Can I upgrade my CPU on my MacBook? If so then how much?
Any help would be great :-]
Thanks!

No. Its soldered to the motherboard.

...so if the logic board dies, they have to replace the CPU also?

Anything on the logic board dies, they basically shred the board and recycle the metals in it.

For a small shop, repairing the ports and the DC boards is economical, but the big chips wipe the board out for most repair shops.

I was wondering this as well. If I took the CPU off of the motherboard, could I replace it with a mobile Intel 2.8Ghz C2D?

Which you can't since it is SOLDERED onto the board.

Yes, it is a simple operation to upgrade the CPU to a 2.4GHz unit and will only cost you $1,599.00 plus whatever Apple CTO upgrades you buy.

You can sell the old laptop when you migrate over to your brand new machine.

If you will to do a DIY job on the old machine, place your nuts in a vise and keep cranking until you decide this is a futile and stupid idea.

How about if you desolder ;)

On a serious note, how about over clocking.. I dont know how hard it is on a macbook as I never looked into it.. But there must be some way to overclock? (not that it would be safe to do on a laptop..)

How about a pat on the back...

On the serious note, there were some people hacking the machines for EFI overclocks of the various parts, though those threads seemed to have died out.

(not that it would be safe to do on a laptop..)Yeah, I was thinking of desoldering but if it's on the bottom of the die it might be more difficult.

Have you thought about how many pins you'd have to desolder? The motherboards are assembled by machine, and they can do solder a lot more fine than any human can. I'd think you are far more likely to trash the cpu and motherboard than get the cpu out and replaced.

There are some crazy people w/ BGA desoldering equipment who have done this before on other laptops. But you risk destroying it very easily, plus this requires alot of skills and specialized equipment. The answer on if you could put a different C2D, is maybe... but no one has tried and posted.

Since the multipliers are locked on most Intel chips, you would need to overclock by upping the bus speeds, that has serious system-wide repercussions.

It would be cheaper buy a new laptop computer than to upgrade it.

Speaking from experience here.

listen. that much heat? desoldering a PROCESSOR? are you kidding?


plus even to find a 2.4 mobile chip would be in the 300$ range... if you sold your computer and then used the money + labor you would have spent on doing that (only to fail) - you would be able to get a MBP.

c'mon now. if you really want to replace a processor go with a previous gen Mac mini.

i.e buy a mini solo core and drop in a 2.33 C2D...
