hey, i recently bootcamp my imac 2011 for windows 7 32 bit. when i go into system on windows 7 it tells me. "installed memory (RAM): 8.00 GB (2.23 GB useable)". why is it only using 2.23 GB when i got 8.00 GB installed? is there a setting on windows or mac OS that i can change to how much it can use? mind you its the 8 GB sticks i ordered with the imac when i ordered it from apples online store.
