GT PLL Voltage
Default is 0.900V. Each step is 0.015V. Adding 9 -15 steps will help CPU PLL to lock
internal clock during High frequency under Ln2 cooling. For example: 1.020V -
1.125V will be proper value. Bu the voltage level will be different on each processor.
User has to find the best value for user's own processor.
