I'm running a brand new Late 2012 i7 iMac with Fusion Drive, 16GB of ram, etc. I just put a bootcamp partition with WIndows 7 Pro x64 on the Fusion Drive today and after all the drivers and updates were applied the system does not allow usage of the full 16GB installed in the machine (this was also the case prior to driver/updates installation). Can anyone supply a solution or a reason why this is the case?
