Ring 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.
