CPU Offset Mode Sign [+]
This item appears only when you set the CPU Voltage item to [Offset Mode].
[+]
To offset the voltage by a positive value.
[–]
To offset the voltage by a negative value.
Some of the following items are adjusted by typing the desired values using the numeric
keypad and press the
value. To restore the default setting, type [auto] using the keyboard and press the
key.
CPU Offset Voltage [Auto]
This item appears only when you set the CPU 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.
Refer to the CPU documentation before setting the CPU voltage. Setting a high voltage
may damage the CPU permanently, and setting a low voltage may make the system
unstable.
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 0.005 to 0.635V 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.
•
The values of the CPU Manual Voltage, CPU Offset Voltage, iGPU Manual Voltage,
iGPU Offset Voltage, DRAM 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.
