Chapter 3
According to Intel CPU spec, DIMMs with voltage requirement over 1.5V may damage the
CPU permanently. We recommend you install the DIMMs with the voltage requirement
below 1.5V.
VCCIO Voltage [Auto]
Allows you to set the VCCIO voltage. The values range from 0.90V to 1.70V with a 0.01V
interval.
VCCSA Voltage [Auto]
Allows you to set the VCCSA voltage. The values range from 0.77V to 1.60V with a 0.01V
interval.
CPU PLL Voltage [Auto]
Allows you to set the CPU PLL voltage. The values range from 1.20V to 2.20V with a 0.01V
interval.
Load-Line Calibration [Auto]
Load-line is defined by Intel VRM spec 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.
Configuration options: [Auto] [Disabled] [Enabled]
The actual performance boost may vary depending on your CPU specification.
CPU Spread Spectrum [Auto]
[Auto] Automatic configuration.
[Disabled] Enhances the BCLK overclocking ability.
[Enabled] Sets to [Enabled] for EMI control.
