2.5.21 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.
2.5.22 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] [�nabled]
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.
2.5.23 Extreme OV [Disabled]
Disable this item to help protect the CPU from being burned by Over Voltage. When you
enable this item, you can choose a high level voltage to overclock, but will not guarantee the
CPU life.
Configuration options: [�nabled] [Disabled]
2.5.24 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 2.7V with a 0.010V interval.
2.5.25 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. You can use the <+> or <-> keys to adjust the value.
The values range from 1.20V to 1.92V with a 0.01V interval.
According to Intel ® CPU specifications, DI��s 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.
