Ok thanks guys

I will keep messing with it.

Expect more questions to come about it.

I just posted in another thread a different issue now.

Does not seem to want to stay connected to the net. It will connect to hash for about 15 seconds then stop.

Yeah 1 board is down.

I would reset my freq from 700 to 675 set my fans to 50% boot.

Wait a bit  and then see if I was at hash of 4600 fan speed of 3600-3800 rpm check error rate under .0050 lastly check my temps under 63

Looks like I am now having the same problem with my miner.

How much time should you wait with lower freq?

And other things that can be done if this does not correct the issue?

Thanks

Its just to see if its the PSU being an issue. If you reboot with low freq after a power cycle and it still does not work, then barring something obvious missed, a board is probably having some issues.


Yes psu if running at full speed slowly kills itself or ages itself.

So if turned off and back on it may never reach the speed it did.

A lower freq will allow all boards to fire up

It that works. Say 700 down to 650 wait turn off after an hour . Then try 675.

Thanks Philipma 1957 and Virosa. I turned off and tuned on the miner and now all is ok.
Thanks again.

Hi,
Yesterday my S7 was working normally (4.750 Th/s). Connection to Internet was interrupted and I shut down the miner for several hours. Now (when I turned on it again) is working only 3.200 Th/s. Why?... What to do?
Thanks

Give us a screenshot of your status page. One board is probably not running. Whether is dead or not is up to see.
