BGA478 & PGA478... Are they Inter-Changable???

[ddamico203]

So i have an ollldddd acer aspire 6930 with a BGA478 Intel core 2 duo T5800, and wanted to pump it up to a faster chip in the 8xxx or 9xxx, but they are PGA478 socket, are they interchangable or are they incompatable???

Ooh, there was a thread about this not too long ago: http://www.tomshardware.com/answers/id-3652358/laptop-cpu-upgrade.html
Third post says that you can't replace BGA, but PGA is.

No, they are not. While there are individual users who have successfully replaced a BGA CPU, it requires some extremely advanced soldering skills. And you'd replace it with another BGA CPU, you can't swap to one with a pin grid array.

If you still really want to do this -- I'd recommend strongly against it -- there are a number of reballing tutorials on YouTube. I would definitely suggest practicing with a few broken laptops first before even trying this procedure on hardware you actually hope to use in the future.

BGA is soldered to the board.
