Internal CPU Power Management
The items in this submenu allow you to set the CPU ratio and features.
Turbo Mode Parameters
CPU Core/Cache Current Limit Max.
This item allows you to configure a higher current limit to prevent a frequency or
power throttling when overclocking. Use the <+> and <-> keys to adjust the value.
Configuration options: [Auto] [0.00] - [255.50]
CPU Graphics Current Limit
This item allows you to configure a higher current limit to prevent a frequency or
power throttling when overclocking. Use the <+> and <-> keys to adjust the value.
Configuration options: [Auto] [0.00] - [255.50]
Long Duration Package Power Limit
An Intel parameter known as “power limit” and specified in Watts. The defualt value is
defined by TDP of the processor. Increasing the value will allow the Turbo ratio to be
maintained for a longer duration under higher current loads. Use the <+> and <-> keys
to adjust the value.
Configuration options: [Auto] [1] - [4095]
Package Power Time Window
An Intel parameter of “power limit 1” and specified in seconds. The applied value
indicates how long the Turbo ratio can be active when TDP is exceeded.
Configuration options: [Auto] [1] - [448]
Short Duration Package Power Limit
An Intel parameter known as “power limit 2” and specified in Watts. It is the second
Intel power limit which provides protection when package power exceeds power limit
1. The default setting is 1.25 times power limit 1. According to Intel, the platform must
support this value for up to 10msec when power consumption exceeds power limit
2. ASUS motherboards are engineered to support this duration for a longer time as
required to facilitate overclocking. Use the <+> and <-> keys to adjust the value.
Configuration options: [Auto] [1] - [4095]
IA AC Load Line
This item allows you to set the AC loadline defined in 1/100 mOhms. Use the <+> and
<-> keys to adjust the value.
Configuration options: [Auto] [0.01] - [62.49]
