Antminer S9 running 2/3

Hi,

This is a brand new Antiminer S9 (my first attempt at mining). Can someone help me figure out why it is only running 2/3?

Chain 6 is missing chips, see how it has less o's than the others?  Each o is a chip that is reporting OK, they are all linked in a chain.  For some reason, a chip is bad in your chain 6 and preventing the others below it from working.

You could try powering down and switching around the ribbon cables, but this seems like a hardware defect that you need to report to bitmain.  Sorry.

Thank you. I have already contacted Bitmain (no reply). I was hoping there was something I was overlooking.

I say limp along at 11GH and get a few hundred bucks while you wait for bitmain.  Send them the screenshot and kernel log, and ask if you can open the front fan and cover and send them back only the bad board.  This will break the front warranty sticker, so you must get their permission. 

But at least you could keep mining at 9-ish GH while you wait for the board to be returned and replaced.  The ant won't care if it comes up with only two boards, it will still mine them.  But of course, power down before disconnecting anything or opening 'er up.

Slushpool - nice!

I was hoping that could be worked out. The FAQ says the whole S9 needs to be returned, but it doesn't make sense to do so (to me).

Running on the 2 boards, I'm getting 9.2GH

I'm jumping in with both feet. I have another S9 coming Dec 27-Jan2, Three L3+ this week, and I'm waiting on half the parts to build three ( 8 ) GTX 1070 rigs.

Thanks again for the advice.
