I recently upgraded my mac pro from 2GB ram to 6GB using 2 additional 2GB modules. (I now have 2- 1GB modules and 2- 2GB modules on riser A and 2- 1GB modules on riser B) After booting the machine up in OS X everything was as planned, and the system information displayed 6GB of installed RAM. However after switching over and re-booting into WIN XP (Bootcamp) the sytem information still displays only the original 2GB. Does anyone now of a way to get WinXP to recognize the new RAM... I really need the resources for 3d VIZ. Thanks.
