What am I missing here? 0,25$/GH wth 1155 means 288,75 USD. Bitmain's site states 369 USD ( 1.279 BTC )
you are missing that they don't care about this (since they never corrected it) BTW, it does not matter anyway since you ALSO pay for shipping and that 0.25 number never included shipping anyway. |

Can you give us figures of actual db from the miner, especially compared to stock? i know some reviewers were saying at 4 ft, stock fans on the S5 are around 75 db. i'm very interested since I have my 2 s5's and an s3 set up in an office where the noise is just unbearable
I did use Noctua in push and Scythe Ultra kaze in pull. Two Noctuas/miner are expensive. Both together gave ~55 dB vs 73-75dB for stock at default speed. It was still a little annoying in the office, but totally fine in another room. if anybody wants, I have two Delta AFB1212SH-PWM fans which i don't really need since I sold my S5s These seem to have similar(if not better) air pressure and CFM to Noctua and they are less expensive (advertized as 46 dB, but typically i don't believe these claims) http://www.newegg.com/Product/Product.aspx?Item=N82E16835213011 |

I read somewhere that if all the currencies around the world (USD,GBP,Euro, Peso, ect) were to be combined and Bitcoin was given the same value as that, then one Satoshi would equal around .02 cents. So no, I don't think one satoshi will ever be worth $1.00
why only count currencies and not assets valuation? i think assets are into hundreds of trillions Total GDP is 30 tril/year Total Earth value is apparently at least 1.95x10 17 or 195 quadrillions: http://en.wikipedia.org/wiki/Value_of_Earthtotal number of satoshis=2.1 quadrillions so, value of BTC at sat=$1 will be 1% of Earth value One can also possibly imagine in >200 years, people forming sidechains (to remove btc permanently from earth-based blockchain) to buy things on other planets (blockchain info cannot be readily synced with planets light years away) |

i don't appreciate that the site if sniffing my browser before connecting. Sniffing your browser? It really doesn't care much about your browser other than whether or not it is capable of some simple string manipulation and math. It's the most basic level of defense against trivial DDoS's. ( It's sufficiently basic that a bot I wrote happily grabs the challenge, solves it, submits it, gets the cookie, re-accesses with the cookie, and grabs the data, then re-uses that cookie until the site decides the cookie expired and it starts over again. I'll have to see how it fares with bitmain's site. )You're sending vastly more information to a site about your browser just accessing a page in the first place. Why do i need to see the message that the site is checking my browser for DDOS? I certainly do not need to see that snippet-it should be done in the background. Is this your first exposure to cloudfare? This is the way it works dude. never seen this message before, although i am pretty sure many sites use the tech I've seen it many times. I don't know why people want to tolerate crappy web interfaces, but whatever (imagine google telling you on a blank page what tech they use for your web search-that would be a riot) back to the main topic: that cancelled transaction (EDIT: post is now gone) will be manually changed to paid by tomorrow (I have seen it multiple times) If you still feel unsure, send email to info@ with your transaction number |

You want to think your browser is just freezing while making the check? Get over yourself. actually, it takes roughly the same time for me as bitmaintech site is quite slow for the initial load, so there is no time difference (at least for me) why being so defensive about a minor comment? |

We sold out all of our 2nd gen miners.
Congratulations! I hope we will see a price increase in the second hand market! I second that, but it is not happening so far  . I found it amazing that nobody had created anything like the SP3X series in almost a year. Great job from SPT. Cheers |

Site is offline again. It is crashing when I click the 'Add to Cart' button
EDIT: Working now.
Its likely an effect of the DDOS, site is on cloudflare so any outages should be very brief. i don't appreciate that the site if sniffing my browser before connecting. it is not cool. if every site would had that annoying message, people would get upset. |

Running the chips cooler on my SP20's (from auto fan and chips in the 80's-90's to setting fan to 100 and bringing chip temperature down to 70's) resulted in about 3% lower power consumption for the same hash rate. Cooler is gooder my friends.
One has to wonder how long fans can operate at 100%. I just don't know. |
|

