XPS 8500 Virtualization

I am trying to determine what I have to do to get virtualization working on my XPS 8500.  According to Intel the I7-3770 supports Virtualization Technology.   Intel Processor Identification Utility shows that Virtualization is not supported on my i7-3770 @ 3.40GHz..  Intel community forums indicate that chipset or motherboard incompatibility.   My motherboard is a Dell 0NW73C (CPU 1).  The chipset is an Intel Ivy Bridge, Revision 09.  Southbridge vendor: Intel, Model h77, revision 04.  I don't know what to beieve. Can anyone tell why virtualization will not work and what I need to change to get virtualization working on the computer.
