CPU GT Voltage
Configure the voltage for the integrated GPU.
CPU GT Load-Line Calibration
GT Load-Line Calibration helps prevent integrated GPU voltage droop when the
system is under heavy load.
DRAM Voltage
Use this to configure DRAM Voltage. °e default value is [Auto].
VCCIO Voltage
Configure the voltage for the VCCIO.
DRAM Activating Power Supply

PLL Voltage Configuration
CPU Internal PLL Voltage
Default is 0.900V. Each step is 0.0175V. Adding 9~15 steps will help CPU PLL to
lock internal clock during High frequency under Ln2 cooling. For Example: 1.0575V
~ 1.1625V will be proper value. But the voltage level will be different on each
processor. User has to find the best value for your own processor. VCCPLL Voltage
must be at least 150mV higher than the target PLL voltage, or your system will
hang.
