I did change the straps, but they dont make any difference. the clocks changing dont do anything either. on 1200@2000 the hashrate is the same. must be phoenixminer then, that holds back the hashrate or something else.
so you disabled p0 mem state and set p1 @ 2000 and then make your timing changes not strap changes as they are supported in this tool on the RX gddr5 cards
