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 specications, 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 voltage for the I/O on the PCH. 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 Platform Controller Hub voltage. 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 to work stably under high voltage settings.
DRAM CTRL REF Voltage [Auto]
Allows you to set a fraction of DRAM voltage as reference on the control lines. 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]
Allows you to set the DRAM DATA Reference Voltage on Channel A/B. 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 conguration.
[Disabled] Enhances the BCLK overclocking ability.
[Enabled] Sets to [Enabled] for EMI control.
