Wasn't the pricing 99 Yuan? DHL shipping would be ridiculous, but at least it would arrive before the end of the quarter  (china post is not exactly the fastest option) you dont buy this for the hashrate. Its like buying a 1GB flash drive for your 10MP camera |

Ive been having trouble with my bitfury staying connected to the pool during the last 2 days - it is constantly dropping to zero hashrate from anything from a few minutes to a few hours. http://eligius.st/~wizkid057/newstats/userstats.php/17ztqVKWEg1j25D3AoX87W66rYJApasPLKthe interface for the miner says it is stable and never reflects issues. It seems to work again if i click 'start miner' but that isnt solving the constant ups and downs Use thier Kncminer port, its 12234 I think, it starts at a higher difficulty. I have run my miners on it the last 4 days and its been stable. I would verify that port but the eligius main site is down for me. Hmm, you know I was thinking of doing that myself but never got around to it thinking that the their dedicated kncminer port would not start with a higher diff but do some other magic. I shall try that out with one of my bitfury rigs and see how stable it is. Thanks for the tip!  I hope it helps. I think Dave should let us Mine at his pool since all the other pools have issues with Bitfury. ghash.io is reliable for bitfury devices |

I can submit an order if I damn well want. It doesn't say you have to pay it all at once nor do I even want these useless units since the price per Bitcoin is now under $450 a coin. It's not my fault Bitmain's Bitcoin to USD price is depleting every second.  They are priced in btc. most of us calculate profit only in btc, there is no reference to fiat on the site.. if you dont have the coin, or balls to pay in full.. the gtfo Hey asswhole. I can do whutever the fyck I want you arn't the fuckin Boss of me. IDOn't want this fucking unut which is why I want my fuckin money back! Kindly eat a bag of dicks as you are not fuckin Bitmain and have no fucking say in this... >  lol.. and now we know why your profile has so many colors.. maybe I can help with a little orange, welcome to the iggy button Hey faggot find me someone that cares ok? ^looks like you care.In less than 3 messages you went from reasonable to completely offensive maniac. welcome to my ignore list as well |

my bitcoin-qt is virtually useless as it is including mauled transactions in its balance. blockchain wallet is fine though.
however, its been 22 confirmations since i sent a deposit to btc-e, i have no idea why it isnt added to my account yet

I'd like a refund for my orders please. Username is CrazyRabbi Please cancel my orders and send the coins back to 15STm6e6F47fYgyVPRCAnu5Av9JQpx3eBn Thanks in Advance, CrazyRabbi PS: I've emailed about this several times with no response wow - anyone who looks at your trust feedback will see that all his feedback (given and received) is negative and very unpleasant. seems fitting he would try to back out of an agreement with bitmain and demand refund on units that likely shipped already |

I asked for pricing, and with the suggested DHL shipping the costs were rediculous.
0.03BTC per unit before shipping is too much. I would pay 0.05BTC for 2 if that included shipping simply due to thier novelty value and to see whats inside, but anything more than that is just throwing away money on something worthless

It seems to work again if i click 'start miner' but that isnt solving the constant ups and downs Ha, welcome to my problem all along.., I so far only have been running stable on BitMinter. Al other pools I've tried it runs for a few hours then pool reports it's at ~3GH/s (from 350gh/s) Have not been able to resolve it either.., even with auto restart of proxy and miner timers. Eligius has an issue with Bitfurys chminer. Went into the IRC channel and they acknowledged the speed flux issue, and have no workarounds or fixes. I pointed a rig there and wasn't getting good speeds. Even tried to set the cron to reset every 10 minutes but that didn't fix it. Ive had weeks of stable operation though, with maybe tiny blips here and there. today though, the machine is only getting about 50% uptime compared to its usual 256GH average for 12hrs I am getting ~123GH averages for the time period. I need to resolve this asap or it will be back to ghash.io EDIT: NOW I AM REALLY CONFUSED. I changed my pool config data to disable eligius and enable only ghash. Its been almost 8 minutes and the bitfury webUI shows hashing at 240GH and the modified pool info, but theres absolutely no activity on my ghash account OR my eligius account. Somehow chainminer seems to be hashing without a set desination EDIT 2: LOOKS LIKE I NEEDED TO STOP AND START MINER hashrate now showing at ghash.io - if there is still any issues I will report back. Its unfortunate that it was acting so poorly on eligius |

