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?
