Turbo Boost Technology

Intel ® Turbo Boost Technology allows processor cores to run faster than the base operating frequency if it’s operating below power, current, and temperature specification limits. Intel ® Turbo Boost Technology is activated when the Operating System (OS) requests the highest processor performance state. The maximum frequency of Intel ® Turbo Boost Technology is dependent on the number of active cores. The amount of time the processor spends in the Intel Turbo Boost 2 Technology state depends on the workload and operating environment. Any of the following can set the upper limit of Intel ® Turbo Boost Technology on a given workload:

• Number of active cores

• Estimated current consumption

• Estimated power consumption

• Processor temperature

When the processor is operating below these limits and the user’s workload demands additional performance, the processor frequency will dynamically increase by 100 MHz on short and regular intervals until the upper limit is met or the maximum possible upside for the number of active cores is reached. For more information about Intel ® Turbo Boost 2 Technology visit the Intel ® website.

Note

Only conga-TS170 module variants that feature the Xeon, Core™ i7 and i5 processors support Intel ® Turbo Boost 2 Technology .

Refer to the power consumption tables in section 2.5 of this document for information about the maximum turbo frequency available for each variant of the conga-TS170.

Adaptive Thermal Monitor and Catastrophic Thermal Protection

Intel ® Xeon, Core™ i7/i5/i3 and Celeron ® processors have a thermal monitor feature that helps to control the processor temperature. The integrated TCC (Thermal Control Circuit) activates if the processor silicon reaches its maximum operating temperature. The activation temperature that the Intel ® Thermal Monitor uses to activate the TCC can be slightly modified via TCC Activation Offset in BIOS setup submenu “CPU submenu”.

The Adaptive Thermal Monitor controls the processor temperature using two methods:

• Adjusting the processor’s operating frequency and core voltage (EIST transitions)

• Modulating (start/stop) the processor’s internal clocks at a duty cycle of 25% on and 75% off
