How about a panoramic?
damn i have an asic 'boner' crosses legs how much is all that (braces self may 'swoon') I really love that rack. Well organised, clean etc. I really hope one day I would have one like that too! There is one thing that - as a network / dc tech makes he tick. Why the different color of cables? - my OCD hopes its cause some are customer ones and some are your own  While I don't have your OCD issues keeping the colors the same, my ADHD issues make me need to have each color be the same length lol! Polar opposites :-D Well, at least I'm not bi-polar right? |

My Dogecoin Station  I saw that, and that's why got me to put my little one up... very nice. Can I ask where you got the USB hub that has ATX in and a switch? About the power supply, I'm switching over to an ATX power supply once I get the adaptors... Hello, That orange USB Hub is one of the best ones out there! A block-erupter hub is not coming close to the quality of this one. I got this one from eyeboot.com Deeplink here. I only use this hub`s for my projects, For example the block-erupter hubs use give me a lot of problems whit stability, or just died within weeks due to bad components  Check this picture "loaded whit miners of 1.2 Amp each", no other (still affordable) usb-hub stays stable whit that kind of load.  Hope your question get answered here. That's pretty :-) |

9 hrs after initial shutdown - miner begins beeping... 10 other rigs are not affected
powered down, powered up. IP is ok but 0GH & 61°C
tried connecting to gui - nope
powered down, removed sd card, powered up - blue screen
powered down, reinserted sd, powered up - mining...
wtballs?
I had the same thing happen the other day, it seems one only needs to eject and reinsert the sd card and it'll boot. I've not needed to re-image a card since (I'm wondering if re-imaging was even necessary in the first place)... I had a plug trip last night and was faced with the S2 "blue screen of death" after restarting. I just ejected the SD card and pushed it back in and it booted up no problem after that, no need for re-imaging  I pulled the image of the SD card after the corruption. I took the card and used win32diskimager to pull the image. When I looked for files on the card, I didn't see any. Here's the image: https://dl.dropboxusercontent.com/u/16075357/CORRUPT.IMG.zip |

IMPORTANT UPDATE! Just received CCTV footage of the KNC 5% mining farm. They've added a 2nd and 3rd level to the shelving, so they can stack the miners 3x as high. The indecent below shows what happened 1 day before they decided to offer "sooper Jupiters"  |

I think it's perfectly okay for bitmain to mine before selling and shipping. It's not like you paid them money for a preorder and they use your money to build miners, mine on them, then ship it to you months late.
Bitmain is different than other ASIC's companies. They are trying to setup a win-win situation for themselves and customers. Sounds good to me.
you are joking right? tell you what, next time you go buy a new car, just let the guy on the forecourt take it home to his wife, 3 kids and 2 drooling dogs for a few weeks first. I can't believe you seriously said that. please keep whatever you are smoking, to yourself. I don't give 2 licks what they do with the hardware before they ship it. If they ship it when I order it and it works and keeps working, that's all I care about. |

I know it was talked about earlier in the thread - but I have not been frequesnt the last few days and am planning to visit my S2 for the first time tomorrow morning. 1) Should I reflash the firmware of the unit AND/OR copy a new version of the SD card? (I saw an SD image posted a few days ago) 2) I am changing to a 2kW server PSU and want to see what sort of overclocking is available. How can I change the clocks? I saw several posts indicating that the unit clears the settings at a reboot, so when changing the clocks you have to start/stop the cgminer only. Can someone post the code for that (using putty SSH and I have experience with S1) 3) overclocking, the hex codes are the same as were listed in the U1 documentation? https://coinreport.net/overclock-antminer-u1-guide/ is correct? (the initial clocks are 160-170MHz right? I would be aiming to 212-225MHz to start. 4) overclocking, do the stock fans get fast enough to handle it, or will I need to pull the top off and add a pair of 230mm fans to increase flow? I could run the PSU outside the case to lessen the heat created An OC to 225MHz shows 1147GH/s on the miner, but less than 1,000GH/s at the pool, basically the HW errors are so much higher you get a lower effective speed at the pool. Hoping the community can figure this out, maybe a firmware update or a more optimized CGminer. |

