iGPU Voltage [Offset Mode]
[Manual Mode] Allows you to set a fixed iGPU voltage.
[Offset Mode] Allows you to set the iGPU Offset voltage.
iGPU Offset Voltage [Auto]
This item appears only when you set the iGPU Voltage item to [Offset Mode] and
allows you to set the Offset voltage. The values range from 0.005V to 0.635V with a
0.005V interval.
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. 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 1.20V to 2.20V with a 0.00625V
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 0.735V to 1.685V with a 0.005V
interval.
PCH Voltage [Auto]
Allows you to set the Platform Controller Hub volage. The values range from 0.735V to
1.685V with a 0.005V interval.
• The values of the CPU Manual Voltage, CPU Offset Voltage, iGPU Manual 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.
