Answer to: RAM upgrade from 1066 to 1333 MHzHi, I have a late 2008 unibody aluminium macbook. i want to upgrade to 8Gb(2X4) My MB specs specify 1067 Mhz. I´been told and read tons that with 1066 it works OK... ! can somebody tell me By own experience if this is true? In the mac store i`ve been told that if you put a 1066 or 1333 it won't work appropriate because of the bus or something like that... i am really confused, and don't know which one to buy!! i really need to upgrade it, as my MB is SUPER SLOW since i installed Mountain Lion!!
