Upgrade CPU on MacBook Pro Retina 2.3 GHz

Just heat up your board for 48 hours @ a good low temperature, grab your $80,000 dollar rework station, and try out a new, faster cpu! :) report back here with results. cmon its easy ! Haha..

I believe it just takes more skill set and knowledge about electronics, processors and computers altogether! (not that its impossible to upgrade the cpu..) you just have to lift it off the board at high temperatures .. (It gets all sciencey...)

Get a desoldering hot air gun or rework station. A good one can be found under $100. The high end ones ($600+) are for people who intend to make a business out of fixing motherboards etc. I've done solder rework on a BGA chip cellphone and repaired it. Simple IF you have steady hands.

I have the same question. BGA resoldering isn’t a concern, there’s another tricky thing - EFI and configurational smds on the board. For instance, if you want to upgrade RAM it’s tottaly doable except you MUST KNOW which smd configuration is needed for your new setup, so you have to change it in a very special way.

Is that the same for CPU? Or the work is to simply resolder the new chip?

Wow. This Dan guy must work for Apple or so. He really dont want anyone to think it is possible to upgrade a cpu.

I managed to upgrade my i5 to a i7. Bga pins on a series of cpus like haswell for example are all the same. No different pins.

I used a Haswell i7 from an death Sony Ultrabook Mainboard - CPU rarely gets damged on a Mainboard.

U just have to flash SMC with a donor file and ur good.

That's an incorrect answer actually. Not all laptop cpu's are soldered in and most of them are up gradable . That being said the mac book pro retina is soldered in. However you can upgrade the ssd. Ive also heard that if you are still under warranty you can purchase upgrades through apple .

If you would like help upgrading , feel free to contact me at Steven.krupski@live.com

@ mac It is relevant to the problem as the user was asking about a possible upgrade.

Knowing that not ALL CPU's are soldered in may help them in their decision.

I was just quoting your earlier comment and clarifying. If you don't understand the importance of giving clear information then the problem is with you and not with me .

Possibly misleading the end user is simply incompetent and only troubling to those involved. Any professional would agree that being precise and exact when you give advice is a must.

@Dan So once again not ALL laptops have soldered in CPU's in fact most of them don't. Intel isn't the only one out their also that is not the case with the pin gate arrays (PGA),

Perhaps your time would be better spent learning how to deal with end users and bettering your relationships with others instead of arguing over someone else's statement that had nothing to do with you in the first place.

Now if you had listed some other models that have soldered CPU's or laptops that have upgrade potential that would have been helpful.

Throwing a few models that are soldered isn't really relvent in the context applied nor is it making you sound any smarter.

There is no way upgrade the processor unless you know what you're doing with a soldering iron and some magic.
