...to upgrade the video RAM in a 12" 1Ghz Powerbook G4 from 32MB to 64MB or more???
I already know that the VRAM is on the logic board and that it cannot be changed in the same way you can on tower such as installing a new PCI video card. However, what I'm really intrested in finding out is if it is at all possible to upgrade the video RAM by unsoldering the existing 32MB chip and replace it with a more powerfull 64MB chip.
Can this be done? Has anyone already done this and if so could someone point me to some kind of tutorial.
Any information will be greatly appreciated.
