Agreed, this maths "wizard" is talking total rubbish. I made a pittance here and since heading over to Slush have made loads more. Currently I make 0.001125BTC per day with one S9. I'm not going to bore anyone with math (because to be frank, who gives a darn about it, we are here to make coin not learn algebra), I'll just post a good old fashioned screenshot of earnings on Kano with one S9. https://ibb.co/ckaXQxYes, we are having a shocking month but still, with difficulty ramping up all the time, every day is precious to new miners starting out who can't afford runs of 200-600% blocks. I keep seeing all this about pool x, pool y, pool z vs here or maybe I should just say PPS vs here.
So after 35 days I figured it was time for a few real numbers.
I started here on the 18 (night) of January, with what was 15Th as the time, but that quickly doubled to 30 a day or 2 later and has been pretty flat since (just added 22 more, but I'll ignore that at the moment)
The other day when I brought up my 821's, I put them on slush for 2 hrs, just because I wanted to see what the daily CDT was there at my full hashrate. Then I moved them back to here.
So here is the basis to my numbers.
30Th/s for 35 days
Actual numbers from Kano based upon the above.
Let's start with my Kano experience.
I received .0976473 BTC in 35 days
this equals .0027899 per day
or .0000930 CDT
for the same amount of hash at slush, we'll work backwards
.00008703 CDT
.0026109 per day
or .0913815 BTC
You can say what you want and this is just a snapshot of 35 days, but even with the really ugly luck we've had, I've still made more here than the equivalent time at slush (who btw is averaging slightly *better* than 100% luck).
The upside that isn't in the above, if we find a block today, my numbers would go up again to a much larger amount of BTC than slush (e.g. .0045 (would be .007, but I'll factor out the .0027899 CDT) BTC to .002), if we improve on luck, we shatter the slush numbers. If I left today and went somewhere else, I'd still be paid for 5Nd ramp down along with where-ever else I go's take.
I just can't see any downside. Ok, except the fact that you don't have a little graphical ticker that is counting up based upon predicted BTC.... Oh but wait, it simply matches the number above, so what real benefit is it?
EDIT1: with 30Th/s this should work for anyone curious with a 14-15Th/s S9 or anything else because I took all the numbers down to CDT (Coin per Day per TeraHash/s)
When you say you started the 18th of january were ramped up by then or is that when you started ramping up? I started ramping up the same day with 56 TH and since then ive been payed 0.04798770 BTC.  Ive done the math and If i was fully ramped up for all four of those blocks i would have made 0.0739933168550874 BTC with 56 TH. Your math doesnt add up at all buddy. If you say those are actual numbers then post a picture to prove it. Also if they were actual numbers I would be pissed because someone with 35 TH made more than me with 56 TH. If you think you would of mined more at kano for that time period you are delusioinal. FUNNY, I wanted to call bullshit on these numbers too, because I had an average of 60 TH ( was from 68, 80, 53, 52 TH for the last 4 blocks) and All I made was .07935601 So if you were to take my whatever average you want to use, say 60 ( worked out to 63.25) and all I got was the .07935601 30 TH should be about half of that is what I would think. Re calculate, your fat fingers pressed the wrong button. I think what you did was you calculated your per TH rate, multiplied it by your TH that you had and assumed that thats what you would of had if fully ramped up. BUT the pool rate went up significatly at the end of Jan and early Feb ( I cant recall exactly what timeframe) so your percentage of total shares would have gone dow, but you had no real way of calculating that due ot the lack of blocks found. |

I was watching BTC.com last block time posted, and then kano.is timer at the top of web page is about 18 seconds behind.. Just wondering what is up with the time difference? Or any other way to check that is not so crude like my method?
Just checked last block 509209 and its time stamp on kano server is 2018‑02‑14 19:53:00
Time stamp of the same block on BTC.com 2018-02-14 12:52:44
Kano is 16 seconds later than the BTC, ( disregard time zone differences for the hour)
Blockchain.ifo has the same 2018-02-14 19:52:44 for block 509209
Funny, I picked blocks at random that kano found, and they are all on average 15 - 20 dseconds behind on time stamp from blockchain info.
Wierd..

