Z490 Pro4 VCCST Voltage Configure the voltage for the VCCST. VCCIO Voltage Configure the voltage for the VCCIO. VCCSA Voltage Configure the voltage for the VCCSA. PLL Voltage Configuration 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. CPU Internal PLL Voltage Default is 0.900V. Each step is 0.0175V.
