Q. What RAM memory and hard drives fit my Mac PowerBook G4?

Posted on February 20, 2012 by quill

The Powerbook G4 was a revolutionary notebook when it was released, having an all-metal casing manufactured with a Titanium alloy. In Early 2003 Apple switched to an aluminum allow for the case, and introduced 12″ and 17″ models. At the same time, they changed from PC133 SDRAM to DDR memory.

The main thing to watch for in later PowerMacs is the Late 2005 model, it has the same speed as the model it replaced, but changes to DDR2-533 SODIMMs
