Chapter 2: BIOS information 2-17
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]
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.
iGPU Voltage [Offset Mode]
[Manual Mode] Allows you to set a xed iGPU voltage.
Offset Mode] Allows you to set the offset voltage.
iGPU Offset Voltage [Auto]
Allows you to set the iGPU Offset voltage. The values range from 0.005V to 0.635V with a
0.005V interval.
DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.200V 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.
PCH Voltage [Auto]
Allows you to set the Platform Controller Hub volage. The values range from 0.80V to 1.685V
with a 0.005V interval.
• The values of the CPU Manual Voltage, CPU Offset Voltage, DRAM Voltage, VCCSA
Voltage, VCCIO 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.
VCCSA Voltage [Auto]
Allows you to set the VCCIO voltage. The values range from 0.925V to 1.025V with a 0.1V
interval.
CPU PLL Voltage [Auto]
Allows you to set the CPU and PCH PLL voltage. The values range from 1.80V to 1.90V with
a 0.1V interval.
CPU Spread Spectrum [Auto]
[Auto] Automatic conguration.
[Disabled] Enhances the BCLK overclocking ability.
[Enabled] Sets to [Enabled] for EMI control.
