I want to replace the RAM
Hi- I am attempting to replace the 1G of RAM I currently have. I am reading in Macworld about ifixit. It says I have 4G I can put in...do I buy 2 2G RAM cards? One for each available slot or is there a 4G RAM card I need to buy...please include the part numbers for the parts I will need to answer my question so I can buy my RAM from you guys. Thanks.
