Just for giggles, can you plug the controller board into a power supply and see if any of the chips get hot or warm? I had a S15 come in dead and it turned out the CPU chip was getting extremely hot. Traced it down to damage in one of the I2C lines, I think what happens is that the boards I2C goes straight to the CPU without any buffers or schmidt triggers. And when the line causes the CPU to go bad you have a short in the chip that gets the CPU very hot and eventually fails.
Only reason I figured this out was because KNC Titans had the same problem with the serial lines from the FPGA directly driving the hashing chips. A surge or spark or oddness would blow up the line, and the FPGA would get hot and eventually fail/burn out.

I always celebrated December 26th as McArthur day.
The day when everyone wakes up, goes to the mall, and says "I SHALL RETURN!!!!"

What a weird dream: Someone came up to me, tapped my pocket with something, and stole one of my bitcoins from my phone. Like it made the phone do a transfer by itself. Then they ran off into the crowd.
I spent the rest of the dream trying to figure out how it was done. Software debuggers, RFID tools, wireless hacking things, you name it.
Odd

Naah, the survey should be:
The world is flat
The world is hollow
That separates the men from the boys.
if the world/universe is a "hologram", would this count as a flat or hollow? Blasphemer! We should smite you or something like that :-) Ok though, add a third option world is a hologram. |

Good. The number of systems I have fixed due to burned.... stuff.... is something that's in the back of my mind. Still, I'd say start by running it for a few weeks to get the hand of it to establish a baseline, then go from there. Would probably be worth it to enable high efficiency mode to reduce heat, wear, and minimize power expenses.

I'd say if you just got it, start by configuring it to mine over to slushpool and watch it for a few days.
If running on a 110 volt outlet (not a good idea IMO) keep a close eye on the power plug, cord, and the circuit breaker (use a finger to feel if the breaker is warm) to make sure your home wiring is not getting hot. Don't run it on an extension cord. Keep an ear out for the fans, listen for unusual sounds that might indicate a bearing failure (used miners can have this issue). Use your nose to see if you smell any wiring burning/melting/whatever.
And keep an eye on the hash rate: You probably don't need to reboot it daily but let it run and see.
I run mine as a hobby miner/test bed for weeks without rebooting, stock firmware. With two boards enabled, it mines at a solid 9gh as reported on Slush and pulls 1,000 watts from the wall as measured by a P4 Watt-meter. That is about as much as I will put on a household 15amp 110 volt circuit. Once you have a good idea what it does, then start fiddling with things like new firmware, low power mode, and the like (if your firmware supports low power mode turn that on).

Flat Earth!  People are hopeless. The Earth is *not* flat. The Earth is hollow. |

True: I'm running my reference one with two boards enabled so I can run it on a 120 volt power line. Two boards using stock firmware results in about 9th speed at slushpool with 1,000 watts being pulled at the power plug. Which oddly enough seems to be about the same as running three boards in "low power mode". Go figure.

Darn. I'd be happy to post em on imgur and link here for you. PM me an email addy if you would like and thanks for posting this.

Pictures of this would be interesting. Any evidence of overheating on the power bus bars?

Oh great. It's going to go back to 9000 again and we'll be bitching about that.
Again.

Seriously. Fuck the rat race, if you can.
You only have one life to live. Don't spend it being a slave, even if it means giving up certain comforts.
If you can't get out of it now, set yourself up so you can later.
If I walked into a company and saw this shit I'd turn around and walk out. No salary/slave wage is worth that shit. |

Eh, everyone's just buying Lambos for their friends, and thus need to cash in coins.

My it's so nice to have one's store of wealth controlled by people with agendas that may not line up with yours. Oh wait, there's bitcoin :-) * people=rotters |

That was fucking funny ass shit, actually it may be the only time I've ever laughed when Conan was involved.
Hunter is one of those people I really aspire to be like.... |

Both parties believe they're in a much stronger position than before so they're both going to rebuff whatever the other suggests.
The SNP have mixed up the desire for independence with not being Labour or Conservative which is probably a much bigger factor in most of the votes for them.
I'd love it if Scotland did tell England to piss off but it's a very lengthy shot indeed.
I doubt the Tories would let Scotland leave. They need that oil to subsidize their agenda. It's the way of the rotter.... |

I strongly believe that England will come out of this as the winner.
They can now start to build an alternative free trade area witch will be muck bigger than the EU, Just like they once created EFTA.
 On the positive side Corbyn will "never lead another general election campaign". Right......... |

People are snapping them up as collectors items. :-) Just wait till the Brit bank "devalues" it to "save the Union".  |
