I have a new Dell Precision 690 workstation with a Core Duo Xeon 5160. The BIOS shows the two cores and the 4 GB of RAM ( 4 x 1 GB sticks). In "View System Information" General Tab it notes only 1 Xeon 5160 processor and exactly 3 GB RAM. Should Windows recognize both processors and all 4 GB of RAM? If so, what needs to be fixed to do it?
