I just upgraded my ram to 8GB which OS X recognizes but Windows 7 32 bit in Bootcamp only recognizes 2.72GB. Of course, Apple only officially supports the 32 bit version but I have heard (see everymac http://www.everymac.com/mac-answers...-bit-64-bit-boot-camp-support-intel-macs.html ) there is unofficial support for the 64 bit version with the right drivers. Anyone know how?
