(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.
 PWM Frequency Control
  Allows you to alter the PWM frequency. Auto	lets	the	BIOS	automatically	configure	this	setting.	(Default:		
 Auto)
 CPU Over Current Protection 
  Allows you to set the maximum over-current value for CPU over-current protection. The adjustable range  
  is from +60% to -10%. Auto	lets	the	BIOS	automatically	configure	this	setting.	(Default:	 Auto)
 Internal CPU PLL Overvoltage 
 Enabled allows CPU PLL voltage to operate at a higher value.  Disabled allows CPU PLL voltage to  
 operate at default value. Auto	lets	the	BIOS	automatically	configure	this	setting.	(Default:	 Auto)
 Real-Time Ratio Changes in OS (Note)
 Enabled allows you to make real-time changes to the CPU clock ratio in your operating system. The  
  Intel Turbo Boost technology and associated items below will become unavailable. Set this item to Dis- 
 abled if	you	want	to	manually 	configure	CPU	Turbo	ratios	in	BIOS	setup.	Auto lets the BIOS automati- 
	 cally	configure	this	setting.	(Default:	 Auto)
 Intel(R) Turbo Boost Tech. (Note)
  Allows you to determine whether to enable the Intel CPU Turbo Boost technology. Auto lets the BIOS  
	 automatically	configure	this	setting.	(Default:	 Auto)
 Turbo Ratio (1-Core)/(2-Core)/(3-Core)/(4-Core) (Note)
  Allows you to set the CPU Turbo ratios for different number of active cores. Auto sets the CPU Turbo  
	 ratios	according	to	the	CPU	specifications.	(Default: Auto)
 Turbo Power Limit (Watts)
  Allows you to set a power limit for CPU Turbo mode. When the CPU power consumption exceeds the  
	 specified	power	limit,	the	CPU	will	automatically	reduce	the	core	frequency	in	order	 to	reduce	the	power.
 Auto	sets	the	power	limit	according	to	the	CPU	specifications.	(Default: Auto)
 Core Current Limit (Amps)
	 Allows	you	to	set	a	current	limit	for	CPU	 Turbo	mode.	When	the	CPU	current	exceeds	the	specified	cur-	
 rent limit, the CPU will automatically reduce the core frequency in order to reduce the current.  Auto sets  
	 the	current	limit	according	to	the	CPU	specifications.	(Default: Auto)
 CPU Cores Enabled (Note)
 Allows you to determine whether to enable all CPU cores.
 All    Enables all CPU cores. (Default)
 1    Enables only one CPU core.
 2    Enables only two CPU cores.
 3    Enables only three CPU cores.
 CPU Multi-Threading (Note)
 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. 
(Default: Enabled)
 CPU Enhanced Halt (C1E) (Note)
 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 de -
crease power consumption.  Auto
	lets	the	BIOS	automatically	configure	this	setting.	(Default:	Disabled) 
						

							BIOS Setup- 42 -
 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	configure	this	setting.	(Default:	Disabled)
 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	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	set-
ting. (Default: Disabled)
  Bi-Directional PROCHOT (Note 1)
 Auto	 	 Lets 	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.
>>>>>   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	 configurable.	 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	configurable	 only	if	the	BCLK/DMI/PEG Clock Control option is 
enabled.
 Important:	It	is	highly	recommended	that	the	CPU	frequency	be	set	in	accordance	with	the	CPU	specifications.
  Extreme Memory Profile (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)
 Profile1	 	 Uses	Profile	1	settings.
 Profile2 (Note 2)	 Uses	Profile	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)
(Note 1)  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.
(Note 2) This item is present only if you install a memory module that supports this feature.

and Channel B Timing Settings
	items	to	be	configurable.	Options	are:	 Auto	(default),	Quick,	Expert.
 Profile DDR Voltage
  When  using  a  non-XMP  memory  module  or Extreme  Memory  Profile  (X.M.P.)  is  set  to  Disabled,  this 
item  will  display  as  1.5V.  When Extreme  Memory  Profile  (X.M.P.)   is  set  to Profile1  or  Profile2,  this 
item will display the value based on the SPD data on the XMP memory.
