    I have done some research and found out nothing about doing this mod and nothing about which chipset the iMac uses.

    I tried to see If anybody tried upgrading to a Q9550S since that would mean it could support a L5420 via socket mod but nope, nothing about Q9550S being used on an iMac. In fact, I couldn't find anything about using quad-cores.

    A L5420 would be much better since it's 200$ cheaper and pretty much the same thing but L5420 has a lower TDP

    Do you think UEFI would give me any firmware problems, If I tried a quad-core?

    Also, yes, I know only the RAM is suppose to be upgraded by the end user, I could get a decent value out of my iMac and yada, yada, yada...

    Has anyone done any sort of CPU upgrading with 2009 iMacs?
