iGPU Manual Voltage [Auto]
This item appears only when you set the iGPU Voltage item to [Manual Mode] and allows
you to set a fixed iGPU voltage. Use the <+> and <-> keys to adjust the value. The values
range from 0.800V to 1.990V with a 0.005V interval.
DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.185V to 2.135V with a 0.005V
interval.
According to Intel CPU spec, 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 0.610V to 1.560V with a 0.005V
interval.
PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 0.7350V to
1.6850V with a 0.005V interval.
CPU PLL Voltage [Auto]
Allows you to set the CPU and PCH PLL voltage. Configuration options: [Auto] [+0.10V]
• The values of the CPU Offset Voltage, iGPU Offset Voltage, DRAM Voltage,
VCCSA 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.
