looks like a US plug tucked away there at the side...why do we need an extra usa adapter for $1 usd then?  yeah, you can kind of pull it out at 90 degrees angle with pins probably of "asian" type, therefore you can just go to any mall and get the "international plug" for it. |

Hello my friends.
Im new in mining and im waiing for my S7. I did my own math and since i've got free electricity (i'm lucky... i know) the business is good.
One doubt about the S7 Fans, anyone has the specs?
Im thinking in changing the fans for example NOCTUA NF-F12 PWM 120mm Focused Flow PWM Cooling Fan.
Do you think is good idea?
Thanks in advance for the help.
Why the desire to replace the fans? If you expect to reduce noise by simply putting in a quieter fan, plan on substantially reducing the hash rate as well. Bitmain didn't put LOUD fans in on a whim. It takes serious airflow to cool a 1200W heater (i.e. the S7). The fans Bitmain chose push a lot of air, with enough pressure to get it through the dense heatsinks inside the enclosure. I'm running my S7 @ stock speed @ 2500rpm fans @ 30C ambient without issue. Its not inconceivable that one might be able to do the same after replacing fans given a lower ambient. Also worth remembering that both the ASICMiner Tube and Prisma cooled ~1KW through a longer heatsink using a single fan. And in the case of the ASICMiner Tube it was possible to replace the fan with 2x Corsair SP120s which are quite a way under the NF-F12s. interesting...what is % setting and its boards temp? thanks what temp is the room. he said it is 30c ambient, which i assume is the room temp. |

What things could happen with the btc price when the block halving occurs? will the price go down due to miners cashing out? or will the block chain slow down due to miners shutting off their mining equipment? will the price go up because of less daily bitcoin created? what will likely happen?
Miners would have to sell more as the rewards are less to maintain their operations. they cannot sell more than they mine |

IT only draws 24 watts...
I don't get it this thing SMASHES any repeater on the market as it costs the same.. draws the same BUT MINES for you..
1. consider shipping costs-negative or get from a group-better 2. it does NOT mine-it gives you a chance in a lottery, which with your miner being ~1/100000000 of the network, would work out for 1 block in ~200 years at the current difficulty. However, it also means that for every 2000 sold and being deployed 24/7, one will score a block within a ~year on average (with current difficulty), but the other 1999 will produce NOTHING. I did a rough estimate-numbers could be off, but it is what i got. #2.. that IS MINING........................... Mining with a CPU back in the day was like this... It 100% mines. It costs $16 to ship it with out the convertor. It does everything a repeater does but mines as well.. I need to repeate the wireless signal in my room.. haven't bought one yet, why would I buy anything but this..? Other device, repeats interenet signal, costs $40cad, draws 24ish watts.. THis device, repeates interenet signal, costs $40 cad, draws 24 watts, SOLO mines bitcoins. I don't even want it on a pool.. that is what my S3's are for lol. i am not saying that you should not buy it, i am saying that you can disregard the "mining" function of it. I would have preferred $3/year truly "mined" instead of a 1/2000 chance each year, but to each their own. second, I don't see a separate cord with a plug, so i assume that plug IS needed (device will not work without it).Edit: probably not as there is a pull away plug-see pictures from cybtc below. |

Guess it's time for some Black Label and try to forget about the $$$ sitting at a chinese company.  I am a red wine guy, but if it is time for something stronger, then good vodka would be my first choice  . |

Perhaps well as it is was left hanging out to dry this round ha-ha guess it was a tad to soon to call that.
Bitcoin Difficulty: 59,335,351,234
Estimated Next Difficulty: 60,677,521,610 (+2.26%)
Adjust time: After 177 Blocks, About 1.1 days
Hashrate(?): 463,788,308 GH/s
so, you are telling me there is a chance... https://www.youtube.com/watch?v=-9IgLueodZA |

Afaik this supports 3 main uses:
A) basic WiFi network for anyone who only has a wired network/modem.
B) novelty/collectible/"lottery device" for non-profitable mining
C) if it can connect to WiFi and act as wired access point it would solve the griping over lack of WiFi in mining hardware. You place one of these and a network switch in your mining farm, and save yourself costly ethernet installation through the walls/floors of your home
If it does the wired AP or wireless repeater effectively though, it could be a decent device useful for more than simply mining
A) yes, but it depends on how well it plays with third party devices, including larger routers (like airport extreme). if it could be used to extend the network-fine. B) OK, but not sure how practical it is-how it is tabulated so you TRULY have a chance, and not just give your hash to antpool. They have to explain this better. C) I suppose, but i use airport express for it-it works pretty good and was able to support at least six-seven devices via an ethernet hub. |

