1-20 Chapter 1: Product introduction
2. Turbo Key II switch
This switch allows you to auto-tune your CPU to enhance the system performance.
• The LED near the Turbo Key II switch lights when the switch setting is turned to Enable.
• If you clear the CMOS or load the BIOS setup defaults, the related overclocking items in
the BIOS menu follow the current setting of the Turbo Key II switch.
• If you change the switch setting to Enable under the OS environment, the Turbo Key II
function will be activated after the next system bootup.
• You may use the TurboV Auto Tuning, overclock in the BIOS setup program, and enable
the Turbo Key II function at the same time. However, the system will use the last setting
you have made.
For ensuring the system performance, turn the switch setting to Enable when the system
is powered off.
