3.12.2 Current System Temp
This shows you the current temperature of system.
3.12.3 Current CPU Temperature
This shows you the current CPU temperature.
3.12.4 Current CPUFAN Speed
This shows you the current CPU fan operating speed.
3.12.5 VCORE, VBAT(V), 5VSB(V)
This shows you the voltage of VCORE, +1.5 V, 3.3 V, +5 V, +12 V, -12 V,
-5 V, VBAT(V), and 5VSB(V).
3.12.6 Shutdown Temperature
This option sets the temperature at which the system will shut down if the
CPU overheats. You can choose a value from 60
°C/140°F, 65°C/149°F,
70
°C/158°F, 75°C/167°F, and Disabled.
3.13 Frequency/Voltage Control

3.13.1 Auto-detect PCI CLK
Use this function to reduce the occurrence of electromagnetic interfer-
ence (EMI). If this option is set to Enabled, BIOS will check for comp-
nents in PCI and DIMM slots, and then turn off clock pulses to empty
slots.
3.13.2 Spread Spectrum
Use this function to tune the PCI clock frequency. Setting this option to
Disabled will limit the clock signal spread, increase the consistency of the
frequency, but increase the EMI. Setting this option to Enabled will
decrease the EMI.
