I am solo mining with some graphics cards (nvidia 1070 ti) and I have a couple quesitons.
I have 1 graphics card that is mining about 4x the rate of the others… not sure why?
Second quesiton is, I have a very high rejection rate, about 2:1 rejections to accepted shares, what could be the reason for that? I am solo mining the graphics card computer to a stratum server in the LAN but different computer.

Thanks for any advice
EDIT: I’m using lolminer now and rejection rate is now negligible
