Isn't the 80/20 split done after the power is paid for? That way it is the profit you are splitting. It doesn't make sense otherwise.
Sure your way makes economic sense for the person mining but I think it would become an administrative nightmare for AM to figure out the energy costs for each miner. If AM uses all 60 PH worth of chips - that's 4000 x 15TH franchises. |

It didnt take Elenelen long to ramp right up to 500mhz with simple vrm heatsinks. Imagine what we could do if that cooling tower, thermal blanket, and that stupid bar were all gone, and replaced with an H2O cooler. the vrms, and any heatsink you put on them would then have excellent exposure to airflow.
If someone can mount an Corsair H80 on the chip and mount a push/pull fan configuration right on the side of the box you can literally bring the size of that box down to a small shoe box size. I've been using that Corsair H80 on my overclocked Intel 3930K processor for a while now and works great. It is a completely sealed system and keeps the processor cool at all times. If there is a will, there would be a way. The ASIC chips are larger in size, so making it work would take a good DIY'er. Do you know how much heat the H80 can remove? I think those ASICs are about three times the power draw of your 3930k... it probably wont be enough. depends on the speed of your fan, and ambient temps; but it can dissapate up to about 2500 watts according to a Corsair support specialist, but he couldn't give me solid figures theres the H-100 as well, but were only talking about a single asic here... about 400 watts max per asic(300 according to KNC) it can be done with H60's. How many watts of you think that cooling tower is capable of? It's already pushed it's spec limit. Surely even an H60 will be superior to that bulky archaic arctic tower heatsink. Whoa! 2500 watts would suffice  |

So for every 100s of my full shares I can get 15Th/s of mining gear for free from AM ? And I will get normal company dividends for that shares, plus 20% of what I mined "at home" as franchise? And that shares ale held as collateral in case I get robbed, I run away, or don't provide expected hashing power to the pool(cheating, self mining, not mining for AM but myself). Good. If this is the case, it's nice franchise program also for small miners and nice bonus for us, shareholders Interesting idea EDIT : AND it creates a demand for AM shares, because if you want to be franchise(in this program), you must own shares. So I can buy 100 shares for 20 bitcoins, put them up for collateral, get 20% of the mining paying my own electricity costs out of it and at the end of it all, I get my 100 shares back? Well guess what. At 15 cents US per kW.h and Bitcoin at $650 USD your power costs ARE 20% of what you could generate today! You get nothing but loss from this venture. 15 TH/s generates 0.4485 BTC per 24 hours 1 kW.h @ 0.15 cents US = 0.000230769231 BTC /kW.h 15 TH/s of AM GEN3 uses ~ 16.5 kW 16.5 kW.h x 24h x 0.000230769231 BTC/kW.h = 0.091384615476 BTC 20% of your production (0.4485 BTC per 24 hours) = 0.0897 BTC As you can see, it sucks. Also, when diff goes up, it sucks worse. Check my math but I think I'm right. |

There was actually "Talk" early on about a dc/dc "Team" who was supposedly working on a custom solution if I remember correctly.... evidently that never transpired.
Nobody volunteered a Neptune box as a guinea pig and the crowd funding never got off the ground. I might play around with one of my 4 VRM Saturn modules and see if I can upgrade the VRMs on it. The problem is, they are GE Critical Power modules so any results wont be conclusive for Neptune owners. |

