Processor Features
8.2.1
Intel
®
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.
8.2.2
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
