that's sound like incompartible ram for amd chipset.... add more vdimm voltage or loss some timing while choosing the xmp setting...
tweak some timing and memtest

suggest using micron ram chipset always work super with amd......

using 2 days... usb and keyboard still stable connected... hope it stay that way

it just auto enable tpm for your bios and some extra setting........just hope new one fix the usb dc...........

f13 usb dc
F14c usb still dc but F14c let the curve optimiser tweak more lower negative point.... means more stable compare f13

example my gold core need +3 for my gold core and F14c -0 for gold core ........... more stable for pbo2...
