PCH PLL Voltage
PCH PLL voltage helps BCLK overclocking, also slightly improves memory
overclocking.
VCCIO Voltage
Configure the voltage for the VCCIO.
Boot CPU PLL Voltage
CPU PLL voltage for BCLK and memory training. CPU PLL volt helps BCLK
overclocking, also slightly improves memory overclocking. Setting this voltage
higher helps CPU cold bug under LN2 cooling. Keep CPU PLL Voltage around
1.650V-1.800V will improve cold bug under LN2 benching.
Eventual CPU PLL Voltage
CPU PLL Voltage used for botting into OS. CPU PLL volt helps BCLK overclocking,
also slightly improves memory overclocking. Setting this voltage higher helps CPU
cold bug under LN2 cooling. Keep CPU PLL Voltage around 1.650V-1.800V will
improve cold bug under LN2 benching.
VCCSA Voltage
Configure the voltage for the VCCSA.
VCC PLL Voltage
VCC PLL helps BCLK overclocking. Also this voltage rail is input source of CPU
internal PLL voltage. Please set this voltage as 1.400V~1.500V when CPU is under
LN2 benching. Very few CPU requests 2.500V~2.800V to get rid of cold bug.
CPU Cold Bug Killer Voltage
CPU Cold Bug Killer Voltage. Recommended to set 2.200V~2.400V for Ln2
benching. It will solve most of CPU cold bug.
CLK VDD Voltage
Configure the CLK VDD Voltage.
