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)
Bi-Directional PROCHOT
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 adjustable range is
dependent on the CPU being installed. The item is adjustable only if a CPU with unlocked clock ratio is
installed.
QPI Link Speed
Displays the current operating QPI link speed.
System Memory Multiplier (SPD)
Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD
data. (Default: Auto)
Memory Frequency(Mhz)
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 BCLK Frequency(Mhz)
and System Memory Multiplier settings.
(Note) 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.
