try different pool

Sounds like only 1 of your 3 boards is hashing.

Check the connectors to the blades. Like fanatic said there's only one blade functioning, take a pic of the blades if possible. Not sure if it is just me but the link doesn't work. Take another picture of the blades and also the main UI.

Thanks. I knew it . I change my Frequency from 700M to 1000M . It run slowly

[fanatic26]

There is no way you can clock it to 1000 without burning up the hardware. That was a very bad decision.

Ya ,thank you. What Frequency did you choose ?
