CBCM: $2.7/gh , ~1w/gh, $0.3/kwh hosting
CBCM: $2.7/gh , ~1w/gh, $0. 2/kwh hosting I did make a mistake there but $0.2/gh/month still translates to about $0.28/kwh at 1w/gh ($0.3w/kwh at 0.9w/gh) |

1680BTC, they must be paying out of their own pockets aswell to obtain 1PH
Not really. 2BTC for 1.2TH, shipping starts in 2 weeks: http://shop.rockminer.com/goods.php?id=35Thats 1.67 BTC per TH if you buy one unit. If you buy a PH and spread it out over 3 months, Im sure that price is negotiable. Of course you could buy some more peta shares instead. Currently a bargain, trading around 4.7 BTC / TH, excluding mandatory sky high hosting fees and with 50% of the mining revenue reserved to pay back a loan; and after thats paid back, 50% locked in to buy upgrades - probably at similar fantastic prices. Id hurry. I don't think PETAs hosting fees are that far off from this new mob. What are we talking $0.025 per gh? Don't forget PETA has slashed down their hosting fees after scryptx was deployed.. They are both bad deals as far as I'm concerned. However if I had to chose I would say PETA is a better offering simply because they have track record (along with HW online now). Here's a simple comparison: PETAMINE: $3/gh , ~1w/gh, $0.25/kwh hosting CBCM: $2.7/gh , ~1w/gh, $0.3/kwh hosting Rockminer: $1.1/gh, ~1.2w/gh, probably less than $0.3/kwh wherever you live. |

could you plz tell me which ethernet hub or switch to get, any advices be great. Shouldn't they all work? |

Very nice and exciting for the future to come! I'd love to work with a manufacturer and bring these to the US masses.
I'd love it if you'd do that ASAP.. First company to sell these for a decent price (~$1/gh) gets my money. |

Spondoolies chips can operate up to 119°C and are kept from overheating by dynamic, individual clock adjustments (on a per-chi basis).
I doubt that AM will implement that within a reasonable timeframe.
Both 40nm chips are made from the same fab so I assume they can operate at around the same temperature. If you like these units so much, buy them instead of spondoolies, once they become available.
Probably will if they are less than $1/gh. I think the preorder vs in stock debate has been done multiple times and both optios have valid arguments. I thought we finally reached a general consensus that preordering is not the way to go? |

They wouldn´t be nearly silent though, as you would need to push enough air through there to cool the ~700W per cube.
Looks like there is only room for 2 fans. And there is a huge selection on powerful and quiet 120mm+ fans. I think you are not quite undestanding these issues of thermal engineering right. If the unit uses 700W, that is the amount of energy that needs to be pushed out of the system. When one 120mm fan needs to push enough air through there, it is going to be loud, as you will probably need atleast a 90cfm fan. There are plenty of quiet 90cfm 120m fans. Not that you would need 90cfm. Spondoolies managed to cool ~1.3KW with 110 cfm iirc. |

Those have double the power efficiency and you will be left with some power gobbling, inefficient device. If they are extremely slow then maybe there will be a few sp30 from the first batch before these start shipping from stock. But I very much doubt it will take them longer than 3 months. |

And probably bad quality ...
You said it right - expensive door stop.
Just curious, which AM powered asic builder do you think makes bad quality hardware? I've seen nothing but praise for those overpriced r-boxes just like I've seen nothing but praise for those overpriced sp10s. |

seriously Jimmothy?
a miner that hashes at under 200GH/s cannot be compared with anything Spondoolies-Tech produces.
It is not even a catch-up on Bitmain. You are delusional. Sorry.
That rectangular thing hashes at 768gh (probably overclockable to ~960gh/s @ 10gh per chip). BTW you could put 2 of those cubes side by side and it would have more hashrate than an sp10. |

It is exponentially more difficult to deploy, needs more power than an sp10, doesn´t come with a PSU and takes up more space which transfers to higher hosting costs.
Management is also more difficult than with an easy web interface.
None of that is true besides having a better web interface if that matters to you. Power usage is about on par with sp10. It is not exponentially more difficult to deploy. Looks quite stackable. Any good hosting will charge you per electricity usage not space. Not that you would need to host it as there should be no problem with noise if it only requires one or two large fans. |

What bogus numbers? Do you doubt AM sold ~8ph worth of chips or that they have 60ph worth of wafers in hand?
I'm not doubting any numbers provided by Friedcat. I'm doubting that the hash-rate will actually come online. AM is playing and loosing catch-up game with Bitmain. Inferior ASIC, not relevant for Q3 https://bitcointalk.org/index.php?topic=641957.msg7227862#msg7227862It hashes at 768gh with 0.85-0.92W/G without PSU.  Admit it, that's a beautiful miner. |

... And by doing so you are putting investor level risks on customers ...
Completely untrue and false. September batch is covered. For every batch we open, we're covering it with the necessary financing. Does that mean no preorder funds were used to fund september or previous batches? Regardless of the funding, nonrefundable preorders are investor level risks. |

Not sure if I am being biased because I am an AM shareholder but that has to be the sexiest miner I've seen. |

We had AM_BE200_X24 boards produced and tested. We also sampled the compatible heatsinks and supporting structures for them. It hashes at 192GH with 0.85-0.92W/G without PSU. Power draws on higher/lower hashrate with higher/lower voltage is under testing. The design files of heatsinks/structures are going to be released a little later. It should be emphasized that QUAD and X32 are also produced and well tested before X24. My god it's beautiful. Where do we buy them?? Also how many chips @ 192gh? |

July batch was very small, builds on samples. August batch is medium.
So my basic understanding is that you are are short the ~$5,000,000(guessing around $0.1/gh) you need for 3 months worth of chips and are using preorders to fund it. And by doing so you are putting investor level risks on customers. We won't give actual numbers, just say that it's considerably less than AM advertised bogus numbers. What bogus numbers? Do you doubt AM sold ~8ph worth of chips or that they have 60ph worth of wafers in hand? |

Would 1 batch of preorders not be enough to fund the next 2 batches?
I'm a bit disappointed that you didn't understand the meaning of 3 months lead time. I'l explain in details: To finance September batch, I need to start paying from June To finance October batch, I need to start paying from July to finance November batch, I need to start paying from August So I need to pay 3 batches in advance, before I'm able to sell "in stock" hardware and starting to get revenues. btw: your precious AM system builders are taking pre-orders as well. Guy Did you not sell july batch before may? And august batch before june? Maybe you can't fund the entire august batch with only july preorder funds but I really doubt you need the money for a september batch. How much SP30 worth of chips could you buy with all the funds from preorders so far? |
