Chapter 2

Follow the instructions below to to upgrade the maximum adjustment value of CPU/ QPI/ DDR/ IOH voltage.

Switch 1 : is used to upgrade the CPU voltage adjustment range, switching it to “ON” will upgrade the CPU voltage adjustment range in BIOS.

Switch 2 : is used to upgrade the QPI voltage adjustment range, switching it to “ON” will upgrade the QPI voltage adjustment range in BIOS.

Switch 3 : is used to upgrade the DDR voltage adjustment range, switching it to “ON” will upgrade the DDR voltage adjustment range in BIOS.

Switch 4 : is used to upgrade the IOH voltage adjustment range, switching it to “ON” will upgrade the IOH voltage adjustment range in BIOS.

Important

While you enable OC Genie to detect your system configuration, please don’t turn on any parts of V-switch simultaneously. That behavior would offer too much voltage for device and would be possible to cause some damage of device.

After you set the CPU/ QPI/ DDR/ IOH voltage in BIOS, you can check the CPU/ QPI/ DDR/ IOH voltage by measuring the Voltage Check Point with multimeter. Please refer the following instructions to measure these voltages.
