Has anyone measured how much power an Antminer at 400Mhz consumes?
3 x O/C Ants each with their own 850W Bronze PSU draws about 1280W at the wall. So that's about 425W each. Im actually running 3 overclocked to 387.5MHz on a AX1200 gold PSU. however, i think that 2 of them need to be tweaked to 375 because the hw error rates are a tad high and it would ease the load on the psu slightly |

But can I plug that into a USB port-and-only a USB port and be off and running?
You plug it in a USB port and power 70W from a PC PSU molex connector. That's an awful lot of words for 'no'  Yeah but neither does this by looking at intron's photo.  I think he's overclocking it. The base configuration: Power requirement: 2-2.5A to get full speed,
:shouldn't need it. Again, it's still well outside USB2 and even USB3 spec, but not outside the norm for powered USB hubs (and I'm just talking about generic ones made to be able to charge tablets and the like that already like soaking up 2A or just refuse to charge, not the made-for-miners USB hubs). so you are talking about 1 device per hard-to-find/expensive USB hub and charger? That is insane - why on earth would you not opt for a 60GH single board that acts the same wa and could be powered from a PCIe cable or a molex thats alreay inside your PC? |

I suspect...
S1 in stock because they are probably liquidating their old farm.
I agree ... I have received recent Ants that had been used ... removing the fans showed a lot of dust, and I had to clean them ... but they hash away and work fine, so I'm happy. grab an air duster can - youll be able to blow away all the dust and other crud with minimal work. Also works well from desktop/GPU/laptop systems to clear out the dust that accumulates over weeks or months (most of my gpu heatsinks released a small cloud of dust when blasted) |

You can get 1TH for about $3k, $4k at the most.
From someone who just took the plunge it cost me $3500 and I'm mining about 10% more than the mining calculator predicted and I'll break even in about 3 weeks.
This. I keep reading these "mining is not profitable" threads that pop up quite often and it's simply not the case. Mining is hugely profitable given a high enough hashrate on readily available equipment. If it weren't profitable, you wouldn't be seeing these super large private mining data centers popping up. I honestly think people want to keep spreading this FUD to keep people out of mining and make more money for themselves. Yeah great advice. Mining is profitable everyone ! Keep buying hardware. Give money to ASIC manufacturers. They sell you hardware to make you rich of course. when you invent a quality product, i expect you to sell it to me at cost. Why would i want you to make a profit off me? its called capilaism. people buy machines at the posted price. some of the prices are low enough that a miner can get a tidy profit. other prices, particularly pre-orders, are overpriced and a bad investment. I don't understand why everyone who says mining isnt profitable assumes it is a blanket statement as though an antminer is equally bad investment to a BFL product |

right now, the collective is on 'pause' while i sort out some of my own hardware and evaluate the temperature and noise limits of the location. I will be running over 7kW of my own equipment by mid-April and am still not 100% sure how much cooling the AC can handle in summer (10kW? 18kW? more?) so am hesitant to start adding other equipment if capacity is limited. I'm hoping to change this very soon, but the concerpt was created with bitcoin>$800 in mind so that equipment costs would make a few kW of power use very expensive hardware-wise. now, 1kW can be almost be fully used by <2BTC of antminer equipment and this drastically affects the scalability. Even if this space is not suitable for a collective and/or >15kW of power draw - I am still aiming to move to a much larger (at least 60kW) location later in 2014. I might still do some hosting in the near future, but the learning experience is causing me to think the current location will not be large enough to do what I originally planned for the collective (which was to have 20kW+ capacity using machines more valuable then they are at the moment) regards :Luke ps: here is the state of the setup right now - 18kW of available power could be easily fit into 1-2 shelving units but I am beginning to think it would not be difficult for me to fill them almost exclusinvely with my own equipment, and even if hosting only 1-3 other people would really be able to share the space  There are 5 antminers on the shelf, 1 more on the top shelf, 4 more in the plastic crates at the side, and I will be adding 4 more on wednesday for a total of 3TH When the Bitmain S2 arrives I will be drawing about 7kW for >4TH of hashing power. That will give me a better idea on the limitations and capabilities of the system |

^the fact is that if its someone else's chip, the costs of production will be much higher then with a custom actm chip. We are talking about $1/5GH on a custom wafer and packaging (with upfront R&D that the IPO apparently funded?) verses $1/1GH if buying someone else's chips

