Antpool does not short change but the transaction fee is kept.
Currently, it is simply the bad luck day. Nothing more and nothing less.
Hope tomorrow will bring us more luck!!!

If you are concerned with your unit not able to control the temperature, please contact us as soon as possible for a possible warranty case. Possible bug in firmware. A critical one.
I had my pool drop out on me, they were having problems and I was disconnected, so the miner wasn't hashing. The fan slowed down to almost like 100-200 RPMs but the temperature kept rising. The fan NEEDS to keep running to keep the ASIC chips cools weather hashing or not it seems. Temps went up to 75-80 so I turned them off right away to let them cool. Bitmain, you need to review the firmware so that when the rig gets disconnected from the pool it doesn't disrupt the fan speed to keeping the chips cool. If I wasn't home and didn't hear the beeping sound I'm wondering how high that temperature could of went to. I actually felt the heat if I put my hand over the miner. It can't just be ambient temps, because these chips cool really quickly...so something else is going on here. If you want to try and test, pull your ethernet cable out and see if your fan stops or slows down and watch your temps closely.
Once I re-established a connection, everything looks good. Any ideas on this? We don't want burnt up miners, right?
You can configure it to shut off at 80 C but yeah it would be nice to have a control from the GUI. I wish some others would test this. I had this same type of thing happen about 6 weeks ago. The firmware safety net of 80C shutdown did NOT work (yes, mine is checked). When I saw it, one blade was up to 106C. I mentioned this before, here, but with the Chinese New Year timing, I'm guessing it didn't fall on any ears at Bitmain. If true a major fire hazard. BITMAIN can you confirm that the 800 C shut off works. I will be operating my miners remotely in the coming weeks and need to make sure that safeguards work so my house does not burn down. |

If your units are still under the warranty, please contact support@bitmain.zendesk.com with your Bitmaintech.com Order ID and full shipping information with a telephone number for further instruction. 5 out of 5 pumps developed leaks this week. seems the glue on the reservoir housing fails under temperature

Yes Bitmain was the first ASIC Manufacture to start to ship EALIER than promised and continue to do so! I wonder if the first batch of #5 will start shipping this coming week? Bitmain has made it clear when he posts he mentions that he usually ships prior to their "shipping date". I wonder if that was a ruse for a good sales pitch or has some truth in it? I guess we will see. It would be nice to get a surprise at the door this week.
they usually under promise and deliver....... unlike sp tech |

@Kano,
Thank you for pointing these out. Will look into it!
Just realized this was a known issue since December of 2014. Will address this to the engineers again.

If you bricked S5 controller's firmware, it can be restored depends on how badly it is messed up the internal firmware by using the MicroSD card. You can reboot S5 from a bootable MicroSD card with S5 bootable image on them. Once you booted S5 from the MicroSD card, please SSH into the S5 and run this command and it will fix the internal firmware issues. If you are not familier with this process, you can always request a live tech to remote into your computer, create a bootable recovery MicroSD card for you and run this SSH with you. /etc/init.d/pgnand.sh Bootable Image can be downloaded from here: https://bitmain.zendesk.com/hc/en-us/articles/203461209-Jan-7-Firmware-ImageYou can use this file to restore any MicroSD card (preferably 4GB card) with HDD GURU's Raw Disk Copy Tool that is free to download on the Internet. |

M's monitor can reboot the miners remotely, but if the soft reboot fails, it can't reboot. Also, this is a software based solution and not a hardware solution, so when you have to shut it off (Off OFF), you don't have an option.
most of the time, Antminer products with X on the chips will go away, when you do a HARD POWER OFF.
Bitcoin Mining is sadly to say, requires more human attention than running SuperMicro Servers in the data center. Hands & Knee approach is needed
Antminer products will let you reduce as much human interaction as possible, but it is a specialty computer processing unit and requires HUMAN ATTENTION.
At the same time, Antminer has many configurable options and you can still run your own MOD but at your own risk. (Our hardware DOES NOT void warranty for you to open it up and look inside or move things around but when you change the original configuration such as a different cooling fans, different firmware, pencil mod parts into the PCB, often time it will work but when you experience the "OH, SH*T" moment, we may not be able to honor the warranty for you as it was operated outside the safety spec.
if you think you can deploy a farm and just walk away without maintenance and supervision of the farm daily, it will not work at this stage of the mining industry.
Definitely, we have farms that were setup once with a few days of perfecting it, then walked away for months for self operation but that requires hardware and software approach with daily monitoring and on-site staffs for just in case emergency. (Also, all the certification and safety precautions being implemented to include unexpected overheated unit interaction as needed but it is deployed in the way that self extinguishes and no flammable near by)
Warranty wise, any modification from the original configuration will void the warranty or being denied of warranty. It is like Buying a Toyota and replace it with your custom made Tesla Engine in it and blow it up.

Happened to saw this question here... The Block# you are seeing is the Bitcoin Block the pool found. Each time a block of 25BTC reward is awarded to the miners belong to the Antpool, the hashnest customers will receive a proportion of your payout. More info at http://www.hashnest.com or send email to support @ bitmain . zendesk . com with additional questions or list it here Thanks |
