This is one crazy farm. Never heard of these miners either. Looks like a custom setup.
Guessing they are using Gen1 Bitfury chips ? yep, 55nm and the boards have pico/100TH/bioinfobank markings I have an 8-board gen1 bitfury system (september batch) and it was a great miner for the most part. only downside was that its controlled by an RPi and those dont handle power 'blips'/outtages well and often mess up the SD card's operating system or corrupt the actual SD card. as for the lack of heatsinks, its a good thing. Minimalistic assembly costs, very few parts (just chips in a string design on a sparse PCB) and the resulting product weighs <30% of what it might if there was a metal heatsink I'd be open to investing in some of this hardware (5-10 BTC worth) if someone was hosting them cheap (looking at you, greatnorthdata) |

Using mining calculator at https://tradeblock.com/bitcoin/mining , I am shocked of how much the monthly electricity cost will be for running this full time in California 24/7: $167   45% of the revenue generated in the first month goes toward paying electricity. That's a lot! thats because its california. A lot of places pay <50% of that |

Here's my concerns:
1) apparently the foundation is based in toronto? I heard about it at the CNE today for the first time and they were actively comparing it to bitcoin and had a booth manned by two people who had no idea how to do anything but make people install their app. I asked if coins are pow/pos/premined and it took about 2 minutes for a roundabout answer that it's premine
2) that's $1B of premined currency at fixed value - pretty much identical to how paycoin claimed for months they were fixed at $20/ea but immediately plunged on the open exchanges. You cannot simply create an altcoin and "give" it a $1 billion market cap.
3) how is it non-profit when they control "$1 billion" of money they produced from nothing? If you ask me every treat they sell is 100% profit and should be taxed.

And the buy button just went live, despite the large expense, I wonder how long until they sell out of batch #1?
Good luck to everyone buying these ! Looks like some great gear, but this time around, instead of buying a fancy new miner, I did the following and will HODL.  Lets see which will be the better investment 9 months down the road. This seems like the smart thing to do at the end of the day! As flashy as this hardware is, it's not looking like it is worth the inevitable risks with difficulty rises, and larger scale farm deployment. I will sit this out too, and just purchase coin and HODL. Best of luck to buyers! I bought 0.5w/GH hardware for 1BTC/TH over 6 months ago - its basically paid for itself and still holds the same value on the resale market. This stuff at 2BTC/TH, without power supply, is insanity |

Just curious what you guys envision doing with the old cards from S1's S3's and C1's if sidehack does end up producing an upgrade kit?
Are the old boards pretty much scrap at that point? Do they have resale value?
S1 are probably done for, they bring little profit only to people with dirt cheap electricity. S3 are still good imo. I would run all the S3 i could get my hand on. I guess the S1 extras could be resold to people that want to start little just to learn mining and maybe people who want to run them on free electricity. if you can profit at 1-1.3w/gh, you can pencil mod the boards low enough to cool them with only a fan, no heatsink. connect a bunch of boards with spacers and a pair of 120mm fans and you can still use them to get 40-60GH/board however, the modding takes at least 10min/board (closer to 20 all things considered) |

ALL the 3 PCIE connectors are needed to be connected to power supply on each hash board .... since it is based on serial power solution and there is no DC/DC inside the miner.
Those two statements are unconnected and don't make sense as a justification. If each board can still only be powered by one PSU due to cross-loading, then each board's 3 PCI-E connectors are still connected. While we don't have any high res images to see if we can see tracks, each of the PCI-Es is still in-line and *appears* to be powering the same plain. That agrees with the cross-loading argument which would mean that each PCI-E is the same as the next, meaning the only limitation is maximum load and not because it doesn't have DC/DC. i tend to agree with this. if each board is drawing <400W you could provide that with only 2 cables. my guess is that it does two things: 1) prevents people from burning up cheap 18awg cables (that are limited around 150W) 2) slightly better balance of power distribution so the connector or copper traces dont fail |

so... x27 6pin pcie cables per miner.... im planning to use 3 hp 1200w power supply per miner... but.. 9 cables per power supply .. this seems hard to do... anyone knows where to purchase those 6 pin pcie cables awg 16.. ?  cough. look at my sig |

I know its old. Did not dig really far just when to see klondike post since he is in montreal.  I'm holding onto my current gear pretty tightly, the spondoolies run without oversight for weeks or months at a time |

I posted this elsewhere, but seems relevant to your idea. (figured its better in full context then to just crop it down to the superpeers/keynodes bits) IMO, common sense dictates that in 5 years from now, given virtually unlimited space for blocksize growth (with limitations against spam), the blockchain will be ~2TB and the network will look like this:
- A few dozen 'key nodes' that are located in major datacenters with virtually unlimited fiber bandwidth, lots of storage space, and full verification. Some might be hosted by companies such as google or IBM as demonstration of technical ability or involvement in crytocurrency
- thousands of smaller nodes on home computers or businesses that want their own full backend to handle payments. Its likely that many of these will operate pruned nodes or have limited upload capabilities.
- A few dozen major mining companies and pools. There are a lot of datacenters that are set up in locations with good bandwith and cheap power in the 1-20MW range. Most pooled mining servers are located in major datacenters with high bandwith (ideally alongside a 'key node')
- smaller miners (<50kW) will certainly be pooled mining, which removes the need for downloading full blocks or verifying (you just need to receive the nonce info, hash it, and return any valid solutions)
I 100% guarentee that the future of bitcoin will depend on the 'key nodes' (or 'trusted nodes') principal - where major national/trans-oceanic fiberoptic or satellite hubs throughout the world (such as NY, LA, Toronto, London, Paris, Shanghai, Tokyo, etc) are capable of handling PETABYTES of uploads and downloads and could conceivable handle a virtually unlimited blocksize with state of the art systems. The rest of the network would then act as the broader decentralization and secondary validation.
ps: I like 8MB, doubling every 2 years, but I think 4MB doubling every 3 years would be more acceptable to those fighting for a small blocksize. Anything less than that would be insufficient for global usage |

