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.

[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]

[Disabled]

Disables this function.

[Enabled]

Allows processor cores to run faster than marked frequency in specific

 

condition.

The following items appear only when you set the Turbo Mode items to [Enabled].

Turbo Mode Parameters

Long Duration Power Limit [Auto]

The default setting of this item will be TDP (130W). For Sandy Bridge-E, Turbo Ratio can be kept a time duration exceed TDP for maximum performance. Any value 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.

Additional Turbo Voltage [Auto]

This item allows user to set the maximum additional voltage applied to the CPU when Turbo Boost is engaged. Use the <+> and <-> keys to adjust the value.

CPU Core Current Limit [Auto]

This item allows user to enter CPU Current Limit, unit in 0.125A. Use the <+> and <-> keys to adjust the value.

CPU VCORE Voltage [Offset Mode]

[Manual Mode]

Allows you to set a fixed CPU voltage.

[Offset Mode]

Allows you to set the Offset voltage.

CPU VCORE Manual Voltage [Auto]

This item appears only when you set the CPU VCORE Voltage item to [Manual Mode] and allows you to set a fixed CPU voltage. The values range from 0.800V to 1.700V with a 0.005V interval.
