2-3 M.I.T.
Whether the system will work stably with the overclock/overvoltage settings you made is dependent 
on	your	 overall	 system	configurations.	 Incorrectly	doing	overclock/overvoltage	 may	result	 in	damage	
to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced 
users only and we recommend you not to alter the default settings to prevent system instability or 
other	 unexpected	 results.	(Inadequately	 altering	the	settings	 may	result	 in...

 This screen provides information on CPU/memory frequencies/parameters.
 `Advanced Frequency Settings 
 &CPU Base Clock
	 Allows	you	to	manually	set	the	CPU	base	clock	in	0.01	MHz	increments.	(Default:	 Auto)
 Important: It is highly recommended that the CPU frequency be set in accordance with the CPU 
specifications.
 &Host/PCIe Clock Frequency (Note)
	 Allows	you	to	manually	 set	the	 host	 clock	 frequency	 (which	controls	 CPU,	PCIe,	 and	memory	 frequencies)

 &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 1)
 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...

 &Profile	DDR	Voltage
 When using a non-XMP memory module or Extreme	 Memory	Profile	(X.M.P.) is set to Disabled, the 
value	is	displayed	 according	 to	your	 memory	 specification.	 When	Extreme	 Memory	Profile	(X.M.P.)	 is	set	
to Profile1 or Profile2, the value is displayed according to the SPD data on the XMP memory.
 &Channel Interleaving
  Enables or disables memory channel interleaving. Enabled allows the system to simultaneously access 
different channels of the memory to increase memory...

 &CPU VRIN Loadline Calibration
	 Allows	you	to	set	 the	 Load-Line	 Calibration	 level	for	the	 CPU	 VRIN.	 The	levels	 are	(from	 highest	 to	lowest):	
Extreme, Turbo, High, Medium, Low, and Standard. Selecting a higher level keeps the CPU VRIN voltage 
more consistent with what is set in BIOS under heavy load. Auto	lets	 the	BIOS	 automatically	 configure
