I have a Dell Precision T7400 Workstation with 3.4 GHz Dual Xeon 5492,32GB RAM,1000GB SATA Drive,150GB SATA bootable drive,NVIDIA Quadrro FX4800 1.5 GB and XP 64 OS.Whenever i use 3DS Max 9 the system does not use more than 12-13 GB of RAM.How do i get it to use at least 28 GB considering that i spent a fortune on the high end variety for rendering?