I have asked Friedcat about the franchising mining farm,Friedcat replied me by E-mail that the franchising mining farm will be work after the mid of July. BTW, I will be a small franchise partner too  each 100 Asciminer shares will mortgage 15T hashrate . franchising will get 20% mining profit when deduct the electric fee . Anyone wish to elaborate this means? If you have 100 AM shares, you can put them up as collateral for ~15T in mining gear, where you personally keep roughly ~20% of Profits/(Take Electricity Cost) (Meaning the other ~80% goes to AM for Divs/BitFountain)? If this is the case, that is really cool. This sounds really really cool. yes, that's the case. I was confirmed with Friedcat. NOT cool at all. That would be ludicrous. At the current value of Bitcoins in USD that means you are putting up $1.25 per GHs and getting back 20% of what that will mine after electricity costs? Did we not already BUY those chips with the profits from our company? There is no way we have to put up our shares to get the hashing!! If AM is giving away the chips for a deal like this, then we should be getting a percentage of those proceeds from mining based solely on our ownership of those shares. I fail to understand how you think it's "cool" to have to use your shares as collateral for such an operation. It would be much better for your to sell your shares, buy mining equipment that uses more efficient chips and keep 100% of the profit after electricity costs. I sincerely hope that this is not the deal FC cooked up. I cannot believe this for one second. |

6 months ago I would have said wowza to 3.5PH/s. Now it barely makes 0.1 BTC/day. My condolences  But I guess they did manage to stick to the Q1/Q2 promise....sort of. Yeah sort of... They originally said they would start delivering in March. It seems nobody remembers this fact. https://www.kncminer.com/news/news-24It seems that KNC is very good at saying what people want to hear but not necessarily doing what they say. |

I have removed the Neptune aluminum plate. Now I can see the Ericsson VRM's..... this is bad: they are the BMR4641002 (max 40A) instead of the BMR4641008 (max 50A).  ...... no OC possible ! The 1002 has a OverCurrentProtection of 48A and looking to my Advanced-page: nearly all the VRMs are already around 46-47A (and this is KnC's default setting). They should have used the 1008 instead, which has 50A and an OCP of 62A. Can't we just desolder the 1002 and remove them to be replaced by soldering some 1008s in their place? Doesn't that mod seem like a good solution? What do you think? if you can surface mount then go for it...but that would add alotta cost onto the unit...and also why stop at the 50a model...why not go higher if yer gona do it? hehe more room for oc'in  You have no choice but to stop at the 50A module - that's the end of the BMR464 line. well that sucks and it would have to depend on the 50a model having the same layout as the 40a model wouldn't it? i don't see why they would be different but ya never know AFAIK the modules work exactly the same way but the 50a model has three extra settings on the PM Bus to control dynamic loop compensation which is not available on the lower rated modules. |

You're going to spend another 1200 dollars to get what? I think you'd be better off buying two Bitcoins and mining with the OEM boards using inexpensive cooling modifications. OR we crowd-fund an experiment and get one lucky miner to test your theory on just one of their 5 boxes. Everyone not interested take a step back! |

Hi I'm wondering how much cooling I need for my asics. I got a little trailer 150 width x 240 length x 170 height. My plan is to but my asics into this to be able to transport it easily. I will cut a hole trough the wall for each asic so they will draw air from outside the trailer, therefore I expect it would get quite hot with 10-15 miners at 1kw each... But if I put a big exhaust at the top of the trailer wouldn't I spare quite a bit on cooling considering I'm only using power to get the hot air out and not cool it down/or suck it in... Anyways if I'm doing my calculations with 10 miners it would be: 10000 * 3.412 =34120 BTU. So do you guys think I really need that much cooling (34120 BTU) for this or would it suffice with less considering the miners will always draw from cool air outside the trailer ? Any ideas are welcome Sorry for my english I'm living in norway so the outside temp is 20 +/- and -20-30 celsius at the winter. Calculations are as follows: Q(cfm)=(3.16 x P)/dT(f) or Q(cfm)=(1.76 x P)/dT(c) where Q(cfm) is the required flow in cubic feet per minute required to dissipate power P (expressed in watts) using the difference in temperature dT in either Fahrenheit (f) or Celsius (c) for example if you wish a maximum 20 Celsius degree rise for 10kW worth of mining equipment: Q=(1.76 x 10,000)/20 Q= 880 CFM of course in the winter you will have a larger dT of up to 70 which means Q=(1.76 x 10,000)/70 Q= 250 CFM The size of your enclosure is not a consideration for this application. If you were trying to ventilate a bathroom, then you would need the dimensions in order to select an appropriate fan/blower. These might work http://www.aeroflotech.com/ecatalog.php?fantype=residential&fid=65&s=In-Line+Duct+Fans# along the side walls of the trailer as near the top as possible. |

