processor support for virtualization purposes (Virtual Machine Exten-

that are too deep. The larger the number behind the
"c", the deeper the hibernation state, the less the
power consumption and the longer it takes for the
devices to switch on again from the hibernation state.
For example, the setting C6 allows the C states C1,
C2 to C6 to be adopted. The possible other C states
C7 are prevented.
Enabling turbo mode (Enabled). When enabled, the
processor can use Intel Turbo Boost technology to
increase the clock speed when the operating system
requests more power.
To use the Turbo mode effectively, the performance
modes of the "P-States (IST)" processor and energy
saving modes of the "C-States" processor must be
enabled.
Disabling turbo mode (Disabled).
The turbo mode is enabled if its supported by the
2
CPU, otherwise it is not enabled.
The CPU is operated with maximum power. A higher
temperature development is taken into account,
without regard for the ambient temperature.
When using the device in higher ambient tempera-
tures. As a result, the CPU power consumption is
reduced in favor of a higher permissible ambient
temperature.
