im sorry to ask a dumb question or maybe its already been done but is there a way we can mine different algos depending on what card it is for instance i have a rig with 3 1080tis and 4 1070's how can i make it mine zec on the 1080s and dual something on the 1070's?
The nvOC bash files aren't set up to handle that granularity, but you can do that with most individual miners manually.
For example, you can run an instance of one miner, set to run only on the three GPU numbers that match the 1070s... and then run an instance of another miner, set to run on the four GPU numbers that match the 1080s.
Note: not all miners support running on particular GPUs. Claymore, for example, does, but there's no guarantee that others do - and you'll have to look into some details for each to get this going.
(I find it simpler to segregate my GPUs into rigs with all the same type.)
