something went badly wrong in his supply chain.
Exactly! Not enough new customers to support payouts to old customers. That's the only supply chain they had. |

If PB miners were a complete scam then he would not have come back on to the forum to show his face.
He only came back because his real identity was revealed, which means he fears the police/lawyers getting involved. Without that revealed you can bet your last satoshi he'd be long gone. |

Any suggestions on what I might be able to do, to get 'em running closer to 1.7TH/s ?
Bump the max voltage to .79 and get it some cold air. |

as long as temperatures dont read much higher than 60C youll be fine i think. fan might get pretty loud though
Yes, the stock fan is quite loud, but it maxes out long before the ASICs register 60C, so unless I do a fan mod the high temp is not the cause of the noise. The heatsinks themselves are barely 50C, so I'm not worried about it at all. |

Nice idea Syke ... I never saw a contract though, not sure there ever was one ... If you got one then please share.
I'm not a lawyer, but I certainly had to have an understanding of contract law when I studied management all those years ago.
Even today contracts are a normal part of my business life.
In a nutshell that is
Offer
Acceptance
Consideration
Certainty
Of course there's no "official" contract. This was a "business" run by a novice with no understanding of how to run a legitimate business. But being the wise scammer he is, he quietly changed the details and deleted posts to hide the conditions promsied. https://bitcointalk.org/index.php?topic=418183.msg7692696#msg76926961. Of course we are hashing, otherwise we would be paying our users out of our own pockets and that would eventually make us bankrupt. We are here to succeed and have paid out our customers on time since our launch.
2. There are no mining pool fees to the customer. We cover our own mining fees from our pool workers which the customer will never have to see.
Instead, the customer is payed based on this fixed formula, taken right from our PHP script:
$per24 = ($totalHashingPower * 25 / $difficulty) * (60 * 60 * 24 * 65535 * pow(10,6) / pow(2,48));
This formula is standard with all Bitcoin Profit Calculators. Our users do not mine directly with our hardware -- the advantage of this is that we are capable of insuring them during any downtime or performance reductions. PB Mining guarantees a fixed rate of hash power at 100% efficiency -- a luxury you will not find anywhere else.
Emphasis added. |

What is the potential for damage by running these in an hot environment? Where I work, our server room is pretty damn hot. Right now I run my miners outside my home. Its summer in Australia and its pretty brutal. My miners see 35 - 40c days and hot nights.
Should I be concerned running something like an S5 in this environment?
I haven't seen any problems overclocking mine to 400M in a 40C room. |

As long as he pays something he is not reneging on your contract
Not true. Contracts were sold with a specific payout formula. He is no longer adhering to the original payout formula, therefore he is violating the contracts. |

Testing out a theory that board temps <60C is required for stable performance.
Have mine overclocked to 375 and running @ 55-58C for about 6 hours now with no problems.
Tinkering and testing continues...
Sissy. 375 @ 68C for 30 hrs and counting... |

What kind of ROI time are we talking about?
Very rough numbers because everything changes, $150/mo income, $50/mo hosting, $500 purchase price = 5 months with static difficulty, 6 months if the difficulty rises slowly. |

Im just wondering with these all new miners coming out, is there any money to be made via mining anymore?
Definitely, but it requires low electricity/hosting costs. |
|
|
|
No. I am not a thief.
Where have I heard that before? Oh yeah,  |
|
|
|
I don't need to explain that.
Yes, you do. For the last few weeks you have been stealing from your customers. |

You have 3 options.
1. Buy Bitmain miners
2. Buy Spondoolies miners
3. Spend $10,000,000 USD to build your own.
I'm guessing you can't affort option #3, so spend what little money you do have on Bitmain and Spondoolies.

15A circuit, 1300W PSU, 2 miners living in perfect harmony:
Ebony (Overclocked S5): 1240 GH/s
Ivory (Underclocked SP20): 1140 GH/s
Each miner is drawing 700 W (+/- 2%) at the wall.
|

|

Im measuring at the PSU, not at the wall. and by measure, I only know what the SP20 tells me (i set it to 150W/cable) and whether the PSU trips (612.5W 12V rail, seems to trip at 625W+). Right now the SP20 is at 10% fan, 18/52/47 temps, and 1.195TH. noise is about the same as my S5 at 5V fan power, 56/62 temps, and 1.23TH
update: pushed the Sp20 to 8% fan and 155W per connector. PSU seems steady so far and volume is about the same as the S5. 50/55C exhaust on it with 1.21TH. Both peices of hardware are excellent and capable of similar specs when running at 1.2TH
I'm going to tune both S5 and SP20 to 700 watts each, and see what performance they get. |
|
|
|
The SP20 is about the same volume at ~10% fan speed and can drive about 1.25TH/600W in the same ambient settings.
I dont have a killawatt
I haven't seen anyone get the SP20 that good. It's more like 650-700 watts for 1.2 TH/s. |

So these ones are setup to use DHCP out of the box instead of static 192.168.1.whatever the old ones were?
Yes, it comes preconfigured to grab DHCP. |

Anybody have 2 running on a single EVGA 1300 G2? Should work but wondering what your results have been.
Haven't tried, but the numbers look fine. You should get both at least at stock speeds, maybe even a little overclocking. |

in other words looks like BFL wins? (or am I missing something)
It to me looks like BFL will wind down as a company ..declare bankruptcy and being a corporation the principal investors will be protected and walk
The FTC was not able to completely shutdown BFL. Other than that, the FTC has already won 4 major victories: 1. Shutdown BFL for long enough that other companies have far superior products available for immediate purchase. 2. BFL cannot take pre-orders ever again. 3. BFL must provide prompt refunds to anyone who asks. 4. FTC's lawsuit against BFL will continue. BFL's product is uncompetitive. They have no way to fund new products. BFL is finished. Celebrate! |

Speaking of power at the wall. Has anyone done any tests to see what power is being pulled at the wall? And if so, what kind of 80 Plus rating and wattage does your PSU have. Just wondering at what efficiency and % load that Bitmain got 590W at the wall?
My review is at https://bitcointalk.org/index.php?topic=908126.0. My 750W Bronze rated PSU has plenty of power for maximum overclocking. |
