I don't think you understand how dual mining on claymore works.
I will try to explain, claymore main principle is ETHASH algo based as PRIMARY and LBRY, PASC/PASL, DECRED (probably the 1st coin on dual mining), SIA as secondary coin.
It is programmed in such a way where you can't use any other above non listed algos.
Hope it makes sense, if not please let me know, i can elaborate.
Thanks.
Right, I understand if it's not supported by claymore, you can't run it. What I mean is if you use a different miner, so effectively running two different mining softwares at the same time.
