Hi guys,
now I bought a little mining rig with 3 Sapphire hd 7950 boost. The cards came today and at this moment we only have 2 cards running in a case. I live in Germany an have to pay $0.36-0.37 for one kilo watt. Now I found a way to get 650kh/s with each card but the power consumption is rather high. I read about people who only paid 5cents per kw/h, so that power consumption is not significant. Here in Germany the power costs are half of my earnings.
So I use the cgminer. I know, that theoretically matters are the parameters thread-concurrency, gpu-engine and gpu-memclock.
So what is the best way to find the sweet spot? From the 650kh/s solution, should I try all parameters at 75%, 80%, 85%, 90%, 95%? Or that with every parameter? Should I try just to turn down one of these parameters?
Any ideas?
Thanks you
