Even more interesting would be whether anyone has been effective at gaining root on this (or the previous) firmware. |

Fascinating...
How did you determine that the PWM 20% duty cycle is correlated to the 0.95V? That seems like some arcane magick right there.
Also, what resource(s) did you rely upon to use Arduino for that dual DAC setup?
Marvelous work there. Will be something else to see how far you get with boosting output.

Nice. I hope it survives as well. Makes for a fine datapoint we might all someday rely upon if we decide to do something like that ourselves.
Thanks for mentioning it. Cheers!

In just one week the difficulty has gone up 150% with Grøstlcoin. Seems to me that anyone buying into ASICs now must be, by definition, hardcore supporters of this coin given that the profitability in terms of investment is now inexorably becoming infinitesimally low.
In time the true apostles will be the ones with their skin $€ cash in the game and those have now become the BK-G28.
God help them all.

I can just warn everybody from doing business with innosillicon. I Ordered 2 A9 Zmaster for 7000$ on August 22nd and paid directly with BTC. Since then the Orderstatus sais "Processing" but hasnt changed since August 24th. Multiple Questions to the support regarding my order dont get answered at all. Stay away. I will just continue doing business with Bitmain at least they are professional when it comes to buying and delivering.
...
If i dont get any reply or the miners during the next days i will take legal action against this company and inform as many others i can about my horrible experience with Innosillicon.
I completely agree with you that Innosilicon is an absolute joke of a company both in regard to the product and to the customer service facility. They happily sell garbage and then just ignore you once they have your money. What's worse is when you finally get their attention but the same people just ask you for the same thing over and over and over as if just stalling for... what? more time? To do what? Our group purchased a quantity of these and while they were delivered on time, 3/4 (three quarters!!) of the delivered units had performance FAR BELOW that advertised (28-39KSols as opposed to the advertised 50KSols). Innosilicon Simply Does Not Care. Six remote logins to our administrative computers, four useless firmware upgrades and innumerable screenshots later and they just stall and stall and couldn't give a damn. Bitmain Exists Only To Plunder The Mining Community
With that in mind, please do reconsider your choice of BITMAIN which has amply proven themselves predatory in too many different ways, most egregiously with secret pre-mining: https://medium.com/@salva.enkidu_89587/how-bitmain-indeed-mines-coins-in-secret-2ea179e7ab75The existence of a company such as BITMAIN has historically already caused more contention and waste of human and natural resources than even other eminently criminal organizations such as Micro$oft, Adobe and Apple. So, please Do Not resort to Bitmain. |

I found weird thing on A9.
If you leave webpage open to miner, productivity for miner will be lower... Maybe because web-server is using a lot resources? I found with Nicehash, if web-page to miner opened it disconnects miner from pool very often.
Has anyone been successful in disabling or changing the timed, auto-logoff feature from the html interface? Frustrating to say the least. Perhaps if anyone has a suggestion on where the logout variable might be found in a configuration file somewhere? |

Hello guys
I have FF D18 home silent dcr miner, this miner has no website, I want to upgrade firmware, anyone know about new firmware, how do I get please
If you're looking for some other salient response, you're definitely in the wrong place. It's unlikely you'll get anything useful here. Perhaps try: https://bitcointalk.org/index.php?board=160.0Good luck. |

So yeah, remember to change your passwords if you NEED to go directly on the net with these. I knew it was dumb, was just kinda curious to find out if things were really that bad out there. Im going to report the username later, ...
Where would you possibly "report" this to? Nicehash is the home of persons who literally do not care. In my experience, no one (absolutely no one) will care about your report. In order for you to achieve any justice whatsoever, you'll have to hack the lowlife yourself and get all those coins back. |

Congrats on deciphering the root password...

I got an mail, that the Fees will drop to 0%
Is this correct? If so, when is this taking place and for how long? Thanks. |

Are there any good reasons we're missing such that we'd pay 2% to Slushpool, when most other pools are 0.9 - 1.0% ?
We believe that our advanced worker management and device monitoring is pretty good reason and this functionality can save you more money at the end. But of course – the decision is on each miner. However we know that we are 'too expensive' for some miners and we are thinking about making changes. This is a fascinating claim. In what ways can this save money at the end? Does Slushpool have inband device configuration or adjustment options? I notice that with these Innosilicon A9 devices one can't even get into the UNIX/Linux shell to kill the irritating HTML-monitor logout tendency. It would be pleasantly surprising that your pool has some way to adjust device operation inband. |

Interesting discussion about hashrate of the A9, we thought we could share some numbers too. On Slush Pool we currently have about 40 A9s connected and they average out at 49.86 ksol/s. We obviously do not know what mode are miners using, however the numbers are solid and very close to the specs. I guess that if you enable the performance mode, you should be well over 50 ksol/s on our pool.

