I bought a powerbook G4. The ram is 512 mb but i want to upgrade that. Is it possible to place two 1gb cards in each slot. That i have a total of 2gb ram? Me was told that the max of the powerbook G4 is 1 gb. Is that true? And when it is true, is it smart to buy a total of 1gb for the powerbook g4? Or doesn't make that any difference? Sorry for the bad english! and thx for helping me!
