CPU Digital I/O Voltage Offset [Auto]
Allows you to congure the amount of voltage fed to the digital portion of the I/O on the
processor. Increase the amount of voltage when increasing DRAM frequency. Use the
<+> or <-> keys to adjust the value. The values range from 0.001V to 0.999V with a
0.001V interval.
2.5.21 SVID Support [Auto]
Disabling SVID support stops the processor from communicating with the external voltage
regulator. Conguration options: [Auto] [Disabled] [Enabled]
• We recommend that you disable this function when overclocking.
• The following item appears only when you set SVID Support to
[Enabled].
SVID Voltage Override [Auto]
Allows you to set the SVID Voltage override. Use the <+> or <-> keys to adjust the
value. The values range from 0.001V to 2.440V with a 0.001V interval.
2.5.22 CPU Input Voltage (VCCIN) [Auto]
This item allows you to set the CPU input voltage. The values range from 0.800V to 2.700V
with a 0.010V interval.
2.5.23 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.185V to 1.800V with a 0.005V
interval.
According to Intel CPU specications, DIMMs with voltage requirement over 1.65V may
damage the CPU permanently. We recommend that you install the DIMMs with the voltage
requirement below 1.65V.
2.5.24 PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. Use the <+> or <-> keys to adjust the
value. The values range from 0.735V to 1.500V with a 0.005V interval.
The system may need better cooling system to work stably under high voltage settings.
2.5.25 DRAM CTRL REF Voltage [Auto]
Allows you to set a fraction of DRAM voltage as reference on the control lines. Use the <+>
or <-> keys to adjust the value. The values range from 0.3950x to 0.6300x with a 0.0050x
interval.
2.5.26 DRAM DATA REF Voltage on CHA [Auto]
Allows you to set the DRAM DATA Reference Voltage on Channel A. The values range from
0.3950x to 0.6300x with a 0.0050x interval. Different ratio might enhance DRAM overclocking
ability.
