[. . . ] of CPU Cores Enabled (Note 1) Allows you to set a current limit for CPU Turbo mode. When the CPU current exceeds the specified current limit, the CPU will automatically reduce the core frequency in order to reduce the current. (Default: Auto) Allows you to select the number of CPU cores to enable in an Intel® multi-core CPU (the number of CPU cores may vary by CPU). (Default: Auto) Allows you to determine whether to enable multi-threading technology when using an Intel® CPU that supports this function. This feature only works for operating systems that support multi-processor mode. (Default: Auto) Enables or disables Intel® CPU Enhanced Halt (C1E) function, a CPU power-saving function in system halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state to decrease power consumption. (Default: Auto) Allows you to determine whether to let the CPU enter C3 mode in system halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state to decrease power consumption. (Default: Auto) Allows you to determine whether to let the CPU enter C6/C7 mode in system halt state. When enabled, the CPU core frequency and voltage will be reduced during system halt state to decrease power consumption. - 21 - `` PC Health Status && Reset Case Open Status Disabled  Keeps or clears the record of previous chassis intrusion status. (Default) Enabled   Clears the record of previous chassis intrusion status and the Case Open field will show "No" at next boot. Displays the detection status of the chassis intrusion detection device attached to the motherboard CI header. If the system chassis cover is removed, this field will show "Yes", otherwise it will show "No". To clear the chassis intrusion status record, set Reset Case Open Status to Enabled, save the settings to the CMOS, and then restart your system. Displays the current system voltages. && Case Open && CPU Vcore/CPU VRIN/DRAM Voltage/+3. 3V/+5V/+12V/CPU VAXG && CPU/System Temperature && CPU/System Fan Speed && CPU Fan Speed Control Displays current CPU/system temperature. Displays current CPU/system fan speeds. Allows you to determine whether to enable the fan speed control function and adjust the fan speed. Normal   Allows the fan to run at different speeds according to the CPU temperature. You can adjust the fan speed with EasyTune based on your system requirements. Manual  Allows you to control the fan speed under the Fan Speed Percentage item. This item is configurable only when CPU Fan Speed Control is set to Manual.
