This motherboard supports Untied Overclocking Technology, which means during
overclocking, FSB enjoys better margin due to fixed PCI / PCIE buses. Before you
enable UntiedOverclocking function, pleaseenter“Overclock Mode” option ofBIOS 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 7 for the possible overclocking risk
before you apply Untied Overclocking Technology.
