A random observation:
1. It seems that upon loss of internet connection, S5 sometimes latches on a funky state: fan is not spinning or spinning minimally, but temperature is rising.
2. We had intermittant comcast problems in the last few days, so i observed it on a few occasions.
3. I felt that air coming out was very hot, and upon restarting the miner by PSU, miner reported 0 hashing, but temperatures of above 80 degrees at the sensor, so i had to switch it off for 10-20 min, then it worked as it should.
I believe that someone described something similar before.
The solution should be in software, which should maintain fan speed at a certain (closer to high) speed until internet connection is reestablished.
The fact is that the S5 miner does not fully switch itself off on internet drop or, at least, does not maintain fan speed long enough to coool the machine after internet dropoff.
I mentioned this exact same thing happened to me before. Maybe 3 weeks ago or so in this thread. Even a couple others mentioned the same thing and had screen shots showing over 80 degrees, which shouldn't even happen if the shutdown is 80. All my rigs stopped because of a sporadic internet connection. Miners fans stopped and they all turned into little heaters, getting hotter and hotter. All I needed to do was put my hand or face near one of them and felt the heat spewing off. Thank god I was home to power them off or all my rigs would have over heated. I mentioned and tried to bring this up but nothing came about because I had no "proof" it seems. This happened to me twice on all 6 of my S5's and both times I was lucky enough to be home and power off. I've also seen this. Last weekend while doing network changes I was off the internet for about an hour. 10 minutes in all of my s5s started either maxing fans or the fans shut down, but the heat kept going up. |

Sorry about the delay for all the planned features for the app. I've been swamped with other responsibilities. I got to false block found responses tonight. Not sure what that would be about. |

Running 10 S5 on f2pool now and no reboot needed so far. The others on nicehash keep crashing, seems really pool related.
Nicehash was working great for all S3 for months, never had an issue. Only the S5 have problems.
I'm running 6 S5s on kano main and extranonce with p=0125 on westhash and I've only had one issue in the last month, all 6 s5s were about 100g/h less than they usually were after a series of rapid switches over a day, I rebooted them and moved my p= amount up a bit to stop switching. I'm running smit's firmware with cgminer 4.9.0 |

It not the not found block issue it is the miner disconnects from the pool in the past few days there have been large drops where the moners slowed to 25% of there capabilities, I have seen this several times then they drop completely, I suspect a pool issue and they come back to normal and then i see there was a server reset.
I am very happy with CK pool and am grateful for all your support here. So no I am not complaining at all.
Just wanted to make sure you know whats going on and to see if there is a issue that might need to be addressed.
There's a lot of us that use nicehash when their price is high, and it has been for days now. Once it goes back to normal my 18T/h will be back here and so will a lot of others, but for now earning 30% over normal is worth. |

I see the S4 + is out not a bad price wondering if well see a ANTMINER S5+ with improved cooling and maybe at 1.8 or 2 th maybe ,,, hoping hoping. at about the Same S5 price   ? . Idc what power it uses at this point i have to start using a 240 line to many miners on my 110 lines time to start using the 240 line , i had put in .  . The price on the s4+ is pretty awful. |

Router and everything is definetly not the problem.
IP adresses work 100% and other miners than S5 have no issues at all.
Nicehash might be an option, i will switch 10 to another pool and see if it changes.
Any idea why nicehash crashes them?
Nope but when I moved mine to f2pool they were up for weeks instead of rebooting them daily. Isn't this because of the lack of "extranonce" support? (dunno, just throwing the idea up there) I have been on Nicehash for 24 hours and have had to reboot twice. I think the low difficulty of mining shitcoins sends an AntMiner into a circle jerk on the Interwebs. Am I right here? I'm using Smit's firmware on 6 S5+ boxes and haven't had to reboot once, and they are averaging 1.13TH/sec over the last 3 days mining on westhash. |

