Hi I have maybe stupid noob question 
but how did you know that you have 5 cold chips ? it is some way to check to boards ?
After the night in the statistics in my mine I have measures form 230GH/s to 140 GH/s, I have to Antminer and there are stable it maybe 2-3% differential.
tnx for advice

If you go to the API Log, you can see how each of the individual miners (groups of chips) are doing.
As for you widely varying hashrate, again, look at your API Log and you'll be able to see what's going on. If some are hashing at half-rate, then that's the info that 5 chips are cold.
