Chapter 2: BIOS information 2-15
2.4.8 iGPU Offset Mode Sign [+]
[+] To offset the voltage by a positive value.
[–] To offset the voltage by a negative value.
iGPU Voltage [Auto]
Allows you to set the iGPU voltage. The values range from -0.635V to +0.635V with a 0.005V
interval.
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 specification, 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 VCCIO Voltage [Auto]
Allows you to set the VCCIO voltage. The values range from 0.735V to 1.685V with a 0.005V
interval.
2.4.11 PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 0.735V to
1.685V with a 0.005V interval.
• The values of the CPU Voltage, iGPU Voltage, DRAM 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.
2.4.12 Load-Line Calibration [Auto]
Load-line is defined by Intel VRM specification and affects CPU voltage. The CPU working
voltage will decrease proportionally to CPU loading. Higher load-line calibration would get
higher voltage and better overclocking performance, but increase the CPU and VRM thermal.
This item allows you to set this function for better system performance. Configuration options:
[Auto] [Disabled] [Enabled]
The actual performance boost may vary depending on your CPU specification.
