Hi dok,
I use V7 algo with 4 vega 56
V1.5.4 and V1.5.3 give me 7600h/s, stable
V1.5.2 and previous versions give me 7850h/s, stable
So, I stick to V1.5.2

Have you got an explanation for that ?
for me, the older version are giving the better result, not by much, but still .. for example RX580 on 1.4.6 gives 970 h/s on the 1170/1975 , while with the same core/memory setting it gives 930 h/s on 1.5.2.. so as far as there is no any problems I aware for 1.4.6 I will stick with them.
