PCH Voltage [Auto]

This item allows you to set the Core voltage for the PCH (Platform Controller Hub). You can use the <+> or <-> keys to adjust the value. The values range from 0.70 V to 1.80 V with a 0.0125 V interval.

• The values of the CPU PLL Voltage, CPU Manual Voltage, CPU Offset Voltage, iGPU Manual Voltage, iGPU 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 for a more stable performance under high voltage settings.

PCH VLX Voltage [Auto]

This item allows you to set the I/O voltage on the PCH (Platform Controller Hub). You can use the <+> or <-> keys to adjust the value. The values range from 1.2000 V to 2.0000 V with a 0.0125 V interval.

VTTDDR Voltage [Auto]

This item allows you to set the termination voltage for the system memory. You can use the <+> or <-> keys to adjust the value. The values range from 0.6000 V to 1.0000 V with a 0.0125 V interval.

DRAM CTRL REF Voltage [Auto]

This item allows you to set the DRAM reference voltage on the control lines from the memory bus. You can use the <+> or <-> keys to adjust the value. The values range from 0.39500x to 0.63000x with a 0.00500x interval.

To set a value for the DRAM reference voltage, we recommend you to set a value close to the standard value which is 0.500000x.

DRAM DATA REF Voltage on CHA/CHB [Auto]

This item allows you to set the DRAM reference voltage on the data lines on Channels A and B. You can use the <+> or <-> keys to adjust the value. The values range from 0.39500x to 0.63000x with a 0.00500x interval.

To set a value for the DRAM reference voltage, we recommend you to set a value close to the standard value which is 0.500000x.

Clock Crossing Boot Voltage [Auto]

This item allows you to increase the value of the clock crossing boot voltage when the rising edge of the BCLK DN is equal to the falling edge of the BCLK D+. You can use the <+> or <-> keys to adjust the value. The values range from 0.1 V to 1.9 V with a 0.00625 V interval.

Clock Crossing Reset Voltage [Auto]

This item allows you to increase the value of the clock crossing reset voltage when the rising edge of the BCLK DN is equal to the falling edge of the BCLK D+. You can use the <+> or <-> keys to adjust the value. The values range from 0.1 V to 1.9 V with a 0.00625 V interval.
