The subitems in this menu allow you to set the CPU ratio and features.
Intel(R) SpeedStep(tm)
Allows the operating system to dynamically adjust the processor voltage and
cores frequency to decrease the average power consumption and decrease
average heat production. Conguration options: [Auto] [Enabled] [Disabled]
Turbo Mode
Allows you to enable your processor cores to run faster than the base
operating frequency when it is below power, current and specication limit.
Conguration options: [Disabled] [Enabled]
Turbo Mode Parameters
The following items appear only when you set the Turbo Mode to [Enabled].
Long Duration Package Power Limit
As know as the power limit 1 in Watts. The default value will be the TDP
(thermal design power). The turbo ratio can be maintained for a duration to
exceed the TDP for the maximum system performance.
Conguration options: [Auto] [1] - [4095]
Package Power Time Window
As know as the power limit 1 in seconds. The value indicates the
maintained duration for the turbo ratio to exceed TDP (thermal design
power).
Conguration options: [Auto] [1] - [127]
Short Duration Package Power Limit
Also know as the power limit 2 in Watts. It is the second power limit to
provide a rapid protection when the package power exceed power limit
1. The default setting is 1.25 times the power limit 1. According to Intel,
the platform must be capable of supporting the duration for up to 10 msec
when the turbo ratio exceeds the power limit 2.
Conguration options: [Auto] [1] - [4095]
IA AC Load Line
This item allows you to set the AC loadline dened in 1/100 mOhms. Use the

Conguration options: [Auto] [0.01] - [62.49]
3.3.9 CPU Core/Cache Current Limit Max.
This item allows you to congure a higher current limit to prevent a frequency or power
throttling when overclocking.
Conguration options: [Auto] [0.00] - [255.50]