Bitmain is the only choice for Bitcoin Mining
Why do I say this?
I have purchased 267 Antminer S1's. Out of 267 S1's I have had 1 problem unit. One unit with a dead ASIC blade. That's it, 99.8% success rate. That's unbelievable. They just keep running, and running smoothly.
I have purchased 27 Antminer S2's . Out of those 27 S2's I have 1 blade that only half worked (From batch 1. The heatsink had a burr on it that cut into the board and shorted out half the blade). I also had 1 power supply that melted as the cables weren't connected tight at factory. While batch 1 had a good amount of extremely irritating issues, batch 2 was much better and batch 3 was nearly flawless (A few loose internal cables). I have been in contact with Bitmain concerning all the issues and they are indeed working to correct where they have come up short.
I have no doubt the S2 will soon be just as rock solid as the S1, and as you can see form above, the S1 is gold standard in ASIC hardware.
1l1l11ll1l, batch 3, where do i find that? It was more like batch 2.5 Batch 3 isn't released quite yet. I'm sure Bitmain is in the zone building machines like crazy so they can immediately ship Batch 3 |

I have just received the second batch S2 today (in Spain) and the unit was totally destroyed.
i op
So I have to put all the boards out, put by force all the bented pci slots and fans connector right again, connect every fan, pci and even the ethernet connector from the beagleboard to the fron of the case. Then one by one put back the boards, but as you can see in the pictures one side of the boards holder is totally destroyed. I don't know who the smart at bitmain has designed the boards holder, but holding so much heavy boards by plastic holders that can be taken out so easy from the chassis is just ridiculous. Why you build so strong chassis if you then put plastic holders that simply pop in the holes, not even with a screw ?
Now what, some type of compensation ? At least a replace of the broken piece and some compensation I expect. I am lucky that after all the miner is hashing right at 1-1.1 TH/s
You're definitely lucky that it's running at full speed! I have to say though, I've never seen the frames bent so badly, yours had to have taken one (or more) serious blows. Even if the case had been built more sturdy, I don't see how yours could have escaped some damage, the metal behind the plastic guide rods looks like... well like:   |

hello all the lights at mainboard of s2 is on and antminter does not hashing all fan is full power but nothing what might be the problem? also how i can do hard reset at s2???  You need to reflash the microsd card with a fresh image. See my post history for links to image file, use win32doskimager |

this is a new level.. box w fans and psu inside (check the cable endings)  These generate power while running, the aux power out cables are for your KNC Jupiter, for example. |

Payment is either with Bitcoin, Bank Wire Transfer, or PayPal. Value based on current Bitcoin Value of Coinbase.com in USDA

Its so fake its not even funny,
Does anyone notice there is one row of A1 chips on each board thats completely not on the heatsink? lol.... are they like only for decoration?
That's Patented Technology, sorry |

Yeah Ntek, I can get Antminer S2's on ebay for $4k/TH and hash this weekend.

That is crazy. Are you still mining with all 77TH? Do you personally own all 77TH or is this hardware shared as part of a mining group? I have 20 S1s mining right now, and all work flawlessly, so I hope Bitmain addresses the S2 quality issues and offers a new competitively priced batch of S2s soon. Bitmain not only offers a great product at a fair price, but they are also putting an end to a lot of the shenanigans pulled by other hardware manufactures by forcing them to alter behavior in order to stay competitive. Just say no to pre-orders! Mining on most of it. Bought some for family/friends http://eligius.st/~wizkid057/newstats/userstats.php/1487GbVKfL1Yq1N9ih6v58QWvsmwpNcBvg |

I'm not disputing the greatness of the S1 (or the S2) - just the ability to make any profit at 0.8ish coins. A drop of 0.01 every now and then is not going to make any difference to that fact. That's why I said we need a step change in price. Even at 0.45 BTC per unit and difficulty remaining the same as it is now (which it wont) and having free electricity (which most don't) - it would take 38 days of solid mining to break even... Taking difficulty and electricity into account, you are looking at 2 months. At 0.855 BTC, well, you do the maths. Where else can you break even on an investment and start making a return in 3 months is the way I see it. |

How in the world did you get Batch 3 when they haven't released it yet?
It was more like a batch 2B but people are referring to it as Batch 3. correct. |

New price for AntMiner S1: 0.855btc each one, shipping cost included.
These really need a step change now bitmain - drop to 0.45 and they'll nearly be worth buying again. Unless Bitmain reveals his true shipping costs its hard to know exactly how low he could go and still make a decent return. No one should expect Bitmain to give these away! All s1 are tested but for how long only bitmain know. why you think they still keeping price like that? they mining to the max and once enough btc is done they flush miners on us. Not sure, I k now I have received some that have definitely collected dust, but I've also received the majority that were new and fresh. I think they do send out refurbished units. While I don't personally condone sending out refurbished units with new units, the bottom line is they are tested, they work and the have the same warranty. Without a doubt bitmain is mining on their machines, they'd be crazy not to. It almost seems though, that in order to process shipments as quickly as possible and to mitigate delays that might happen, they ship from their mining farm immediately so that a delay would only cost them mining time, and not the customer. |
