PE 2850 and Xeons and Hyper-V

I have a PowerEdge 2850.  It will run Windows Server 2008. 

It will not run Hyper-V.  I want to run Hyper-V.

Stock, the PowerEdge 2850 has a Xeon ___(What is the codename of this processor?)____.  It is 8G and does not support VT-x in the processor, I need at least a 9G (I think?) that does support VT-x in the processor in order to use Hyper-V on Windows Server 2008.

What would that processor be called?  (The Codename)    Would that processor I need run on this motherboard?

thanks
