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.
Save User Default
Type a profile name and press enter to save your settings as user default.
Load User Default
Load previously saved user defaults.
Save User UEFI Setup Profile to Disk
It helps you to save current UEFI settings as an user profile to disk
Load User UEFI Setup Profile from Disk
You can load previous saved profile from the disk
