Which is the ideal temperature board for BitMain S7?
At 60C i get just about full TH/s, about 5-10GH/s "loss". At 45C i lose another 10GH/s. So i like to run mine anywhere between 45C and 60C. I would tolerate 60-65C on bad days, but i really do not want 70C+. Some people run these at 80C fine, though. At 80c?? For how long? It must run 24/7 |

soon end users like us, with little power will be left out, because it is diff is growing too will grow more and more, now with 20 th / s not going anywhere (I have 4 x s7), and in a few months, no They need any more, for heating only
I must only recover my roi 6000 Euros, then I sell everything and leave the world of btc final
Just like me, going to get my ROI asap and then leave all this to the big sharks. Home mining its dead. |

With that amount i would buy a usb stick miner and save the rest for beer |

I'm moving in. Since I started, I never solve a block yet. Hope I do here  I should be at full throttle in a few hours. I've solved a block 48h after joining this pool, in fact it was my first block EVER since I started mining in late December.  |

BLOOOOOOCCCCCCKKKKKK!!!!! |

Are you quitting mining or what?!?!? GOOD LUCK with your sale!  |

I do not understand why sometimes my 4 x S7 lose power, and then go back,
well down to 3.20 th / s
wrapped I have to reboot to fix.
I do not understand it depends on the pool or from the miner
it's normal?
You need to check if there's any error in kernel Log. Also test it with only 1 hashing boards connected at the time until you discover the faulty board. It could be a PSU problem, so, switch it with other you have. In my case, I was using 2 PSU's in my S7B8, EVGA G2 1300 to power 2 hash boards and a NOX 850 TX to power one and the controller. I've noticed that the board connected to the 850TX were not getting enough power to hash at 100% (was getting 3.5TH-3.8TH in total and the hashboard were 10 degrees Celsius lower than the others ), so, I switched the PCI-E from the controller with the 1300G2 and now its working perfectly! |

Yeah, its fine now, thanks! |

It seems that they only accept BTC now, so, be careful...

Kano I've been using the stratum.kano.is pool in first place and de.kano.is in second, but my connection to the DE server its about 100ms faster, should I move DE to first option?
I'm asking because DE pool server its still in beta, right?
Thanks.

ITS BLOCK FRIDAY!!!!! |

I've burn 2 LEPA 1600PSu's in my S7, the first one worked for about 5 minutes, the second not even 1, replaced it with an EVGA 1300.
Its a shitty PSU, Tupsu warned me, he have burn some too, but I had already purchased it...
IMO you should get a server PSU or an EVGA G2.

Looks like they are still keeping up to date with the scam and everyday updating the order status dates.
Probably a script that do it automatically |

The main "problem" of this miners its the fact that they need about 3000W, and an S7 only need 1300-1400W.
Because they are from 2014, some of them have some dead Asics, so, they only hash from 3.5-4.2TH, that's what happen with mine.
Regarding the noise, at full speed they make almost the same noise as the S7, and some S7's at full RPM speed, make that high pitch perturbing noise!
SP30 are rock solid, very well done, but they had their time 2 years ago...

I received 2 replacements for dead boards that I sent to Bitmain. Within a couple hours one of the boards is dead again... What a waste of $ and time. I know their response is going to be for me to ship it to them again for repair, because they did so well at gaining my confidence the first time...
Oh man, that sucks  Are you using their power supply? |
|
|

BTW, folks...the inventory's getting a bit low. Someone go to the Block Store, please...  Not my time to give one, I already did it 2 days ago! Who's giving the next one? |

After setting up proper monitoring (screw you, Minera!) we found out our HW error rates are way low, in the order of 0.0018%. So thrilled seeing such low numbers.
As for the temps, our cooling setup isn't entirely completed yet. What is the temps you usually "accept" your blades to run at? I was seeing 63c on some miners, is that within reasonnable range? It's safe up to what temps?
Thanks for the help!
louiseth1, what are you using now to monitor your miners? You are using Nagios only to check temperature, right? Thanks. No, I am using Nagios with a set of custom plugins I have made pulling the cgminer-api of the S7's. I also graph all of that in PNP4nagios, graphs which then get included in our in-house "farm management" system. See an example below:  Ahhh! Need to check that out, thanks for the info! |
