Hyper-Threading Technology
&
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.
Auto lets the BIOS automatically configure this setting. (Default: Auto)
CPU Enhanced Halt (C1E)
&
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. Auto lets the BIOS automatically configure this setting. (Default: Auto)
C3/C6 State Support
&
Allows you to determine whether to let the CPU enter C3/C6 mode in system halt state. When enabled, the
CPU core frequency and voltage will be reduced during system halt state to decrease power consumption.
The C3/C6 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
& (Note 1)
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 setting.
(Default: Auto)
Extreme Memory Profile (X.M.P.)
&
Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance
when enabled.
Disabled Disables this function. (Default)

Profile1 Uses Profile 1 settings.

Profile2 Uses Profile 2 settings.
(Note 2)

System Memory Multiplier
&
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 System Memory Multiplier
settings.
