XHardware 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. 4-20, or on P. 4-21. It depends on the type of CPU(s) and HW

Monitoring chip you are using.

CPU Temperature Threshold

This option displays the CPU temperature threshold that will activate the alarm

system when the CPU temperature reaches this pre-set 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 display information on 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-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.

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 chas-

sis 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 and allow the onboard fans to constantly run

at full speed (12V). Select 4-pin Quiet (or Super Quiet) to lower the fan speed and

noise. The Options are: 1. Disable, 2. 3-pin (Server), 3. 3-pin (Workstation), 4. 4-pin

(Server), 5. 4-pin (Workstation), 6. 4-pin (Quiet) and 7. 4-pin (Super Quiet).

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 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.
