Chapter 4: AMI BIOS
4-13
Medium – The processor is running warmer. This is a ‘precautionary’ level and
generally means that there may be factors contributing to this condition, but the CPU
is still within its normal operating state and below the CPU ‘Temperature Tolerance’.
The motherboard fans and CPU will run normally as congured in the BIOS. The
fans may adjust to a faster speed depending on the Fan Speed Control settings.
User intervention: No action is required. However, consider checking the CPU
fans and the chassis ventilation for blockage.
High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Tem-
perature Tolerance’ has been reached (or has been exceeded) and may activate
an overheat alarm:
System Temperature
This feature displays the absolute system temperature (i.e., 90
o
C).
Fan 1 ~ 3 Speed
This feature displays the fan speed readings from fan interfaces
Vcore_CPU, VCC_SA, VCore_GFX, 5VCC, 12V, 3.3VCC, 3VSB, and VBAT
This feature displays the voltage readings for the described components.
ACPIConguration
Use this feature to congure Advanced Conguration and Power Interface (ACPI)
power management settings for your system.
High Precision Event Timers
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.
Suspend Mode
This setting allows you to congure the ACPI (Advanced Conguration and Power
Interface) state for your system when it is in the Suspend mode. The options are
Suspend Disabled, S1 (POS), and S3 (STR).
