    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

    i think the cpu in the 27 inch is possible to replace.

    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.
