NVIDIA GTX 1070 - 8GB 450/100 = 4.5 With these settings it's more like 140-150W. I have 2 x 1070GTX and with -150 CORE and 70% POWER LIMIT I have about 110W/card @ 385sols/s.
I run my 1070 as the the same settings you got (nearly, xcept core) and I am having around 470sols/s. %70 Power Limit, +150Core / 600 Memory, Win7, Nicehash. Pulling around 155watts from the wall. (Only 1 GPU+Mobo)
Isn't it better to have your core overclocked for equihash? 385sols/s looks like a bit low.
