PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 0.80V to 1.70V
with a 0.01V interval.
• The values of the CPU PLL Voltage, CPU Manual Voltage, CPU Offset Voltage,
iGPU Manual Voltage, iGPU Offset Voltage, DRAM Voltage, VCCSA 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.
• When you enable the OV_CPU/DRAM jumper, the CPU Manual Voltage and DRAM
Voltage increases to a maximum 2.3V range.
DRAM DATA REF Voltage on CHA/B [Auto]
Allows you to set the DRAM DATA Reference Voltage on Channel A/B. The values
range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM
overclocking ability.
DRAM CTRL REF Voltage on CHA/B [Auto]
Allows you to set the DRAM Control Reference Voltage on Channel A/B. The values
range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM
overclocking ability.
