CPU System Agent Voltage Offset [Auto]
Allows you to configure the amount of voltage fed to the system agent of the processor
including its PCIe controller and power control unit. Increase the voltage when
increasing DRAM frequency.
You can use the <+> or <-> keys to adjust the value. The values range from 0.001V to
0.999V with a 0.001V interval.
CPU Analog I/O Voltage Offset Mode Sign [+]
[+] To offset the voltage by a positive value.
[–] To offset the voltage by a negative value.
CPU Analog I/O Voltage Offset [Auto]
Allows you to configure the amount of voltage fed to the analog 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 when increasing DRAM frequency.
You can use the <+> or <-> keys to adjust the value. The values range from 0.001V to
0.999V with a 0.001V interval.
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]
Allows you to configure 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 when increasing DRAM frequency.
You can use the <+> or <-> keys to adjust the value. The values range from 0.001V to
0.999V with a 0.001V interval.
SVID Support [Auto]
When overclocking, set this item to [Enabled] . Disabling this item would stop the processor
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]
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 2.440V with a 0.001V interval.
CPU Input Voltage [Auto]
Allows you to set an input voltage for the processor 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 0.800V to 2.700V with a 0.010V interval.
