Info:
To operate the processor within the
specified values, we recommend
not changing the default setting
(TM1 and TM2).
TM1 and TM2 Intel Thermal Mode 1 and 2 enabled.
If the CPU reaches excessive temper-
atures, TM1 reduces the processor
speed by 50% and TM2 activates the
Intel SpeedStep technology.
Enabled Enables this function. Use XD Capability This option is a safety feature that pro-
tects specific data regions of the system
memory from potentially damaging code.
Disabled Disables this function.
Enabled If the function is enabled, a virtual ma-
chine can use the additional hardware
capacity.
VT Support Option for activating or deactivating a vir-
tual machine.
Info:
You must restart in order to apply
changes made to this setting.
Disabled Disables this function.
Enabled Enables this function. SMRR Support The SMRR (System Management Range
Register) limits cacheable references of
addresses in SMRAM in order to keep
the code running in SMM (System Man-
agement Mode).
In some circumstances, an intruder who
is loggeg on as administrator could con-
figure the Intel processor to gain access
to the SMM. Implementation of SMRR re-
duces this risk of unauthorized access.
Disabled Disables this function.
Enabled Enables this function.
The processors are run at different fre-
quencies, thereby saving energy.
C-States This setting allows the operating system
to set processor clock rates on its own,
thereby saving energy.
Disabled Disables this function.
Both processors are run at the same
frequency.
Enabled Enables this function. Enhanced C-States
2)
This setting allows the operating system
to set processor clock rates on its own,
thereby saving energy.
Disabled Disables this function.
Enabled If ICH receives a Bus Master request,
then the system changes from C3/C4
state to C2 state and the Bus Master is
automatically activated.
C-State Pop Up Mode This setting makes it possible to de-
tect Bus Master requests and to assign
processor clock frequencies. This can be
done to save energy.
Disabled Bus Master data transfer is a Break
Event and ICH will attempt to return to
the C0 state.
Enabled If ICH does not receive a Bus Master
request, then the system will be set
back to C3/C4 state.
C-State Pop Down
Mode
3)
This setting makes it possible to de-
tect Bus Master requests and to assign
processor clock frequencies. This can be
done to save energy.
Disabled ICH will not attempt to automatically re-
turn to C3/C4 state.
Enabled Enables this function.
CPU voltage is reduced and the Memo-
ry Cache is turned off.
Hard C4E
4)
Power Management for the Intel Atom
processor - Enhanced C4 support.
Disabled Disables this function.
Enabled Enables this function.
The internal CPU voltage is reduced
(can also be 0 V).
Enable C6 Power Management for the Intel Atom
processor - C6 support.
Disabled Disables this function.
