Offset Voltage [Auto]
This item appears only when you set the CPU Voltage Mode item to [Offset] and allows you
to set the Offset voltage. The values range from 0.00625V to 0.50000V with a 0.00625V
interval.
Offset Sign [-]
This item appears only when you set the Offset Voltage item to a value other than [Auto].
[+]
To offset the voltage by a positive value.
[–]
To offset the voltage by a negative value.
Fixed Voltage [Auto]
This item appears only whne you set the CPU Voltage Mode item to [Manual] and allows you
to set a fixed CPU voltage. The values range from 0.85V to 2.10V* with a 0.00625V interval.
•
Refer to the CPU documentation before setting the CPU Vcore voltage. Setting a high
VCore voltage may damage the CPU permanently, and setting a low VCore voltage
may make the system unstable.
•
If the OV_CPU switch is enabled, the adjustable voltage range from [1.25V] to [2.1V].
If the OV_CPU switch is disabled, the adjustable voltage range from [0.85V] to [1.7V].
Refer to 4. CPU / IMC / DRAM overvoltage setting switches on page 2-26 for details.
3.5.12
IMC Voltage [Auto]
Allows you to set the CPU Integrated Memory Controller voltage. The values range from 1.1V
to 1.9V* with a 0.00625V interval.
The value [1.9V] of the IMC Voltage item is supported only if the OV_IMC switch is
enabled. Otherwise the maximum voltage supported is [1.7V]. Refer to 4. CPU / IMC /
DRAM overvoltage setting switches on page 2-26 for details.
3.5.13
DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.5V to 2.5V* with a 0.0125V
interval.
•
The value [2.5V] of the DRAM Voltage item is supported only if the OV_DRAM switch
is enabled. Otherwise the maximum voltage supported is [2.0V]. This item can be
automatically optimized if you install a XMP DIMM. Refer to 4. CPU / IMC / DRAM
overvoltage setting switches on page 2-26 for details.
•
According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect
the CPU.
3.5.14
CPU PLL Voltage [Auto]
Allows you to set the CPU PLL voltage. The values range from 1.8V to 2.1V with a 0.1V
interval.
