Before you enable Untied Overclocking function, please enter "Overclock Mode" option of UEFI setup to set the selection from [Auto] to [Manual]. Therefore, CPU FSB is untied during overclocking, but PCI / PCIE buses are in the fixed mode so that FSB can operate under a more stable overclocking environment. Please refer to the warning on page 10 for the possible overclocking risk before you apply Untied Overclocking Technology. 41 Fatal1ty 990FX Professional Series Motherboard English
