As promised, quicker way to fix config page issue 1)Putty into S3 2)Paste the code in below.. Will replace Save&Apply with Save&Apply. sed -i 's/Save\&Apply/Save\&Apply/g' /usr/lib/lua/luci/model/cbi/cgminer/cgminer.lua Thanks for this. Just updated one of my Batch 1 S3s, applied the line above and everything works great! One question, what values would/should/could be entered in that new 'Voltage' field for the S3? And what effect would these values have on the operation? |

I hate to ask this, but I can't find the answer anywhere. These coupons, I have 20, can I only use 1 per new miner purchased or can I apply multiples to a single miner purchase? Also, are they restricted to which miner I can apply them to?
You can use 1 per miner purchase and the type they can be applied to is written in the title/name of the coupon. If you wish to sell them please use the correct marketplace forum. Thanks! Feel kinda stupid, I didn't even notice they said S3+ in the title. DOH!! |

I almost at breaking even point on ROI on 4 antminer s3! Bitmain u rock!
It's all gravy from September 2014 and onwards! This was the best purchase of mining hardware that I ever done! The last line contradicts itself by my opinion and helps me to prove my point that after ROI the S3s will be useless. all this complaining about will it pay off seems to completely totally ignore you most likely already have equipment presently mining that paid itself off months ago... so spending a lil more to boost what is already mining pays that off in a month or less. depending how much mining power you already have. it seems like a huge oversight in the whole whine. never mind as the complainers whine and whine, the words (SOLD OUT) keep coming and going... kind of like crying in the corner while everyone just moves along with the flow Thank You!! I've tried to make this point but nobody seems to want to hear it. |

The ROI with bitcoin purchases can depend on how you look at it. I purchased some S1s with bitcoins that I purchased at about $350. To keep the math simple, say the bitcoin value was $650 when I purchased an S1 at 1 BTC. Did the S1 cost me $350 or $650?
I feel that it only cost me $350 since that's what I paid for the 1 BTC.
For tax purposes, I'm using FIFO accounting similar to when opening and closing a stock "tax lot". But for tax purposes I'm not sure whether I should be taking a capital gain of $300 for when "I sold" the bitcoin and then claiming the S1 cost me $650.
Guess it depends on how the IRS treats. Will be fun at tax time.
interesting...I say that if you purchased 1 BTC for $350, then bought something that cost $650 with that bitcoin, then yes, you had capital gains of $300, but if you bought miner for BTC, then you just spend your original $350, UNLESS you later sold your miner. Selling would close the "circle" of transactions back to cash. What about if you bought with BTC that you mined using other equipment? In the simplistic view, that BTC cost you $0. |

Moving away from the negative hopefully.... I have an ROI question that I cannot figure out how to calculate. As I have stated, I am able to set up miners, but not really smart about them.
I own 4.8Ths that is already ROI, including electrical costs. I have pre-ordered two S3+ to (hopefully) ship around Sept 20. They were paid for with 1.16BTC generated by my mini-farm after it reached ROI (free BTC). I calculate them as 450GHs each or 900GHs for the equation.
That will bring my mini-farm up to 5.7THs. It has been established and is almost not arguable that a single S3+ cannot ROI by itself.
My question: As an added component to an existing farm, is it possible for the additional benefit of two S3+'s to the already income-producing condition to 'ever' benefit by 1.16BTC? I don't understand how to calculate existing hashing power into the ROI equation.
Thank you for any assistance. I also would like to apologize to JPChrist. I agree that personal attacks do not benefit the community and I look forward to learning from his helpful posts.

since your 4.8 TH farm has given back the investment, what they do now, is give you "free coins" (if they generate more, than what your electricity costs) so, for everything you add to your farm, the only worries you have, is to deduct power costs and and then you can use the rest to make your ROI on your S3s go away faster, but remember to "save up in the bank" to be able to buy newer equipment, when your old equipment cant pay for the electricity alone anymore.. I started out with 3x Antminer S1s they have ROI and given me enough coins to buy the 2xS3s, now i have all 5 units hashing away, and i almost have enough to buy 3x upgrades for the old S1s... FINALLY!! Some sanity to this ROI stuff. I started out with USB Block Erupters, then to blades, the to S1s and now S3s. Each upgrade was paid for with BTC generated by the previous hardware (both from mining and reselling) The only "investment" I made was in the original bunch of Block Erupters and supporting equipment. That has long ago been paid back (I actually cashed out enough BTC to repay my initial cash outlay) Now my small farm of 10 S3s pay for their monthly electricity usage in 1 week of mining. Another thought on ROI...No company does ROI on every single piece of equipment they buy. It the money generated by ALL the equipment they are using to create their product against cost of ALL of the equipment minus salvage value or whatever is left on the depreciation. |

I have a question about the stratum difficulty. I have two Antminer S3s, and I'm using the GHash.IO mining pool. Their FAQ says: The optimal settings of the stratum difficulty depends on your hash-rate:
16+ GH/s - 16 difficulty
32+ Gh/s - 32 difficulty
64+ GH/s - 64 difficulty
128+ GH/s - 128 difficulty
256+ GH/s - 256 difficulty
512+ GH/s - 512 difficulty
1 TH/s - 1024 difficulty So based on that, the setting would be 256 for each miner. Does anyone actually alter this setting in their mining pool? Or do you just keep the default setting? thank you. I don't think it's for each miner ( unless you have them as different workers). If they're set as one worker, then set it to 512 (or 1TH if you can get it stable over 1000 GH/s). If they're separate workers then yea, 256 should be fine. But Yes it works in every pool I've tried (4 or 5 different pools) They are set up with different worker IDs. I thought that was required. I didn't know I could have two miners in the same pool with the same worker ID. Does that work? Is there an advantage to doing that? No... It's hard to see/track your individual S3's performance... I'm using separate workers for each of mine S3's ...256 diff...  ZiG But Yes it works in every pool I've tried (4 or 5 different pools) |

