[Values 12~32] [Values 33~57] Presets Enhanced Intel SpeedStep Technology and Turbo Mode to [Disabled] but can be adjusted. Resumes full adjustment for Turbo Mode Parameters but disallows configuration for Turbo Mode. Chapter 3 3-24 Enhanced Intel SpeedStep Technology® [Enabled] Enhanced Intel SpeedStep Technology® allows the system operation system to dynamically adjust processor voltage and cores frequency, which can result in decreased average power consumption and decreased average heat production. Configuration options: [Disabled] [Enabled] Chapter 3: BIOS setup 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. For Sandy Bridge-E, Turbo Ratio can be kept a time duration exceeding TDP for maximum performance. 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. 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. Intel recommends that the platform must be capable of supporting over Power Limit 2 for up to 10 msec. Additional Turbo Voltage [Auto] Maximum additional voltage can be applied to the CPU when Turbo Boost is engaged. 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.
