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 when you set the CPU Voltage Mode item to [Manual] and allows you
to set a xed CPU voltage. The values range from 0.85V to 1.60V 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.
3.5.12 IMC Voltage [Auto]
Allows you to set the CPU Integrated Memory Controller voltage. The values range from
1.10V to 1.20 with a 0.05V interval.
3.5.13 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.2V to 2.20V with a 0.10V
interval.
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 2.15V with a 0.05V
interval.
3.5.15 PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 1.05V to 1.40V
with a 0.05V interval.
The system may need better cooling system to work stably under high voltage settings.
3.5.16 iGPU Voltage [Auto]
Allows you to set the integrated GPU voltage. The values range from 1.0V to 1.15V with a
0.05V interval.
