Hi all. I currently have a macbook that runs on 1gig dd2 667mhz ram. I wanted to upgrade it to 2 gig. My problem is that after i upgrade my ram, I have 2 512 meg of 667mhz ram. Can i install this ram into my inspiron 9300?? The inspiron runs on ddr2 533mhz ram. I think it also have the same number of pins as my macbook. If it fits, would it damage my laptop??? I wanted to know this before i upgrade. Thanks a lot
