CPU Digital I/O Voltage Offset Mode Sign [+]
[+] To offset the voltage by a positive value.
[–] To offset the voltage by a negative value.
CPU Digital I/O Voltage Offset [Auto]
This item allows you to set the amount of voltage fed to the digital portion of the I/O
on the processor. By default, this item takes the standard value of the installed CPU.
Increase the amount of voltage to enhance the overclocking capability.
You can use the <+> or <-> keys to adjust the value. The values range from 0.001 V to
0.999 V with a 0.001 V interval.
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.
Conguration 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.
According to Intel
®
CPU specications, 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 set the Core voltage for the PCH (Platform Controller Hub). You can
use the <+> or <-> keys to adjust the value. The values range from 0.70 V to 1.80 V with a
0.0125 V interval.
The values of the CPU PLL Voltage, CPU Manual Voltage, CPU Offset Voltage,
iGPU Manual Voltage, iGPU Offset Voltage, DRAM Voltage, VCCSA Voltage, VCCIO
Voltage, and PCH Voltage items are labeled in different color, indicating the risk levels
of high voltage settings.
The system may need better cooling system for a more stable performance under high
voltage settings.
