I started using BFGMiner with two BFL SC Singles. The actual hashrate just doesn't seem to add up:  49 GH/s literally going nowhere.  Its not the singles. Its 50BTC. See the AS number around 4500... it is having trouble submitting to 50btc. I have had similar problems - high latency to the stratum server especially if you are in the US. I have had MUCH better success mining it at: pool-us.50btc.com:3333 Try that! Rob +1 Try eclipsemc.com or eligius.st, both work well with BFLs. |

Well why on earth would anyone new get into Bitcoin? The value prop is disappearing. The mining goldrush is ending. There is, however, still strong reasons to get involved in bitcoin as a value store, and method of value transfer. If mining disappears, so will the bitcoins...It will take forever to confirm even the smallest transaction. So if you plan to store value in bitcoins you better start mining. |

BOOM!
At this rate, my BFL asics will be unprofitable by the end of the year.
Yeah, my mini rig btc per day just went to ~ BTC5 from BTC6.4 That is huge. Next estimate is 86M, crazy numbers...That would put GPUs and FPGAs to rest. Forget Avalons and BFL singles..., you need bitfury, cheap, and lots of them... Avalons making ~ BTC4 a week now. |

As of right now, none of the settings will take affect, but they will be stored. I will be completing the backend support for all of the options during the week and should have everything done by the weekend.
Thanks wizkid. Setting the initial diff for different workers would be very beneficial if one wants to run multiple workers on the same payment address. I've tried it yesterday, but my second worker (when the first worker was running at diff 128) kept going back and forth between 1-128 diff, creating a lot of havoc. Individual workers were stable, chugging along at 128 diff, but as soon as I added an additional worker, problems started, creating lots of stales, drops in hash rates etc. I've sent you PM with details. |

when the temperature reached 86 C on one BFL device, that device was not disabled. Do I have to setup any other "auto" parameters for temp-cutoff to work?
After a careful review of the code in question: - --temp-cutoff acts when the temperature exceeds the argument. This is how BFGMiner/cgminer have always interpreted the value, so this is a documentation error.
- While a device is resting, the hardware error counter continually increments. This is a regression in 3.1.4 (older versions worked correctly).
- It works for me, with the above in mind.
Thanks Luke. I noticed it is working when it hits around 89...with parameter set to 86. |

connected to stratum.mining.eligius.st with diff 128 with stratum
am I using GBT or stratum?
used "no-stratum" option to get to gbt. By default the pool redirects to stratum when connecting to gbt host/port. I run it for a while but it looks like gbt drops my hash rates to a crawl. Not sure why, Switched back to stratum. |

Needs some editing... here let me try. We are going to refund everyone sorry we fucked up badly. - Yifu Pretty much. All the talk about security is just an excuse for failure to deliver. I don't buy it. If someone wanted to harm them or extort money and they did not pay, they would be swimming with the fishes now... Well, maybe not Yifu, he will probably just float. |

Hello,
We`ve ordered a miner from BFL on 20th May and we paid for express delivery. To this date, the status of the order is still Processing, which means it is not yet assembled and this is a period of more than 2 months.
Can anybody share an opinion on the topic ? How long does it take on average to go to status Assembled/Shipped ?
If history is any indication, I would hazard to guess you might receive your May 2013 order no later than end of Q1 2014. With any luck by Christmas 2013. Probably sooner, I say end of the year. Now they are just assembling the products, providing support and sales. All the try/fail/try again engineering stuff is behind them. |

Untrusting of escrow, seems legit. I also have a unicorn for sale without escrow.
I've done business and met in person people from this forum. I never done escrow as a buyer or seller. Why don't you order from BFL or Avalon and ask for an escrow see how that goes. You're not BFL or Avalon, you're just some guy on a forum. I don't know who you are, where you are, what you are. BFL and Avalon are rather harder to make disappear. Trust me. If you deal with me, you'll know who I am and I'll know who you are. https://bitcointalk.org/index.php?action=trust;u=51626Read my OP. 5 days left in this auction. |

Yeah, would have John K. hold, get a tracking # and if there were any serious problems with the unit (like he send a shipment of bricks), I would video myself opening the box as proof to send to John K for any disputes.
I prefer we meet in person. If you want me to ship, you have to pay in full before I ship. |

As long as escrow with John K. acceptable, I will start you off with a 300 BTC bid.
I don't know John K. Never met him. No escrow service. Why escrow? so that you can mine with it and then say that you don't like how BFL installed the power supplies or the unit is damaged because one screw is missing. BTW, this case was cut by BFL on the back side to fit the two PSUs, bottom half is hanging by one bracket on right. Very unprofessional if you ask me. Internal hub was glued to the case, it came off. It is hanging in the case on the USB wires from the boards. Fixed two fans that were not spinning because the wires came loose after they slammed the the fans into the case. Soldered all fan wires together on the right side. All fan are working now. Want to know more? Ask. Bid not accepted. You want to bid, accept my terms in the OP. |

Luke, is bfgminer throttling work based on BFL device temperature?
I'm seeing 85-86C on one BFL device and was wondering if bfgminer has a logic to throttle work, sort of like GPU
temp control. The --temp-* options work fine for FPGAs/ASICs (with temperature support). Thanks Luke. I've tried "temp-cutoff" : "86", "temp-target" : "79", "temp-overheat" : "82", "temp-hysteresis" : "3", but when the temperature reached 86 C on one BFL device, that device was not disabled. Do I have to setup any other "auto" parameters for temp-cutoff to work? |

Just for fun (as mining profitability calculators are not by any means the word of god, as it were)
The most expensive mining.thegenesisblock.com thinks you should be able to sell BFL minirig for is: BTC429.941
This would yield, they surmise, a lifetime profit of BTC0.000616
I don't think the network hash rate will increase exponentially as these calculators suggest. You just cannot keep plugging new equipment to existing power network and expect them to work. Even with these BFL minirigs you simply cannot run them at home anymore. They need two 15A dedicated circuits and proper cooling. Professional hosting warehouse is what they need. So expecting an exponential growth is probably a wrong assumption. But then again, I'm the seller so I'm biased. Right now, they make BTC6.4/day |

Ya checked blockchain.info their posted balance for me is way off vs what fulled sync Bitcoin.Qt says
You probably have many addresses in your wallet. So you'd need to add balances of each address from blockchain.info to get the total balance of your wallet. |

...
On top of that, the chips get 3.2 watts per GH/s...3200w for the 1TH/s. Let's shoot for a normal-(ish) $0.15 per kWh price (which would probably be quite high for a datacenter), which would put the cost per month at $345, or $4147 a year.
Except, 480 GH/s minirig with 128 chips pulls 2000W from the wall. So 1TH/s would require 40A circuit. And the electric bill for 1TH/s would be north of $5K/year |
