TPU (Turbo Processing Unit)
TPU allows you to manually adjust the CPU frequency, CPU cache, core frequencies, DRAM
frequency, and related voltages for an enhanced system stability and a performance boost.
Refer to the CPU documentation before adjusting CPU voltage settings. Setting a high
voltage may damage the CPU permanently, and setting a low voltage may lead to an
unstable system.
For system stability, the TPU settings are not saved in the BIOS and are not loaded during
system bootup. Save your overclocking settings as a TPU prole and manually load this
prole after system bootup.

• When you enable Congured Max CPU Power for advanced energy saving condition,
the CPU frequency may display 800 MHz in the Windows® OS information of your
computer. However, the true CPU frequency varies depending on the wattage that you
manually set. You can adjust the CPU wattage from the lowest base on your preferred
default value.
• Congured Max CPU Power may decrease the total power delivery to the CPU and
affects the CPU performance under system heavy load. To restore your system to its
default settings, reboot your computer.

Enables spread spectrum to enhance system stability.
CPU Load-line Calibration
It allows you to adjust the voltage range to control the CPU Load-line. Adjust to a
high value for system performance or to a low value for power efciency.
CPU Current Capability
CPU Current Capability provides a wider total power range for overclocking.
A higher value brings a wider total power range and extends the overclocking
frequency range simultaneously.
CPU Power Thermal Control
A higher temperature brings a wider CPU power thermal range and extends the
overclocking tolerance to enlarge the overclocking potential.
CPU Power Duty Control
CPU Power Duty Control adjusts the current of every VRM phase and the thermal
conditions of every phase component.
