Some of the following items are adjusted by typing the desired values using the numeric
keypad and press the <Enter> key. You can also use the <+> and <-> keys to adjust the
value. To restore the default setting, type [auto] using the keyboard and press the <Enter>
key.
2.4.8 CPU Voltage [Offset Mode]
[Offset Mode] To offset the voltage by a positive or negative value.
[Manual Mode] Allows you to set a xed CPU voltage.
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.
CPU Offset Voltage [Auto]
Allows you to set the CPU Offset voltage. The values range from 0.005V to 0.635V with a 0.005V
interval.
CPU Manual Voltage [Auto]
This item appears only when you set the CPU Voltage item to [Manual Mode] and allows you
to set a xed CPU voltage. The values range from 0.800V to 1.990V 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.
2.4.9 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 specication, 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.
2.4.10 VCCSA Voltage [Auto]
Allows you to set the VCCSA voltage. The values range from 0.610V to 1.560V with a 0.005V
interval.
2.4.11 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.
2.4.12 CPU PLL Voltage [Auto]
Allows you to set the CPU and PCH PLL voltage. Conguration options: [Auto] [+0.10V]
• The values of the CPU Offset Voltage, CPU Manual 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.