What I was referring to with Biffa is getting more miners here on this pool and getting more of the network hashrate. Not going out and adding to the hashrate. He (Biffa) is stating that we should go out and "add" to the hasrate and thus add to the increased difficulty. I would rather take from the current total network and transfer a larger percentage over to us. That is why I am asking after he (Kano) said he agreed with Biffa.
The reason why Biffa is correct is that if no one was increasing their hash rate, then the pool falls behind the "Diff Curve" Yes of course adding to the "Diff Curve" ourselves pushes the "Diff Curve" up, but in reality that isn't the case, since if we don't, then someone else will buy those miners and push the "Diff Curve" up. There's been no lack of available buyers for available new miners for a long time. i.e. you haven't been able to slow down the "Diff Curve", by abstaining from buying miners, for a long time. Indeed getting large miners to move over from somewhere else is the best solution, but once we have some over here, we can't say: 'OK that's it, we don't need to keep up with the "Diff Curve"' Well, hopefully, it will slow down here. There have been new S9s available from Bitmain for over a week now. We need to tackle this issue and stay on top of it. Glad to have you in charge and we all really appreciate your support here. I'd expect (without much doubt about being correct) that Bitmain mines with their miners before they send them out ... yes .. they call it "QA testing" ... lol not to mention all the "dust" they get. .. cos all their miners are configured to point to their pool by default out of the box. so when a newbie miner plugs it in .. while trying to figure out which pool to point to .. and setting up the accounts ... those couple of hours all add up ... Just do what I did, create own VLAN, do not give it internet access, then configure S9's then enable internet access. But i knew that it was "preconfigured" before I got them. They never got one hash out of me. |

The plan is to put it all on 240 volt, to balance out the load across L1 and L2 I just haven't had time to finish it all.
I am tempted to move it back to where it came from to see if the one power supply works. Interestignly enough, the plug I plugged it into has nothing else on it, and it is a plug right at the panel box, so it is significantly closer than the one in the garage.
Chances are it’s not your power as much as it’s the apw3++ psu. People have had problems with them running on 220v let alone 110v. The efficiency has a +/- range and I think it’s mostly minus. I would use 2 Hp server psu’s if I needed to run on 110v. Funny I took it back into the garage, and put it back where it was, and still one board didn't work, i moved the control cables so that the original chain 5 from controller was the far right ( chain 7 hash board) Chain 6 was to the far left ( Original chain 5), and Chain 7 was the middle board. Booted up with one PSU and worked. |

<snip>
They say a APW3++ is insufficient for a S9 on 110/120 volt.
<snip>
... it likes to be on chain 6 with a separate PSU. Will not work with one psu even if fist hash board is still on chain 6.
Any ideas?
Yes, the infamous "They" are correct. So why did it work until now, 2 months actually, and as well as 6 others one of which has been now 3 months. What changed that caused just this one to act different? |

Have a bad hash Board? Think Again....
I moved one S9 from a garage to in the house. Plugged it back in, hash board not hashing. Wow.. my luck.
So after several reboots, firmware downgrade resets, etc. I found one post that mentioned power issues....
They say a APW3++ is insufficient for a S9 on 110/120 volt. Well. I beg to differ, I have had them running for months like this.. several of them in fact.
Chain 5 was the bad one, I moved chain 5 from controller to middle hash board, found that now that hash board did not work, but the original one did.
Thought, well someone said it didn't have enough power, tried different PSU ( New one as a spare) Same issue. Hash boards all worked, just that CHain 5 from controller did not work. Bad controller?
Plugged in the other PSU to power one has board Middle hash board connected to chain 5 ( Swapped from chain 6) Powers up, boots, hashes on all 3 boards. Hmm weird.
Put back so that CHain 5 6 and 7 are in sequence again as original, still powering middle hash board with 2nd PSU, Boots, only two hash boards hashing ( Chian 5 is not)
Power up first hash board ( original Chain 5 connected to chain 5 ) and still onloy two hash boards hashing, BUT NOT THIS CHAIN 5.
Plugged in chain 5 from controller to middle hash board, powered this middle has board with second PSU, boots, hashes no problems.
So I cant figure out what is wrong. All the components work, but the first hash board does not like Chain 5, it likes to be on chain 6 with a separate PSU. Will not work with one psu even if fist hash board is still on chain 6.
Any ideas?
FYI, This posted for those who think they lost a hash board... Which I initially did, but was somewhat relieved to see that it still works. So you may want to trouble shoot more before you decide bad hash board.
To complicate things even more, just After i first saw this happen to this S9, I had two others experience the same thing, but 20 and 30 minutes after this one did. Both lost one hash board. But a factory reset on the one, and reboot on the other fixed those.
Confused.

That's better than at the steering wheel....  Mine on, when's the house-warming party?  Isn't your house warm already with all the S9's going? |

Has anyone tried to put one of them water cooled CPU radiators in from of the exhaust fan of an S9?
I am wondering if there air restriction is too much, and the reason is for heat recovery, to heat water to be circulated elsewhere and just to test if enough heat recovery is possible to make it worth doing.
Air temp coming out of the S9 is 45 Deg when ambient temp is 21 Deg C, so wondering if anyone has tried it, and if you know the temperature rise you got on the circulated water.
This could also be used for air intake, if you could chill water elsewhere and have it circulated to the CPU cooler radiator but on the intake side.
Crazy I know, but this is a more directed approach to cooling, since you only cool the air the miner takes in. Or you can use this same method for chilling to a bigger radiator for a bigger room.
Underground tank that holds water will be cooler than the outside air..
Or an indirect use of this set up with an evaporative cooling solution, so that no actual moist air from the evaporative cooler goes through the S9 and makes it corrode inside.
Just tossing ideas around.