Read btcs news from sept 28. They had to lease their own (SPT) equipment. I am not sure about the rationale for it.
eventually, they will probably have to either borrow money or do a preorder to start producing these units in bulk.
Called it 7 months ago when they demanded they get a "does not use preorders" rating. - We don't rely on pre-order for our next gen. I can't even begin to count the number of times I've said it. It's not our main business model. I even took the time to explain to you our business model for our next gen. Yet, you keep claiming that "you continue to do as your main business model". This is simply a lie and you know it.
Can you afford generation 3 without selling preorders, raising millions of $ or using 'investment' orders? Its a simple yes or no.
If you're asking if we can afford our entire gen3 planned capacity without injecting more funds via additional investment or pre-selling mining capacity to accredited investors, the answer is no. The same goes for every other company in the space. For the last time, since you seems to have difficulties in understanding: we'll not sell our gen3 products to consumers without proving the technology first. Afterwards, we might, but then it won't be pre-ordering. It might be selling by batches.So tldr your current business model / situation can not support generation 3 without preordering (/ preordering under another name) or some miracle investment. Under no circumstances could those statements EVER qualify you for running a business model that can get by selling purely out of hand. The way i see it-situation might have changed or NOT. I am simply calmly discussing what various moves mean, not passing judgment on what was said before. Spondoolies did take good care of their customers like myself-I have nothing to complain about. |

I will get a new batt for my multimeter and do some measureing for you guys.
My S7 is running stable at 4.8 at 600. Power at wall 1180. Using a RM1000 and a RM650
Mine only got to 4.7 at stock speeds. But at 612, it averages 4.8 and is very stable. After increasing the frequency the HW errors went up a bit from 0.0222% to 0.0386%, but that's still fine. Overall this unit is very stable and predictable. I just wish they could have shipped the rest of units that I ordered before getting plastered on baiju for a week  interesting. on my machine: 600 starts OK (4800), then rumps up slowly over 12 hr to ~4840 <=0.006% error 606 starts good (4900), then slightly declines over 24hr to 4886 and stays there (5 days) 0.0068% error 612 starts super (4990), then decreases to 4915 over 24 hr (maybe would have kept decreasing, basically negating the higher freq) 0.0088% error strangely, at all frequences board temp are 52-53C (fluctuating between 51C and 55C) Conclusions: 1. it takes a long time to truly settle (>24hr), so I suggest to not reach a conclusion based even on 1hr as it might change. 2. temp do not depend on frequency much (this is strange), but probably correlate with ambient air temp (mostly). |

I wait until someone publishes a hack, so I can produce some dust on another pool...
yeah, $3 in a year |

still no word on the prices?
nope not yet. All silent on the front Looks to me like Bitmain reduced to some extent the top possible price, since they lowered the price of Batch 2 & 3 of the S7. Spondoolies would seem to have less room to maneuver now in terms of price (IMHO). this. The SP50 would need to price in the range of 120-150BTC to compete 30K max realistically, but 25K is optimal. If you haven't noticed, BITMAIN adjusted its pricing for batch 3 S7's in relation to the time before block halving more than the difficulty. Batch 3 S7's are at $1,658 instead of $1,823. Each month that passes by before the block halving apparently is affecting the price of their rigs with the price of bitcoin virtually unchanged. So, if Spondooliestech does not want to miss the boat for selling the SP50 with optimal returns, they might want to have them up for sell relatively soon. It will be interesting to see how the block halving affects the pricing of rigs [If at all] as it approaches. Read btcs news from sept 28. They had to lease their own (SPT) equipment. I am not sure about the rationale for it. eventually, they will probably have to either borrow money or do a preorder to start producing these units in bulk. |

Sold out of US power adapters for the R1, I was going to buy five and leave them around the house and work. How can you run out of the adapter.....
What kind of plug comes standard on the R1? Are there other places to buy the adapter? I am afraid that nothing comes standard (no plug included as default) as there is no description of any electrical connection apart from the plug. |

Good that it worked, but it is not exactly a new behavior for antminers.
In fact, S1 and S3 on many machines also had errors with PSU hard reset and had to be rebooted into a "better state" by a software reboot and sometimes multiple of those (especially on S3).
I am interested in some other parameter-what is the optimal board operating temperature that miner is reporting in gui.
Somehow it looks like it throttles back by itself as soon as it reaches 56C or so, at least on my machine.
i don't see much difference in hashing at 51C vs 55C with ambient around 28C. I wonder what others had observed.

bitcoin: 10k-100k
ltc:1k-10k
mintcoin: 1-2 dollar
doge: 1-2 dollar
novacoin:$100-$1000
gold: 10k-100k
silver:1k-10k
dollar: .05c-.10c in today's money
taco: 20 dollars
gas: 150 dollars/gallon
if gas will be worth $150 and dollar worth 10c, it would mean $15 gas in todays price parity. If this would be the case, Houston's average house would be $1 mil in todays prices (or 10 mil in prices that you predict if dollar is worth only 10c) from current 150K, making it by far the best investment as you need only 5-10% downpayment. Hmmm...maybe I should buy some RE...NOT! |

my miner came quickly, but it runs slowly.
i can not get past 4600 and errors are .1100
sorry to hear this, but I thought that you got a couple. is second similar to the first one? |

Xian 1
I dit just the same and it came out very well.
But i miss a miner in the house.
