[Enabled] Locks the CFG lock bit.
[Disabled] Un-locks the CFG lock bit.
fEIST [Enabled]
Enables or disables the Enhanced Intel
®
SpeedStep Technology. This item will
appear when OC Explore Mode is set to Normal.
[Enabled] Enables the EIST to adjust CPU voltage and core frequency
dynamically. It can decrease average power consumption and
average heat production.
[Disabled] Disables EIST.
fIntel Turbo Boost [Enabled]
Enables or disables the Intel
®
Turbo Boost. This item is for Normal mode and
appears when a CPU that support Turbo Boost is installed.
[Enabled] Enables this function to boost CPU performance automatically over
specification when system request the highest performance state.
[Disabled] Disables this function.
fLong Duration Power Limit (W) [Auto]
Sets the long duration TDP power limit for CPU in Turbo Boost mode.
fLong Duration Maintained (s) [Auto]
Sets the maintaining time for Long duration power Limit(W).
fShort Duration Power Limit (W) [Auto]
Sets the short duration TDP power limit for CPU in Turbo Boost mode.
fCPU Current Limit (A) [Auto]
Sets maximum current limit of CPU package in Turbo Boost mode. When the
current is over the specified value, the CPU will automatically reduce the core
frequency for reducing the current.
fFCLK Frequency [Auto]
Sets FCLK frequency. Lower FCLK frequency may help you to set higher base clock
frequency.
fDMI Link Speed [Auto]
Sets DMI speed.
fSW Guard Extensions (SGX) [Software Control]
Enables or disables Intel SGX.
fIntel Speed Shift Technology [Auto]