How about the SP30?
I have it running in an air-conditioned but small room, at "slow fans, medium rate" setting (Fan Speed 60 Start Voltage 0.65 / 0.65 Max Voltage 0.73 Max Watts 1100 / 1100), my temp readings are Temp Front / Back T,B 32 °C / 68,79 °C. I had it running on "medium fans, high rate" for a few hours, but the last temperature number was around 85, and for some reason the miner restarted by itself (maybe reached cutoff temperature?)
And what do "T" and "B" on the back temperature mean?
we were talking about asic temp readings (visible on ASIC stats pane), not exhaust, although exhaust 79 is high. |

Off-question, but what are the 'safe' temperatures of the SP20?
When looking at the Asic stats page, LOOP3 is always the hottest, even if I set the max power supply watts lower than the others. (At 150 now).
Seems to like to climb to 80C. The others are in the 50's and 60s.
Thanks
sp20 shows real chip temp while real temp in s5 is actually at least 20-25C higher than what you see on the interface if you choose auto and high enough power and voltage max limit, miner will bump the temp and drop the fan until the highest temp reaches 115C, suggesting that it is the highest steady state temp spt is comfortable with. |

What I mean is, his revolutionary design was a string miner. I was being sarcastic about it being revolutionary, since folks had made BitFury string miners a year before. Strings are good because of fewer parts count and increased electrical efficiency, but the lack of voltage regulation and adjustability sucks. So there's still room for improvement.
By many I meant quite a few other people who were regular on this board posting that S5 string design would never work, will be constantly throwing whole boards off, etc, etc. Largely, it did not happen. I think that we need an economical new home miner before 21e6 will introduce their product, whatever it is (I strongly suspect that it is a router). |

Not yet, they haven't even shipped chips yet. I did finally have some progress on the other thing I've got for you, and will continue to refine it today. Hopefully by next week I'm able to send a prototype.
It'll be a couple weeks before I'd have a miner, probably more like a month. I'm leaning on Novak for the firmware, but we both just got big jobs came in over the last week so we're both busy in different areas. I hope I don't have to do all the coding myself, which is possible but he's the better programmer.
Did you try to contact that legkodumov fella who designed the string board Bitmain used (they mentioned it themselves on some obscure board here). EDIT: found it https://bitcointalk.org/index.php?topic=728068.msg10435170#msg10435170I think that this guy was saying that he can give the design to anyone with chips (maybe for large volume, though, but it wouldn't hurt to ask). No I didn't. You may notice from reading that thread that I was cynical about his design, given that when he posted his revolutionary idea there had been several other string-based miners already come to market. Between Novak and I we have enough knowhow on the hardware and software to do what we want to do. Bitmain hasn't shipped chips yet because I forgot to send them payment yesterday. Regarding PSUs, if he's running 1400W from a PSU and then adding one fourth of an SP20, he's looking at adding probably about another 250W so that puts the supply at 83% rated capacity (or about 69% what it's actually capable of). Might be alright. sure, better design would be beneficial, although many were skeptical re strings and they seem to work OK (at last in case of S5). |

Internet of things is the first step toward machine AI that would be totally independent at some point.

wtf is a gucci edition psu?? i cant see any info about this so please explain y ur listing a corsair psu for almost 1200 bucks?? im blown away by the prices in this thread and then i hit that item listed and i nearly fell outta my seat lol.
that is on pokeyjones-ask him. One SP20e is still on sale. Price reduction to 1.9 BTC=~$563 ya i doubt he will be back and i think he was being a smart ass ne way but still i had to ask just in case he sees it. thats alot for a sp20....i paid $350 for mine.... S5 is $466 shipped to US for 30% less hashing (at least 1.5TH conservatively for SP20 vs 1.15 for S5) AND S5 will be shipped in 20 days (you can mine quite a bit during these 20 days). This machine (SP20E) is ready to go. |
