View Full Version : new iMac memory used for Powerbook Memory?

May 17, 2008, 01:38 PM
Hello I just got a new intel iMac and I upgraded the memory from a 3rd party. So now I have 2 1gb memory sticks just laying around, and I was wondering can I use one of them in my powerbook g4? Will it be compatible? I am pretty sure it would be but not 100% certain and that's why I am asking here.

No, they use different types of RAM.

iMacs use DDR2 memory.


It looks like they very last revision of the G4 Powerbook uses DDR2 RAM

Both the iMac and Powerbook uses SO-DIMM modules (laptop memory).

I don't know what revision you use though. However, DDR2 RAM will not work in DDR slots. DDR RAM won't work in DDR2 slots. There is no compatibility between them.
