2.17 Untied Overclocking Technology

This motherboard supports Untied Overclocking Technology, which means during overclocking, BCLK enjoys better margin due to fixed PCI / PCIE buses. Before you enable Untied Overclocking function, please enter “Overclock Mode” option of UEFI setup to set the selection from [Auto] to [Manual]. Therefore, BCLK is untied during overclocking, but PCI / PCIE buses are in the fixed mode so that BCLK can operate under a more stable overclocking environment.

Please refer to the warning on page 11 for the possible overclocking risk before you apply Untied Overclocking Technology.
