Roughly $65k for 50 MH/s.. I need to setup a scrypt mining company  After our initial raise, we are hoping to add up to 50 mhash to our network and further expand from there.
Woah, woah. That sounds pretty ambitious. Can't tell if you aren't familiar with scrypt mining, didn't pick up the fact that he was stating scrypt mining speeds, or you are trolling. I'll assume one of the former. |

but you know whats crazy is guys paid 50 BTC for blades and have been mining since mid May reaping a fortune and if they were smart they sold it a couple weeks ago. They were still selling for 35-40 BTC WAY over ROI. People told them they would never ROI at 50 BTC but if they sold for 35-40BTC a few weeks ago they probably made a fortune.
I am not sure I understand what you are trying to say? They bought a blade in Mid-May, then they haven't gotten anywhere near their ROI up to now. Thats is less than 30 days span of time to make any BTC before they "allegedly" sold it off. If they then sold them off for 35 or 40 BTC then that means for them to break even...they would have had to have made anywhere from 10 BTC to 15 BTC in that lapse of time. This only to actually break even. So your statement is confusing. Are you saying that someone who purchased a Mid-May blade made back at least 10 to 15 BTC before they sold it off to some other fool for the remaining difference?? If not, then they just got out of it what they put into it...at best. i got a blade in May, made about 21 BTC with it till last week, and sold it for 35 BTC, not a very good deal, i admit. It wasn't too bad of a deal. With NMC conversion I made around 26 BTC and with the low $66 USD price of BTC last week I sold my blade for around 60 BTC on eBay. Assuming I don't get a dispute months later, it is hard to argue with a ~36 BTC profit in 2.5 months. |

Hey thanks for responding, I can appreciate your concern.
Now try to imagine this from my perspective, you registered less than two months ago, have a zero trust rating, and this is a good chunk of BTC. BTC that belongs to my shareholders BTW, not me. As a result I'm more cautious than I would be with funds that were 100% mine. Also I've already done this once with another seller and it went off without a hitch.
Perhaps a comprimise? A meeting in a public place and a simple open cover examination of the rigs?
Cheers.
Escrow. |

Someone should just try throwing their Jalapeno in a deep-freezer and mining @ -20C. I am serious, I want to see results  If I had one I would. I did all sorts of refrigeration cooling things when I was overclocking CPUs and GPUs with the culmination of a failed 3 stage cascade. If the jalapeno had software voltage control it could really open up some interesting testing. I'd prefer though a single chip PCB like the test PCBs that were used for Bitfury testing. Could be fun seeing how the chips perform down at -100 Celsius |

I heard power consumption will be decreased. The original blades are 8.3 Watts per Giga Hash, so lets hope that gets cut in half.
That would put a 10GHash blade at 41 watts and a half blade at 20.5 watts. A 20watt 5ghash miner with built in controller is absolutely perfect for my purposes.
I hope the price comes down quite a lot too. But I'm not holding my breath
Power consumption is not going to drop like that. They are using the same chips and unless they can decrease the voltage to dramatically increase efficiency and then use more chips, they won't see a magical efficiency gain. They might gain a few % optimizing the power conversion. |

he should have set the price at the 24 hr high, I hate it when he holds the price down like this.
Buy into his wall then and liquidate when the wall is eaten. |

I have 2 AX1200s that I ran at 1150-1250w from the wall for 9 months with ambient temps around 25-35 Celsius. Zero problems. I'm reassembling those rigs right now after replacing failing/aging components and plan on pulling the same wattage for another ~9 months with zero concerns about the PSUs. My HD 5970s died long before the PSU quit on them.

Asicminer announces 800 to 1000T for second half of year finally reaching 1P of hash rate. They also announced the development of a lower nm (maybe 55 or 65) which maybe announced over the next week.
The speakers started with Tencent representative laying the basics for bitcoin. Btc123 forum followed up with in depth explanation on blockchain. Asicminer then took the stage on their share price history. Whole event took about five or six hours.
More news coming in...
Ermm..... so they're going to take the entire network? Even with everyone shipped, that's on a scale like we've never seen and will kill all mining. It is ASICMINER.. they will likely in total produce 1 PH/s of hardware and sell sufficient quantities so as to not risk the chances of a 51% attack. |

Hey Alten,
How is the box for heat? Any issues? Uptime etc?
No Issues. It's been really good to me. It is a solid product. Wish I had my kilowatt meter, but the exhaust air is not much warmer than the air going in. i think that is a good sign. Finally put it back up for sale like I said I would other than its a week later: https://www.bitmit.net/en/item/41878-54-gh-s-bitforce-single-shipping-nowAre you going to take whatever offer shows up on bitmit or are you still doing the 25k minimum, otherwise mine thing? |

Any news from DeadTerra with bitfunder dividends?
I want to know the same thing. wtf is going on? +1 Lucky me, DeadTerra is the only major player I do not hold shares through  In the terms of the asset does it not say they have 7 days to pay the div? He's away for another day or two, he mentioned it in one of his threads a few days ago. Bad communication from the pass-through operator. When you hold thousands of bitcoins worth of assets, a simple "I'll be back on the 29th of June" in each pass-through would have been awesome. |

If we's gonna cheat  Space shuttle was technically liquid cooled. If I recall correctly the nozzles were cooled with cryogenic hydrogen that was expanded in tubes surrounding the combustion chambers and nozzles. This expanded hydrogen was then used to drive the oxygen and hydrogen turbopumps that fed the main engine. The wikipedia article has some neat details of how the system worked -> http://en.wikipedia.org/wiki/Space_Shuttle_Main_Engine. For reference, each hydrogen turbo pump was around 70,000 horsepower per engine. |

Those that have the AVRDragon should loan them out with a deposit. Save everyone some money and they could make a little money in the process. Congrats on getting this to work, look forward to people with little singles and singles tweaking their boards.

