Voltage Configuration CPU Vcore Voltage Configure the voltage for the CPU Vcore. CPU Load-Line Calibration CPU Load-Line Calibration helps prevent CPU voltage droop when the system is under heavy load. GT Voltage Configure the voltage for the integrated GPU. GT Load-Line Calibration GT Load-Line Calibration helps prevent GT voltage droop when the system is under heavy load. DRAM Voltage Use this to configure DRAM Voltage. The default value is [Auto]. DRAM Activating Power Supply Configure the voltage for the DRAM Activating Power Supply. PCH +1.0 Voltage Configure the chipset voltage (1.0V). VCCIO Voltage Configure the voltage for the VCCIO. VCCST Voltage Configure the voltage for the VCCST. VCCSA Voltage Configure the voltage for the VCCSA. CPU Internal PLL Voltage Default is 0.900V. Each step is 0.015V. Adding 9- 15 steps will helps CPU PLL to lock internal clock during High frequency under Ln2 cooling. For example: 1.020V - 1.125V 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. CPU Vcore Voltage must higher than CPU Internal PLL Voltage, or your processor will hang. 54 English

Voltage Configuration
CPU Vcore Voltage
Configure the voltage for the CPU Vcore.
CPU Load-Line Calibration
CPU Load-Line Calibration helps prevent CPU voltage droop when the system is
under heavy load.
GT Voltage
Configure the voltage for the integrated GPU.
GT Load-Line Calibration
GT Load-Line Calibration helps prevent GT voltage droop when the system is under
heavy load.
DRAM Voltage
Use this to configure DRAM Voltage. °e default value is [Auto].
DRAM Activating Power Supply
Configure the voltage for the DRAM Activating Power Supply.
PCH +1.0 Voltage
Configure the chipset voltage (1.0V).
VCCIO Voltage
Configure the voltage for the VCCIO.
VCCST Voltage

CPU Internal PLL Voltage
Default is 0.900V. Each step is 0.015V. Adding 9- 15 steps will helps CPU PLL to
lock internal clock during High frequency under Ln2 cooling. For example: 1.020V
- 1.125V will be proper value. But the voltage level will be different on each proces-
sor. User has to find the best value for your own processor. CPU Vcore Voltage must
higher than CPU Internal PLL Voltage, or your processor will hang.
