0.005V interval.
PCH Voltage [Auto]
Allows you to set the Platform Controller Hub volage. The values range from 0.7350V to
1.6850V with a 0.005V interval.
VCCSA Voltage [Auto]
Allows you to set the VCCSA voltage. Conguration options: [Auto] [+0.10V]
CPU PLL Voltage [Auto]
Allows you to set the CPU and PCH PLL voltage. Conguration options: [Auto] [+0.10V]
• The values of the CPU Manual Voltage, CPU Offset Voltage, DRAM Voltage, VCCIO
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.
