what freq is your s-7 set to?

if at stock simply lower the freq  if stock is 650 go to 550  if it overheats after the down clock let us know.

ps it would help to know what you use for a psu

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

A picture of your layout would be helpful. PSUs too close (and 'close' is actually quite far) to intakes or exhausts have their airflow ruined.

Many issues now friends Smiley Smiley so great to have you guys back Smiley Smiley MMuch love from the "middle ranks" to the upper ranks of the sess pool known as BTC Cheesy



Ok so unit 1 (the unit we are discussing) Is running stock psu. I am changing freq now. Will report back! Smiley


Ok so unit 2 having massive problems. All boards are hashing. Will start running at 4.7th then will drop to like 1.3-2 and jsust sit there. Everything says hashing.



I have the PSU's sitting on top of the units I am using bitmain psu's. I had them on top before in my old place, but i had them next to the deck breezeway so much more air. Pretty sure dogie is spot on.


How do I move my psu's further? Bitmains cords are so fking short. Help??

I dont really think there would be an issue with the default setup. Issues like that would probably be related to the a psu being crap, built with third tier components. If the PSU intake is extremely hot, then maybe it would be a temporary heat issues, but i think the S7 would overheat before the PSU.

You can always get a laser thermometer and check, if you think its a conditional issue.

What is heat in mining area?   If you have two S7's, 2 PSU's, all in summer it could be hot in some places.   So really need to know more right now all we can do is give general ideas of help.

Are you able to take picture of area? Saying "I have the PSU's sitting on top of the units I am using bitmain psu's" could have so many setup's that is a very broad description.

So need more info and temp's of area.  Even screenshot of status screen of miner slowing down might help.
