Gigabyte GA-P67A-UD3R-B3 (REV. 1.1) [36/104] Bclk dmi peg clock control

BIOS Setup - 36 -

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

theBIOSautomaticallycongure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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

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.

Important:ItishighlyrecommendedthattheCPUfrequencybesetinaccordancewiththeCPUspecications.

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)

Prole1  UsesProle1settings.

Prole2

(Note 2)

 UsesProle2settings.

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 rst 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/DMI/PEG

Frequency(0.1MHz) and System Memory Multiplier settings.
