nnn nnn This option displays the current processor speed.
nnn nnn This option displays the current Front Side Bus speed. This speed
is selected by the CPU auto-detection logic.
Thermal Management Options:
Dis. En./Dis. When this option is enabled, the CPU temperature is monitored.
Whenever the CPU overheats, the CPU slows down to lower the
temperature.
Dis. En./Dis. When the Thermal Management option and this option are
enabled, a continuous audible alarm is sounded when the
temperature specified in the Overheat Alarm options is reached.
Such an alarm may not be supported by the Operating System.
- Varies Displays the current die (internal) CPU temperature, when
Thermal Management is enabled.
50 10-70 The CPU will be slowed down (Doze mode) when it reaches the
selected Overheat Alarm (°C) temperature.
Full speed (Normal mode) will be resumed when the temperature
comes down to the selected Resume Alarm (°C) temperature.
A minimum of + 4° is automatically ensured for the Overheat
Alarm temperature with reference to the Resume Alarm.
70 30-90 The CPU will be slowed down (Doze mode) when it reaches the
selected Overheat Alarm (°C) temperature.
Full speed (Normal mode) will be resumed when the temperature
comes down to the selected Resume Alarm (°C) temperature.
A minimum of + 4° is automatically ensured for the Overheat
Alarm temperature with reference to the Resume Alarm
- Varies Displays the current case (external) CPU temperature, when
Thermal Management is enabled.
42 10-70
The CPU will be slowed down (Doze mode) when it reaches the
selected Overheat Alarm (°C) temperature.
50 30-90
Full speed (Normal mode) will be resumed when the temperature
comes down to the selected Resume Alarm (°C) temperature.
A minimum of + 4° is automatically ensured for the Overheat
Alarm temperature with reference to the Resume Alarm.
Dis. En./Dis. Saving CMOS memory content into Flash Memory will prevent to
loose CMOS options when battery fails.
En./Dis. This option enables the Watchdog option when the POST is
running.
Dis En./Dis. This option enables Watchdog circuit after the POST sequence
64 to Use this option to setup duration time (in ms) of the Watchdog
262144 timing circuitry.
- Varies Speed sensing device sets this value according to the fan speed.
If no fan is installed or if a fan has no tachymetric capability, this
value will be 0.
- Varies This value is set according to the actual value of Vcpp1 & Vcpp2
- Varies The values of these voltages are each displayed according to the
current value.