How am I earning less on 27 TH's than on 16 or even 13? I assumed that payout is proportional?
The ´Miner Reward´, ´Pool N Avg´, and your ´N Avg´ are different for each payout. Although your hash rate has ramped up, the reward has dropped and the pool hash rate has increased resulting in a smaller payout. Thanks, I can see that they're lower, but that doesn't tell me why they're lower. How can they go down if my N Avg has doubled. Easy answer, share dilution. you increased your hash rate ( or still ramping up) and your reward is lower than before in part due to the smaller Block reward being only 12.44 instead of the other blocks @ 15-16. The biggest factor is the POOL average has gone from 32.68 to 46.8. Basically if you want the rewards to be the same, you have to increase your hashrate at the same rate as the pool rate ie whatever that percentage is. SO when large miners come with 9 or 10 PH, thats a tough one to keep up with. BUT after all he was the one that found that last block. In reality .00054759 is about 4.50 USD. using 8000 USD for 1 BTC I do understand over time that stuff adds up. We are all after those little numbers. On the upside, since the pool hasrate went up, the probability of finding more blocks goes up. So you should get more payouts than when the pool was at 28 PH. Only time will tell. |

What are the chances of us cracking over 30 blocks again without getting more hashing power here?  Just about the same as smelling a fart in a wind storm. |

so looks like your wire has a loose connection. you probably were wiggling it while you refreshed the page to see the fan speed? a loose wire will cause it to think its more pulses than what the tach on the fan is reading, hence the very high number. That fan should be around 6000 as well. The sensor in the fan might be bad too. I dont think in the last 35 years of any electronics I have used that had a tach on the fan I had it not working, but never know.
inspect the cable end and see if the wire is crimped onto the metal pin inside the connector, and make sure the pin is seated properly in the connector. You can remove the pin/wire from the plastic connector by moving the little edge of the side of that pin so it slides past the plastic of the connector. Like a small tab. I would look at it and make sure there is contact between the wire and the metal pin, and make sure the opeing op that pin is not too loose that it doesnt actually contact the pin on the control board. Like " Throwing a hot dog in a hallway" X GF told me that.. :-)
You can try a fan from the other miners too and swap it out to determin if it is the fan or the control board.
Update the firmware should be first.
|
|

|

Check the yellow signal wire for that fan, I believe the yellow is the fan speed ( tach) sent back, and if its reading 0 on the web interface, there is a problem. Download the newest firmware from bitmain. I use only the Autofreq one dated November of 2017

Help with fan speed on Antminer S9
I have 4 S9's that run smooth and you hardly ever hear the fans on any of them speed up or slow down.. (some with auot freq, some without)
I have another used S9 miner I am installing, everything is great, except the fan speeds up and slows down every 15 to 20 seconds, slow, fast, slow, fast..
Any thoughts or ideas on why this is happening and what I can do?
There was a post on bitcoin forum about editing the fan speed thru HTML and I tried that...set the fan speed to 70% (according to the kernel) and it is still doing it...
Really, really annoying... There has to be a workaround somehow... How can some do it and some not?
Looking for any thoughts or ideas that might help...
Thank You!
Mine On Dude!!
Hmm another crazy fan story... Check that the exhaust fan is plugged into the plug closest to the outside of the control board. ( Ie close to the edge of the board) The intake fan should be the one further IN on the board. I did that with mine, and the ones that were changing RPM did not do it anymore, well, on the odd occasion they would. Air at 20 Deg C expands when heated to the 45 DegC on the way out..... so the exhaust fan speed has to be faster. Also, undo what ever you did in the config file. Fan speed has to be controlled by the controller since if it gets hotter, it will have to go faster, if you set a limit of 70% you will probably overheat the thing one day. |

It is a perfect ebay item. Easily triple your money.  ahahah AWESOME! But here on their tweet: https://twitter.com/BITMAINtech/status/961166562118975488 Long term running miner... umm yeah, you never get your money back.. that's why it will always be on.... Fawk... these guys! EDIT, I should order 5, and peel off the stickers from my S9's and Sell them as S9's.... ahahahahh EVIL! |

Ok, I just got an email, cliked on the link, read specs, and was like WTF.. whats it do? Just a simple mention of SHA256 is all that is needed, the A3 has Bake2b on its spec page... So essentially they are dumping junk... NICE! There will be suckers that buy these. |
|
|
|
|
Well if nothing else, it will heat your place about the same amount and the initial cost was significantly less... Why would anyone buy this even at that low price.. makes no sense.. ( If it is a SHA256 miner) Maybe its something else? MAYBE a 10nm chip in its early stage.... and they could only get 4TH out of it... first prototypes are sold off... who knows
|
|
|
|
|
Umm, has anyone actually read bitmains page on this.. no where does it state what algo it does... so where did people come up with that sha256?
