CPU Power Management Configuration
Intel SpeedStep Technology
Intel SpeedStep technology is Intel’s new power saving technology. Pro- cessor can switch between multiple frequency and voltage points to en- able power savings. The default value is [Enabled]. Configuration options: [Enabled] and [Disabled]. If you install Windows® VistaTM / 7 and want to enable this function, please set this item to [Enabled]. This item will be hid- den if the current CPU does not support Intel SpeedStep technology.
Please note that enabling this function may reduce CPU voltage and lead to system stability or compatibility issue with some power supplies. Please set this item to [Disable] if above issue occurs.
Intel Turbo Mode Technology
Use this item to enable or disable Intel Turbo Boost Mode Technology. Turbo Boost Mode allows processor cores to run faster than marked fre- quency in specific conditions. The default value is [Enabled].
CPU Thermal Throttling
You may select [Enabled] to enable CPU internal thermal control mechanism to keep the CPU from overheated.
Enhance Halt State (C1E)
All processors support the Halt State (C1). The C1 state is supported through the native processor instructions HLT and MWAIT and requires no hardware support from the chipset. In the C1 power state, the processor maintains the context of the system caches.
CPU C3 State Support
Use this to enable or disable CPU C3 (ACPI C2) report to OS.
CPU C6 State Support
Use this to enable or disable CPU C6 (ACPI C3) report to OS.
Package C State Support
Selected option will program into C State package limit register. The default value is [Disabled].
Internal PLL Overvoltage
Use this item to enable/disable CPU Internal PLL Overvoltage Function.
OS
Use this item to enable/disable
Turbo Boost Power Limit
Use this item to adjust Turbo Boost power limit. Configuration options: [Auto] and [Manual]. The default value is [Auto].
Core Current Limit
Use this item to add voltage when CPU is in Turbo mode.
