Hi Pallas.
Thank you.
I want to find out: is there is any way to set the diffculty (may using diff factor) either on djm's ccminer or this cpuminer, when mining on suprnova?
Thanks
Not that I know of. It is usually done by putting the diff value into the worker or password fields in some way, but I believe it is not implemented into xcn.suprnova right now.
Maybe you could ask ocminer, cause it depends entirely on the pool.
Diff factor or divider is another thing, it just changes the way difficulty from the pool is used, but it doesn't affect its "absolute" value.
