2-20 Chapter 2: BIOS information
Advanced Clock Calibration [Disabled]
Adjusts the processor’s overclocking capability. Select [Auto] to allow the BIOS automatically
adjusts this function. Select [All Cores] to congure all the processor cores as a whole.
Select [Per Core] to congure each processor core separately. Conguration options:
[Disabled] [Auto] [All Cores] [Per Core]
The following items only appear when you set Advanced Clock Calibration to [Auto],
[All Cores], or [Per Core].
Unleashing Mode [Disabled]
Enable the Unleashing Mode to get full computing power of the processor. However,
this might make your system unstable depending on your processor’s overclocking
capability. Conguration options: [Enabled] [Disabled]
Active CPU Cores [Auto]
Allows you to manually turn ON/OFF a process core. Conguration options: [Auto]
[Manual]
2nd / 3rd / 4th Core [On]
These items only appear when you set Active CPU Cores to [Manual].
Conguration options: [On] [Off]
Value (All Cores) [-2%]
This item only appears when you set Advanced Clock Calibration to [All Cores]. It
allows you to set the overclocking percentage for all the processor cores as a whole.
Conguration options: [0%] [+2%] [+4%] [+6%] [+8%] [+10%] [+12%] [-2%] [-4%]
[-6%] [-8%] [-10%] [-12%]
Value (Core 0) / (Core 1) / (Core 2) / (Core 3) [-2%]
These items only appear when you set Advanced Clock Calibration to [Per Core]
and allow you to set the overclocking percentage for each process core separately.
Conguration options: [0%] [+2%] [+4%] [+6%] [+8%] [+10%] [+12%] [-2%] [-4%]
[-6%] [-8%] [-10%] [-12%]