I can give you TXIDs, but you won't be able to find them... so whats the point of it?
I am using bitcoin-qt, RPC API for everything related to BTC handling, and of course, integrated accounts in bitcoin client.
I checked bunch of transactions that were made by same customer (person X) going to same rig provider (person Y), and were only few or even less minutes appart. There was total of 8 transactions, 6 were at the end confirmed, 2 are still not and pending (since 12.2.2014 20:45 CET time). After these transactions, same customer hired other rigs some hours later and these transactions were then confirmed. Does that mean that it is safe to assume these 2 non-confirmed transactions will never be confirmed and should be deleted and resent?
I am having a similar issue where a txid cannot be found on blockchain even after almost 10 minutes. I had a malled transaction before, so perhaps my address balances are all out of sync. what can/should I do? |

hoping for a price drop - I would order 5-10 units if so
1.45BTC is no longer a good price

I have been given a potential spot in the back storage area of a small business. The area is warehouse-style with high ceilings and enough space that some can be given to this project to undergo the first stages of trial and growth.
I expect to look at the available location no later than monday. It has a 45KVA transformer (from 600V), and the office itself likely draws less than 15kW even with AC. The fuse panel looks like installing additional circuits wont be a problem - this means that a solid 15-20kW should be available for hardware. (If this is reached, then either a transformer or location upgrade will be in order
After that, my next steps are
check the network suitability
look into power smoothing and UPS
determine available space and start bringing in shelving, IP security cameras, and potentially installing a security cage if necessary.
For a short-term location this should be quite sufficient, and the rent will be quite low - hopefully a reasonable amount of space for ~$300/month plus power and potentially some upkeep costs (There are a few savvy employees that may be capable of performing simple tasks such as daily inspection or rebooting units/updating connection info in order to reduce the need for me to visit the location if something is up with a machine). If you factor in power costs and the above, hopefully can do this for <$0.20/kWh (at least until AC becomes a necessity), and potentially a small installation cost to share the up-fronts

Yes, there's a reason many oem's are pulling out of retail. There's tremendous workload associated with providing quality customer service, a solid refund policy and fast shipping. Adding credit cards has increased our administrative costs due to the amount of credit card fraud. In order to honor refund requests, I've sent millions in BTC and USD. In addition, the presale market continues to set lower bounds on price, despite the fact the we ship and they dont. Price fluxuations in BTC drive ROI models crazy, putting pressure on us to lower prices. Leased haspower is at least currently demanding an attractive premium over offering retail.
MBP was and still is focused on building mines. Retail sales has been a great way to involve the community, and initially generated some good capital, though we haven't done anything like the sales of KnC, Cointerra, etc. and in the face of 28nm, our product has become "legacy" equipment already.
All this being said, we still have an idea of what we are willing to sell our hardware for, and that is reflected in our prices. I dont typically respond to price wars, nor do I ever engage on forum arguments about ROI. The price point each miner will pay is a personal decision and everyone has a different strategy.
If my prices don't appeal to you, I encourage you to shop around! But I hope this is not perceived as a.lack of support to the community. I remain committed to bringing our next gen products to this community along with continuing to field the best customer service and support team in the market today.
good points, but it doesnt make your product any more attractive then an antminer S1. I just know that when I am buying my next 1+TH of equipment it will be from them, because the product does the same thing but at a lower cost. MBP deserves a premium for their payment options and FedEx delivery speeds, but not what it is now. A ~35GH card costs 0.5BTC - thats a price more than twice that of Bitmain. However, its your store and clearly the current sales numbers are sufficient. If thats the case, then by all means continue making money - just remember that you could get many more sales at a lower price-point |

One of my 6 ants is hashing with one blade only.
So its 90 ghash instead of 180.
I reconnected all the connectors and I know that the PSU and eveything is fine.
Is there any other Idea what could be wrong? OR am I just having bad luck and that one is broken?
what does the status page show? Is the second board visible, are chips marked with x's? take a multimeter and measure voltage on both blades - make sure 12V is present and look fro 1.1V across any inductors and capacitors. Its possible one of the 4 'segments' (possible the 1st from the left) has an issue and wont power its controls/chips |