Give us an estimated price I dunno what to offer.. Something in the 25-35 BTC range would probably be acceptable. You can always offer and he can always turn you down |

Im in northwest ohio I feel 3.5 to be a reasonable price including shipping within the us
New ASICMINER USB Block Erupters are 333 MH/s for 0.99 BTC. I'd say that's the MOST someone should pay for mining gear. Given the increased power consumption and noise, I'd say 2.25 BTC is a fair price. yeah... like you can get a hold of that thing within this week... I am selling 6 of my FPGA as well.. and I am not going to let them go anything lower than my asking price... @OP.. you too don't fall for these people trying to lower the price down... that USB thing dropping its value... must mean something... BFL FPGA never dropped its value... I just messed the trade-in date... but the last trade-in value is still $599 and almost 6 BTC... just my 2cents Not quite understanding what you are saying. Are you suggesting that you won't get an ASICMINER USB Block Erupter within a week? My understanding is that there are a number of USB resellers(even btcguild is reselling these..) and the restock time is under 1 week from ASICMINER. They are dropping in value as Friedcat lowers the price to match their expected earnings and to revitalize sales. They are in my opinion still incredibly overpriced but clearly the market is willing to pay. BFL FPGA's were worth $600 when the trade-in program was running. I bought a BFL FPGAs at just under $600 just for this reason. Unfortunately, BFL chose to end that program and now the BFL FPGAs only value is in their hashing performance and efficiency. |

11 BTC. I figure if I tweak the firmware it might earn that in 3 months, it might not. Anything past 3 months is too hard to tell with so much unknown hashing power possibly coming online.

Wow, that really changes the bang for the buck equation.
What does that do to the temps and power draw?
Judging by his previous posts, he has an A/C unit that draws as much power as the Avalon itself blow cold air into the intake: A fine solution if the additional 20 GH/s is earning you more than the increased power consumption. Curious though how sustainable this is unless it is a 4 blade unit? |

Nickle/copper is fine. Nickle just doesn't tarnish like copper does so your blocks won't turn brown. I have been running a mixed nickle/copper loop with a silver kill coil since ~2011 with no problems. I'm just running distilled water and shitty home depot 1/2" tubing. Get quality barbs and utilize zipties or hose clamps and you won't ever have problems with hoses stretching and leaking. I have been using Bitspower's 1/2" barbs with great success. |

Hi,
To my understanding ASIC's are application specific and thus requires me to have an ASIC designed for my specific goals. As my code'] implicates highly non-standard calculations (no double sha) a far cheaper goal would be to go with GPU's. My goal is to build a 32 GPU cluster. Each node with 4x 7990 = 8 GPU's so with 4 machine's I'm all set.
Now only the cooling is an issue which I think would be solved by using water cooling (chillers) instead of open-air systems and heavy A/C units.
You wouldn't need a water chiller, much simpler design for 4x7990 would be a triple liang dcc and dual/triple 480mm radiator setup. Then you don't have to worry about chiller control etc. 1 x Thread Laing DDC Triple Acrylic Pump Top : Plexi 3 x Laing DDC-1T Pro Pump 440 L/hr 10W2-4 x Swiftech MCR420XP Extreme Performance 480mm Quad Radiator8-16 x Zalman ZM-F3 120 x 120 x 25mm 1800RPM Case Fanplus the waterblocks for your graphics cards, some tubing and some high quality hose clamps. T line is much easier than using a reservoir and means there is less to spill if something goes wrong, I'd still recommend distilled water and some kind of anti-conductive additive though. Although expensive it should keep the cards at a delta between 10-20 degrees max compared to ambient air at full load depending on how many radiators you decide to use. Get a silver kill coil and distilled water to handle any biocide requirements. What is an anti-conductive additive? Short of using something like fluorinert I don't think there is a way to prevent the water from ionizing given the constant contact with copper. |

Look into some of the open-air frames that have been built. I know gigavps sells his frame in the marketplace here. By giving the cards a few inches air-gap you can run 100% load on the stock cooler. Waterblocks are fantastic for compute dense configurations but there are all sorts of maintenance issues around those. For example I just discovered that a large quantity of my HD 5970 waterblocks have warped acrylic covers. Pain in the ass that could have resulted in a dead motherboard and possibly dead video cards.
For simplicity and if you have a location where noise isn't a concern, go with open-air rigs. If it must be cased then look into waterblocks.
