CPU Power Management
The sub-items in this menu allow you to set the CPU ratio and features.
CPU Ratio [Auto]
Allows you to manually adjust the maximum non-turbo CPU ratio. Use <+> and <-> keys to
adjust the value. The valid value ranges vary according to your CPU model.
Enhanced Intel SpeedStep Technology [Enabled]
Allows you to enable or disable the Enhanced Intel
®
SpeedStep Technology (EIST).
[Disabled] Disables this function.
[Enabled] The operating system dynamically adjusts the processor voltage and
core frequency which may result in decreased average consumption and
decreased average heat production.
Turbo Mode [Enabled]
This item appears only when you set the previous item to [Enabled].
[Enabled] Allows processor cores to run faster than marked frequency in specic
conditions.
[Disabled] Disables this function.
The following three items appear only when you set the Turbo Mode item to [Enabled].
Long duration power limit [Auto]
The default setting of this item will be TDP (65W or 95W for different CPUs). For
Sandy Bridge, Turbo Ratio can be kept a time duration exceed TDP for maximum
performance. Any under 255 can be programmed. Use the <+> and <-> keys to adjust
the value.
Long duration maintained [Auto]
This value can vary from 1 to 32, which indicates the time window for Turbo Ratio over
TDP should be maintained. Use the <+> and <-> keys to adjust the value.
Short duration power limit [Auto]
This is the second power limit to provide rapid protection when package power
exceeds Power Limit 1. Default setting is 1.25 times Power Limit 1. For Intel
recommend, platform must be capable of supporting over Power Limit 2 for up to 10
msec. ASUS board can support over Power Limit 2 for a long duration. Use the <+>
and <-> keys to adjust the value.
Primary Plane Current Limit [Auto]
Maximum instantaneous current allowed at any given time for CPU cores. The value is
represented in 1/8 A (0.125A) increment. Use the <+> and <-> keys to adjust the value.
Secondary Plane Current Limit [Auto]
Maximum instantaneous current allowed at any given time for internal graphics cores.
The value is represented in 1/8 A (0.125A) increment. Use the <+> and <-> keys to
adjust the value.
