Chapter 4: BIOS
Hardware Monitor Logic
*Note: The Phoenix BIOS will automatically detect the type of CPU(s)
and hardware monitoring chip used on the motherboard and will display
the Hardware Monitoring Screen accordingly. Your Hardware Monitoring
Screen may look like the one shown on this page, on P. 4-19, or on P. 4-20,
depending on the type of CPU(s) and HW Monitoring chip you are using.
CPU Temperature Threshold
This option allows the user to set a CPU temperature threshold that will activate
the alarm system when the CPU temperature reaches this pre-set temperature
C, 80 C, 85
o
o o o
threshold. The options are 75 C, and 90 C. (*See the note below.)
Highlight this and hit <Enter> to see monitor data for the following items:
CPU1 Temperature
CPU1 Second Core Temperature
CPU2 Temperature
CPU2 Second Core Temperature
System Temperature
Fan1-Fan6 Speeds: If the feature of Auto Fan Control is enabled, the BIOS will
automatically display the status of the fans indicated in this item.
Fan Speed Control Modes
This feature allows the user to decide how the system controls the speeds of the
onboard fans. The CPU temperature and the fan speed are correlative. When
the CPU on-die temperature increases, the fan speed will also increase, and vice
versa. Set this option to "3-pin fan" to allow the fan speed to be controlled by
voltage. Select "Disable" to disable the fan speed control function and allow the
onboard fans to constantly run at full speed (12V). The Options are: 1. Disable,
2. 3-pin (Server), 3. 3-pin (Workstation).
Voltage Monitoring
The following items will be monitored and displayed:
P12V_VR0
P12V_VR1
FSB VTT
PXH-V Vcore
ES2B Vcore
CPU1Vcore
CPU2Vcore
P3V3
*Note: In the Windows OS environment, the Supero Doctor III settings take pre-
cedence over the BIOS settings. When fi rst installed, Supero Doctor III adopts the
temperature threshold settings previously set in the BIOS. Any subsequent changes
to these thresholds must be made within Supero Doctor, since the SD III settings
override the BIOS settings. For the Windows OS to adopt the BIOS temperature
threshold settings, please change the SDIII settings to be the same as those set
in the BIOS.
