I upgraded to a Gigabyte GA-970A-UD3P (ver1.0) and everything booted OK as far the the password input, (running Mint Mate 17) where I found the keyboard didn't work. Tried different USB sockets, all USB2's dead, but the two USB3's are OK.
After much 'looking and testing' in BIOS, noted that RAM voltage was 1.5Volts, clicked XMP and chose profile 1, this upped voltage to the correct 1.65V.
Now USB2's were 'intermittent', sometimes re-plugging would get them to work, but after a reboot often that socket would not work again.
Again in BIOS, discovered that enabling IOMMU Input Output Memory Management Unit (for AMD), got all USB2's working and seemingly stable.
Can anyone with more knowledge than me comment on what I have done and tell me why this works and if its likely to be OK long term
Following is the details of my system:
