1* PCIe x16_1 and PCIe x16_4 slots share the same bandwidth. PCIe x16_4 slot support up to x8 mode.
2* When using a 28-lane CPU, the PCIe x16_3 slot support up to x8 mode.
3* The PCIe x16_2 shares bandwidth with USB 3.1 and PCIe x1_2 slot. By default, the PCIe x16_2 slot automatically runs at x1 mode.
4* M.2 shares bandwidth with U.2, only one device can be activated at a time.
5* Due to chipset behavior, The SATA6G_78, SATA6G_910 ports (black) do not support IRST including RAID configuration.
6* These functions will work depending on the CPU installed.
