The three from my customer are capped at 1100W, as per Zvi's recommendations. They're each hashing stably at around 3950 GH/s. Currently, I'm seeing 3923.69 GH/s, 3951.675 GH/s, and 3982.555 GH/s. These three are all running 2.2.35.
This simply isn't the advertised (after adjustment) 4.5TH. WTF? Is spondoolies trying to lower the rate still further? 6.5Th -> 6.0TH -> 5.5TH -> 4.5Th -> 4.0TH. Where does this stop? 4 is about 60% of 6.5. That sucks tremendously. That is not a simple engineering estimation error. That is a major defect. Product was advertised at 5.4Th/s. The 6Th/s was an added bonus and not available for long and for many customers. SP10 had a drop in hashrate on 110V so it was expected to be the same for SP30. The machine can do 4.5Th/s, but you just need to supply it the proper power. |

Also, has anybody else noticed that the difficulty is right around vertical since the last diff change? Have KfC actually started shipping batch 2 ($10k) or is it just ants and SP30 units coming online?
The ant "testing pool" is up to 3% of the network and that is a lot of 441GH/s miners!

It's a bit of everything. Good luck, ants, SP30, Neptunes, bitfury's new DC, AM self mine. We had a smooth July, but now it's time to buckle up  |

As far as I know there are only 1k SP30 units in the August batch so it can't be them. I say it's variance + a mix of SP-Tech and bitmain hardware being deployed.
Where do you get such information? they might have like 10k units under testing... Their capacity production and resources are limited. You can't just build 10k units out of thin air and you need more than 10M-20M$ upfront money. This increase is from Bitfury's DC in Iceland. |

WTC steel was tested for 2000 degrees C and the kerosene's open air burning temperature is around 350 degrees C. You can't have a fire that burns at 350 degrees burn something that melts at 2000 degrees.
Bullshit lies: Max adiabatic burn temperature 2,500 K ( 2,230 °C) (4,040 °F) Open Air Burn temperature: 1,030 °C (1,890 °F) Bullshit lies #2: Pure Iron ('Steel' with 0% Carbon) starts to melt at 1,492 °C (2,718 °F), and is completely liquid upon reaching 1,539 °C (2,802 °F). Steel with 2.1% Carbon by weight begins melting at 1,130 °C (2,070 °F), and is completely molten upon reaching 1,315 °C (2,399 °F) Do you guys even Wikipedia?! Ok steel melts at 1k degrees, but have you read what I wrote? Let me repeat: Kerosene's open air burning temperature is 350 degrees. Please explain how does it melt the 1k degrees steel. |

It's plain useless.
It may be, but I would like to see what are the chances that a guy with ~160Th/s finds 3 blocks in 1 day http://bitsolo.net/pool-stats/No matter how lucky a guy can be its still consider gamble unless you have 1 PH... Pool is the way!!! 4 blocks in a day  |

..., but didn't like the upfront payment and decided to move to Advania even if the price is slightly higher.
I didn't like that upfront 6 months payment either. Would be nice to get temps like you do at Advania, but I've decided to return to hosting with GekkoSci and Mich-Colo. Aug. SP30 unit going to GekkoSci and I just bought (via your Affiliate link another SP30 Sept. Batch 2 which is addressed to Mich-Colo. Although I could look into Toom.im's setup. Maybe when the faster SP30 Oct comes out.. fingers X. Cheers, QG Thank you very much! As a token of appreciation I have added this thread to my sig  Regarding Advania temps I don't know why but a couple a days ago I saw some 26-28 degrees temps and I was shocked, but it was only temporary and while they are not back to 16 they are around 23 right now. |

$45k in 3 days. That's the lottery he is playing.
$45k in 1 day. Amaizing. |

A hot enough fire weakens metal. Jet fuel, diesel or heating oil burn very hot. If there is enough fuel to burn for an extended period of time things happen.
What caused the twin towers to collapse? It wasn't the direct hit from the airplanes or the weight of the airplanes on the structure. Without the extended fire from the jet fuel the buildings wouldn't have collapsed.
If you have an extended hot fire at the base of a building it will also cause a structural failure and then there is nothing to hold the building up.
The buildings that collapsed experienced very unique and unusual circumstances. WTC steel was tested for 2000 degrees C and the kerosene's open air burning temperature is around 350 degrees C. You can't have a fire that burns at 350 degrees burn something that melts at 2000 degrees. |

$300USD per month and locked in for 6 months. No thanks... I wonder how much it will cost after the 6 months?
Cheers,
QG
While it may not be the best or the most flexible offer, my opinion is that it's still a decent offer.Europeans get higher power costs than in the US and the fact that it's a noise-less and heat-less option it makes it decent.I had offers for 500+EUR for hosting an SP30 in a DC I also must confess that I was ready to do with this offer, but didn't like the upfront payment and decided to move to Advania even if the price is slightly higher. |

