I also noticed the load average is way lower on the CPU now that it was. was always above 2 before. now hovers around 1.2. any additional benefit to these devices to run with lower/higher loads?
That's likely the advantage of the newer version. In principle it will lead to less lag time in keeping the device busy and less time to process and send shares. However cgminer is so heavily multithreaded that it probably won't matter since the latency critical parts of the cgminer code are already prioritised. Pushed 4.6 to (60) S3's, they're all working great.. (60 minutes runtime). Thank you sir, much appreciated! |

It really sucks that there are so many scammers out there. I can't even understand the mentality that makes people think stealing is a cool thing to do.
I agree. I hope that purse.io takes steps not only to protect against this type of abuse in the future, but getting BTC back for people scammed this way. |

I'm a long-time purse.io user, love them, have had only good interactions on their site, till now. I notified purse.io, hoping they'd at least investigate, find the user, remove any coin from their account, let me know they'd banned them, etc.. But their response? Sounds like a great big bag of "not our problem"... Because amazon both sold and issued gift codes, they have full control over it. We recommend buying non gift card items.

I will continue to use purse.io (just used them again this morning, in fact) but this is a problem that users need to be aware of, and that purse.io needs to find a way to address. Until they do, they should ban all gift cards, they're too easy to exploit.

So I have (1) S3 that will let out a single beep every couple minutes, but the rest don't. Is there some stat in cgminer I should be looking for? Queue depth perhaps?
Of how many? What firmware? Are you using a pool that it is loosing a connection to with the original firmware?. I know my beeped alot until i turned the beeper off. ;-) it seemed each time the multi-pool i was using changed work load it would take the miner a minute to get going and beep. original shipping firmware, and 1 out of 30 beeps. not sure which one however..  |

Will Bitmain continue their dominance of awesome early delivery of on spec machines with a new S4?
My Bet is the S4. 2TH, 1400W. |

... i performed a factory reset and have used an ip sniffer...so the controller card seems to have taken a bad flash..
That's what I'm in the middle of right now.. Did you ever find the "boot" IP address it uses? I'm hoping there's a tftp-push recovery mode I can use to try to get the device back up, like every *wrt router I've ever owned. If you made this work, do tell! |

I am curious has anyone had any RMA issues with Bitmain ? i have provided them with the order ID and I am still having the hardest time getting RMA information from them. They have demanded I perform a test with something called a multimeter (which i do not own, i had to go purchase one) so i could test the chains. My s3 device pretty much bricked itself with a firmware upgrade. I cannot access the UI, the ip is not found (never changed from default). I used an ipsniffer, and still zilch....anyhow, i am curious to know how Bitmain has dealt with RMA requests from others. Thanks
It took me 2 1/2 weeks of those emails back and fourth. I finally told them I would sell it for parts on Bitcointalk.org and tell everyone about them not honoring warranty. Then and only then did they sent a RMA form. I sent it(controller) off 3 weeks ago and still don't have a replacement. Good luck. What were your failure symptoms? I had one die today.. going to have to go down this road... |

Think I had my first S3 die, want to confirm. Got idle miner notification, was able to connect to box, cgminer would start when crash - restarted box - no change
- power-cycled box - no change
- noticed the web interface kept throwing "file not found" errors
- thought maybe file system corruption, replaced cgminer binary from good miner -- no change
- figured i'd try a code upgrade -- no change
- swapped PSU -- no change
when I start cgminer from the CLI, it will run for a while, but at about 100-110GH.. none of the ASIC show disabled. decided to power cycle it again, and now it won't come back up.. it's on, but the RED LED just flashes ON..wait.. OFF.. wait.. ON... wait.. forever. is it dead? Suggestions for recovery? Took a quick video, two booted at the same time.. at around 32 seconds you can see the right one take off, left one never does. https://vid.me/Hq1 |

Thanks for a great guide, very helpful! Since pypy is so much faster, it would be great to see steps to get pypy happy added, if possible.
I finally got it working, had to do the following, as the user I wanted to run p2pool as: #sudo apt-get install python-setuptools #easy_install --user -U twisted #easy_install --user -U zope.interface Now you can start it with "pypy ./run_p2pool.py" instead.. and benefit from the speed increases. |

Any quick fix for getting pypy happy with twisted on Ubuntu 14 LTS? python-twisted is installed, python runs p2pool just fine, but trying to run it with pypy errors: bitcoind@p2pool:~/p2pool$ pypy run_p2pool.py
Traceback (most recent call last):
File "app_main.py", line 72, in run_toplevel
File "/home/bitcoind/p2pool/run_p2pool.py", line 3, in <module>
from p2pool import main
File "/home/bitcoind/p2pool/p2pool/main.py", line 17, in <module>
from twisted.internet import defer, reactor, protocol, tcp
ImportError: No module named twisted

Honestly I'd like to see an 8pin EPS12v to 6pin PCIe adapter. I caniballized an EPS12v extender to attach leads from my R-Boxes but most of the hardware I'm ordering these days uses PCIe connectors, and most of these power supplies have 8pin 12v connector that I can't easily use.
I'm not sure how many others would be in the market for such, but I'd sure like to see it. Count me in for an order of at least two if you make them.
I'm interested in 8-pin to 8-pin. Like you'd run from the modular PSU and then to those splitters... about as heavy of gauge as you can fit in 8-pin, and 3ft length. |

Any chance of Bitmain S1/S2/S3 support?
|
|
|
|
Looks amazing, however, as mentioned on the thread, no client for embedded miners like Antiminer, KNC, etc... yet.. |
|
|

As someone mentioned on the reddit thread, you should consider having pre-compiled versions for some of the embedded miners, like KNC, Antminer, etc.
Sure I would that, however the problem is, that I don't own any of those devices. So far I only know that Avalon is running on OpenWrt, but it's hard drive and RAM it's rather too small to run Mono framework. I would have to somehow write another client... The way I see it for now is to have another machine, which would connect to those miners and it would monitor it from this another machine. This of course isn't perfect solution... reboot/restart worker commands won't work and we need another computer to run the client. Maybe you have any thoughts on this? Most of us mining more than 1 box have some sort of 'babysitter' box sitting near by, that could connect to the cgminer API, pull data, then publish it. I think that's a great idea. |

ok, I went back 15 pages, but didn't see this answered, so I hope I'm safe in asking:
Antminer S3 support yet? I see S1 & S2 folders, but no S3 folder yet.. Hoping Kano has a binary soon..
Trying to compile my own, but getting the build env right is... painful.
Not yet sorry. I believe he is/will be working on it. Thank you! Can I assume the that device support is already present and mainline'd, and we're just waiting for a usable binary? (IE should I keep trying to compile my own?) |

Here is a comparison on projected returns with network difficulty increasing 10% vs 20% after power costs assuming BTC US value remains at $600 per BTC.
Awesome chart, thank you for sharing. More colors than my sheet, but same conclusions. |

Probably a really dumb question here but................
Say a person just ordered 30 S3's and wanted to find a more economical (not in terms of price but in terms of setup )solution to powering them all instead of buy a ton of standard PSU's.
Does anyone know of a solution involving a larger power supply unit that could say, power 5 units off it instead of having to have a dozen standard ATX psu's?
If you're looking for something easy, most of the >1300W power supplies will power a minimum of (3) S3's.. That would mean 10 PSU's for 30 machines.. easier to manage. If you're looking for something cheaper, you can buy 100-200A 12V supplies in varies forms (server PSU, LED power supply, etc) and cable your own solution. |
