CPU SVID Support [Auto]

Set this item to [Enabled] when overclocking. Disabling this item prevents the CPU from communicating with the external voltage regulator.

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

The following items appear only when you set the CPU Core Voltage to [Auto] or [Disabled].

SVID Voltage Override[Auto]

This item allows you to set a VCCIN for the CPU during initial part of POST. Use the <+> or <-> key to adjust the value. The values range from 0.001 V to 2.440V at 0.001V increment.

SVID VDDQ Voltage Override [Auto]

This item allows you to set a VCCIN for the CPU before OS loading. Use the <+> or <-> key to adjust the value. The values range from 0.001V to 2.440V at 0.001V 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 0.80V to 1.90V at 0.010V 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 0.70V to 1.80V at 0.00635V 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 1.20V to 2.20V at 0.00635V 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 0.7000V to 1.8000V at 0.00625V increment.
