I didn't know that the A520 doesn't support the 3200G or 3400G APUs. I bought the Prime A520M-K and it worked right out of the box, even before I updated to the latest BIOS. Seems rock stable too with XMP enabled. I only discovered that it shouldn't work on anything earlier than the Renoir 4xxx APUs.
Tomorrow, I am going to try a Pro 4650G on a B450 Aorus board - maybe even one mini ITX and one mATX. I might have to boot with a 3200G first and upgrade to the F51 BIOS, which some rumours say allow the B450 to run Renoir. Not holding my breath. but am hoping a future BIOS will allow this like AMD promised in May
