(Note)	 This	item	is	present	 only	when	 you	install	 a	CPU 	that	 supports	 this	feature.	 For	more	 information	 about	
Intel® CPUs' unique features, please visit Intel's website.
 &Turbo Ratio (1-Core Active~4-Core Active) (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	 current	
limit, the CPU will automatically reduce the core frequency in order to reduce the current. Auto sets the 
power	limit	according	to	the	CPU	specifications.	(Default:	 Auto)
 &No. of CPU Cores Enabled (Note)
 Allows you to select the number of CPU cores to enable in an Intel®	multi-core	CPU	(the	number	of	CPU	
cores	may	vary	by	CPU).	Auto	lets	the	BIOS	automatically	configure	this	setting.	(Default:	 Auto)
 &Hyper-Threading Technology (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. 
Auto	lets	the	BIOS	automatically	configure	this	setting.	(Default:	 Auto)
 &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 red\
uced during system halt state 
to decrease power consumption. Auto	lets	the	BIOS	automatically	configure	this	setting.	(Default:	 Auto)
 &C3 State Support (Note)
 Allows you to determine whether to let the CPU enter C3 mode in system halt state. When enabled, the 
CPU core frequency and voltage will be reduced during system halt state to d\
ecrease power consumption. 
The C3 state is a more enhanced power-saving state than C1. Auto	lets	 the	BIOS	 automatically	 configure	
this	setting.	(Default:	 Auto)
 &C6/C7 State Support (Note)
 Allows you to determine whether to let the CPU enter C6/C7 mode in system halt state. When enabled, the 
CPU core frequency and voltage will be reduced during system halt state to d\
ecrease power consumption. 
The C6/C7 state is a more enhanced power-saving state than C3. Auto	lets	 the	BIOS	 automatically 	configure 	
this	setting.	(Default:	 Auto)
 &CPU Thermal Monitor (Note)
 Enables or disables Intel® Thermal Monitor function, a CPU overheating protection function. When en\
abled, 
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)
 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	 configure	this	setting.	
(Default:	 Auto)
