The values of CPU Manual Voltage and CPU Offset Voltage vary with CPUs.
CPU PLL Voltage [Auto]
Allows you to set the CPU and PCH PLL voltage. Conguration options: [Auto] [+0.10V]
CPU Spread Spectrum [Auto]
[Auto] Automatic conguration.
[Disabled] Enhances the BCLK overclocking ability.
[Enabled] Sets to [Enabled] for EMI control.
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 specications, 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 0.610V to 1.560V with a 0.005V
interval.
PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 1.05V to 1.40V
with a 0.05V interval.
• The values of the CPU Manual Voltage, CPU 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.
