One question guys. I Planing to buy Antminer S7 - batch8. I dont know why is this batch overclocked on 700m and hiting "only" 4.7Ths? Previous batchs hit this hashrate with only 600m-625m. Is this some bad batch or what, I suppose b8 unit will heat lot more than previous.
Look at the number of chips it is less on batch 8 from batch 7 and previous batches B7 162 @ 625mhz B8 135 @ 700mhz what I don't get is how they claim the same power efficency |

You need to lower your price newbie  |

I also prefer the stock coloring but what about having a drop down option like you do for the language to allow both color options, that shoul dbe pretty simple right?

Some Compac Sticks can be overclocked harder than others mixing these low performance sticks with higher performing sticks will start throwing out restarts. MY setup has all my good sticks on 1 hub and the few lower performing ones on a separate Pi and hub just to get max potential out of the good ones. Best advice is to tune each stick solo and see what you can get it to do. Label it and mark the clock and voltage max you got it to run at before crapping out. then try 2 sticks at a clock you know they will both run then try 3 etc until you either max out the hub or don't have any more sticks to feed your hub
Thanks for the advice  I actually just tried that "sad" one running solo without any others in both scenarios and it just stays green solid wont has and returns errors as above. The worst part is that they were all running great at top speed earlier in both the 2.0 and 3.0 hub and in minera  300Mhz is pretty high i don't have any clocked that high i would try 250-275 range first your USB hub might not be able to support that much power you also will 100% need additional cooling for them to stay stable that high. the default clock is 150mhz so you're pushing twice the amount of power as stock |

So the next release of our firmware will have loads of updates. I do believe its the biggest one yet. So to tease you all Im giving you a sneak peak at our new wardrobe: Check THIS out!!! (Click to zoom in) https://imgur.com/a/dfEVNFeedback is welcome. Vegas looking forward to it any eta on release? I would love to even give you an idea, but so much has gone into this release and so much of it still needs to be tested and tweaked. The best we can do now is keep you guys informed of the progress, and that we will do. How do you like our new wardrobe?  (Click to zoom in) https://imgur.com/a/dfEVNVegas Looks very nice and clean  |

no way I already have a huge amount of scrypt miners that are much more efficient then those only looking to sell for BTC would consider other forms of Crypto LTC
|

These still haven't sold? Or is this thread dead but someone resurrected it. Zombie sales thread! Watch out! I still have 5 S7's for sale no one made any realistic offers but if people are still interested they are still for sale |

thanks, Im sure we aren't the only ones experiencing this issue. If you were ale to upgrade mutiminer and get good results, then i doubt it would be "trivial" keep me in the loop on your findings. My advise would be to used the minera Operating system on a Raspberry Pi with Compac Support I have dozens of them running over 15GH each for days with no issues with this setup. If you're using the wrong software the system will see it as a U2 stick and not hash at the correct speed |

I didnt know it was 2019 yet you must have traveled back in time in your time machine |

what's you'r asking price for an S7?

Just tested loss of internet with my batch 1 S7 and my batch 3 S7. I run with a proxy to combine all my miners to a single network connection. This runs on a local machine. I left my LAN connection from the two S7's to this machine. Then I disconnected by DSL link. I continued to monitor the S7's with their web interface.
For the first 10 minutes, the proxy continued to fool the miners that all was well. After about ten minutes the S7's started beeping. Checking their status, both showed the connection to the proxy server as dead. The 5 second hash rate dropped rapidly. Both S7's have their fans set on manual speed at 40%. I left things this way for another five minutes, observing that the fans continued to spin at their normal speed. The chips cooled down.
After another 10 minutes, I reconnected my DSL service and established pool connectivity. Within about a minute, both S7's were back to normal, showing a connection to the local proxy and the 5 second hash rate building back up.
If there is an overheating safety problem with the S7's either:
1. It does not affect my two units
2. It is intermittent and may hit my two units some time in the future if there is a network outage
3. I may have bypassed the problem by using the fixed fan setting.
I am using the firmware originally supplied with the two units. 1.5.3.0, file date September 15, 2015.
My five hours offline was due to a crashed Internet. I was away for weekend and got back seven pm tonight. We had something in common my s-7 was set to manu al fan speed. Like you I am using the firmware originally supplied with the two units. 1.5.3.0, file date September 15, 2015. So manually setting may allow for safety any way to get this original FW file the new file from the site just broke my miner I highly recommend others take my philosophy on Bitmain updates on miners that don't use SD cards and can't be reverted easy (C1, and S4 both were great with SD). My motto is if it's the miner is working good and no big issue update, or big feature release. I would just keep the current. If it works great... not always best idea to change. this sucks I never had this problem with bad firmware before i have owned almost every miner bitmain has produced, i am dglad at least its only 1 unit i tested the update on and not the whole fleet |