Strange, my s5 working with nicehash for weeks and no problem at all.
About control board: try reflashing firmware without save settings. Sometimes that helps get rid of problems
I've heard this before but all I can say is that for me Nicehash doesn't work even with new firmware. That's because nicehash sucks you could not pay me to mine on that site !!!! What are you talking about? Nicehash's average payout over the last month is 102% after fees and you get paid for all shares you submit every 6 hours. Currently my 18TH/sec is earning around 130% of expected norm and has been for a couple of days now. I can't see why you wouldn't mine on Nicehash full time to be honest. |

could some of you guys put the price and roi estimated of this relation ships of this ant miner s4 and s5 it seems it takes like 8 months to roi and the watts my god sorry my mining skills are not that big
you will never ROI the S4+ or S5 unless you have other miners to help. unless you have completely free energy.. then it will take like 215+ days. at this point it is best to buy BTC and hold it. Because maths: At free electricity, flat difficulty, a price of 230/coin, 100% average pool efficiency and no pool fees: It takes 118 days to ROI an S5 (ETA .369BTC/month @1150GH/sec) It takes 153 days to ROI and S4+ (ETA. .82BTC/month @2570GH/sec) At .10 USD per kw/h, flat difficulty, a price of 230/coin, 100% average pool efficiency and no pool fees: S5: Cost to run: $43.00, earning $85.00 = ~$42/month in earnings, taking roughly 9 months to break even. S4+: Cost to run: $108.00 earning $188 = ~$80/month in earnings, taking roughly 12 months to break even. The only real value the S4+ has over the S5 is that you don't need to spend money on a PSU/cables, but I feel the price that Bitmain is asking is way outside of reasonable for that hardware. |

Is there an estimate on when the new models will be available for sale?
Any leaks or guesses on performance and efficiency?
If they're relying on 16nm finfet we won't see anything until Q1 of 2016. |

From the S4+ description: " 2. The PSU is designed by Bitmain. The headache around the S4 PSU will not happen again. "  $1000 for 2.5th/sec? Not really awesome. |

I was going to buy a couple more S5's but the price is still $340, so I just bought bitcoin instead. I even asked Bitmaintech to see if they would lower the price considering it's been there for quite some time and they are shipping used hardware anyway. Nothing received in stone. Only reason I wanted to grab 1 or 2 more is because I have a free electrical outlet. You guys still aren't buying them at that price point, are you? I doubt the last sale they had no one will ROI anyway unless free electric and free power supplies all the way.
Buying BTC at current USD value makes way more sense than buying an S5 at it's current price. I've been purchasing BTC via coinbase for the last few weeks myself. It's going to cost me way more than $340 to mine 1 BTC with an S5 rather than spending ~$223 USD to acquire the same BTC presently. I'm honestly surprised Bitmain has remained firm with their pricing at $340 for so long (when you're the only game in town, amiright ?) which is even more incentive to buy BTC than their miners right now. It all depends on your electical costs, but for long term holding the current purchase price looks more attractive than miners unless you have REALLY low kw/h costs. |

Thanks for a cogent, clear, and calm response to my inquiry. When I started back in 2013, I was mostly concerned about pool manager fraud, and it seemed like Slush was a good choice using that metric. As I have gotten more educated, and more invested, it seems I should pay attention to some other options for a pool.
Thanks again, Kano!
I strongly recommend kano.is to mine on, he's active, super helpful and constantly working on development of ckpool. |

I've just in the last 3 days rigged my SP20 to use Westhash as my primary pool, and Slush as my backup pool. Prior to this, I have mined only on Slush. I currently have my password on Westhash set with p=.0104. My SP20 has spent a great deal of time on Westhash, with some short breaks back to Slush.
My general sense is that I am doing less well on Westhash. Yes, I know it's only 48 hours of experience, and Slush might be on a lucky streak. Nevertheless, I am wondering if my p= value is too low, or if I am just not understanding what to expect. My simplistic vies is that I would set p= based on the expected BTC I would earn in a day with 1TH. Based on bitcoinwisdom, that looks to be about .01017 (round up to .0102). I then chose a value such that it would only switch if it was "real deal" on Westhash.
I would appreciate any comments and insight that folks have to share.
I don't think pool hopping benefits you on Slush with how they deal with discards. A ppnls pool will work better if you're swapping back and forth. |

Trying 7TH here. Signed up with an account, now what? Where would I see my workers? Their stats? Anything on my hashing here? NOT mining with a BTC address. Using an account. Seeing information is key.
EDIT: Is Kano related to Westhash? Seems this is the only pool where users use Kano and Westhash at the same time to go back and forth? Kano isn't paying enough, so they have to dump over to Westhash? Kinda of rude, no?
Well, hopefully someone can tell me where I can see my stats or workers or anything...or I'll just move on to another pool. Have another 10TH mining somewhere else now, waiting for a new home maybe.
You come off as kind of an ass. Sign up, log in, you can see all of the stats you need. Overall this pool since its inception has paid about 4% over expected. |

Bringing 2 more S5s online tomorrow.
If I can finish this deal with a building owner in Washington state I'm hoping to bring at least another 30 - 40th online, then maybe rent space to miners as well.
