*1 The M.2_1 Socket shares bandwidth with the SATA_5/6 ports, and therefore the SATA_5/6 ports cannot be used when an M.2 device is installed.
*2 The M.2_2 Socket shares bandwidth with the SATA_3/4 ports, and therefore the SATA_3/4 ports cannot be used when an M.2 device is installed.
*3 Use a chassis with HD audio module in the front panel to support an 8-channel audio output.
*4 To Support Windows 7 64-bit, It need to install an AMD Ryzen™ 2nd Generatione & Ryzen™ 1st Generation Processors.
