personally, Im going to rebase the ProgPoW fork on top of the current master branch. but the current master branch is too unstable. anyway keep going greate work!!

With same verbosity please. There were also stratum messages.

[AndreaLanfranchi]

Strange thing is cuda-0 and cuda-2 properly detect abnormal DAG size and stop while cuda-2 tries to generate a 260 B dag file wich has no meaning.

Which is your --dag-loadmode parameter ?

[hackmod]

no --dag-loadmode parameter

[AndreaLanfranchi]

Solved.

[hackmod]

works nicely!!
