Hi guys...

i have got a problem...my S7 is not hashing normal. When the 3 boards are plugged, only doing 3500gh/s. I did search step by step and i found the "wrong" board. ASIC chips are ok but not hasing and after 4 min its start beeping. Any ideas?

You are way overclocking those boards.

Most of the 54 chip boards have a default clock speed of 575 to reach a total of ~4.8th. Even the custom 5.67th models only ran a 675 default clock. It looks like you killed one of your boards with that overclock.

Also the ASIC chips are NOT ok in your second screenshot. It should be seeing 54 and it is only seeing 48 meaning there are 2 dead clusters of chips which is why it will not hash.

Stop buying industrial miners, running them at home, and then complaining about the noise.
