Thermal Slow Clock Ratio [50-56.25%]

This field determines the duty cycle of the STPCLK# signal when the THRM# pin is asserted low. In other words, this feature sets the percentage by which the CPU slows down when the CPU is overheated. NOTE: To access this field, the System Thermal field must be set to [Monitor].

Power Button Function [On/Off]

When set to [On/Off], the ATX switch can be used as a normal system power-off button when pressed for less than 4 seconds. [Suspend] allows the button to have a dual function where pressing less than 4 seconds will place the system in sleep mode.
