Pool choice can not affect hardware error rate. It is impossible by definition.
A hardware error is when the *hardware* has an issue. There could potentially be an issue in the mining software that can misreport hardware errors, but that also has nothing to do with the pool.
I think we understand that a hardware error shouldn't be attributable to the pool. What I would be interested to find out is what difficulty level is being set by VARDIFF on the machines? My Oct Jupiter (552Gh/s) has a 512 diff, whereas the Nov Jup (654Gh/s) has a 1024 diff. That could have an affect? I remember cgminer developers talking about the difficulty calculation being relative to the diff, but I could be wrong. Wiz could you try setting the VARDIFF for >750Gh/s back to 512 see if that helps? Or those who have moved pools can you check your KnC machines? It shows in the cgminer status: Connected to stratum.mining.eligius.st diff 1.02K with stratum as user blablahblah |

Any word on reopening 28nm sales again? These excess bitcoin are burning a hole in my pocket. Especially with BTC prices back up. I'm done with preorders for now (I think), I just want more hashing power NOW!
Would go against the KnC network protection policy I think, yes if the competition was launching significant compute power into the channel then i think we would see more Jupiters for sale, however: CoinTerra announces one or two week delayI spoke with "Peter" on the phone last Friday (December 6th) and he said that the first deliveries will be pushed back 7-10 days...so I doubt anyone will receive anything this year. BitMine.ch announces three week delayhttp://bitmine.ch/?p=4192CoinCraft Delays in December batch units Posted on December 10, 2013 by Giorgio Massarotto in Coincraft series, News Due to a shift in the production of our CoinCraft A1 chip, a three weeks delay affecting December-batch units has just been announced. Nobody likes to hear about late deliveries, especially in the Bitcoin mining world. While we tried to do everything we could to carefully plan the delivery terms, sometimes delays still happen in places where you have no control of them. This is the case of what happened yesterday, when we had a conference call with the supplier of the chip to follow up with the delivery schedule of the CoinCraft A1 ASIC chips, which were supposed to arrive at Bitmine’s assembly plant this week. Unfortunately, the production of the silicon wafers used by our chips has been delayed by three weeks from the factory, effectively forcing us to delay the December batch orders. BlackArrow still hasn't taped-out?Does anyone know if these guys have actually taped out? I find it extremely hard to believe that they will deliver anything in February if they have not taped out yet...
Not yet. They do need to tape out asap if they want to hit a Feb date. So it appears only Hashfast may launch anything before the end of the year now. |

never seen a 5 days shipping from usa to france , man ...
If you ship a package with DHL or UPS from the USA on Friday it's guaranteed to arrive on Monday in Brussels. France should not be any different. That is 4 days max (Friday evening pickup, Monday noon delivery) The closer it gets to Christmas the more you can throw any express delivery dates out the window unfortunately. |

|
|
OK we are today 11/12/2013 , i'm in france :so..... it's impossible to have a delivery for 31/12/2013., since hashfast at still dont tell anything at this time..... No, this is wrong. We will have to wait at least the 25 for this conclusion. |

Is there anything I can do to get these cores to work? On board 3 none of the cores work, and on board 2 about 24 out of the 192 cores seem to stay off. I just got the miner today and when I initially started it up the hashrate climbed up to about 660/670, but later i checked and noticed it was running at about 480GH/s. https://i.imgur.com/OipHElT.pngI also have the same issue. 2 Nov Jupiters, both have their own 1200w PSU. Both started off at 660+ GH but after 12 hours one unit is at 500GH with all cores disabled on one ASIC board Tried hard reset, checked connections Has anybody managed to salvage such a board ? Thanks try change pool eligius have problems witch kncminer I don't believe this to be true. Mine are working fine on Eligius.  I'll check it out I still have accounts on BTCG and Slush as well and BitMinter. |

What happened to the "Reservation Queue"? Did anyone get notified that their reservation queue order was due for payment or did they just simply cancel it?
Cancelled apparently http://bitmine.ch/?p=1920 |

Regarding the VAT thing, lets just say that we have it covered. Customers in the EU will not have to pay VAT or Import taxes. How ever we get it done, with a vat registered company and a non vat registered company we are currently receiving payments from EU clients and we are not charging vat to customers, and those clients will not have to deal with vat when they receive their miner.
If you think that then you are very wrong, any EU company that is VAT registered has to charge VAT on the invoice, as for import taxes we wouldn't have had to do that anyway. The only way you would not charge VAT if shipping from inside the EU would be if the company you were shipping from was not VAT registered, which it would have to be if it was going to do more than 30-40K EU of sales per annum. |

