Why Decred, Siacoin, Lbry, and Pascal?
I am guessing that Claymore has a large client that wants to mine those coins, but are there other requirements for a coin's hashing algo or miner so that it can be dual mined (easily) by Claymore?
Thats pretty low for Sia. I've got a 7970 and it gets 12.5MH/s ETH plus 620MH/s Sia. You probably want to add the -dcri xx argument I have mine set at -dcri 49 and it gives me double the Sia while only lowing ETH by like 0.5 MH. You can tweak the -dcri value in the runtime using the +/- keys. Then hit "S" for stats and you can find your best ratio. Then put that in the start bat.
Try UBQ, MUSIC or EXP you'll get 25 MH/s due to the smaller DAG, I'd also go easy on the SC with these older cards. I underclock mine and run the fan at 100% BTW.
Are you saying that one can mine these coins as option in the dual-mining mode? If so, how can I tell which coins I can mine in dual in addition to the official ones?
There are plenty pages talking and showing how to mine dual coins bro... just read some page behind and you will find response
