CPU on-die temperature increases, the fan speed will also increase for effective

system cooling. Select Full Speed to allow the onboard fans to run at full speed (of

100% Pulse Width Modulation Duty Cycle) for maximum cooling. The Full Speed

setting is recommended for special system conguration or debugging. Select

Performance for the onboard fans to run at 70% of the Initial PWM Cycle for better

system cooling. The Performance setting is recommended for high-power-consum-

ing and high-density systems. Select Balanced for the onboard fans to run at 50%

of the Initial PWM Cycle in order to balance the needs between system cooling

and power saving. The Balanced setting is recommended for regular systems with

normalhardwarecongurations.SelectEnergySavingfortheonboardfanstorun

at30%oftheInitialPWMCycleforbestpowerefciencyandmaximumquietness.

The Options are: Full Speed/FS (@100% of PWM Cycle), Performance/PF (@70%

of PWM Cycle), Balanced/BL (@50% of PWM Cycle), and Energy Saving/ES

(@30% of PWM Cycle).

Voltage Reading

This feature displays the current voltage detected of the various components in

the system:

Vcore, VDIMM, 5V, 12V, -12V, 3.3Vcc, 3.3VSB, VBAT, Vtt

power management settings for your system.

High Performance Event Timer

Select Enabled to activate the High Performance Event Timer (HPET) that produces

periodic interrupts at a much higher frequency than a Real-time Clock (RTC) does in

synchronizing multimedia streams, providing smooth playback and reducing the de-

pendency on other timestamp calculation devices, such as an x86 RDTSC Instruc-

tion embedded in the CPU. The High Performance Event Timer is used to replace

the 8254 Programmable Interval Timer. The options are Enabled and Disabled.

ACPI Aware O/S

Enable ACPI support if it is supported by the OS to control ACPI through the Operat-

ing System. Otherwise, disable this feature. The options are Yes and No.

AMI OEMB Table

This enables the OEMB table support. The options are Enabled and Disabled.
