For me v7 and heavy worked ok, haven and stellite crashed. Didn't test others.
For me stellite is working fine on one machine, but crashing on another. Same pool. Very similar rigs: one is z370a with a mix of 470/480 cards all 4gb (1.6.1 crashes, so I'm using 1.5.9); the other is z270a with a mix of 570/580 cards (some are 4gb and some are 8gb) - on this one 1.6.1 works fine.
