HI!

i get 3 HW error in 10 min.  

        Frequency          Volt      Watt     Hw               Temp (chip)

Board 1 :444                7         226       1                   48
Board 2: 444                7         226                            49
Board 3: 400                7         204       2                   42
Board 4: 444                7         226                            45  

Volt is 7 at all board.  

will this be a good setup for longterm use?  

And i did choose to mine dev fee daily instead of every 2 hours,  is that better than every 2 hours?
and if i choose daily, how long will it mine on dev Fee?
