with a 0.01V interval.
• The values of the CPU Manual Voltage, CPU Offset Voltage, DRAM Voltage, VCCSA
Voltage, VCCIO Voltage, 1.8FSR 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.
