One embodiment of the present invention provides a system that facilitates
temporarily increasing the operating frequency of an electronic circuit,
such as a computer system, beyond a maximum sustainable operating
frequency. Upon receiving a request to operate at a higher frequency, the
system determines the thermal energy level of a cooling system for the
circuit. If the thermal energy level is below a threshold level for the
thermal capacity of the cooling system, the system increases the
operating frequency of the circuit to a frequency that is greater than
the maximum sustainable operating frequency for a period of limited
duration. This period of limited duration is short enough to ensure that
a temperature increase, caused by increasing the operating frequency,
does not raise the operating temperature of the circuit above a maximum
operating temperature.
