 4471 CPU.
In the stores I can only seem to find either the 4470 or the 4470k.
What is the difference between the 4470 and the 4471 and would a 4470 work on an iMac?

Cheers!

Only the 21.5" haswells have soldered processors.

The 27"s are perfectly upgradeable.

It's 477x, not 447x.

The 4771 is basically a 4770K without the unlocked multiplier to enable overclocking.
