4770K Physical Damage repair

slomo4sho · Jul 26, 2013

It was bound to happen eventually and this time around the delidding of the 4770K resulted in physical damage to the chip. The processor no longer POSTs and damage seems to be associated with the system agent, display engine, and memory controller portion of the chip. There are two missing components on this end of the die and repair of these two components should restore functionality (theoretically). However, my difficult is in trying to have the chip repaired.

Can anyone recommend any specialist or business that would be able to refurbish this chip for me?

I'm not an expert on this, but I believe you voided the warranty. Therefor, I dont think you can get help from intel. As for a specialist, you should look around in your area. Search around google. Good luck!

You messed up man intel warranty would be void but u can try by fixin the lid and talk to intel claiming the chip is not wrkin this is the best try u can give to it

Hope this works fr u

MylesMPC :

I am aware of this. That is why I am looking for a 3rd party repair.

Repairing a CPU seems like a doomed path to me. Intel doesn't go around selling parts from its CPUs, so it'd be extremely difficult to find those parts. Also you're working with technology that goes to the micron, so it would be incredibly difficult to even repair the thing. The way I see it, you're only option is to replace the chip.

I have a Athlon II X4 760K being shipped from the UK for a test build (I have been recommended the 750K and 760K so I want to see the chip performance first hand) which I can use until steamroller/broadwell is released if the the chip can't be repaired. I also have an extra 3770K and 3930K laying around which I can utilize if the overclocked 760K lacks acceptable performance.

The external damage may be repairable so it is worth the effort. I may need to take the chip to a jeweler to fix the two damaged component links if I can't find a CPU expert.

My advice would be to recycle the chip.
Especially today, CPUs aren't Intel 4004s. These chips pack billions of microscopic transistors, and when you start messing with the externals and internals you can irreparably damage the chip. Even a scrape from the tip of the tool you're using that you can't even notice could destroy part of the circuitry. The only thing you'll end up with is an even more damaged CPU, so do yourself a favor, sell your extra CPUs and buy another 4770K before you end up with one incredibly mangled CPU.
Also: External damage to the heatspreader throws off the heat spreader. Fixing it will cause microscopic defects that will cause the already hot Haswell CPUs to become hotter, damaging the chip further and maybe even rendering it even more useless.