Pool luck is not really a measure of luck at all. Pool luck is a statistical calculation, like a probability; so for any given amount of hashing speed at a given difficulty level you should expect a certain return. This is like tossing a coin, if you toss it 50 times you should expect 25 heads and 25 tails, although you may not get exactly these proportions.
Your explanations are good and make sense, however they do not take into account that sh*t can and does happen. I work for a private fund that has lost millions over the last 10 years to outfits like Madoff, Corzine, EDF Mann etc. Yet we are still around, which kinda lets you deduce that there must be substantial funds at work here ;-) Those were all bona fide, on-the-level, trustworthy outfits...until they collapsed with a ton of money, including ours. And take note of this curious fact: Money never disappears, it's just that somebody else has it. So, without implying that Slush or anybody is skimming, is crooked, or whatever... You cannot blindly go through life like a clown on a minefield, hoping that nothing will ever go wrong and there is no evil. For someone who works for a private funds you have little knowledge about how bitcoin mining works. A pool being unlucky doesn't mean that someone else is gaining that pool's money. Every pool has the same change of getting a block. What matters is only the speed of the pool in relate to how many block should that pool find on average. Imagine the pools as separate people tossing a coin. The faster pools just toss the coin faster, but everyone has a 50%-50% chance of hitting one side of the coin. Some may hit heads 5-10 times in a row, but they are not influencing each other. The luck is individual. |

Hello all,
There have been some questions concerning our technology and why we are able to realize a power efficiency others can't. It's time to answer them:
Our hashing core is a fully pipelined architecture whereas our key differentiator is a very area efficient custom pipeline implementation which we developed within the last 6 months based on a so called cell based design approach. We combined standard cells with custom optimized complex cells which save area and power.
Our high density core enabled us to realize much more hashing cores on the same silicon area, running at quite low frequencies. The low performance requirements of a single core allow us to apply an ultra-low supply voltage, which is much lower than the standard at this GLOBALFOUNDRIES 28nm process node. Therefore we optimized and re-characterized our in-house standard cell library for such low supply voltages. To ensure that this will work first-time right, we developed the complete concept of this ultra-low voltage design in close cooperation with the GLOBALFOUNDRIES design enablement team here in Dresden, which has detailed knowledge of the selected 28nm technology produced here in Dresden too.
Our unique design achieves in nominal mode 1.4 GH/mm² and 0.19 J/GH. However, similar to other hardware providers, we can change the frequency of the hashing cores in a high performance mode realizing 2.1 GH/mm² at an energy consumption of about 0.29 J/GH.
If there are any questions to be answered, do not hestitate to ask.
Best regards,
Markus
When is the tape out? |

The sp30 is cheaper per GH for both you and spondoolies. It is also more power-efficient an more quiet, so why would you prefer a sp10? I know, but there is only one reason and that's not enough money for a SP30. Lack of 1k$. |

It all comes down to how much time you are willing to accept between paydays and how much variance. Remember bitcoin mining is a poisson distribution ( http://stattrek.com/online-calculator/poisson.aspx ). Lets assume you are not willing to go one difficulty period without finding a block. If you have 1/2016th (0.05%) of the network you should find on average 1 block per difficulty period. Expected = 1 block Probability of 0 blocks = 36.7% Probability of 1 bock = 26.4% Probability of 2+ blocks = 36.7% You have a ~1 in 3 chance of doubling (or more) your return but also a ~1 in 3 chance of earning nothing. That is probably more risk than most miners are willing to take. ................ Please teach me how to calculate the probability of 0, 1 and 2+ blocks per difficulty period with a certain hashrate (1Th/s for an easier example) and for the current difficulty (make it 20 bil for easier example). I have some Jupiters ready for some gambling. Thank you. |

I got this email from this yesterday:
--snip--
Hi,
We are working through the production and shipping queue as quickly as possible. You will receive a tracking number from UPS when your miner has been shipped.
The Neptune Bonus miner is expected to start shipping in August. We hope to provide you with more information soon.
We are working through the order queue as quickly as possible based on the payment dates of the orders. As soon as your order is fully produced and shipped a tracking number will be sent to the email address which was used to register for your account.
Regards,
Liam So in almost one year, knC cut'n'paste customer service email has changed three words - "order" has become "production and shipping". Impressive! Just like the replies for the refund requests were always processed as fast as possible or something like that. Copy paste company. They should change the name from KnC to CnP! |
