First of all, thank you for your reply.
As I have already written in the past message, I am already trying to mine with "lyra2v2-old" parameter and it mines slower
when you say "you could disable it", do you mean to add this "--no-watchdog" ?
if i am not wrong, with ccminer you can add the parameter "-f, --diff-factor Divide difficulty by this factor (default 1.0)" or with enemyminer you can add "
in Z-enemy miner, inside the readme.txt there is written "6) Yiimp pools rec manual diff, like : ( -p d=16 ) - for small farms or (-p d=48 )- for good farms like 6-8 1080ti"
