I just started doing b2s dual mining with every type of cards and I have to admit that is works like a charm.
Does not impact ETH performances at all and also the power consumptions does not seem to be changed in a measurable way.
I am using -dcri 30.
Does someone have different performances or has any advice?
use the "+" button to increase the intensity till you start seeing it affect Eth... then use the "-" to go back
your -dcri should be about 35 - this is where you max out on blake 2s hash without affecting Eth Hash.. 30 is the default
Good Luck and happy mining