any estimates on shipping cost?
buying direct, its $40usd/1 or $150usd/5 ($30usd/ea)
presumably you could sell them for something closer to $25usd/stick + ($10usd/1) or ($15usd/5) in the reship. which is pretty small savings
if its cheaper than that though, sign me up for 2-3 sticks

$300 is likely equal to SP3X being breakeven to run with 14 cent electric? Is that about correct? SP31 = 4.7TH @ 3kW (wall). 3kW @ 0.14/kwh = ~$300/month (+/- $30 for different fees and taxes) 4.7TH = 0.047BTC/day = 1.41BTC/month = $>$420 the machine still makes about $120+ profit monthly and at relatively ineeficient settings. (~0.7w/GH as opposed to ~0.55w/GH at 3.0 TH) |

And the auction is over! klondike_bar has won but has not met the reserve. Reserve: '04.50 bitcoins' hashes to 7cef109edbcb3d684877c26905080f2587d8c6114747272661d22854d8135812 I will probably relist these in some time to come. Thanks! probably the reserve scares people off. i barely even bid because i assumed it would be >3BTC. |

altcoins have always reflected overall bitcoin sentiment. The rise happened alongside the 20% BTC price increase
but 400%+ gains are usually brief. It will likely go higher, but i imagine correct to <$4 first

^no way - summer is not a time when hashrate typically increases - the heat in the northern hemisphere limits most operations and is discouraging to home use.
we need to pass $350 before the retired hashrate begins to come online in any major amounts

Could you do some molex to pcie ??
That's a terrible way to hook things up, since that molex connector (I assume you mean the typical 4pin peripheral type) probably isnt capable of more than ~60W. If you really want those, look on ebay - but dont be surprised if they or your MOLEX cables catch fire if you draw >60w Do you make any of the 16awg Y-cables instead of 18awg?
If you still really need them PM me. SRY klondike. no worries - If my supplier could make them Id offer them. But in any case, theres not much reason to use 16AWG unless the 'trunk' PCIe is connected to is <14awg. If its only 16awg (350w peak), the pair of 18awg splits (180w/ea peak) will each handle half without much issue. The added cost and weight isnt worth it for most mining rigs |

absolutely not.
The going rate for hardware that can do 4.5TH/2.5kW is about 1BTC/TH not considering PSUs (and a pair of server-grade gold 1250W PSUs is worth about $300-400)
reasonable pricing is more like:
SP30: $1400-1600
SP31: $1500-1700
Sp35: $1600-1900
these are well-built and can run at the same efficiency 0.5w/gh efficiency as an antminer s5 when tuned to roughly 4TH/2kW
Fantasy prices with impending hashrate boom (sfards/21e/bitfury). Market prices, considering the value of the PSU's and the current difficulty rating. And if you haven't seen, 21 has already been putting hashrate on the network, and we still haven't seen a boom. Funny you mention Bitfury, rumours of their hashrate hitting the market were very premature when we found out their chips hadn't even been ordered. I leave the speculating to the traders, for hardware I rely on facts. Facts are, the price of hardware has not decreased one bit since January. +1. Most attentive miners though the next wave of bitfury/spondoolies/knc/bitmain would flood the market months ago - but hashrate has only gone up about 20% in the last 9 months. Whatever new hardware is added appears to be offset by the removal of inefficient, loud, and/or hot hardware. if BTCUSD decreases, its likely the hashrate will also but that the SP3x will remain profitable anyways. If BTCUSD increases hashrate may skyrocket, but the miner will also increase drastically in value as power cost becomes negligible (once again) |

Do you make any of the 16awg Y-cables instead of 18awg?
unfortunately, 2x16awg wires just wont fit in the crimp prongs for the PCIe. (any anyways, the 2x18awg can handle as much or more than 320W combined) |

.65 btc
Thank you for your bid. This is the current high bid. I am sure there is sufficient interest in these coins that it should go a lot higher then this  0.66 BTC |

HI all, as per title. How much is a sp30 worth? fairmarket value?
1000$ if it is in good condition with all working chips absolutely not. The going rate for hardware that can do 4.5TH/2.5kW is about 1BTC/TH not considering PSUs (and a pair of server-grade gold 1250W PSUs is worth about $300-400) reasonable pricing is more like: SP30: $1400-1600 SP31: $1500-1700 Sp35: $1600-1900 these are well-built and can run at the same efficiency 0.5w/gh efficiency as an antminer s5 when tuned to roughly 4TH/2kW |