I have
10 Antminer S9 13.5 Th/s ~$450 apiece
3 Antminer S9 13 Th/s ~$333 apiece
Bitmain 1600w APW3++ power supplies $75 for one. $100 for two.
All working and hashing perfectly.
Accepting BTC / ETH, escrow only
Prefer to ship USA
Thanks
This is what I received when trying to message you: User 'rubbertoe9' has not chosen to allow messages from newbies. You should post in their relevant thread to remind them to enable this setting. I'm interested in your APW3++ power supplies. What is the condition? |

Did you contacted support to get new firmware dated 6/30? Which pools are you using?
I got stable 46 kH/s for any pools now, with 1-2% rejects max.
Thank you for your comment. I did indeed update the firmware on those laggard A9 devices and indeed the reject rate went way down but the hash rate is still the same on two different pools. Seems like I got a bunch of duds. My friend bought 2 ZMaster and i bought one, and his run everytime more hashes. The only difference was, that he had bigger windows and wide open, i only had 1 windows open and not fully only tilt. And he had also put ventilator directional to the miners, which blowed the air directed to the window. His miner showed also two cards at around at around 64°-65° Celsius, and only one card at 71° Celsius. Mine ZMaster had two cards running at 72-73° and only one below ~67-68° Celsius. So i had everytime in my backhad that it might be caused by temperature 'underclocking'. We brought now the 3 ZMaster to our "Mining Hub" where we suck out the air with 3 axial fans, and with a pipe construction directly from the miners. Now the miner of him runs at 63° - 71° - 64° and mine runs at 67° - 72° - 65° and now i got steady average slightly over 50 k/Sol right now hourly 51 k/Sol, the hash numbers are from the antpool panel. Only 7,07% rejects so i am at 92,93% accepted rate, also from antpool panel. (Before i got 41-48 k/Sols, and higher temperature like mentioned before) So guys what i figured out is what you might have to optimise or what might cause the problems:
1. Pool :
Some pools have to optimise for the ASICs, since ASICs are quite new for Equihash. So look out for one which says our seems to be already adapted the ASICs.
2. Cooling:
Look at your Innosilicon Panel, it seems to be that the middle card is getting hottest, but the 2 on the side should be below 70°. Otherwise i guess there are underclocking or get to much physical electric resistance caused by heat. So watch out for your temperature and cooling.
3. Network:
I personally had network issues, some switches and some network controller of the asics, can have problems. The Symptoms are that the panels kinda loops in "tunning" but when you look in the logs, you see that he loops at connecting to the pools.
I am still in to solving that problem i ordered a new Switch and maybe some cat5 cables, will see and report how that works out, and if it proves the theory that i might be caused by automatic 100 full duplex.
For now the one originally faulty device, was put in a other network at home at a friends place. The secound one got similar problem after bringing all 3 together, but it could be fixed by just pressing "Update" other Network.
To note, the first days i run mine at home and he run his two at home, and we had no problems at all, beside my heating "problem".I will second your experiences with the cooling (#2). Thank you for the suggestions. I notice that some pools may experience spurious "nicehash" activity where the pool hashrate jumps 100-200%. Then the next block share is less than 50% of the one before. This actually brought up some other interesting issues to explore... |

I had two A9 with 30% rejects, but found a solution. If you guys still have problems with rejects - drop me a pm. I can possibly help
This great BBS won't let me send a pm, so here it is... Greetings, I have a few of these A9 devices and literally HALF of them are crap (31 to 41kSol/s avg hash at the pool.) What kind of interesting solution did you use? Kind regards, Lee --------------------- Wie geht's, Ich habe dieser A9-Mineren und die Haelfte von scheiss davon sind Muell (31 bis 41 kSol Durchschn). Was fuer eine interessante Loesung hast du benutzt? Danke. Tschuss, Lee Did you contacted support to get new firmware dated 6/30? Which pools are you using?
