When you switch the OV_CPU/DRAM jumper to enable, the CPU Manual Voltage and 
DRAM Voltage increases to a maximum 2.3V range.
DRAM DATA REF Voltage on CHA/B [Auto]
Allows you to set the DRAM DATA Reference Voltage on Channel A/B. The values 
range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM 
overclocking ability.
DRAM CTRL REF Voltage on CHA/B [Auto]
Allows you to set the DRAM Control Reference Voltage on Channel A/B. The values 
range from 0.395x to 0.630x with a 0.005x interval. Different ratio might enhance DRAM 
overclocking ability.
CPU Spread Spectrum [Auto]
[Auto] 
Automatic configuration.
[Disabled] 
Enhances the BCLK overclocking ability.
[Enabled] 
Sets to [Enabled] for EMI control.
BCLK Recovery [Auto]
Configuration options: [Auto] [Disabled] [Enabled]
