Maybe check if any of the capacitors on the motherboard or RX6500 looks 
damaged. Here are some examples what they normally look like:

When capacitors are damaged they usually look like a balloon instead of 
a cylinder because electrolyte liquid inside started to boil because of 
a shortcut.

Capacitors are used to suppress voltage and spikes and valleys. When 
they are damaged the electronics might still work, but becomes unreliable.

That's a really strong evidence that you have a hardware problem here.

BTW: Where do you got that hardware from? Is it used or a new one? Was 
it maybe used for mining?
