Alright, I am now mining Alloy and there are some issues, I am still using the 18.6.1 which is great on CN7, on Alloy/heavy I get about half that hash power which is natural. But I seem to get some STALE shares and also the moment DevFee kicks in, I get a crash or ruined miner needing a reset for normalization. I am going to install 18.3.4 as you said which is supposed to be better on heavy algos and see if it improves.
