If your back fan is reading only 800 rpm that means its dead. The RPM reading is from the front intake fan spinning the back exhaust fan. If both fans are reading that low, it might be a power problem on the controller board itself.

Sound is literally the least important aspect of miner hardware, especially to a company that would like to sell a large quantity of units. One decent sized farm places single orders most likely equal to an entire years worth of solo purchases from home users. There is no money to be made
What matters is price, efficiency, 30/60/90 day failure rates, and the ability to buy in bulk with reasonable shipping times.
Also, Syan is still saying all the wrong things if they are in fact a legit company. They offer a FIVE YEAR warranty on mining gear? How many color guard troops waving red flags does it take to clue people in?

You are posting up a third party site when everyone knows you should only buy your miners direct from the company that produces them. Otherwise you are paying a markup and most likely will not have the ability to RMA them since they were not purchased in your name.

If you have $100k to spend and your best resource is asking anonymous people on a forum what you should do, maybe this isnt where you should be spending your money.

In the advanced settings there is a tab up top called Network.
In that the first sub tab will be Interfaces.
Click edit on the interfaces and it should bring you to a screen that has a detailed breakdown of the settings used for networking.

never reflash
Unless gear is dead
Phil you really need to stop telling people this. Firmware updates fix many issues on these machines. I have literally flashed THOUSANDS without killing a controller board. Claiming that its dangerous is just flat out wrong. People need to not be stupid and use the proper firmware for their machines but other than that there is no danger. |

I use 3 phase all the way to the PDU xy xz yz As in the PDU's have 3-phase line-in and split it off to 3 banks of single phase pairs inside of the PDU's? That would be pretty damn handy... Yes it is 3 phase all the way down into the PDU. Its split internally in each PDU xy xz yz. Each leg has its own 20 amp breaker on the PDU. |

The S9 isn't best in class - Bitfury was showing similar efficiency to what Syan is claiming on their demo
Bitmain can also hit that efficiency with their chips and have shown it. I dont get how you can argue the S9 is not best in class right now by the numbers. Show me a bitfury miner I can purchase right now? Show me ANYONE thats ever seen a Syan? BW couldnt match efficiency in a retail product, neither could Canaan, neither could Bitfury, neither could Ebang....the list goes on. |

but after their disgusting step on banning almost everything related to bitcoins
You sound pretty misinformed since they, you know, didnt ban anything to do with the bitcoin network. They shut down the exchanges so they could properly regulate them. |

If you jumped the proper pins and it is not turning on your poor psu has bit the dust.

Not all surge protectors are created equally. The lower end cheap ones only allow for a small variance before tripping. Also most basic ones are only rated for 10-15 amps. That is 1100w-1650w with 110v power.
If yours are only rated at 10 amps you are right at the edge of usability with no spikes. Add another surge protector and you should be good.

Why would you people use Windows on a board like this? Every one of these i have built with PiMP has booted flawlessly the first time with 12 cards. Its one of the easiest mining boards I have worked with. Everything is good right out of the box.

OK. We installed Putty on our PC and accessed the RPi Root User.
When we ping google.com, we get: "ping: bad address 'google.com'"
When we ping an IP that is pingable in a CMD prompt on our Windows machine, we get: "ping: sendto: Network unreachable'"
Any ideas now?
Thanks.
Sounds like you have messed up network settings. We wont be able to help with that without seeing what you have entered. Can you take a screenshot of your network settings? Also you can telnet into an avalon RPi with no password, you cant ssh into it until you set a password on the web gui |

3 phase distribution that feeds a single-phase (or a North American "split phase") setup generally uses a transformer to convert - which renders the "balance the phases" issue moot.
I use 3 phase all the way to the PDU xy xz yz Whats the point of having 3 phase power if you just have to use extra hardware to convert it? |

D3 retail price = $1450 USD
Your price = $3700 USD
what a deal!

Yea thats exactly what i found and posted about earlier in this thread. |

Do you have any specific info to back this allegation?
This is interesting because GMO Internet is actually quite big company and has been around making IT product for a while.
No I dont ever reveal sources. You are more than welcome to be skeptical, it matters not to me. I know what I know. |

Um, we don't do 3-phase calcs because the PSU's are fed single-phase so only single-phase calculations apply. Ja large locations have incoming 3-phase and some of that will feed 3-phase motors and or A/C but thass it. All else is split off as 1-phase.
This for sure. You dont make any changes to your calculations between the two. At the end of the day you are still feeding single phase power to an individual unit. You will still only be able to put the same amount of miners on a circuit. Also as T-Gee05 said, it is incredibly important to balance the draw across the phases if you are running 3 phase power. |
