You need to look at the machine status and the kernel log on the machine itself to figure anything out. The pool isnt going to tell you much of anything.

Thought 1 would be you need to give us some more information to help you. Can you see anything on the miner status page? Have you looked into the system logs for problems?

There will be another ramp up in difficulty as well since Bitmain, Avalon, Halong, and Ebang all have new miners coming out in the next few months.
That being said, considering the s7 is still profitable even at high power costs, saying that the s9 will not be profitable in a few months seems pretty silly.
And again, you CANNOT forecast profits in this industry so making assumptions about future profitability is a fools game.

Is it worth to buy L3 miner at current difficulty and expect profit from it
what will be return on investment
It is if you buy it from bitmain and do not support these people trying to resell them for 2-3x what they are worth. The last price I was given was around $1600 from bitmain, yet people are still trying to sell them for more than double that. It is ridiculous. |

Found the problem. Run Linux and all will be well. |

The only thing that doesnt make sense is your question. They are as close to identical as hardware can get.

Without doing any modding or tweaking, what can I do to raise my hash rate?
are u fucking retarded? thats the requirement for raising hashrate Thats an unnecessary response. He is saying he is not getting the expected hash rate he is not asking about how to boost it past normal, hes just trying to get back to a baseline speed. |

While it is normal for one board to be hotter than the others in the S7 the temperature difference shouldnt be that much. Have you disassembled and cleaned the miner?

The vast majority of pools are outside the US jurisdiction and they do not have to report anything to the IRS.

how do you have it connected to the 220? My PDU has C19 plugs, are you using an adapter to convert C19 to 5-15 and plug the kill-a-watt into it? Pics of how you have it setup would be great. I thought the 5-15 plugs were only 110V, so I'm confused how you are plugging the normal Kill-A-Watt into your 220. thanks
C13 to Nema 5-15 > into kill-a-watt > then I have an adapter that is nema 5-15R to c14 that plugs into my PDUs. If I have time ill try to take a picture later. |

PCB temps in the max. 70 c area are good.
PCB temps over 80 c, are not so good and the miner might overheat in 85-95 c area.
The s9 is good to a minimum of 105c on chip temperatures. Earlier models would not shut down due to heat until the chips reached 115c The s9 will run for months at a time at 100c chip temps, its not an issue. |

I have the same issue with my 5 new E9+, that i have recived yesterday. I have 2 E9+ recived in December and they work fine. But with this 5 i have became crazy. Their default ip is 192.168.80.140, I configurate my router's ip as 192.168.80.1, using network scanner i see that when i power on E9 it is visible in network for one minute and then red light becomes to blink and e9 lost. the same issue with all 5 e9. I cant understand what hapens.
While the sticker always says the IP is 80.140 the truth is that they almost never are matched to that setting. The 1500 I purchased were all DHCP |

All of the electricians and HVAC people that come out keep saying to use a Split Unit
Thats because they have no understanding of mining. A mini-split unit is just another type of AC unit, it does nothing special except exchange more heat than a window unit. While it might be slightly more efficient you are still looking at like an $8k (installed) investment into AC to have enough power to keep up with the miners heat output that you currently have, and that leaves no room for expansion. |

I had hashing issues over the summer when intake temps broke 105f

Very odd, The controller(and the Kernel Log of it booting) must boot and begin communication with the PIC before you'll see any boards or begin hashing at all.
S7s depending on firmware do not always show the kernel log properly in the UI. You have to SSH in and look at the physical log file in that case. |

My issue was powering up the controller slightly before the miner. Try unplugging/replugging the controller, or maybe even a software reboot through ssh. It should then find the devices.
This doesnt make sense as the controllers are internal to the miner and power up when you power the hash boards. They cannot be powered up separately without disassembling the miner. |

The miner requires 12v not 240v. You can use 110v PSUs to power them, there is no requirement for 240 on any miner since they all run on 12v dc power....

I use a regular USDM Kill-A-Watt and it works/reads on 220 just fine as long as you dont exceed around 8 amps of current

You said you would be hosting in a data center. If that is the case they should have switch mode PDU's that allow for remote power cycling. I dont know of any crypto DC that would let you put your own power control in like that.
