BGA MacBook CPU upgrade capability

Macbook Pro A1226 2.2 Ghz

I have a a1226 2.2 santa rosa MBP. I have a Intel Laptop CPU T7700 2.4ghz 800mhz FSB from a pull I worked on awhile ago. I've already reballed the chip with leaded solder. I'm about to pull the CPU from the 2.2 MBP I'm preety shure it will fit I'm wanting to know if anyone knows of any problems I would run into as far as the firmware. The a1226 MBP running the Memron chip is already 64 bit so I don't think there would be any problems. In Theory if any chip will fit the BGA it should work right?

Is this a good question?

No, not any chip that fits the BGA will work. I am not going to take the time to do the homework for you, look at the core current and voltage requirements between the 2.


The current Voltage is the same it is just one design chip after it the last in the 65nm Memron intel family. I just having a hard time trying to Core Current any tips?


That should all be documented on the Intel web site or it will be in the schematics for the laptops. There are many utilities that pull that information in the Windows flavor, so you might try a Google on the electrical requirements of the chips. There are lots of enthusiast out there in PC land wanting to overclock, etc... - Apple throttles down and/or over builds most things. So you should be alright. I have come across problems where the power circuit wasn't strong enough for the CPU.


I did not think about this until commenting to Nick. - You may also have the "chip multiplier" that determines the relationship between the CPU and the clock frequency for it's BUS and/or the front side BUS.

It's doable, yes, but you need to find the exact processor socket or model that fits and will work, and you need special BGA rework and reflow equipment

It's too complicated to recommend doing it on this vs a laptop with a socket, your best bet is sell this one to cover the cost of a new Mac, or get a very similar mac to yours with a cracked screen and good logicboard and use that logicboard

if you want to try this, it's your call, i don't suggest it personally due to the difficulty and risk

Think about this

If i upgrade a Toshiba laptop's CPU and it doesn't work too well, i don't need BGA rework and reflow gear to fix it, just 2 screwdrivers, Flathead and Phillips, no BGA reflow gear

+ I agree with you Nick. Not worth trying - unless you have the skills, equipment and little to nothing to lose. - Just a FYI, this will have to be Re-balled for it to work, which means more equipment, experience and expertise than BGA reworking.


I have added this on as of late it needs BGA reflowing too, the toshiba is a scenario I do on my laptops all the time, and i'd rather socket vs BGA in the end anyway
