hello
I have Sapphire RX5500 8GB PULSE and its very “sensitive” to changes.
like every OC or change I make ( even just setting the fan, will crash it- it will just restart miner\rig or just keep “mining” at 0 mh\s)
and to undo it, I need to set all the defaults and restart twice.
I did find one OC that works- core 1100 \ mem 945 ( gives 26-27 mh\s @ 65w)
but as I said, I cant change the fan speed, it has to stay auto for the OC to work (or any change basically) which makes it hot.
i tried different miners with no improvement
so did I lose the silicone lottery 
?
any help would be appreciated !!
