ASROCK Z590 Steel Legend WiFi 6E User Manual page 84

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.

AVX Configuration
AVX2 Voltage Guardband Scale Factor
AVX2 Voltage Guardband Scale Factor controls the voltage guardband applied to
AVX2 workloads. A value > 1.00 will increase the voltage guardband, and < 1.00
will decrease the voltage guardband.
AVX-512 Voltage Guardband Scale Factor
AVX-512 Voltage Guardband Scale Factor controls the voltage guardband applied
to AVX-512 workloads. A value > 1.00 will increase the voltage guardband, and < 1.00
will decrease the voltage guardband.
