Pretty cool. It looks like the you can plug the input into the output so you can do 2 units back-to-back and get 480V to play with.  Three units would give you 960V! 960V!!! And the sickest death of all time. Seriously people, don't get shocked with 240V or more. Instant death is to put it lightly. There's a reason US went with 120V, and while I usually don't agree with lowest common stuff I can see why we went with it. When I was young I walked away with a 120V shock burned but OK. If I was younger and shocked with 240V or more I'd be dead. Dead. Please don't post things when you're not 100% sure of what you're saying. Voltage doesn't kill, amperage does. FYI USA is 240v. It's simply a different "type" of 240v than Europe. I'd even go as far as saying 120v is MORE dangerous than 240v or higher. Getting stuck on live 120v wires can be worse because the low voltage doesn't "blow" you away, you can lose muscle control and stay clamped to the wire until you fry. Higher voltages will have a tendency to knock you back or off the wires more easily. |

Fast update: Might have a Titan controller and dead units coming in, we'll see. If so I'll post pictures and updates on those, will be interesting to see what they look like. ...
Judging by the pictures you've taken of neptunes, you'd be appalled at how similar every thing is with essentially the same exact placements and design (except for the low binned' chip). Yep, pretty much the same. Power supplies are 40A on Titans instead of 50A like Neptunes. Stupid KFC...  Loving the progress, lightfoot. Keep it up.  |

Cool, and it's only $200 and inherently lossy.
Not to mention Chinese. Very Chinese. Its cheaper if you click around found exact same thing for $80 and $60 shipping. Still cheaper then wiring 240 at your home, or if you live somewhere where you can't get 240 volt.
No, it isn't cheaper, and it won't give you any of the benefits of running proper 240v besides getting the bitmain PSU to power on. It's a very bad idea for mining. |

Good job, Aluz!  |

Batch 8 / DPS-2000BB efficiency measurements teaser shot:  Waiting on a 500A shunt to finish the DC draw measurements but I hope to get the WallJ/TH numbers up soon. I will say this particular Batch 8 hits 5TH/s with no drama. And... it keeps the DPS-2000BB cool w/ exhaust at the same time  Nice! Looking forward to your results. How are you getting 5TH? Mine won't overclock for shit, in fact they can't even reach advertised speed. Have you found a way to increase voltage delivered to the chips on B8? So far all I've done is increase the clockspeed through the web interface! I haven't looked at chip/chain level voltage at all, even to measure it. Luck? Very lucky. Mind posting a screenshot of it after running for a few hours at ~5TH/s? |

Don't want to pull my rigs from Kano, but I'll rent a bit of hash to join the party. Good luck, all! |

And they figure they owe you and everyone else shit all. What a fucking horrible shitty company they are. If any normal business acted like bitmain does, they'd be bankrupt with the quickness. Luckily for bitmain, they have a (hopefully temporary) monopoly for the home miner's market, and they make money printing machines so they don't actually need customers. We're just there to reduce the risk they take in developing hardware. All they're good at is making decent hardware and shipping. Everything else is a complete shit show. |

I've always updated my antminers with Firefox. No need for Chrome. I guarantee he's getting an error because he's trying to extract the file instead of just flashing it as downloaded.
I don't suggest updating the miners, though. Just set a manual fan speed with whatever firmware you miner shipped with.

My miners arrived, and got stuck at the customs  . They are asking for the invoice (proof of payment) but i still havent heard from Bitmain. I opened a ticket on Friday. I called in USA support, talked about 10min and no help from that guy!!! What should i do guys? You should have received an email with proof of payment that shows bitcoin converted into USD shortly after you purchased them. Simply print it and show it to them. EDIT: I have noticed my most recent invoice from BITMAIN only shows BTC for payment and no USD conversion. Maybe the BTC will be sufficient. I cant give them the BTC invoice, they need the dollar invoice. Fuuuu im screwed Photoshop the conversion to usd at time of purchase on the email. |

Can you idiots stop bumping this scam thread up and giving them more attention? It's been established, it's a scam, move along. Stop necroing dead threads.

bitminerpro_S3
Do you think that was actually an S3?
Wow, well done if it was. Gives me hope.
Edit: low diff block. lets hope for many more.
The last 3 blocks found by bitminerpro were from S3s. ~11 S3s are just as likely to find a block as 1 S7. It isn't the speed of the individual machine, it's the overall total hashrate. |

Your PSU looks like a cancer ridden 2 pack-a-day smoker on his death bed. Are you sure it's still working properly?

Cool that you're saving money, but why are you nervous about your power use? They don't give a damn what you use it for so long as you pay your bill. The more the merrier, in their opinion. They'd be happy to have you max your service out. |

So this question is for the hardware/psu gurus. I'm powering a Neptune heater in my house with server PSUs that don't have native 5v output. I'm using this to step 12v down to 5v to power the KNC controller. I ordered it a little quickly, and didn't notice that in its specifications ripple is listed as 200mv which is insanely high compared to ATX specifications of 50mv max on the 5v rail. My question is, how dangerous for the controller is this? Am I looking at imminent death? How would I go about smoothing out the ripple to acceptable levels? I do have server PSUs with native 5v output, but they're less convenient for in house use. I guess I should possibly just use one of them with a single cube to take advantage of it's clean 5v output. |

Another block!?  Good job oblvnxknight! |

Why do you guys use manual difficulty?
Anyways, the proper way to set difficulty is hashrate / 1.4. So for a 4860gh.s S7, the ideal difficulty would be 3471.
