Sp-mod #6 is 9% faster than sp-mod #3 on the gtx 1070 if you use the latest driver. (384.94) and 100% tdp. (Donate 0.05B BTC to subscribe to my private miner)
The krnlx kernel is broken if you mine on high difficulty (vardiff). Try supernova with highend cards rigs.
You only get payed for 80% of the hash showed in the miner.
send me spmod 6 and I will run the test again. It can be that there is an issue on variable diff. I didn't test that yet as I set it to static 1.0 diff.
