Connectors with shared bandwidth
• When M.2_2 is occupied by an M.2 PCIe SSD, PCIe x16_2, PCIe x1_1, and PCIe
x1_2 will be disabled.
• PCIe x16_2 runs x2 when PCIe x1_1 or PCIe x1_2 is occupied.
• For Conguration A, please adjust BIOS setting for changing onboard device
conguration.
• M.2_1 shares bandwidth with SATA6G_56. When M.2_1 is populated, SATA6G_56
will be disabled.
