PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 1.05V to 1.40V
with a 0.05V interval.
• The values of the CPU Manual Voltage, CPU Offset Voltage, DRAM Voltage, VCCSA
Voltage, and PCH Voltage items are labeled in different color, indicating the risk levels
of high voltage settings.
• The system may need better cooling system to work stably under high voltage
settings.