Maybe this is too simple to be right, but...
Would not running rescan in bitcoin-QT from the time "some time before problematic unconfirmed-change-spending transaction" help?
It presumably would, and a few options such as last 100 or last 1000 might be sufficient. The only concern would be that: a) this would need to be implemented by each client b) it *could* create weak points for an evil trojan/virus to replace and then rescan a false short blockchain - seems unlikely though |

All this is true.. confirmed tx is what matters, but this attack is very annoying. It happened to me again today, but this time the clone tx confirmed first and I had to delete mine with pywallet. I have no problem with that but the regular user probably would. The QT client (and all clients) should be patched to delete or "hide" duplicates. That would make the "spam attacks" a non-issue (other than you can't assume tx id won't change). Agreed. I have similar issues poping up with my QT Everybody is. Not only a visual annoyance but also a potencial pain in the ass if you do a lot of transactions per day, some of your transactions might break because of unconfirmed change. My bitcoin-QT just forced me to reindex the block chain - its about halfway after 12 minutes and hogging my ram. hopefully this will clear my issue where the wallet balance is different from the transaction-log-based balance. I 100% agree that a simple 'hide duplicates' patch would solve the issue |

I think you are misunderstanding.
...
Right now there is no way for an average user to force the client to only used confirmed change in new transactions even if they wanted to, other than manually wait and make sure they have no unconfirmed change outputs before sending funds.
I see what you mean, you are right. Would a simple configuration option whether to show unconfirmed inputs in the balance do the trick? No may be the default option, and you can always go to the console and temporarily force the opposite behavior if you want to. It may not even mess up how QT client handles the blockchain, just how it calculates the balance. Edit: I have to check how it is this done right now in the code. I'm not positive how the balance is calculated. THIS. I compared my wallet balance against the transaction export and found that the two DID NOT MATCH. my hot wallet is 'richer' by exactly the amount in the second transaction's change wallet - I am not 100% sure which total is correct, though I imagine the wallet balance is the correct version EDIT: my client just forced me to undergo 'reindexing blocks on disk', a process that appears to be going to take ~20min |

actually got in touch with bitpop who offered his service. thanks to all you guys who replied though - I will bookmark this thread for the next time i need escrow ps: I am also willing to offer escrow to others if they are inclined to choose me - obviously though that makes no sense for a transaction in which i am a participant! |

So what do you guys think, will I be able to overclock Two Antminer's with this PSU? Or am I pushing my luck? It peaks at 825W  I'm not sure if 60Amps will be enough to run 2 miners, but I've not run 2 on my 750W yet (been working through other issues), although it has 4x40Amp rails which would probably be better suited. If I overclock both Antminer's and it turns out to be too much for the PSU to take, what is most likely to happen? It will just power off right? I won't destroy anything right? if you are pulling 400W from each miner, overclocked, it won't work. Yes but my Power Supply has a peak rating of 835 watts, and cost me 200 dollars in 2007. I'm pretty sure PC Power and Cooling isn't some joke PSU maker bro. So you will run your PSU at peak continuously? What is its efficiency at peak? Not sure what the efficiency is, but I know PC POWER AND COOLING is pretty much Master Race as far as power supplies is concerned. When my antminer's arrive from China, I'm gonna blast this fucker with all she's got, I'm talking 400+mhz here. Hopefully I'll save 100 bones too. seriously, read the box properly. When it says 750W, peak at 825W it means that the 12V rail can be maxed out at 60A (720W) for a short burst of time while the 5V and 3.3V rails also draw their full powers (another combined ~105W). You SHOULD NOT run a PSU 24/7 at the full rated capacity. You CAN NOT run a PSU 24/7 at its maximum (short-burst) capacity. You would burn the thing out in a matter of hours, days if you are lucky. you have 60A on the 12V rail. This is 720 Watts. I would not advise loading more than 680W on this so that you have a little bit of leniency from the PSU. This means that you can only run 1 antminer per PSU, or 3 antminers between 2 PSUs |
