BIOS Setup - 40 -
C3/C6 State Support
(Note 1)
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 con-
sumption. The C3/C6 state is a more enhanced power-saving state than C1. Auto lets the BIOS auto-
maticallycongurethissetting.(Default:Auto)
CPU Thermal Monitor
(Note 1)
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

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congurethisset-
ting. (Default: Auto)
Bi-Directional PROCHOT
(Note 1)
Auto  LetsBIOSautomaticallycongure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.
>>>>> Standard Clock Control
BCLK/DMI/PEG Clock Control
Enables or disables the control of CPU base clock and DMI/PCIe bus frequency. Enabled will allow the

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. (Default: Disabled)
BCLK/DMI/PEG Frequency(0.1MHz)
Allows you to manually set the CPU base clock and DMI/PCIe bus frequency. The adjustable range is
from800MHzto2000MHz.ThisitemiscongurableonlywhentheBCLK/DMI/PEG Clock Control op-
tion is enabled.

Extreme Memory Prole (X.M.P.)
(Note 2)
Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance
when enabled.
Disabled Disables this function. (Default)

System Memory Multiplier (SPD)
Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD
data. (Default: Auto)
