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 a more
enhanced performance.
The TPU LEDs (TPU_LED) near the TPU switch light up when you set the TPU switch
to TPU_I mode or TPU_II mode. Refer to section 1.2.8 Onboard LEDs for the exact
location of the TPU LEDs.
If you enable this switch under Windows
®
OS environment, the TPU function will be
activated after the next system bootup.
You may use the 5-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.
