So how am i supposed to open it up? That would make it pretty easy to get a couples of quick measurements.
Don't know the answer to this, but I have read that you can remove the fan without breaking any seals? Should be possible to measure the voltage with the fan remove? Rich Think about this: If something goes wrong with this unit, they (Bitmain) will have you take the fan and back plate off of the unit. If it comes down to having to send the hashcards back to them (Bitmain), they have you remove the hashcards and send the cards back to them. They do not allow you to send the housing due to shipping cost. Just think about this. |

So, could you guys post ur hashrate and temperatures?
I'm pretty sure you get lower hashrates if your temps are below 45-50C.
At the moment, some of my S7's are getting cooled by direct -17C outdoor air, which keeps the temp on the boards at 33C (Thats what the sensor says anyway.., not sure if this is accurate when getting blasted by -17C air). The hashrate avg is 4.7TH/s @ 625Mhz
Some other S7's are "cooled" with indoor air, which keeps the temp on the boards at 65-70C, these are hashing at 4.99TH/s avg. @ 625Mhz.
The ones cooled by outdoor air used to hash at 4.99TH/s as well.
Conclusion:
Board temps below 45-50C = Bad? ^^

it's batch-dependent, or so it seems. |

I have found it to be generally true that all of my antminers (going back to at least S3 is when I first noticed it) get better hashrates at higher temps (to a point). And what I mean by "higher" is also model specific. I remember setting some of the S3's so that the hot air coming out of the PSU was directed at the intake on the miner because it improved the hashrate slightly when they were running in a room that was 60-65 °F ambient. I should maybe also point out that on my S3's I had removed the blue fan wire so they ran at 100% fan speed all the time as well. I have an S5 located in a basement crawlspace (that has vent opening to the outside) that gets lower hashrates now that it is winter and the ambient temp is lower where it is. I am not sure what the optimal temps on the S7's are yet but looks to me so far like in the 60's as reported by the GUI is where I am having best results. |

Anyone have a S7 (Batch  that requires reboot daily as it would just fault with the RED light, but after reboot, it would work again with no issues? P.S Different topic and I know it's off topic but figure all you S7 pros are also S3 pros. Is there any other way to do a factory reset on the S3 other than hitting the reset button? I've hit that button 15 times, with different power cycle etc, but I can't get it to factory reset nor get the Red light to clear for me to connect it back in via DHCP |

As for recoverable chips, yes, the chips contain gold. A very minute amount of gold. But, unless you know how to extract that gold, which happens to be a toxic, very hazardous and creates hazardous waste extraction process - not something to do in the home.... and have a significant amount of the chips, that ~VALUABLE~ aspect is out of reach of most people.
No i'm saying people buy these to extract the chips, not the gold from the chips and then run the chips on custom PCBs. Each working chips are probably worth 10+$ Which are recoverable from dead/burnt boards. |

the beeping on internet loss has been something that antminers have never had an option to turn off.. what i have done on my s3s and s5s is put some electrical tape over the speaker. its pretty easy, very effective, and can be removed. |

At this point is batch 8 or 9 the best deal? With batch 9 shipping in couple weeks seems batch 8 is too expensive for when it actually ships and delivers right?

not sure how the numbers add up but my b8 shipped next day and was delivered two days later, i.e. sooner than the website states although b9 could ship sooner too |

Unless you have a B8 coupon. |

Batch 4 was plugged into a 1300 watt ATX which was plugged into the wall. The electrical circut could be turned on/off with a switch. Without thinking i turned off the switch but then immediately turned it back on. Now my powersupply wont turn on at all. Any idea what happened?

If you are using the bypass on the mobo plug just pull it off and put it back on... |

if the PSU reacted by 'tripping' to the power loss, often they need a 5minute cooldown period before they will actually turn back on |
