Att köra miners eller farm med sol..njah. Jag testade 200w panel och mppt plus med 340ah batteri...Ca hälften av strömmen kommer från panel och hälften väguttag. Endå blir kw priset högt plus paneler bör vara enorma emot vad som krävs och på tal om batteri..

Hi guys.
Now, i know this has nothing to do with the problem but im S3 user and i been using one s3 to testing with solar. So, i have 2 solar panels with mppt controller and 2 170Ah batteries. So i take two cables from the controller and connect them to S3, one cable each side. And from the wall i have two old psu as well connected to those two other connections. So i use all those 4 ports. With stock speed the S3 uses about 450w from the wall but with the solar On i take from the wall around 280w...isch. I lower the speed down to 175mhz and take from wall around 128w

But while i tested the psu on S7 and it worked well??? I have a different fan on the psu also so it is alot more cooler than before.

Hi guys.
Well you not really the only one. I had some xx but after restart most of the time it goes well. How ever IF i used the stock firmware. After update i got even more weird stuff going on.
My psu is antminer 1600w so no problems there. I even use another fan on it to keep it real cool.
But i just been talking to support about my last weird thing... After like two days of using the s9 like to get slower and slower... ? wtf

Temp is not a problem right now. As when the temp was at around 90C the s9 pushed on really well.. Untill now

Also one hash board gets pretty much hw unlike the other two. I changed the port on controller and got more better results but now again.. back where i was before :S

A update about my S9.
There is 4 ports on controller to connect to blades and there is 3 of them. Been talking alot with Bitmain support.... So i reconnect the wire's and because the last blade/port..gave me high rw error. So i rewire them. And how big different there was. It seem's not only a bad value gives you error's but also port from controller..
How ever, bitmain told me i could overclock it to come up 14th/s but i would loose warranty. As i told them, this was not what i wanted to hear. Ofcause.
But later mail they told that it would be alright if i overclock So i try to 650mhz. But to my surprice i didnt get those 14Th/s :S
So now, i use a fan to blow on the controller also to keep it cool.

Well what i been "testing" on my S9 so yes. It does work.. But when you do write your miner ip and click OK just press the voltage and press SET VOLT. Then it ask if u sure just click ok.... DO not restart or press anything else on S9...!!

On my B2 s9 i been playing around with the anttool..And set the voltage and also try many mhz. So far i been seen pretty big different when i set the mhz at 587mhz and voltage at 0717. I got abit better hash around 12th/s and rw was pretty low on two of the blades.. But one had abit more.

One thing i dont understand is that Why does the controller have 4 ports for blades when there is only 3??
And other thing is...Been talking alot with Bitmain support and they told me to take all out and check burn spots So i did.. nothing there..
But then i change places with the " first blade  and the middle" Even so, cause i believed there was some wrong with the blade, the other blade from middle shows higher rw error.
Could there be some wrong with the controller??

Hi guys.
I do see some else has problems with the s9. I have been talking with Bitmain support about my problem.. First of my fan at front burned up so i putt a new on.. This fan's seem to be JBL fans if i not remember wrong and they do have lower rpm than the other Delta fan.
How ever...Bitmain saying that i should take out my hashbord's and check all... And also the controller.
Now, what i believe is that the controller goes pretty hot aswell and there for i get some high errors.. Well high to my eyes.. My S7 work's like charm..never have hw errors at all so..

Anyway i do belive addind another fan on to controller should give some results..? Or what you guys think?

There is 4 ports on the controller to connect to hashboards. If some port is "bad" can i then connect to the 4'th port???

Thank you

Hi guys. I'm pretty new to this but been trying. Thing is I got my self a s7 from a guy who used it like few days...anyways. It been working real fine and so but for some reason one the blades is way high temperature than the others. Like 20c more. What's going on? Has some one else this or can some one help me out what can I do?
Thank you.
