Why did they sell it at such a high price?
the simple answer.... because they can. The market will bare it. At this point there are really only 2 options for home miners... Bitmain and SP and Bitmain is less than SP. But you cant even buy antminers now... Can buy C1 and S5. Just no more S3. S5 is sold out. Its just for the holidays, everything proper shuts down at this time. |

So.... anyone have any idea how he's achieving 25%? Honestly the only way I can think of getting a discount this large is that he's ordering on stolen credit cards. And that's not an accusation, that's just a .... how is this possible.
He could be using social engineering to be getting refunds/partial refunds. Not the same crime but still a crime and probably more unethical. This is also speculation however there is not a realistic way he can get such a large discount without breaking the law. That's what I was thinking. A few % then he's using an efficient voucher something something, 5% then likely adding in affiliates disruption, but 25%.... If someone was getting a 30% discount, they'd be offering 5-10% off not 25%. 25% just sounds like they're getting 100% off. |

I've been doing some calculations and at the moment it seems that nobody is near ROI with this miner.
If you received it on Jan 1 2015, and you had FREE ELECTRICITY and you sold all your BTC during that price spike on Jan 25 2015, you would have made a profit of $165 till todays date.
But its rare that everybody sold on Jan 25th at ~310BTC/USD and rare that most have free electricity.
Taking the average price using moving averages of the last few weeks and average power rates you would have made only $60 to date with this miner. Why did they sell it at such a high price?
Because many people do have free or next to free power, and most people aren't looking for a 50 day ROI. |

fans for S1 and S3 has lower RPM and it is less noise... At what speeds are your fans running at 350mhz? I am currently doing 4080rpm @ 56C with the stock S5 fan. Trying to find a decent exhaust fan to low temps for find an alternative cooling method. Vertically standing i drop temp by 1C average. I must say I have a new found respect for the S1 fan with its noise levels.  And the S1 was ~350W rather than 600W. But still, S5 is a hell of a lot louder. |

Think there's a capacitor knocked off each board? Every one doesn't work even when tested individually, according to his last reply.
No, the other guy's problem was ONE knocked off capacitor causing the entire chain to not mine. |

If that's an old-version BE controller (I think they fixed it on the one shipping with Prisma 2.0 now?) the stratum implementation is severely hosed and it won't work with most pools. What version controller are you using, and what pool?
slush. I have two prismas on hand. and my BE controller OR raspberry PI work fine on the other prisma...... (we'll just say prisma1 works fine) but prisma2... boards will all register OK but none of them will "mine" performance just reads 000 .... doing an individual board test to troubleshoot.... all boards individual won't perform either.... but they register just fine.... changed settings on pool to minimum difficulty 2048 (just to troubleshoot) - still no PRF.. ^^^ above testing was all done on slush pool (mind you that prisma1 runs fine on slush pool) He had a capacitor knocked off, which when he taped it down again got the entire board back up. Inspect your Prisma for physical damage. If you can't repair or solder it, bypass that board for now. |

8000 characters? Do you want to write a novel?
What about 5000 for Hero? Its surprising how little 4000 characters actually is. I was the one who asked Theymos to increase 2k limit as I was hitting the cap with plenty of real estate left in the actual sig space, even at 1280px wide. |

I think I found my limit. I have an s5 running 337.5 with only 4 hw for 24hr period. It's hashing at 1.1Th/s but sometimes it dips to just under 1Th/s. Why is that? Is it due to power irregularity? Also, at these settings to he temps are 66 and 68. I know that is high for the miner but I'm not getting hw errors. So I think this is stable. But the temps. I keep reading that the miner needs to be below 60. Is that due to instability and hardware errors. I once thought heat was related to hardware errors but with this discovery it is inconclusive. So, all you really knowledgeable people out there, is is safe to rum at or below 68c? I have a push pull fan system and have replaced the stock fan. It's not quiet, in fact, I have to make another fan changeout before the week is over. This fan setup is too loud for the fam.
When I make the can switch I'm not going to be at 1.1Th/s but I would like to be close. I'll be watching the temps and if I'm stable and I can run the miner in the 60's then I could get a few more hashed out of it.
1) What power supply make and model are you running? 2) Are you seeing the varying hashrate on the S5's status page or your pool's status page? 3) What pool is it at? 4) Please can you provide a screenshot of the S5's status page? Temps are best kept under 60C but its not a "its going to blow up" situation if below 70C. You may shorten the lifetime of your S5 by running it that hot however. Hardware errors shouldn't change appreciably between 60 or 70C either. |

What is the idea around the static blades on the S5 fan?
I read that it should direct the air flow to some extent. These blades have a twisting effect.
I am trying to drop the dbs of the fan with an extra pull fan, but to no avail. S5 fan does not drop below 3680 RPM.
Deta fans and Silverstone fans will take 6-8 weeks to reach me.
You'll get different answers on this but one of the simpler ones is it increases static pressure per W. |

It's working!!! Woooo hoooo! Thanks  I will contact you to donate some coins as soon as I've mined some  Glad you're up and running but no donations necessary. |

I'm sure there is no shortage of folks who would want to do that job. Nah, mo' money mo' problems. |

Just an update on my PSU issues.
I ran the S5 fine on the AX1200i for a week, but wasn't too sure about running two S5s off it. I have an energy meter at the wall and the max wattage for 1 x S5 via the AX1200 has been 610W.
So I've RMAd the AX1200 and gone for an AX760. I have another S5 now, so that is running on a CS750M.
All good so far.
Anybody know what the best difficulty setting is for an S5 ? it seems to like 4k and hate 2k.
Cheers
1024 or 2048 should work well, higher than that and you're just burning shares on discards. |

I have replaced a PSU with Corsair RM1000 (80+ Gold). Now the power consumption at the wall is less (662-666 Wt), and HWE has been reduced twice (from 0.027% to 0.013%). It's all after 11 hours of running, will see what happen next. p.s. seems that after "halt" command the power consumption is about 150 Wt... That's actually rather high for a stock S5, they're usually in the 580-600W at the wall territory. Have you got anything else on the PSU? |

My S5 lost half its hashrate today. Its been about 8 hrs of reduced cycle. This is my first bitcoin miner. How should I approach troubleshooting?
Switch the power supply off. Count to 20. Switch it on. If this doesn't help you might want to try another PSU, try powering one blade at a time, swap controller cables, swap controller ports. It`s not a PSU issue, i have 2 s5 on 2 different PSU A 750w and a 1000W, and yes they drop to half speed alot ramdomly, ( NOT OC`ed ), sometime after 10-20 mins they will go back up to full speed, sometime not, and sometime totally freeze up and need a PSU reset. i would have to assume it`s a firmware bug on first gen firmware or Jan 7 firmware? It happened to me on first gen, not much or very rarely on jan 7 firmware. Yeah the latest firmware pulled out the majority of the bugs in relation to blade dropping but it seems not all of them. Recommended to upgrade to the latest if you're not already on it. |
