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
o
threshold. The hardcode default setting is 75 C. (See the note below.)
Temperature Monitoring (*Available if supported by the CPU)
Highlight this and hit <Enter> to see monitor data for the following PECI (Platform
Environment Control Interface) items:
CPU1 Temperature/CPU1 Second Core/CPU2 Temperature/CPU2 Second
Core
PECI Agent 1 Temperature/PECI Agent 2 Temperature
PECI Agent 3 Temperature/PECI Agent 4 Temperature
System Temperature
Fan1-Fan8 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.
If the option is set to "3-pin fan", the fan speed is controlled by voltage. If the op-
tion is set to "4-pin", the fan speed will be controlled by Pulse Width Modulation
(PWM). Select "3-pin" if your chassis came with 3-pin fan headers. Select "4-pin"
if your chassis came with 4-pin fan headers. Select "Workstation" if your system is
used as a Workstation. Select "Server" if your system is used as a Server. Select
"Disable" to disable the fan speed control function to allow the onboard fans to
constantly run at full speed (12V). The Options are: 1. Disable, 2. 3-pin (Server),
3. 3-pin (Workstation), 4. 4-pin (Server) and 5. 4-pin (Workstation).
Voltage Monitoring
The following items will be monitored and displayed:
Vcore A/Vcore B/-12V/+12V/P1V5/+3.3V/5Vsb/5VDD/P_VTT/Vbat
*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.
