Chapter 3
DRAM Voltage [Auto]
Allows you to set the DRAM voltage. The values range from 1.185V to 1.800V with a 0.005V
interval.
According to Intel CPU specications, DIMMs with voltage requirement over 1.65V may
damage the CPU permanently. We recommend that you install the DIMMs with the voltage
requirement below 1.65V.
PCH VLX Voltage [Auto]
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 1.185V to 2.135V with a 0.005V
interval.
PCH Voltage [Auto]
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 0.735V to 1.500V with a 0.005V
interval.
The system may need better cooling system for a more stable performance under high
voltage settings.
DRAM CTRL REF Voltage [Auto]
This item is the DRAM reference voltage for the control lines from the memory bus. You can
use the <+> or <-> keys to adjust the value. The values range from 0.3950x to 0.6300x with a
0.0050x interval.
DRAM DATA REF Voltage on CHA/CHB [Auto]
This item is the DRAM reference voltage for the data lines on Channels A and B. You can
use the <+> or <-> keys to adjust the value. The values range from 0.3950x to 0.6300x with a
0.0050x interval. Different ratio might enhance DRAM overclocking ability.
CPU Spread Spectrum [Auto]
[Auto] Automatic conguration.
[Disabled] Enhances the BCLK overclocking ability.
[Enabled] Sets to [Enabled] for EMI control.
