1* The PCIe x16_4 shares bandwidth with M.2 x4. When M.2 socket is occupied, the PCIe x16_4 slot will be disabled.
2* The PCIe x16_4 shares bandwidth with M.2 x4. When M.2 socket is occupied, the PCIe x16_4 slot will be disabled.The PCIe x16_3 slot support x8 devices only.
3* The PCIe x16_2, PCIe x1_1 and USB3_E56 connectors share the same bandwidth. By default, the PCIe x16_2 slot and PCIe x1_1 slot will automatically run at x1 mode with USB3_E56 enabled for best resource optimization.
4* Due to chipset behavior, The SATA6G_78, SATA6G_910 ports (black) do not support IRST including RAID configuration.
5* These functions will work depending on the CPU installed.
