Has anybody be charged with customs when just receiving one miner at a time? I feel that there must be a value threshold where the customs fee applies and just one z9 mini (especially with coupon) is below that.
I got 3 minis delivered today by DHL. I was charged $42.20 for 2 but no charge for single one which was on a separate order. I am getting more by FedEx tomorrow and will know if I have to pay a duty or not. All are shipped to a residential address in Southern California. I guess first 3 minis slipped through customs, today's 2 shipments of 2 minis were assessed $381.87 and $$428.59 by DHL. I am afraid of what FedEx will bill for 8 minis scheduled for delivery today. |

for TP-Link smart-switches HS100 and HS110 i can recommend the homeautomation-system pimatic. it can make any rule you want, for example if power consumption is less than 300W it should switch off/on etc.
they seem to draw full load when they crash for me. I havent check specifically but the bar on my UPS load meter doesnt change. Will the hs100 report power draw? Didnt think it did. Im going to have to try that. Best to use a pool that alerts when a rig stops sending shares. Then reboot through a smart plug. Mine haven't froze since I upgraded to new firmware, but in the past I was remotely rebooting through smart plugs. |

For sale? Probably. For use? It's the same hashrate/power consumption per chip, the mini will continue to be profitable at the same ratio as the bigger guys, just less on a day to day level.
Also Z9 mini is realistically the only ASIC miner for mining at home without any special investment in electrical installation (even if you a have a few of them). The noise level is border line tolerable and it is using not much more power than GTX1080Ti (with the price of second batch with coupon, comparable as well) Not at all, pretty much all Bitmain miners are usable at home without any electrical mods (provided your house doesn't have pre-60s wiring still); any 20amp circuit will easily suffice, and most of them run fine on a 15amp line. That said, ALL miners are more efficient on a 220v line, and the A3 and S9 both require their own dedicated lines (I assume the Z9 biggie does as well)... Make sure to use a psu that will function on a 110v line at the wattage you need. The A3, T9, and the S9 are the only Bitmain miners I know of that this is a concern for. I don't have an S9 or T9, but for the A3 the bitmain standard PSU worked fine on 110 in tests, but I didn't want to risk it and powered one of the cards with an old PSU pulled from a dead tower. Yea the power draw on the mini's should be more than plenty with the 1800w antminer psu on 110v, double check though. I have mine with a simple 800w corsair on 15a 110v circuit. The mini draws like 350W overclocked. You can likely run three of them on one APW3++ (though it's rated for only 1000W @110, I've never had a problem going over with any of mine--not suggesting others do it, just saying). More like 420 watts at 750 MHz using a single Bitmain APW3+++ per Mini. |

Interesting. Do I understand you correctly that with the latest firmware, the miner automatically reboots if it goes to zero hash rate? Correct. |

enjoy the full disaster of mining!!!!
My A9s and Z9 minis are still puling in $60-$70 and $15-$20 per day per miner respectively. I am enjoying the loot indeed  |

Since everyone is waiting for someone else to try the new firmware  With the new firmware it took about 35 mins for the A9 to ramp up to 50 ksol, but hash rate graph was much smoother than before after that. Fan speed is still between 15-25% and share accepted rate is 94-95%.  But default performance is "factory". Is this ok ? Mine are on performance mode. |

I had to stop last night during benchmarking since after 40 mins the rig was at 30/114. Rig has 10 1080 Ti EVGA SC2 and pentium G3900 with 8 GB ram. I am planning to give it a try later today. Is there a shortcut or ways to bypass benchmarking? Maybe use GPU specific known settings?
With 1080's you shouldn't have to benchmark at all...were they not filled in for you? They will automatically adjust as you are mining I tried but got a message need benchmarking for at least 2 algos before mining can start. |

I am trying to install the miner but getting the same message in 2 different rigs.  |

Looks to me like the power supply failed on that hashboard. I would guess one of the FETs failed and took out the switcher.
You may be able to get it working again by removing the bad power supply chips, and running on just the remaining power supplies.
I sent the board for repair, but Bitmain said that the board is not repairable. I am getting a replacement board for $200. |

