*1 The M.2 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 Use a chassis with HD audio module in the front panel to support an 8-channel audio output.
*3 Windows 7 64-bit is only supported when using AMD Ryzen™ 2nd Generation/ Ryzen™ 1st Generation Processors.
