How did you measure it? What cards do you use? I see much less jump, may be 5-10%.
Guys, can someone with a wattmeter measure the exact power consumption of v8 and v9 compared to scrypt mining? Cause we may be close to the edge, when even xpm gpu mining becomes unprofitable in terms of electricity bills...
4x 290 Tri-X, v8 1050W, v9 1130W, script 1320W, but values are not constant
