Imc Voltage; Dram Voltage; Cpu Pll Voltage; Pch Voltage - Asus P7P55D-E DELUXE User Manual

• 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 on page 2-27 for details.
3.5.16 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 on page 2-27 for details.
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 4. CPU / IMC / 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 2.0V 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 2.00V
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.
