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
Questions:
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?
i believe to do mining you don’t want to use crossfire. You want each card independent. also when you overclock try to undervolt. And memory Speed is more important than CPU speed on GPU.
That is how i have mine setup. I am new to this whole thing, but i believe when you do crossfire it uses only parts of the cards to work together as a team. What you want is each card working at full capacity.
I think PSU is the culprit here. I had similar problem with my 2x gtx 1060 which I was trying to power with 650W PSU. Upgraded to 750W and problem simply vanished.
Looks like CPU mining right there. But since you said it’s from a laptop GPU that may be the correct numbers I guess. I don’t remember what that nvidia card can produce. Look it up in the forum search! Someone has to have tried with it too.
