(Note 1) This item is present only if you install a CPU that supports this feature. For more information about
Intel CPUs' unique features, please visit Intel's website.
(Note 2) This item appears only if you install a memory module that supports this feature.
C3/C6/C7 State Support
Allows you to determine whether to let the CPU enter C3/C6/C7 mode in system halt state. When en-
abled, the CPU core frequency and voltage will be reduced during system halt state to decrease power
consumption. The C3/C6/C7 state is a more enhanced power-saving state than C1. Auto lets the BIOS
automatically configure this setting. (Default: Auto)
CPU Thermal Monitor
Enables or disables Intel CPU Thermal Monitor function, a CPU overheating protection function. When
enabled, the CPU core frequency and voltage will be reduced when the CPU is overheated. Auto lets
the BIOS automatically configure this setting. (Default: Auto)
CPU EIST Function
Enables or disables Enhanced Intel SpeedStep 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. Auto lets the BIOS automatically configure this set-
ting. (Default: Auto)
Lets the BIOS automatically configure this setting. (Default)
Enabled When the CPU or chipset detects that an overheating is occurring, PROCHOT signals will
be emitted to lower CPU performance to decrease heat production.
Disabled Only allows the CPU to detect whether an overheating is occurring to emit PROCHOT signals.
QPI Clock Ratio
Allows you to set the QPI clock ratio. Options are: Auto (default), x12~x44. The item is adjustable only if a
CPU with unlocked clock ratio is installed. The adjustable range is dependent on the CPU being installed.
QPI Link Speed
Displays the current operating QPI link speed.
>>>>> Standard Clock Control
Base Clock(BCLK) Control
Enables or disables the control of CPU base clock. Enabled will allow the BCLK Frequency(Mhz) item
below to be configurable. Note: If your system fails to boot after overclocking, please wait for 20 seconds
to allow for automated system reboot, or clear the CMOS values to reset the board to default values.
Allows you to manually set the CPU base clock. The adjustable range is from 100 MHz to 600 MHz. This
item is configurable only if the Base Clock(BCLK) Control option is enabled.
Important: It is highly recommended that the CPU frequency be set in accordance with the CPU specifi-
Extreme Memory Profile (X.M.P.)
Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance
Disables this function. (Default)
Uses Profile 1 settings.
Uses Profile 2 settings.