Thanks for the advice.
I gave it a go to no success, then powered it on with no boards attached and it detected the IP.. Weird!
When i then add the boards gradually it then freaks out and turns off.
Try one board, if it works with one then test the other ports on the KNC controller board with that one. If it doesn't work, try another board till you find one that works, if none work then get an RMA. |

BlackArrow has been claiming that somehow running a Bitfury mine is proof that they can deliver their own design.
They never made such a claim. Instead someone visited their factory and took pictures of a bunch of bitfury boards there were running. That's all. I am, however, still waiting for an explanation of what all those boards are doing there. They were said to be customers' boards. If that's so, why haven't they been shipped out to those customers? I'd like an explanation as well, it does seem mighty strange that they had.. well from the pictures I saw I wouldn't call it "a bunch" I'd say the collective term for the number of bitfury boards I saw would be a "megashitload", or often translated to a "mine" of boards  Holy crap. People bought the chips, had them assembled and hosted with BA. Just happens to be the only place with enough power is their factory- there office allready has too many miners and was blowing breakers. Why is that so hard to believe? Its not hard to believe at all Mr Bob, its just the first I've heard it explained that way. |

if you are a non-vat registered individual in the Eurozone then a VAT registered company selling to you from anywhere in the EuroZone has to charge VAT at the rate tied to the country where the company is resident, in this case Bulgaria which is 20% That is correct and complete. If I buy in one of the member states of the european union, the company needs to receive the VAT. The goods are then free to circulate in the eurozone. If the VAT registered vendor ships to another VAT registered entity in the EuroZone then the invoice will not have VAT but the recieving company will have to pay the VAT at the rate in their own country. That is true. The buying company needs to give their taxnumber and country initials to the vendor, then the vendor needs to check the number, if it checks out then the sale can be done without VAT. The buyer is responsble in his own country to declare the goods. And given that most individuals here are not VAT registered companies they are consumer level customers, who will be charged VAT on the invoice, it sort of doesn't make sense other than as AMT_Miners said, from a US sales tax perspective. |

We have to pay the VAT anyway. When the goods come from ouside the eurozone and arrive at the customs, they check the value of the goods + transport. If the think the value can be correct, then we pay 21% over the goods + transport when it arrives at home. If they have doubts.... then it's going to take a long time.
Bulgaria has very low taxes for companies to pay. Corporate tax is 10% and is regulated by the Corporate Income Tax Act (ZKPO).
Clients however pay 21% (here in Spain) when the goods arrive.
So, if the goods are send from inside the European Union (euro-zone) only then we don't need to pay VAT. Where ever we pay the bill, has nothing to do with that.
What AMT is saying to you, not to me, is that they are sending from within the euro-zone?
No, if you are a non-vat registered individual in the Eurozone then a VAT registered company selling to you from anywhere in the EuroZone has to charge VAT at the rate tied to the country where the company is resident, in this case Bulgaria which is 20% If the VAT registered vendor ships to another VAT registered entity in the EuroZone then the invoice will not have VAT but the recieving company will have to pay the VAT at the rate in their own country. |

AMT responded to the Bulgarian bank matter...
We use a Bulgarian bank for our European clients as we have several. Otherwise they will incur a VAT (value added tax) charge which is an additional 20% on top of the purchase price. So their 1.2 would cost them $5,999 + $1180 + import taxes on the total value. By operating within the European Union, we are able to save them VAT costs and import taxes as well.
Can anyone refute this?
Doesn't make sense, you have to pay VAT regardless if you are in the EU. If you buy something within the EU you have to pay VAT included in the price, if you by something from outside the EU you have to pay VAT when it enters the country. There is no getting out of paying VAT. If you are a VAT registered company then you can get an invoice that does not have VAT on it, but you still have to pay VAT when it enters the country. Plus there are no import duties for computer components or equipment entering the EU from the US |

Almost all vendors in mining industry can be called scam.
Why companies don't use any buyer protection payment method?
It's too easy.
Use Escrow (or some like that) to get funded, then borrow form bank for production and refund after shipping.
Even credit cards were accepted only by P****nix.
Answer is simple, they shift all risks to buyers. But 2 months delay with shipping is the same as no shipping.
Is that not scam?
So what are you trying to say? That we should trust you because you are acting as a middle-man on behalf of "scammers"? Even though I don't actually think that all of the hardware vendors are trying to scam anyone, I think that there are a few who are a worry. Its certainly a risk putting your money down on a pre-order without some sort of safety net such as Credit Card or PayPal. However, I'm sorry, but I don't see how you're idea is a solution to the problem, it just makes it worse. |

