sooooooo got home. there was my new mac pro. brought it upstairs. removed the old mac pro (by old I mean 3 weeks old). then put my hard drives from the old mac pro into the new one. added my ram to the 1st 2 slots then put the new mac pros apple ram to the second 2 slots. then booted. everything went fine. then I checked ram. only 4 gigs was showing up. (first slot on each ram card) shut down. removed all ram. put apple ram in first 2 slots. mine in second 2. reboot. only 2 gigs shows up(2 1 gig sticks). removed all my hard drives. put the one that came with it back in. booted into the fresh new OSX. still only 2 gigs. Im at a total loss here people. anyone have any idea what to do? is this one defective too????