Zcash difficulty took a pretty big drop today. No clue why but I’m going to enjoy it while it’s here.
There are other equihash coins - might have been a shift to one of those. Could also be some GPU miners pulling rigs due to low profitability, or shifting to other more profitable coins. Could also be normal "luck" variation. I suspect it's a combination of "all of the above" though. Agree with your points. As a conspiracy theory junkie it’s more fun to think bitmain is shutting down their units after testing , in order for them to be packaged and shipped. Don't forget the innosilicon beasts http://www.innosilicon.com/html/news/26.htmlsupposed they just did a big burn in of 1000 units and packed them for sales that is 50,000 x 1000 = 50,000,000sols or about 70000 1080ti's so 70,000 x 700 = 49 million worth of 1080ti's to be replaced by about 10 million in A9's so 49-10 = 40 million drop in the value of 50,000,000 sols of hash power most of this is on zcash developers and not having 2 or 3 forks ready to go. Asic resistance for any new coin is pretty simple just start an algo/new coin with 2 to 3 forks ready for action. well to all that jumped in on the z9 or A9 good luck. I went to the forkers I am mining some BTG and holding my own. I also am hodling: BIS and RVN I went with A9 and Z9 route and sold my Furys and 1070 Minis, only kept 60 1080 Tis. 2 A9s and 4 Z9s replaced my hash at probably 1/4 or less electricity I was using before. All are mining to a single address. All has been mining for about 2 weeks except for 1st A9 which is mining since July 9. So far all 6 have mined 43.53619192 ZECs or 60% of total invested. I am very optimistic that these will recoup initial investment in a month or two and then mine profitably at least till the end of the year. |

Coordinate with Inno and get their banking information and place your order with them. Then go to/call your bank to send the funds. Otherwise move money to exchange and buy the crypto and apy or you could even use our service if you like. Regardless you're looking at approx 5 business to move funds to inno from a ban no matter the route.
Ok, thanks for info, I will just have to go into my bank. Can others vouch for legitimacy of Innosilicon.com, I know the company is obviously legit, but if those of us considering pulling the trigger, it would make us feel warm and fuzzy to hear a few others who bought direct (with their slightly unusual payment instructions), and can instill some confidence.  I have only bought 2 A9s from inno with BTC, but I know a first time buyer who bought 20 batch 1 (20x$10k) and paid by wire. No issues at both times. |

yours is a lot more stable than mine. have you done any changes to the PLL? are you running performance/balanced?
hmmm i am realizing right now i did switch out the powersupply to use an atx evga 850bq...maybe that has something to do with it. i will try to switch back to the bitmain psu tonight to see if it helps stability.
I am running in performance mode and using Bitmain PSU.
What coin do you mine? How much you get per day? Is it more profitable then nicehash?
Thanks
I am mining ZEC. Not sure about the payout since I have 160 kSol pointed to the same address. NH is good also but you get what others are willing to pay minus NH fees. |

if miner resets to defaults after editing config file, you probably have a typo somewhere. can you tell me what kind of hash rate fluctuations you get? here is what mine look like after 15hrs runtime using 1350PLL and VID 170: https://imgur.com/4FVy3Yj(zencash @ suprnova) I feel like hash rates fluctuate more now...even though temps are colder. I dont really see a boost in performance. can someone please post a screenshot of their admin page so i can see how their device performs compares to mine? im really frustrated that there is no good way to gauge performance right now via hash rate. yea, i can estimate that i am getting the profit i should from my miningpool, but i cant verify what my real hashrate speeds are and that means i can also not verify if these PLL clock increases or voltage increases are actually doing anything. Here is an update on mine from this morning. At one point my miner hit 80ksol/s according to this chart. https://imgur.com/a/59Zt4xzIt almost seems like something is throttling the performance of these cards This is what mine looks like and seems pretty good to me. I am using the current firmware which is actually the July 6th version. Drop before 11 am is when I downgraded the firmware.  Is hashrate improved on pool side? Which pool are you using? Flypool, poolside hash rate fluctuates between 47-51 but payouts are always equal to or greater than what is expected from online calculators. |

I decided to test the mini 1 last time before sending it to Bitmain. I tested 1 hashboard at a time and and it turned out 1 of the board was causing the PSU to trip. After opening it up, found the burned hashboard. Mini is hashing fine with 2 good boards now. 3 other Z9s and 2 A9s in the same server case are running fine.   Server Case, it is vented on top with a 1500 CFM QC-ES-1500 fan.  |

Update:
Still running errors free at 750M. Hashrate stays even but Zencash mined per day has dropped a little to 1.35 Zen a day. Probably due to new Z9s coming online. Getting closer to ROI.
It would be interesting and helpful to the community if one of these days you report to us if and when your Z9 ASIC dies. I would certainly find that useful information and reward you with some merit or some other way if possible. Knowing the limits on these machines and why bitmain only shipped with lower default settings is a intriguing. 1 of my Z9 suddenly died, it was running at 750 MHz for weeks. It is now not responding after power up, no LED activity or fan spins. Tried with different working bitmain psu with no luck. What were the chip temps? Anywhere from 68-79 C depending on the time of the day. |
