Hardware Monitor Logic
Note
: 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. 4-18, or on P. 4-19, 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
threshold. The options are 70
o
C, 75
o
C,
80
o
C
and 85
o
C. (See the note below.)
Highlight this and hit <Enter> to see the status for each of the following items:
CPU1 Temperature/CPU2 Temperature/System Temperature
Fan1-Fan5 Speeds
: If the feature of Auto Fan Control is enabled, 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
option 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 the full speed (12V). The Options are:
1. Disable
, 2. Optimized
for Servers with 3-pin, 3. Optimized for Workstations with 3-pin, 4. Optimized for
Servers with 4-pin, and 5. Optimized for Workstations with 4-pin.
Voltage Monitoring
The following items will be monitored and displayed:
Vcore A/Vcore B
1.8V
3.3V Standby/3.3V/5V
12V
Vbat
Note:
In the Windows OS environment, the Supero Doctor III settings take prece-
dence 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.
