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.
3.5.16
IMC Voltage [Auto]
Allows you to set the CPU Integrated Memory Controller voltage. The values range from 1.1V
to 1.7V with a 0.00625V interval.
3.5.17
DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.2V 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 2. DRAM overvoltage
setting on page 2-27 for details.
•
According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect
the CPU.
3.5.18
CPU PLL Voltage [Auto]
Allows you to set the CPU PLL voltage. The values range from 1.8V to 2.5V with a 0.0125V
interval.
3.5.19
PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 1.05V to 1.5V
with a 0.0125V interval.
•
The values of the IMC Voltage, DRAM Voltage, CPU PLL Voltage and PCH Voltage
items are labeled in different color, indicating the risk levels of high voltage settings.
Refer to the table on the next page for details.
•
The system may need better cooling system to work stably under high voltage
settings.
