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