Avenger, good to see you are still trolling this thread. I know you guaranteed many times that nobody would get a neptune before the end of Q2, but here we are again and KNC is shipping.
Get a life, move on from this thread.
Avenger's posts are thoughtful, informative, well-constructed and occasionally quite humorous. His graphics are second-to-none. I have used this forum extensively for KNC hardware issues, over-clocking advice and purchasing/refunding advice, I even learned about the 4 vs 8 VRM screwing I got for being one of the first to purchase from KNCminer and I have found Avenger's posts to be very useful. We need to hear all sides of the discussion; even yours RickJames. Aww, how sweet.... and how "thoughtful, informative, well-constructed" were his comments when he told everyone that KNC filed for bankruptcy?
https://bitcointalk.org/index.php?topic=552854.msg6016471#msg6016471  Hey, I like your posts too Phoenix but you don't put quite as much into them as Avenger. |

hopefully we will hear how one of our fellow bitcoiners were solomining with 1 rockminer @ 33ghs and solved a block.....
while it is possible (probability is greater than zero), statistically it has terrible odds of happening. 32 gh is .001195 btc a day. divide that into 25 = 20,920 to 1 for a 1 day run at the current diff level. run at the current level for the next 6 days odds are 20,920 / 6 or 3486 to one. any miner that plays the 3 or 4 digit numbers at the local lottery
rather then running 1 of these units at solo-mining is pretty foolish.my frustration is no major pool offers this option with the exception of oz-coin's solopool.net .. Since that pool's op had a major money issue I do not want to use him and running solo in house cost too much as I need to dedicated a pc to run as a server. I really want to offer these as 3 packs on ebay with an easy setup to run two in a standard pool and one as a solo miner. Sadly no pool that I would trust wants to do this. So a good promo is lost. Actually, to do you calculation correctly, you'd have to actually compare it to the total bitcoin mined in a day, since you're using your daily output, not a block. If we were averaging the spec of 1 block every 10 minutes, that's 3600 btc per day. You're likelihood to mine 1 block would then be 3600 / 0.001195 or 1 in 3,012,552 to mine a block over the course of a day. Estimated time to mine 1 block is actually 20,913 days at 32 gh/s as calculated here: http://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=32&p=0.00&pc=0.10&pf=0.00&d=13462580114.52530000&r=25.00000000&er=570.00000000&hc=0.00So your odds are worse than hitting a pick 5 lottery and better than a pick 6 (at least in NJ). So you'd probably be better off pointing it at a pool than wasting the hashes trying to hit the lottery. your math is wrong. think about if you math was correct merged pool mining would not work at a profit and it does. 672 th mines 1 block a day at the current diff 672th/21000 = 32 gh so if a pool had 21,000 32gh r-boxes it would make 1 block a day (perfect variance assumed) this means 1 r-box is a 21000 to 1 shot at pulling a block …… it cost 15 cents to run it a day and you lose 68 cents in pool hash earnings. total of 83 cents…… so 83 cents gets you a shot at 25 btc = 14560 usd . the odds to hit are 21,000 to one. no state 3 digit or 4 digit number pays that well 14560 usd for 83 cents when the real odds are 21000 to repeat I am not saying it is easy to hit. I am saying it pays off closer to true odds. then any state 3 digit or 4 digit number. if you play 3 digit and 4 digit numbers and you are not playing an r-box at solo mining you are mathematically making the wrong choice by far at todays diff and todays btc price. a fact that you think is not true . BTW it is cool if you keep thinking that way. you are entitled too believe what you want. I know I believe more then one thing that is not correct at all times, but not this at todays (June 26th 2014 )numbers. Your numbers look close but the odds to hit are NOT 21000 to 1 - if they were, everyone with a rockminer would be rich beyond your wildest dreams. I think you guys are confused about odds and probability in general. The probability of a single hash solving a block is blockexplorer.com/q/probability The odds in favour of solving a block is expressed as the probability of solving a block over the probability of NOT solving a block. Which will come out to approximately the same as the probability because the denominator is so very large. Now you can multiply the probability by your hashing rate (32billion for the rockminer) and then by 86400 (the number of seconds in a day) and you will get the probability of solving a block with a rockminer on any given day. If you want the odds in favour of solving a block on any given day with your rockminer, take that probability and divide it by 1 minus that same probability. Also, you can invert the probability blockexplorer.com/q/probability to get the average number of hashes required to solve a block. Now you can divide that number by the hash rate of your device to get the average number of seconds required to solve a block. I think it's around 57 years for a rockminer... |

