DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.20V to 1.99V with a 0.005V
interval.
According to Intel CPU specifications, DIMMs with voltage requirement over 1.65V may
damage the CPU permanently. We recommend you install the DIMMs with the voltage
requirement below 1.65V.
VCCSA Voltage [Auto]
Allows you to set the VCCSA voltage. The values range from 0.80V to 1.70V with a 0.00625V
interval.
CPU PLL Voltage [Auto]
Allows you to set the CPU and PCH PLL voltage. The values range from 1.20V to 2.20V with
a 0.00625V interval.
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.
