CPU Input Voltage [Auto]

This item allows you to configure the input voltage for the CPU by the external voltage regulator. Use the <+> or <-> key to adjust the value. The values range from 0.80 V to 2.70 V at 0.010 V increment.

DRAM SVID Support [Auto]

Set this item to [Disabled] to stop the CPU from communicating with the external voltage regulator. Disable this item when you overclock your system.

Configuration options: [Auto] [Disabled] [Enabled]

DRAM Voltage (CHA/CHB, CHC/CHD) [Auto]

This item allows you to set the voltage for the system memory. Use the <+> or <-> key to adjust the value. The values range from 0.80 V to 1.90 V at 0.010 V increment.

According to Intel® CPU specifications, DIMMs with voltage requirement over 1.65 V may damage the CPU permanently. We recommend that you install the DIMMs with the voltage requirement below 1.65 V.

PCH Core Voltage [Auto]

This item allows you to configure the core voltage for the PCH (platform controller hub). Use the <+> or <-> key to adjust the value. The values range from 0.70 V to 1.80 V at 0.00625 V increment.

PCH I/O Voltage [Auto]

This item allows you to configure the I/O voltage for the PCH (platform controller hub). Use the <+> or <-> key to adjust the value. The values range from 1.20 V to 2.20 V at 0.00625 V increment.

VCCIO CPU 1.05V Voltage [Auto]

This item allows you to set the main power supply for the CPU REF. Use the <+> or <-> key to adjust the value. The values range from 0.7000 V to 1.8000 V at 0.00625 V increment.

VCCIO PCH 1.05V Voltage [Auto]

This item allows you to set the tmain power supply for the PCH REF. Use the <+> or <-> key to adjust the value. The values range from 0.7000 V to 1.8000 V at 0.00625 V increment.

VTTDR Voltage (CHA/CHB) [Auto]

This item allows you to set the termination voltage for the DRAM on the left. Use the <+> or <-> key to adjust the value. The values range from 0.2000 V to 1.0000 V at 0.00625 V increment.

VTTDR Voltage (CHC/CHD) [Auto]

This item allows you to set the termination voltage for the DRAM on the right. Use the <+> or <-> key to adjust the value. The values range from 0.2000 V to 1.0000 V at 0.00625 V increment.