Just ask for refund for my titan order and they say all sales are final... KNC become so lame company and tread customers as slaves ...
Why would you ask for a refund? KnC said from Day 1 there would be no refunds on Titans. Where does it say that for customers converting orders? " For those of you wanting to convert an existing Neptune order to a titan order please contact customer service for assistance." I wonder how customer service can switch out the orders without issue yet not be able to effect refunds in a timely manner. Just don't get it mixed up....they likely would let you swap a Titan back to a Neptune at this point heh Searing Wonder if we would be able to swap out our bitcoin refunds (which they said would be faster than USD refund) back to a USD refund since at this point they both seem pretty darn slow. |

I guess the big question I have for those who have received their Neptune's in the US and in Canada (if there aren't Canadian's other than myself in this thread) did you have to pay duty if so how how much?
Thanks,
You don't have to pay duty but you have to pay the HST @ 13% of the declared value after converting to CAD which is a real downer since our dollar plummeted against the USD since last NOV. I've had to pay this one every miner I've purchased... yes I got BFL'd. depends what province. Alberta should pay 5% GST only. *edit* plus probably some kind of brokerage fee Yikes, so I guess I would like to know if any of the B1 customers are from Canada here and when they get their Neptune what does KNC mark its value as, because that's how they determine the HST. For us Canadians that could mean paying an extra $1500. I cancelled my order so I wont know about the Neptune but when I got my Saturn they marked the full price on it. I was expecting the same for the Neptune. I would think anyone who has received their Neptune order could tell you what price was declared on the shipping label. Does anyone have that info? |

@ Phoenix Most residential AC has 2 phases/legs installed. All you need to 'make' 220 is a doublewide breaker. (the phases are staggered and every other breaker is on same leg) Exception is 3 phase industrial panels where it is every third breaker. In fact most double wide breakers are 2 single breakers screwed together with the switch levers connected. If you have a voltmeter and long extension cord you can prove it to yourself. Just plug in the cord and measure from cord hot to outlet hot. (hot is small prong/hole in US outlets) Same phase, hot 2 hot = 0 volts. Different phase, hot 2 hot = >220 volts. The main REASON a miner would insist on 220 is efficiency. A >220 PSU is often 10% more efficient at making 12VDC (depends on model) I'd guess you have 220 and don't know it. I don't claim to know what service is installed in Volcano, HI. though. YMMV And also 220v is slightly very slightly more effective at carrying the power through the wiring as there is less resistence with higher voltage. The main reason the US has 120 ac is because the voltage cant kill someone as 220 can if they get shocked. Line losses due to joule heating are proportional to I 2R so if you double the current (which you would with 110V as opposed to using 220V) you quadruple your line losses. So let's say you have a run of seventy feet of 14 awg copper wire and you run an 1800 watt miner on a 120V circuit. Your losses would be about 2.5% or about 45 watts. Run the same miner on the same circuit @ 240V and your losses are about 0.6% or 11 watts. |