So I got my antminer s3 running..
Its doing about 500GH/s which isn't bad..
Do you all mine with ghash.io or?
I use BTCGuild, Slush Pool, and Eligius. Over the course of a few weeks that all payout about the same. With BTCGuild you get a pretty steady trickle. With Slush you get a fairly steady stream, but them seem to come in batches. I get Eligius payouts every couple of days. It's a much larger amount than the other pools pay per payout, but in the end they will pay out about equally. |

wouldnt running 340 watts at the wall constantly 24/7 cost about $5 aday to run, which is what these are making at today difficulty so why bother?
WOW! cost less than $0.50 a day here That's like $0.60 per Kwh! Can't be right. I'm in the UK and we're on a "cheap" tariff £0.12/$0.20 per Kwh (£0.97/$1.63) and I make about £4.60/$7.70 per day in total at the current BTC value. But I do it because its an extension of my computing/electronics hobbies  My kWh I think is around 0.092 last I checked. My Kwh is 0.1050533 and that includes both generation and transmission. I just take the entire electric bill and divide it by the Kwh used. So it costs me about 86 center per day for each S3. With 10 S3s running I make enough in 1 week to pay for the entire month of electricity used. |

Just got done flashing all four to the new firmware, hope all holds up well. If not, I go my backup I made.
Which BTW, can backups be used as rollbacks ?
Ex. Say new FW hates me, can I use backup to go back or do I need to get a new DL from the Bitmain site ?
The backups only backup the /etc/config directory, not the firmware. |

Has anyone tried to use avahi (bonjour or Zeroconf) on either the S1 or the S3 miners? This would be very convenient as it would allow using dhcp and never have to worry about the ip address. You could just address the miner by <name>.local . Since this is basically OpenWRT, there is an avahi-daemon package available. I installed it on an S3 and it worked for a couple of minutes but then it stops resolving the .local name. I saw nothing in the logs to indicate a failure. When I restart the avahi-daemon service it's all good again for several minutes. Played with config files, nothing worked. Ideas?
BTW, this has zero effect on the hashing.

Is there any advantage, other than tracking, to make multiple workers at a pool? Such as 1 per S3 or 1 per S1. Or is it just as well to have all your miners using the same worker?
I don't think that different miners can use the same worker (in the same pool), although I am not 100% about it. You can use the same wallet in Eligius, just add _<shortname> like this: nbmxjwgiwgwigiwgwigwcb_bob1S3, _bob2S3, etc, etc I group my miners by type into workers so I have lots of miners using the same worker. (all S3s to one worker, All S1s to another, etc) This works on BTCGuild, bitcoin.cz, triplemining and Eligius. Was just wondering if I was giving up or gaining anything by doing it this way vs the 1 to 1 miners to workers. |

I fired up a new S3 and it has a newer firmware date of "Mon Jul 28 13:12:00 CST 2014"
My 6 Batch 5s all have that same firmware. DOn't know why they don't put it on their website. I'd like to flash it to by Batch 1s. Can't you just backup the firmware from the B5 and restore it on a B1. I'm Curious to see if it would help them, like many i have a unit that won't break the long term avg over ~400Gh no matter what i tried, i even took the think all apart and replace the termal paste on the back and front of the boards. Put heat sink on the dc-dc chip and also on the R7 Chips. still didn't help. Let us know. The backup from the GUI only backs up the /etc/config directory and not the firmware. Anybody know a way to backup the firmware into a .bin file? |

None of my 6 miners show a performance of 441 Gh/s at the pool (438.44, 422.08, 413.11, 411.2, 389, 382.51). The working temperature of the webgui shows about 40 degrees, does anybody can offer some help how I can increase the performance (read something about restarting cgminer)?
Depending on your PSU, (recommend 600W at least for a single miner) and all 4 PCIe power plugs used, you can overclock it a little bit. Search this thread with Overclock and you will the instructions to do that...but just the same SSH into your miner and edit the /etc/config/asic-freq file. If you are comfortable with a linux command line this should be easy. Otherwise follow the instructions in the post after searching  ç dogie says with 1 CX750M you can run 2 S3 I am running 2 S3s with stock clocks on a CX750M with no problems. |

Sorry for a question thats probably been asked tons
I have just preordered in most recent batch
For 1 S3, Would a CX500M Corsair PSU work
For 2 S3, Would a CX750M Corsair PSU work or should i stick to a single PSU per miner
I have single S3s running on both CX500M and CX600M. I also have 2 S3s running on a single CX750M with no problems. All are running stock clocks. |

Every half hr, lol, thats waaaay too often.
Once a day or every 12 hrs should suffice.
is 12,00 * * * * /etc/init.d/cgminer restartthe command for restarting every 12 hours, then? could someone comment if this is OK to put this in <System> tasks instead of ssh-ing? Yes, System-->Scheduled Tasks works well. |
