Thermal Management
Once a target frequency/bus ratio is resolved, the processor core will transition to the
new target automatically.
new target automatically.
• On an upward operating point transition, the voltage transition precedes the
frequency transition.
• On a downward transition, the frequency transition precedes the voltage transition.
When transitioning to a target core operating voltage, a new VID code to the voltage
regulator is issued. The voltage regulator must support dynamic VID steps to support
this method.
regulator is issued. The voltage regulator must support dynamic VID steps to support
this method.
During the voltage change:
• It will be necessary to transition through multiple VID steps to reach the target
operating voltage.
• Each step is 5 mV for Intel MVP-7.0 compliant VRs.
• The processor continues to execute instructions. However, the processor will halt
• The processor continues to execute instructions. However, the processor will halt
instruction execution for frequency transitions.
If a processor load-based Enhanced Intel SpeedStep Technology/P-state transition
(through MSR write) is initiated while the Adaptive Thermal Monitor is active, there are
two possible outcomes:
(through MSR write) is initiated while the Adaptive Thermal Monitor is active, there are
two possible outcomes:
• If the P-state target frequency is higher than the processor core optimized target
frequency, the p-state transition will be deferred until the thermal event has been
completed.
completed.
• If the P-state target frequency is lower than the processor core optimized target
frequency, the processor will transition to the P-state operating point.
