Hi, I have 2 Radeon R7 200 - crossifre (2GB ram) and 8 core AMD - mining Zcash
I have +- GPU - 0 = 46 H/s and GPU - 1 = 150 H/s
Why one card has lower H/s?
Is there any way to make more effective mining process (I have overclocked already)?
Is it efficient to mine from the consumption perspective? I have +- 500W
Can I tune-up config file somehow?
