2.7 Dual Graphics Feature This motherboard supports Dual Graphics Technology. When installing the add-on VGA cards to this motherboard, you are allowed choosing two different ways to decide the function of PCIE2 slot (PCIE x 1), AGI Express slot, and SATA II. The default value of this feature is to enable PCIE2 slot (PCIE x 1), AGI Express slot (only PCI Express x 1), and SATA II. You can also adjust the jumpers to disable PCIE2 slot (PCIE x 1) and SATA II. Then only AGI Express slot (PCI Express x 4) will be enabled. In other words, you are able to adjust the jumpers to enjoy the benefit of Dual Graphics feature. Please refer to the table below for the correct jumper settings.
