Turbo Mode [Enabled] It automatically allows processors cores to run faster than the base operating frequency if it's operating below power, current, and temperature specification limit. Configuration options: [Disabled] [Enabled] Turbo Mode Parameters Long Duration Power Limit [Auto] This item is Power Limit 1 in Watts. Default setting of this item is TDP (130W). For Sandy Bridge-E, Turbo Ratio can be kept a time duration exceeding TDP for maximum performance. Any value under 255 can be programmed. Use the and keys to adjust the value. Long Duration Maintained [Auto] This item is Power Limit 1 Time in second. The value can vary from 1 to 32, which indicates that 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 item is Power Limit 2 value in Watts. It 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. Intel recommends that the 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] Maximum additional voltage can be 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 Core Current Limit, unit in 0.125A. Use the and keys to adjust the value. CPU VCORE Voltage [Offset Mode] This adjusts the power supply for the processor cores and cache to help core frequency overclocking. [Manual Mode] Allows you to set a fixed CPU VCORE 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 VCORE voltage. The values range from 0.800V to 1.700V with a 0.005V interval. Chapter 3 ASUS P9X79 WS 3-25

operating below power, current, and temperature speciﬁcation limit.

Conﬁguration options: [Disabled] [Enabled]

Turbo Mode Parameters

Long Duration Power Limit [Auto]

This item is Power Limit 1 in Watts. Default setting of this item is TDP (130W). For

Sandy Bridge-E, Turbo Ratio can be kept a time duration exceeding TDP for maximum

performance. Any value under 255 can be programmed. Use the <+> and <-> keys to

adjust the value.

Long Duration Maintained [Auto]

This item is Power Limit 1 Time in second. The value can vary from 1 to 32, which

indicates that 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 item is Power Limit 2 value in Watts. It 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. Intel recommends that the 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.

Maximum additional voltage can be 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 Core Current Limit, unit in 0.125A. Use the <+> and

<-> keys to adjust the value.

CPU VCORE Voltage [Offset Mode]

This adjusts the power supply for the processor cores and cache to help core frequency

overclocking.

[Manual Mode]

Allows you to set a ﬁxed CPU VCORE 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 VCORE voltage. The values range from 0.800V to

1.700V with a 0.005V interval.
