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. W hen the 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 W idth Modulation Duty Cycle) for maximum cooling. The Full Speed setting is recom-
mended for special system configuration or debugging. Select Performance for the onboard fans
to run at 70% of the Initial PW M Cycle for better system cooling. The Performance setting is recom-
mended for high-power-consum- ing and high-density systems. Select Balanced for the onboard fans
to run at 50% of the Initial PW M Cycle in order to balance the needs between system cooling and
power saving. The Balanced setting is recommended for regular systems with normal hardware
configurations. Select Energy Saving for the onboard fans to run at 30% of the Initial PW M Cycle for
best power efficiency and maximum quietness. The Options are: Full Speed (@100% of PW M
Cycle), Performance (@70% of PW M Cycle), Balanced (@50% of PW M Cycle), and Energy Saving
(@30% of PW M Cycle).
CPU Vcore, AVCC, 3.3Vcc, 12V, V_DIMM, 5V, -12V, 3.3Vsb, and Vbat
This feature displays the voltage readings for the described components.
XACPI Configuration
Use this feature to configure Advanced Configuration and Power Interface (ACPI)
power management settings for your system.
High Performance Event Timer
Select Enabled to activate the High Performance Event Timer (HPET) that produces periodic inter-
rupts 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 Dis-
abled.
USB Device Wakeup
Select Enable to awaken the system via a USB device when the system is in S3 or S4 sleep State.
The options are Enabled and Disabled.
