CPU Input Voltage [Auto]
This item allows you to set an input voltage for the CPU by the external voltage regulator. By
default, this item takes the standard value of the installed CPU. You can use the <+> or <->
keys to adjust the value. The values range from 0.800 V to 2.700 V with a 0.010 V interval.
DRAM Voltage [Auto]
This item allows you to set the DRAM voltage. You can use the <+> or <-> keys to adjust the
value. The values range from 1.20 V to 1.92 V with a 0.005 V interval.
According to Intel
®
CPU specications, DIMMs with voltage requirement over 1.65 V may
damage the CPU permanently. We recommend that you install the DIMMs with the voltage
requirement below 1.65 V.
PCH Voltage [Auto]
This item allows you to set the Core voltage for the PCH (Platform Controller Hub). You can
use the <+> or <-> keys to adjust the value. The values range from 0.70 V to 1.80 V with a
0.0125 V interval.
• The values of the CPU PLL Voltage, CPU Manual Voltage, CPU Offset Voltage,
iGPU Manual Voltage, iGPU Offset Voltage, DRAM Voltage, VCCSA Voltage, VCCIO
Voltage, and PCH Voltage items are labeled in different color, indicating the risk levels
of high voltage settings.
• The system may need better cooling system for a more stable performance under high
voltage settings.
PCH VLX Voltage [Auto]
This item allows you to set the I/O voltage on the PCH (Platform Controller Hub). You can
use the <+> or <-> keys to adjust the value. The values range from 1.2000 V to 2.0000 V with
a 0.0125 V interval.
VTTDDR Voltage [Auto]
This item allows you to set the termination voltage for the system memory. You can use
the <+> or <-> keys to adjust the value. The values range from 0.6000 V to 1.0000 V with a
0.0125 V interval.
DRAM CTRL REF Voltage [Auto]
This item allows you to set the DRAM reference voltage on the control lines from the memory
bus. You can use the <+> or <-> keys to adjust the value. The values range from 0.39500x to
0.63000x with a 0.00500x interval.
To set a value for the DRAM reference voltage, we recommend you to set a value close to
the standard value which is 0.500000x.
