S2 received yesterday after ordering it on Friday evening. The boards inside were all jiggled loose during shipment and the case itself was a little bent but everything works fine. I wonder if Bitmain could consider shipping the boards secured together seperate from the case itself so there is less chance of damage from the boards clashing around in the case.
Everything works though after plugging them back in.
I ordered Sat, delivered wednesday to UK... not bad. Has anyone approached bitmain re damaged cases? i have two folded corners and a dent in the top. ......@bitmain ( shouts into the dark ) "Any replacement cases sent out?" Seriously, why do you care? I have a miner that looks perfect, but only 9 out of 10 boards hash. Do you want to exchange? LOL |

You believe that in only 3 years, bitcoin will reach "full adoption" and achieve its full potential in which it becomes larger than a fiat currency. That seems like too little of an amount of time for that type of development (if such a thing could even happen at all).
I chose the maximum value of $1 million because there a plausible arguments by others that justify such a price. My model is about the adoption by people and organizations buying bitcoin. Perhaps in three years half of all such investors/speculators will have made their respective investments. There is a provocative model of bitcoin prices as the realtime unfolding of Metcalf's Law, well charted by Peter_R. I reference it Metcalfe's Law and Complete Triumph of Bitcoin Indicate $100 per Satoshi in 2022Suppose that it takes until 2022 for complete adoption. The Metcalf Model price is $10 billion per bitcoin, and $100 per Satoshi. Hard to believe that now, but I am working on a change to Bitcoin that helps move us in that direction - I believe. Visit my thread in Alternate cryptocurrencies for the whitepaper. So, 0.05 BTC would be a cool $500 mil and kids of the current miners who were donating 0.05 BTC antminer S1 coupons left and right (I am guilty of that too) might be unhappy about that in the future.  It might happen, but perhaps in the 22nd century and not in 2022, though. I would be completely satisfied in my lifetime to have bitcoin valued at $1 mil in current $$. |

Anyone have any idea as to why my S2 is reporting zero as the BestShare?
I'm getting paid for the shares I am submitting.
Thanks!
My pool shows 6 times less btc than I expected and also shows 20% shares accepted. When the machine first started (~24 hours ago) it was at 100% accepted. Is this pool's fault or machine? Any help would be appreciated. Machine shows that it is hashing at semi-normal speed (i have only 9 out of 10 boards functional). Which pool? Eligius Try btcguild. Is this a known problem with s2 and eligius? I had mostly good experience with Eligius on S1, apart from sometimes delayed payouts. |

i found they want to failover to the 3rd pool at times - after removing the 3rd pool i have considerably less ppc income...
this is strange, I have not seen this. In fact, my second pool earned just 0.00009 BTC in several months on multiple miners, which also means that third would have earned essentially nothing. |

A stupid question:
I don't see any logout tab on antminer S2 gui as there is one on S1.
So, how do you logout from S2?

This is a different controller mechanism. Take a good luck inside the slot and see if you can see any debris or loose pins. Its unlikely but worth a shot.
Thanks, no, no debris or visibly misaligned or loose pins. I even tried to vacuum with a small handheld-nothing. I am wondering whether to continue at 90% or send back the miner and lose a week (if all goes well). Phillip on the main S2 board suggested that it might not draw enough power somehow on slot 1. is this possible? I can check it, but as always, tough to do this when hashing is going on. |

I've got an S2 with only 9 slots working. I know that it is the slot and not the board because i switched the boards around to no positive effect.
Anybody had the same?
Is this somehow fixable or a lost cause and I will have to endure a 90% miner. I will ask bitmain for some compensation. Was anything ever given in cases like this?
Where is LOGOUT on the web gui? I don't see it. It is too minimized in comparison with S1, in my opinion.
try putting one of your pools on line 3.. you only have two pools. copy line one and have it on 1 and 3. did you always try to run all 10 cards or did you try slot 1 and slot 2 only? just run 2 cards to see if slot 1 works. your psu may be only able to run 9 cards and slot one is the one that gets the least power. Thanks. interesting..., no, did not try to run just two cards-will try. re pools, i usually don't bother with a third pool. it never affected anything in a good way, but I certainly got some trouble when I specified btcguild as third at one point. |

Anybody can help with what I see on my S2 unit? To me it looks like one slot is dead, which is very strange. I tried to switch boards and it did not help, eliminating the board problem. What else could it be but the slot problem? In additon-a silly question. Where did LOGOUT go on the web gui? I also tried to reboot miner from the web gui and it did not work properly either, the machine got stuck, had to manually restart. I wonder why what work so nicely in S1 is not working as well as it did before (rhetorical question).  |

A question: out of 3 tar files on bitmain site, do you need only the last (from 20140410) to put on backup SD or all three of them. Instructions are unclear to me.
Do I just put the tar file directly there or decompress it first?
What is the use of SD partition tool? Much obliged for any help.

