fuzzy, Please explain on your "rentals are NOT allowed here" Since when was this enforced?  Brain fart - wrong pool.  post deleted. |

Well hell, their 7 day hash rates tells ya more than that, "hashrate7d": "432T"

Consider a pool with everyone on the pool running firmware that never finds a block, or 50% of the pool running it, or 25%. It will have an impact on the luck of the pool wouldn't it?
Damn straight it would because you have in effect cut the number of miners by the same percentage. That in turn is highly unfair to those running legit (known working OEM) firmware because pool payouts have to be shared with the miners running crap firmware. Again, I'm not saying that the various flavors of modded FW out there are crap but rather that the onus is on the devs of said FW to PROVE that they did not screw things up. Mega pool operators may not mind too much because enough blocks are found per-day by the other miners to keep folks happy but for small pools missing blocks can be the Kiss of Death. That is the sole technical reason why Kano.is bans non-OEM firmware. Once someone provides verifiable proof their FW finds blocks at a rate which is on-par with OEM FW that would just leave GPL license violations as a moral reason to ban it. |

congrats!!
is it apparent somewhere how long (days/hours) it took him to solving the block?
Um, the find time had to be within the target of 10min average per block... You don't get work for 1 block and just keep plugging away at it, the work changes with every block found. |

Some pool operators need to chime in on this but AFAIK, getting shares accepted is only part of the proof. Latency between getting/sending shares, # of rejects, stales and other things have to factor in as well. Again the FUP that Slush had a couple years ago with a VERY large miner being paid $$$ for over a month of bad work caused by a screwed up proxy comes to mind.
Considering that the devs have often stated that some large farms use the modified FW it should be a piece of cake to get proof. Heck, I only run just over 1/2 PH and to-date have hit 10 blocks on Kano.is or roughly 2 per-year since I started running there. Very large farms should be popping blocks left and right and considering most run some sort of monitoring software (or damn well should be), just set it to look for the block found flag and log it.

Have any of them proven that their firmware has been installed in a miner that has found a BTC block?
I've not seen anything to that affect, but it seems like lost of people don't care, even people who purportedly care about BTC
Considering that the cgminer API even has a report found block function, one does have to wonder just why not a single person has bothered to post anything proving said modified firmwares actually finds BTC blocks. Hell, monitoring software like AwesomeMiner lets you set a trigger - Detect found blocks - to log it and notify ya. If folks are so fired up about using all these FW's then take the time to PROVE they work! |

The author of the article is just stating the obvious. Of course the vast majority of machines never hit a block, one might as well state that in any given year 98% of people buying a Lottery ticket every day never win a significant prize. It's how the systems work: If too many win (find blocks) the system goes bankrupt so yes, the odds are stacked against players/miners. Duh!
In my case, since Feb 2014 I've owned a total of 108 miners. Most are of course now offline & replaced by faster gear as the years went by leaving me now running just 26 much faster miners. Using all that gear, to-date I've hit a total of 13 blocks while using pools - 3 at BFL's old EMC pool and the remaining 10 all on KanoPool.
Obviously most of my miners never hit a block before being replaced. BUT -- I have a 'Lucky" R4 (still running) that has hit 2 blocks both last year, 1 out of my 3x M10's hit one and 3x Avalon 841's each found 1. On Kano the remaining 4 blocks were found by various flavors of Ants from S3-S9's. All in all I think I am well ahead in terms of # of miners vs blocks found.

Along those ^^ lines, good article on crypto & the IRS - your 1040 Individual Tax Return now specifically asks if you have crypto transactions. A key point is mentioned at the end of the article (emphasis mine) “The days of not reporting until you get caught are over. Crypto tax guidance is out there, and if you trade crypto, you should report gains and losses,” he tells Decrypt. “If you report something, it starts your statute of limitation. This means typically after three years of reporting, the IRS cannot come after you unless you have committed fraud or largely under reported your income. The main takeaway is that reporting something is always better than reporting nothing.” |

Is there a way to get the Watts per board and total watt consumption ?
Would be really helpful for tweaking to get best J/th
No. Miners have no circuits for reporting current draw and without that 1/2 of the equation (W=V*I) they cannot report power usage. edit: As Artemis says lower on, any firmware that does give watt or Joule readouts are doing it based on the devs testing gear at various speeds/freq/temps to find typical power usage with those settings. From there is just a matter of them guess.., er, extrapolating results from where you have the miner set. |

I put it here because it was specific to the commands and options that were being discussed in this thread.
This thread is for the 921, you were discussing the 841. Yes the commands for them are similar but - for many of the commands the values that the commands accept are different eg: -avalon8 (or 9)-voltage-level and voltage-level-offset and the -freq values. Those have different ranges and step values that they will accept. The 841 thread covers all of the commands and values that the 841 will accept. Here are ones in that thread from PhilTa boot, several of the 841 commands seem to have no effect on the 921 so.... |

Why is this in the wrong thread? Should be in the 841 thread unless you have confused a 921 with a 841... Requested mods to fix that |

Not really.
The S9E is not 'recent', it has been out for 2 years and for the most part acts the same as all s9's. Loud and hot.
For at least the past 4 years all BTC miners have been the same - LOUD. The reason is simple - they suck a lot of power and need the high speed fans to give enough pressure to force air through them for cooling.
The only way you can throttle them down is through reducing the power they draw by running the miner at lower THs via undervolting/underclocking. Simply slowing down the fans or trying to replace them with quieter ones only results in the miners overheating.

High neutral currents is a common problem when running any sort of non-linear load, in this case, scads of switch-mode PSU's. All of them (not just ones from Bitmain) cause it. For powering large farms, using K-factor rated transformers which are designed to accommodate these loads is a must. Ref this from Jefferson Electric. Poking around the Jefferson Electric site I do see that they also carry a line of Harmonic Suppression Systems to use with existing distribution transformers and gensets. |

All very true but it is still odd to see a cluster of miners with some of them running different speeds. What does not help is that which miner ID is which actual miner will change when a miner restarts on its own (or if you reboot it). On mistakenly crossing the updates, if you do that a miner can still be accessed and set right. Just isolate the erroneously updated 821 or 841 from the others, apply the correct MM to it and all will be well again.  |

Most folks who have a firm grasp on Reality were not welcome there...
Personality, methinks the OP was just a 1st class Troll who picked a prime subject they knew would go the way it did.

Personally, I smoke because I like to. Period.
I often fly overseas, longest flight so far was 28hrs portal-to-portal with most around 18-20hrs, I regularly work in clean rooms and pharmaceutical mfg areas and not being able to smoke at those times has never bothered me at all. Even when I am freely able to smoke I'll often go several days without a cigarette just because I don't feel like it. Nonetheless I average 1 pack a day.
Never once has it bothered me to not be able to smoke. I figure that once it DOES bother me - that is the time to quit.

RIP FE. (Can you unlock a thread once you have locked it? Yes, the OP can unlock it anytime they want to. |

I didn't get round to reading it, as the title put me off. What was it about?
Um, perhaps try reading some it... It is still here The 1st post in it pretty much sums up what the poor deluded OP was thinking (HA!) about. From there they just gassed on & on trying to support their belief and prove that everybody else is wrong. |

Love it and definitely interested in a couple as well, no strobe but just lo/hi modes.
