Untied Overclocking Technology - ASROCK X79 Extreme7 Quick Installation Manual

2.18 Untied Overclocking Technology

This motherboard supports Untied Overclocking Technology, which means during
overclocking, BCLK enjoys better margin due to fi xed 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 fi xed mode so that BCLK can operate
under a more stable overclocking environment.
Please refer to the warning on page 9 for the possible overclocking risk
before you apply Untied Overclocking Technology.
