Thank you for your hard work and dedication OP. Quick question:

Why does Bminer state 21sol/s for a stock GTX 1070? Seems a bit exaggerated....
I'm running a pretty heavy overclock (80 power limit, +120 core clock, +500 memory) and I max out at 18sol/s... (5%-8% rejected shares)

Win 10, maxed out virtual memory, connected to US sparkpool, using Bminer v12.2.0...
I've tried both Bminer and Gminer... both max out at 18sol/s per GTX 1070 with OC.

Please advise, thank you.
