iGPU Offset Mode Sign [+]
This item allows you to offset the iGPU voltage by a positive or negative value. Select allows you to offset the iGPU voltage by a positive or negative value. Select a
method, and then offset the voltage by adjusting the iGPU Voltage item.
[+] To offset the voltage by a positive value.
[–] To offset the voltage by a negative value.
iGPU Voltage [Auto]
This item allows you to set a xed iGPU voltage. You may offset the iGPU voltage fromllows you to set a xed iGPU voltage. You may offset the iGPU voltage from
-0.635V to +0.635V with a 0.005V interval, depending on the iGPU Offset Mode Sign setting
and the CPU model you installed.
DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.20V to 2.20V with a 0.01V
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.
VCCIO Voltage [Auto]
Allows you to set the VCCIO voltage. The values range from 0.80V to 1.70V with a 0.01V
interval.
CPU PLL Voltage [Auto]
Allows you to set the CPU PLL voltage. The values range from 1.20V to 2.20V with a 0.01V
interval.
PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 0.80V to 1.45V
with a 0.01V interval.
• The values of the CPU Voltage, DRAM Voltage, VCCIO Voltage, CPU PLL Voltage,
and PCH Voltage items are labeled in different color, indicating the risk levels of high
voltage settings. Refer to the table below for details.
• The system may need better cooling system to work stably under high voltage settings.
