4. TPU switch
With its two-level adjustment functions, the TPU allows you to automatically adjusts the
CPU ratio and clock speed for an optimal system performance.
• Enable this switch when the system is powered off.
• When the TPU switch is set to Enabled (TPU_I: CPU Ratio Boost), the system
automatically adjusts the CPU ratio for an enhanced performance.
• When the TPU switch is set to Enabled (TPU_II: CPU BCLK and Ratio Boost), the
system automatically adjusts the base clock rate (BLCK) and the CPU ratio for
enhanced performance.
• The TPU LED (TPU_LED) near the TPU switch lights up when the TPU switch is
enabled. Refer to section 1.2.8 Onboard LEDs for the exact location of the TPU LED.
• If you enable this switch under Windows
®
OS environment, the TPU function will be
activated after the next system bootup.
• You may use the 4-Way Optimization and TPU feature in the AI Suite 3 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.