Hey, does anyone know how to tell which electrical outlets are on the same circuit? Is there some kind of tool out there you can buy that you can plug in one outlet then go around to each other outlet and when it sees that other plug it will light up or something? When my house was built the electricians did a SHIT job, but since I switched from central AC to window AC I have some power to play with but want to make sure what outlets are on what breaker. I know they messed up because a couple outlets in my living room go out at the same time ones go out in my office. And that's two room away. Unless that's the way it is done? I was NEVER any good at electricity. Horrible at it.
http://www.homedepot.com/p/Klein-Tools-Receptacle-Tester-RT100/203195018This will test 120v circuits for 5 bucks... +1 Exactly how I do it!! Turn a breaker off & just walk around the house & find the outlets that don't light up,label the outlets with a little marker the same # as the breaker....DONE!!!  Yep...running around with a single bulb lamp and labelling stuff. The funny thing is it is usually not me who is walking around the house with a ruler and "planning" things, |

the only restriction is I have to stay under 800 watts. I have to make them run quietly. they do run pretty quiet . I think I will order 2 more s-1's today or tomorrow
One of my S1s came with a broken fan, I replaced it with a push/pull pair of Corsair AF120 performance edition fans (30db) and I must say that that miner runs at the best hash rate 205.6 and the lowest temp - by 3-4 degress, and is by far the quietest - over the others. £25 for the pair. Bitmain promised to ship a replacement fan with my next order. thanks. If I see them on sale here I will grab some. I have found that on my over clocking the gear has been pretty loud. but on my under clocking I have a corsair vortex and I have the stock fan. the stock fan runs under 1500 rpm and it is quiet . but testing new fans is cool with me. I dont really get the underclocking stuff if I'm honest Phil, I need to max the income from these things before they become useless... Happy to be enlightened however... Undeclocking, or undervolting is actually very interesting and is probably a must in places where energy is at $0.3/kwh and above. Plus, units might last longer. i think the strategy might be to run at stock speed or overclocked to whatever level your ants are comfortable with (one of my units cannot go above 350mhz, one 375 and three 393). After that-either continue as before or reduce speed and enjoy profits for longer, perhaps. |

I forgot to mention, but I got my BTC refund for 3 Neptunes on the 20th May, just hours before the price started to rise. KNC couldn't have chosen a better time. Original purchase price for 3 was around 30400USD and I got 66.5BTC back at 457USD exchange rate. With the current exchange rate that is almost $8000 ahead. I am so glad I requested a refund  I am glad that you finally got it. Perhaps, your thread was attacting attention... I got mine at $445, but had to sell some. |

So does anyone have some information to share about underclocking?
I had a scary moment today when my main circuit breaker tripped. I'm running a large number of miners including 3 S1's. I underclocked everything I could to prevent it from happening again.
I changed my S1's from 375 to 325. I dropped from 190GHs to 166GHs which is fine by me. This isn't about the extra pennies I'm losing by not overclocking. This is about power efficiency and waste heat generation.
Does anyone have stats comparing watt usage for 375 to 325? Is there even more significant efficiency to gain by going lower?
I run mine underclocked (for efficiency due to electricity costs). I get 150GH/S per ~200w @ 300, rather than 180GH/S for 380w. I essentially went through the same process described in the link pvnamk19 posted above. So you had to do the pencil mod to get to 200w? I'm not really interested in going to those lengths to undervolt. I'm only wanting to underclock. Sorry, I didn't read the entire thread so maybe my scenario was addressed there. no pencil mod means 2 watts per hash. so a 350 clock gets about 180 gh and around 360 watts with a plat psu a 300 clock gets about 150 gh and around 300 watts a 275 clock gets about 140 gh and around 280 watts but read below: please get a fucking pencil lightly stroke each of the 8 resistors 2 times do not measure the ohms takes 2 minutes. set the clock at 300 and see what the results are. about 150 gh and 200 watts is pretty much what happened for me, it is easy to do this. below one at stock volts and 393 freq gets me 200gh and 406 watts and one at undervolts 275 freq gets me 140gh and 201 watts I am thinking about undervolting, got myself the HB pencil, but the resistor that you supposed to touch is so tiny and there is another object nearby (C10). How you were even able to do it reliably? magnifying glass workstation? i think that you supposed to use the multimeter (ohm meter) as well. I have 3 running on an evga 1300 supernova psu about 420 gh pulling 563 watts at the k-a-watt plug that is 1.34 watts a hash. I can't tell you how easy it is. I have had cataract eye surgery in each eye and I can do it in 5 minutes I used a number 6 pencil on one mod and a number 2 pencil on the second mod. I deliberatively was sloppy on getting perfect ohm measurements after the mods. I have an hi-end meter all resistors read 4.46 or 4.47 k ohm before the mods. I allowed the resistors to range between 2.4 k ohm and 3.3 k ohm after the mod . The key is your ssh. you may want : 250 freq 275 freq 300 freq if you fucked the resistors up a lot you get x's on your asic's just go to a lower freq. I stroked the resistors in 1 direction away from the one next to it and towards the empty space. I used a magnify glass on a stand http://www.amazon.com/Carson-DeskBrite-Illuminated-Magnifier-LM-20/dp/B003EW1ZNC/ref=sr_1_4?ie=UTF8&qid=1401213622&sr=8-4&keywords=magnifying+glass+standthe photo below is with the glass. Thank you very much for the instruction and link. I'll give it a shot-it's getting close to "real" summer season here and i want to reduce power use. I am getting addicted to S1 ants . Basically holding myself not to order a couple more. |

has anyone attempted upgrading to a new 1300 Watt PSU?
I put EVGA1300's in mine and get 1148 @ 225 Freq. HW Errors are super high, but it does increase W/U by 2000 or so. I've got EVGA 1300 coming, might try it in S2 instead of 3 ants as I planned. So, what % are HW errors? Sorry, what is W/U? measure of work done? |

cashouts that big (40k$) can make some problems, im curious however in cashouts in milions, early adopters could tell quite a story i suppose
Yeah, what happens if you send a cool million to an account that never has had a balance over 10k  I think they'll freak out. first, send 20K, then 50 K, then 100K, then the rest 830K, LOL. On a more serious note, in US FDIC insurance is up to $250k, so everything above it you can easily partially lose in an unlikely bad situation. You would probably need to have a different type of account with the bank (Edit:brokerage), where you immediately convert money above 250K into treasury bills. |
