Imc Voltage; Dram Voltage; Cpu Pll Voltage; Pch Voltage - Asus P7H57D-V EVO User Manual

Offset Sign [-]
This item appears only when you set the Offset Voltage item to a value other than [Auto].

[–]
Fixed Voltage [Auto]
This item appears only when 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 1.7V 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.
3.5.18 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.
3.5.19 DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.20V to 2.5V* with a 0.0125V interval.

3.5.20 CPU PLL Voltage [Auto]
Allows you to set the CPU PLL voltage. The values range from 1.8V to 2.2V with a 0.0125V
interval.
3.5.21 PCH Voltage [Auto]
Allows you to set the Platform Controller Hub voltage. The values range from 1.05V to 2.0V
with a 0.00625V interval.

To offset the voltage by a positive value.
To offset the voltage by a negative value.
The value [2.5V] of the DRAM Voltage item is supported only if the OV_DRAM jumper
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 2-22 for details.
According to Intel CPU spec, DIMMs with voltage requirement over 1.65V may
damage the CPU permanently. We recommend you install the DIMMs with the voltage
requirement below 1.65V.
The values of the IMC Voltage, DRAM Voltage, and CPU PLL Voltage items are
labeled in different color, indicating the risk levels of high voltage settings. Refer to the
table below for details.
The system may need better cooling system to work stably under high voltage settings.
