[. . . ] (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. (Default: Auto) Enables or disables Intel® Thermal Monitor function, a CPU overheating protection function. When enabled, the CPU core frequency and voltage will be reduced when the CPU is overheated. (Default: Auto) && Core Current Limit (Amps) && No. of CPU Cores Enabled (Note) && Hyper-Threading Technology (Note) && CPU Enhanced Halt (C1E) (Note) && C3 State Support (Note) && C6/C7 State Support (Note) && CPU Thermal Monitor (Note) (Note) This item is present only when you install a CPU that supports this feature. For more information about Intel® CPUs' unique features, please visit Intel's website. - 21 - && CPU EIST Function (Note 1) Enables or disables Enhanced Intel® Speed Step Technology (EIST). Depending on CPU loading, Intel EIST technology can dynamically and effectively lower the CPU voltage and core frequency to decrease average power consumption and heat production. (Default: Auto) && Extreme Memory Profile (X. M. P. ) (Note 2) && System Memory Multiplier Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when enabled. (Default: Auto) The first memory frequency value is the normal operating frequency of the memory being used; the second is the memory frequency that is automatically adjusted according to the System Memory Multiplier settings. && Memory Frequency (MHz) `` Advanced Memory Settings && Extreme Memory Profile (X. M. P. ) (Note 2), System Memory Multiplier, Memory Frequency(MHz) && Memory Boot Mode (Note 2) The settings above are synchronous to those under the same items on the Advanced Frequency Settings menu. Options are: Disabled (default), 60oC/140oF, 70oC/158oF, 80oC/176oF, 90oC/194oF. Allows the system to emit warning sound if the fan is not connected or fails. (Default: Disabled) - 23 - && CPU Fan Control Mode && CPU Fan Speed Control Specifies how to control CPU fan speed. Auto   Lets the BIOS automatically detect the type of CPU fan installed and sets the optimal CPU fan control mode. Note: The Voltage mode can be set for a 3-pin CPU fan or a 4-pin CPU fan. However, for a 4-pin CPU fan that is not designed following Intel PWM fan specifications, selecting PWM mode may not effectively reduce the fan speed. 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 System Information Viewer 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. Allows you to determine whether to enable the fan speed control function and adjust the fan speed.
