BIOS Setup - 36 -
CPU EIST Function
(Note)
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. AutoletstheBIOSautomaticallycongurethisset-
ting. (Default: Auto)
Bi-Directional PROCHOT
(Note)
Auto  Letsthe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
BCLK/DMI/PEG Frequency(0.1MHz)itembelowtobecongurable.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. (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.

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