*smirk* yup - sure are  $1750 bitfury (~17BTC) has made over 18BTC already and is still running at 260GH any antminer bought at >3BTC has already broken even all my other antminers will break even by mid august at the lastest my antminer S2 should pay off no later than october at that point, I will still have >4TH of paid-for equipment mining 'free' by the end of 2014. If bitcoin is still around (i think it will) and value goes up (it will if it stays around) then these machines could be viable to operate right into early 2015 on a profit You really don't understand the risk. For every bitfury, there are 10x as many BFLs and Hashfasts. I know of one person on this board that paid 6800 BTC to hashfast and still doesn't have a single Gh/s to show for it. All it takes is one mistake to wipe you out. Whether it's a defective board that starts a fire, downtime you never anticipated, an exchange that goes belly up with your money there are hundreds of ways to lose as a miner. And only one mistake is needed to wipe you out. you compare the risk of a pre-order to the price of a product that is actually delivered (which IME creates a profit)For example, Activemining. Ken has taken 20000 BTC and turned it into less than 1 Th/s of operating gear. You invested in that right? I did - but i sold all my shares when btct was closing downAs I said before, it only takes one mistake to turn all your work into a loss. But that's if you go the preorder route. Everyone knows that preorders are uncertain delivery dates if at all. If you order in hand, or anything that ships within a week from a reputable seller like Bitmain, you have a great shot at ROI. I think 99% of Bitmain customers can attest to the low risk involved with buying from them. What's the warranty on Ants? I see anecdotes here that make me think failure rates are running over 20%. If your breakeven is 60 days and the hardware is a brick in 90, you aren't even covering your expenses. Absolutely not. failure rates are far lower than 1/10 if not less than 1/40.Then you have the labor involved in keep acceptable uptime. How many times do you want to drive to your hosting location at 3 am? Do you like the idea of never leaving town on vacation? Or how well do you sleep with the noise and heat and fire risk in your own home? ive set up my farm to run problem-free for days at a time, and with a remotre terminal for when i need to do something simple. Im working on making it weeks between visits, but i just like visiting it anyways  Ants have had a good run. It's probably over now. Mining hardware buys tend to run in cycles. Early on, it's a good move. Then it rapidly swings into losses. If you are naive about what is entailed in running a profitable operation you can easily be losing money without realizing it. antminer pricing is well paced to the bitcoin difficulty. still a good buy at current price, especially if you have couponsDon't get me wrong, I've been mining at scales >0.5 % of the network for years now. If you made the wrong decisions in 2013, bitcoin appreciation still made you huge profits. Expecting to get bailed out that way again is naive. |

I have two Antminer S1's ordered awhile back running and mining on Comcast. I just got two more at another location with Uverse. The Antminers can be accessed at their ip addresses, but will not mine. Default gateway 192.168.1.254
Any ideas, I tried many things to no avail. Hard wired ethernet and can browse from that connection from a laptop. Two working units have same configuration on Comcast, except for different ip's.
Any ideas?
Thanks
why is your gateway 192.168.1.254? About 70% of modems use 192.168.1.1 I guess because it is att Uverse... when I do an ipconfig it lists gateway as 192.168.1.254... I also set up a DMZ but still will not mine... My guess is Uverse is still blocking... Need some ideas? Thanks remove the ipv4 broadcast value - leave blank change DNS to 8.8.8.8 |

^watts at the wall was mentioned. this means that the measured power is about 10-15% more than what the PSU is putting out (probably around 85% efficiency)

The first ones are due to ship at the end of this week, or next monday. I imagine we will see more details very soon as bitmain does the final assembly,testing, and shipment for all the units
Well I am hoping they will actually ship before 1st April, like by few days before :-) I just hope they will send me a t-shirt or something cos number of Bitcoins I have sent them is equal to GDP of a small country... First Batch sold out in less than 24 hours... People started asking about Batch 2, after fews days that was sold out too... Now people are asking about Batch 3... People complain about pre-orders yet all of these companies are selling out in matter of hours or days... +1 I got in batch 2 but would not buy a batch 3 without seeing some proof of concept when batch 1 finally ships out. hopefully 2 pre-sale batches are sufficient to fund a larger batch 3 that can be sold from stock - Im also crossing my fingers for some hefty overclocking potential if these chips are all running at ~2/3 the speed of the chips in an S1 |

ebay users also pay 150-200% spot price for gold and silver

OR, you could just buy bitcoin today and make a 27% gain in 14 days if your prediction comes to pass. Why work hard all year, pay rent and electric bills, and risk capital on bitcoin gear to make less money?
You don't understand then. I buy mining equipment in BTC using coins I mined with the current hardware. When I am talking about a 20% profit i am talking BTC/BTC, not BTC/USD. If i hold my x BTC it will still be worth x BTC. If i buy a miner, I firmly believe I will make x+(30 to 40%) BTC minus electricity costs (at current price, about 25%). Most miners are negative. They are losing BTC. *smirk* yup - sure are $1750 bitfury (~17BTC) has made over 18BTC already and is still running at 260GH any antminer bought at >3BTC has already broken even all my other antminers will break even by mid august at the lastest my antminer S2 should pay off no later than october at that point, I will still have >4TH of paid-for equipment mining 'free' by the end of 2014.