when people learn that they are better buying Bitcoins that investing in a pre-order than everything will be just fine.
buy only from stock, I don't care about how they will make an Asic let them get a mortgage to finance their own process, because they will have allot risked this will be the only way they will take their clients seriously. and they will race to finish their design ASAP. you see win win case.
It has been proven many times that Holding bitcoins is way better than investing in pre-orders, but people still risk their money just because of "what is it is different this time" .
The problem is that if you wait till there is stock then your unlikely to get any because they will all be sold. :| |

standard disclaimer //
Immersion cool in baby oil (paraffin oil) (About $5 per liter not buying it in bulk), circulate with a quality car windscreen wiper fluid pump or electronic fuel pump. The reason for this oil choice is its availability and its not very viscous at all. These are about the same cost as a "gaming" water cooling pump but far more better quality and more robust: just get one from your local car junkyard they should have millions. Also, fuel pumps are designed to handle non-polar fluids (which includes oils) so they're more likely to be compatible with the oil than a random watercooling system pump which may contain materials that will disintegrate / dissolve / embrittle in the oil.
Get yourself a portable air conditioner, or external unit of a split system air conditioner and have the gas removed by a licensed refrigeration mechanic (of course). OR, a second hand car radiator. All of these should be able to handle over 3 kW of heat assuming you put some decent fans near it. Even with silent fans you can remove immense quantities of heat thanks to their ridiculous surface area.
Tubing should be silicone (medical) tubing or fuel line tubing that automotive and some hardware stores stock. Fuel line tubing costs about $7/meter where I live for 2 mm thick walled stuff (Masters Home Improvement centers, Australia). Medical tubing is usually even more expensive ($10+ /m) and not necessarily any better and you'll probably find stock in your country is monopolized by companies who specialize it selling it.
Before installing the system for real, you should place it over some kind of sealed basin or container and leak test the entire system with its full lengths of tubing for at least 1 day. However as some materials are semi-permeable to oils you should think about testing it for at least a week if you want to be cautious.
If you have access to a quality router with metal routing bits you can easily make your own waterblocks with a moderate ammount of fore planning their design. It should be made from aluminium. If your have a router or CNC capable of doing this work then you don't need to be told where to get metal from. You can buy silicone sealant strips or rings, and silicone sealant type glues from any half decent hardware store to make the seal.
If you dont want to make your own 'oil blocks' then you can buy the relatively large (and relatively dodgy) Chinese eBay waterblocks. I have heard reports that they CAN be used with oil.
It's also worth keeping in mind that although its VERY hard to ignite paraffin oil without preheating it to at least a few hundred deg C, it can burn. And if it starts to burn and you have a few liters of it you have a extreme problem. I recommend that any high-current cables passing through the air-water interface are sealed inside of a metal tube so that if there is a fire in those cables then it cannot contact the oil interface. It is almost impossible to get a resistively heated wire to ignite oil if it is fully submerged in the oil. It can only ignite if it manages to heat the entire oil mass to its autoignition temperature or if it can come into contact with the air-water interface. I recommend you test this for yourself with a small qty of oil and and old ATX PSU.
You start off talking about immersion then you talk about machining 'oil blocks' I understand the concept of both cooling systems, oil immersion and using blocks with fluid, but why would you bother running oil through blocks when water is a) cheaper, b) more efficient at removing heat from the block? |

knc 1200 machines at 600gh = 720th . about a full 10-12 percent of the 27% jump to come in a day or 2.
also bitmain shipped 180 180gh machines that is 32th.
None of us know how much either of the above companies are mining with gear built and not shipped. BTW with closet to 7ph mining as I type any company may be mining rather then selling.
Our much loved BFL may have 1000 Monarchs Mining as I type. They are building a cloud so that you can let them do all the work. For all we know it is up and running why not mine at 707 mill diff and then 907 mill diff if you can get away with it. Once the diff jumps up to 1.2 or 1.4 bill then mine for your customer.
Aren't there some big commercial mines online now as well? I'm not sure if these have any bearing on the increased hashrate but ASICMiner had that liquid Freon cooled datacenter https://bitcointalk.org/index.php?topic=346134.0 The Bitfury teams seem to have been expanding tytus' mine as well and thats running at near 600Th |

Seeing as no-one else seems to have mentioned them, are these grey sponge type things in there for any reason other than shipping protection?  I assume they are to be removed...? I removed one just now. They are the thickest thermal pads I have ever seen. Not sponge. I'm assuming they think that they are transferring some heat to the metal bar which in turn transfers heat to the heatsink and fan. But I can't see how it would work. I've removed one anyway from the one I could reach at the back of the system. I'll keep a close watch on the temps. |
