• The values of the CPU Voltage, CPU Offset Voltage, VDDNB Offset Voltage, VDDNB
Manual Voltage, DRAM Voltage, SB 1.1V Voltage, 1.1VSB Voltage, APU1.2V
Voltage, VDDA Voltage, NB VREF Voltage, DRAM VREFCA Voltage, and DRAM
VREFDQ Voltage items are labeled in a different color, indicating the risk levels of high
voltage settings.
• The system may need better cooling system to work stably under high voltage settings.
