VCCSA Voltage
Input voltage for the processor by the external voltage regulator.
VCCSA Load-Line Calibration
VCCSA Load-Line Calibration helps prevent VCCSA voltage droop when the system
is under heavy loading.
VCCSA Over Current Protection
Use this item to configure VCCSA Over Current Protection.
VCCSA Over Voltage Protection
Use this item to configure VCCSA Over Voltage Protection.
VCCSA Under Voltage Protection
Use this item to configure VCCSA Under Current Protection.
VCCSA Over Temperature Protection
Use this item to configure VCCSA Over Temperature Protection.
DRAM Activating Power Supply
Configure the voltage for the DRAM Activating Power Supply.
DRAM Voltage
Use this to configure DRAM Voltage. The default value is [Auto].
VCCIO Voltage
Configure the voltage for the VCCIO.
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.
