BIOS setting
Function
Configuration options
Effect
Enabled
The processor speed is regulated by the oper-
ating system.
P-States(IST)
Option for controlling the Intel(R) SpeedStep(TM)
technology. The processor clock speed is in-
creased or decreased according to the number
of calculations that must be made. As a result,
the power consumption depends largely on the
processor load.
Disabled
Disables SpeedStep technology
Enabled
Enables this function
CMP support
This option supports the use of multiple CPUs
(CMP = core multi-processing).
Information:
In order to use ARwin, CMP support
must be switched off to avoid runtime
violations.

Disables temperature monitoring
TM1

TM2
Enables Intel Thermal Mode 2
If the CPU reaches excessive temperatures, the
SpeedStep technology will be enabled.
Thermal mode
1)
Option for configuring temperature monitoring
Information:
To operate the processor within the
specified values, changing the default
setting (TM1 and TM2) is not recom-
mended.
TM1 and TM2
Enables Intel Thermal Mode 1 and 2.
If the CPU reaches excessive temperatures,
TM1 reduces the processor speed by 50% and
TM2 enables Intel SpeedStep technology.
