SOMEBODY HELP!!

I have 3 boards and I manage by RPI and when they are running sometimes they compile the same block. There are lots of duplicate blocks in cgminer.
How can i solve it? Can somebody help me? Any ideas?

Thanks:)

At least provided us with screenshot & your setting.

Your setting to high.
Best results 23-24 Gh/s (16 chips) in terms of stability and clocking are observed at 1100mV core voltage + 1500 MHz Clock

+1 on Zich,
besides:
you can always calc your pool reject rate % as A/R*100 in your case for hexc 1: 440/17088*100 = 2.57% - this depends on variance also

If all is good including your pool conectivity it should be below 0.5%

But once again az Zich said try it 1500/1100 you should be getting stable 23Gh+ per board

And check your psu with your setings you should be able to provide about (guess) 9A/12 per board. move your molexes on different lines. If they are on a single line voltage drop is huge + the chance for them to melt also
From a point on OC matters for your power bill only + increasing the chance for board failure Wink

And decreasing your hashrate also. Life sucks sometimes Grin
