My 8 gigs of RAM came today! Now I have 10 gigs in my Mac Pro. The first thing I wanted to do was to play a game in Parallels under Windows XP (32 bit, for now). However, upon booting into XP in Parallels and running the game, half the graphics are not displaying (very choppy) and I can hardly even move my mouse it's so slow. I right clicked My Computer and hit properties and it showed only 512 megs of RAM being used. I went into Parallels settings and changed Memory Allocation from automatic to custom and cut the RAM in half by moving the slider to the middle (4~5 gigs for Windows and 4~5 for Leopard, which is fine), rebooted the Virtual Machine and it still showed 512 megabytes, and the game was still slow. I know that my system recognizes the RAM because in About This Mac it shows 10 gigs. Any help? Thanks.
