The Sia network hardforked to reject all ASICs on the network except for Obelisk miners on October 31st at a block height of 179,000. I tried to mine it after fork using CCminer on GTX 1070 and had no sucess. Anyone mining SIA on GPU?
I think you can mine SIAcoin with Claymore Miner you check their thread here
https://bitcointalk.org/index.php?topic=1433925.0Download the latest Claymore miner and then remove the ethereum pool from the bat script and put your siacoin pool you can also find the guide from the the link above.
Why delete ethereum pool from bat script? Your answer is stupid.
You cannot mine original SIA with dual Miner. Sia has forked and so claymore must update his miner too.
