CPU PLL Voltage [Auto]

Allows you to set the CPU PLL voltage. The values range from 1.25V to 2.50V with a 0.00625V interval.

Skew Driving Voltage [Auto]

Allows you to set the Skew Driving Voltage. The values range from 0.40V to 1.60V with a 0.00625V interval.

2nd VCCIO Voltage [Auto]

Allows you to set the second VCCIO voltage. The values range from 0.40V to 1.70V with a 0.00625V interval.

PCH Voltage [Auto]

Allows you to set the Platform Controller Hub voltage. The values range from 0.8000V to 1.6000V with a 0.00625V interval.

• The values of the CPU Manual Voltage, iGPU Offset Voltage, DRAM Voltage, VCCSA/ IO Voltage, CPU PLL Voltage, and PCH Voltage items are labelled in different colors, indicating the risk levels of high voltage settings.

The system may need better cooling system to work stably under high voltage settings.

VTTDDR Voltage [Auto]

Allows you to set the VTTDDR voltage for DRAM channel. The values range from 0.6250V to 1.1000V with a 0.00625V interval.

DRAM CTRL REF Voltage on CHA/B [Auto]

Allows you to set the DRAM Control Reference Voltage on Channel A/B. The values range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM overclocking ability.

BCLK Skew [Auto]

Reduce to increase BCLK and increase to reduce BCLK.

Configuration options: [Auto] [-12]—[+12]

CPU I/O Skew [Auto]

This setting allows you to increase the overclocking capability.

Configuration options: [Auto] [-4]—[+4]

DMI Skew [Auto]

This setting allows you to increase the overclocking capability.

Configuration options: [Auto] [-4]—[+4]
