shut down the system and unplug the power cable before removing or plugging in any
motherboard component. The illustration below shows the location of the onboard LED.

2. TPU (GPU Boost) switch
Turning this switch to Enable will automatically optimize the system for fast, yet stable
clock speeds.
• For ensuring the system performance, turn the switch setting to Enable
when the system is powered off.
• When the TPU switch is set to Enable, it can be used as GPU Boost
switch.
• The TPU LED (ELED 730) near the TPU switch lights when the switch setting
is turned to Enable. Refer to section 1.12 Onboard LEDs for the exact location
of the TPU LED.
• If you change the switch setting to Enable under the OS environment, the
TPU function will be activated after the next system bootup.
• You may use the TurboV and Auto Tuning feature in the TurboV EVO
application, adjust the BIOS setup program, or enable the TPU switch at the
same time. However, the system will use the last setting you have made.
