SVID Support [Auto] Set this item to [Enabled] when overclocking your system. Disabling this item stops the CPU from communicating with the external voltage regulator. Configuration options: [Auto] [Disabled] [Enabled] The following item appears only when you set SVID Support to [Enabled]. SVID Voltage Override [Auto] This item allows you to set the SVID Voltage override. By default, this item takes the standard value of the installed CPU. You can use the or keys to adjust the value. The values range from 0.001V to 2.440 V with a 0.001 V interval. CPU Input Voltage [Auto] This item allows you to set an input voltage for the CPU by the external voltage regulator. By default, this item takes the standard value of the installed CPU. You can use the or keys to adjust the value. The values range from 0.800 V to 2.700 V with a 0.010 V interval. DRAM Voltage [Auto] This item allows you to set the DRAM voltage. You can use the or keys to adjust the value. The values range from 1.20 V to 1.92 V with a 0.005 V interval.
