SUPER MICRO Computer X7DA3 Hardware Monitor Logic, CPU Temperature Threshold, Voltage Monitoring

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 screen may look differently from the one shown below.

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 70oC, 75oC, 80oC and 85oC.

Highlight this and hit <Enter> to see the status for each of the following 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 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). The Options are: 1. Full Speed@12V (Disable), 2. Optimized Server w/3-pin, 3.Optimized Workstation w/3-pin, 4. Optimized Server w/4-pin, and 5. Optimized Server w/4-pin.

Voltage Monitoring

The following items will be monitored and displayed:

Vcore A/Vcore B/-12V/P1V5/+3.3V/+12V/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.
