is it possible to change a standard cpu (Intel Core i7 4771 LGA1150)
on a late 2013 iMac 27" i7 2gb
to a (Intel core i7-4790K, LGA1150)?
will it work?
ps
please take a look at my other question

While most of the specs line up you do have 4 Watt difference between the two (TDP 84 Vs 88).
I'm not sure its worth the risk to find out if it would work. Remember you'll need to take the system completely apart! I would just leave the CPU alone as the performance difference is not that much.
I don't think anyone has even tried so you'll be a trailblazer if you do give this a try.

i´ve already tried it since i bought the cpu (4970k) yesterday and my imac won't start, I'm just not sure if its the Cpu thats the problem.
please take a look at my other question
Ah! Sorry guy didn't see your other Q. Sounds like they got you good here ;-{
Return the board as it clearly is bad, which is why it was stripped down to begin with. I don't buy unpopulated boards as you never know its history.
A board that has its CPU chip and heat sink was at least from a working system that was stripped for its parts.
A bare board is often what the board supplier offers Apple as a part but it has never had a CPU added so you don't know if Apple return it as a defective board or one that didn't pass QC from the supplier ( dumpster diver find).
I was just checking the same and the advice I discovered but unsure about was TDP 84. You can upgrade the 4771 to TDP 84 not that I found one may not exist or apple applied any intent for an upgrade of this 14,2 model. Here it seems to verify the 4790k I was thinking about upgrading for the little CPU increase because I am getting AAE -6104 errors with Pro Tools. The minor CPU increase may be the exact fix I need. But being a TDP 88. They say "*Officially, Apple provides no information about whether or not the processor in this model can be upgraded and the company does not intend for one to upgrade the processor either. However, the processor is mounted on a LGA 1150 socket and can be physically upgraded with another compatible processor with a maximum TDP of 84 W or less. Hoped this helped. I am no tech and low tech if that. This is what I found.

Here are the specs for the two chips from Intel's ARK site:
- Intel Core i7-4771 Processor (8M Cache, up to 3.90 GHz)
- Intel Core i7-4790K Processor (8M Cache, up to 4.40 GHz)
(8M Cache, up to 4.40 GHz)
