Graph in task manager

[gorakh nath]

I have core 2 duo e8400 cpu. But in task manager only one graph is shown whereas both cores are enabled. What to do?

This is average though cores, I think you can double click it or rightclick and show details ?

Right-click the graph and change it to logical processors instead of overall utilization.