I'd rather just buy one on ebay you would get it a lot faster and have paypal protection.
no one here is stopping you - but good luck paying less and actually getting it fast. Bitmain usually ships on a monday and it arrives wednesday (Canada) |

^in a month or two time is a different story. my point was just that switching today would be a bad decision with regards to profitability. Sometimes, I forgot that I don't have to argue with people who agree with my standpoint. +1. I thought you were crazy enough to underclock your farm today - doing it in a month from now would be much more reasonable (though you might have better luck selling the hardware to buy 28nm gear at that point in time) |

i'm sure its gonna happen if not bitcoin it will be another Bitcoin tech currency.
I have been thinking about this. Newer alt coins claim they are better than bitcoin, and rightly so in terms of asic-resistance and faster confirmation. It is also possible a globally central financial organisation like IMF decides to issue its cryptocurrency in future. Therefore, it is possible for bitcoin to be overtaken by its successor. The interesting part is how events will play out during the transition period. The extreme case is where bitcoin value immediately drops to 0, while its successor replaces it. This is certainly unacceptable to bitcoin holders. Another scenario is where both bitcoin and its successor co-exist for a specified period, while preparation begins for the successor to replace bitcoin completely. Any thoughts? asic-resistance is nonsense and any coin touting it will not succeed. the massive hashrate of the Bitcoin network on ASIC devices is key. If financial entities and professional mining firms are to arise it would be insane for them to be based on hodge-podge GPU mining. ASICs create a slick, powerful design and are already creating a market with good competition, and mining power is truly being dispersed worldwide. (The cost of saboutauge goes up and up, including the inability to covertly do it because of the huge power draws required making it easy to pinpoint the greater mining firms in a few years from now. It would be stupid at this point to build a 50-million-dollar, 5,000kW facility in order to attempt to overthrow the blockchain. A year ago that would have been a real possibility |

looking good! are those standard mounting holes - wondering if a thin thermal sheet with a water block would be a simple and powerful way to keep it cool

this is why BTC is going to fail; the mining is too centralized. It is the same problem as with the fiat currencies.
whats your solution - everyone be forced to mine with 1 GPU only or ou will be... arrested? its capitalism. I want to run as many machines as I can because it is making me money. I will not stop adding more hardware just because someone else doesnt |

Just a point.. the average investor would kill to get their entire investment back in 1 year.. just saying.
With bitcoin mining, you either break even in a few months, or you never will. With "average" investments, you may have to wait longer, but eventually you'll break even. ^that is not at all true. 6 months ago it looked like antminers and anything drawing >1w/GH would be useless by now. however, it now looks like they have another 4-8 months of profitable lifespan ahead of them. additionally untrue is your second statement. not all investment vehicles break even. equipment can burn out or break, the market can change, or the value of your product can dive. There is never a guarenteed break-even. but bitcoin miners stand a good chance You can construct any fantasy you wish and justify it by examining a time frame where bitcoin exchange rates increased by a factor of 15. The reality Syke is explaining to you is that in the current environment a miner earns as much BTC in the first 60 days of operation as it will in the remaining life of the machine. If you don't break even in that time frame, odds are you will never see a reasonable risk adjusted return on the investment. And bitcoin is as likely to return to $20 / bitcoin as it is to revisit $1200. clearly there are miners who think otherwise in order to be buying all the current equipment to the point of batches being sold out. I am not talking about bitcoin going to $3000 or $7000. Im talking about bitcoin rebounding to $700 which I think is a totally fair value to use in my calculations, and with difficulty starting to taper a bit (we were doing 30% jumps back in november) towards 15%/jump average over the last month, I see a window to make a 10-20% gain per machine by the late 2014 (breakeven around july/august, 120% by november) and with a $10,000 investment that is a pretty good outcome. bigger picture - im bullish. I think we are right near the bottom of the charts right now (might push to $525 at the lowest) and that a rebound to $650 will happen in the next 14 days, and sometime around may/june we could rally back past $1000. if this happens the bitcoins invested/mined will be worth even more than the power costs. ^yes, that last statement is speculation. But if it comes true, my 20% gains will be much closer to 30-40% gains. Not bad for a 6-10 month investment OR, you could just buy bitcoin today and make a 27% gain in 14 days if your prediction comes to pass. Why work hard all year, pay rent and electric bills, and risk capital on bitcoin gear to make less money? You don't understand then. I buy mining equipment in BTC using coins I mined with the current hardware. When I am talking about a 20% profit i am talking BTC/BTC, not BTC/USD. If i hold my x BTC it will still be worth x BTC. If i buy a miner, I firmly believe I will make x+(30 to 40%) BTC minus electricity costs (at current price, about 25%). |
