Have Bitmain any plans on lowering S5 (and maybe shipping?) price?  Shipping is ~cost, its unlikely to change any time soon unless UPS / DHL lower their prices. |

You can use the ~ to set whatever trust you want for any user you like really given they have a reasonable number of positive ratings already. If you don't like it get your fan to support you and change it. Heck band together and ~ the whole default trust list and rebuild it in your own image.
The only thing that would change is your and your friend's perspective. Nothing else would change if neither of you are trustworthy. |

2 s-3's pull about 1200 watts at freq 250 your gear should do a good job running 3 s-3's
I would do a comparison to an evga 1300 running s-3's you should get better watts.
Being realistic, what can we actually test on a PSU without proper DC equipment? "Yes it turns on, yes it didn't explode, yes it powered some miners, yes it consumed this much power". We already know these things from the 100s and 100s of S4s its in. The circlejerk of made up stuff is what needs to change, and it probably will now the guy with 7 different accounts is banned. |

Unfortunately one of my S4 fans (one at the back) died recently. Can you recommend a replacement fan?
If you can't get ahold of the server-esque fans a simple Corsair SP120 works fine as long as put it on the front. The rear fans do the majority of the work. |

Can i ask a clear explanation on what does the 'month' do or its effect? I cant understand it clearly
Brand new trust ratings are worth 1 point, rising to 10 after 10 months have passed. |

After a quick perusal of your trust, I challenge that statement.  I stand corrected. Geez man, people getting platinum mad with your ratings. I still have way more. Or maybe Bick does, will be close. [BFL "competition"] |

Unless they make open pool choices, they become number 1. If they don't make open pool choices, they then have to convince everyone to spend that extra $8 initial and $1 per month in exchange for almost exactly nothing in return.
$1 a month might not sound like much, but put another way, who would "subscribe to the bitcoin network" for $12 a year? That doesn't sound like something that can be sold en-mass. But buying $12/year of lottery tickets ? No problem. There are ways to structure compensation to the consumer that can make this work, even in the face of marginal mining economics. They're not being offered $12/year of lottery tickets, they're being offered $12/year for $3 of bitcoin and a warm fuzzy feeling. |

There is no decay. Ratings grow in weight from 1 to 10, then stay at 10 forever. (If the rated person has no negatives.)
Oh derp, I thought "months since rating" would be counting down for some reason. |

Is there going to be any kind if max score like there was previously (150)?
Currently -9999 to 9999 |

I also completely changed the trust score algorithm to this: if there are no negative ratings
score = unique_positive - 2^(unique_negative)
if score >= 0
start_time = time of first negative
score = unique_positive since start_time - unique_negative since start_time
if(score < 0)
return ??? (orange) Doesn't that mean if someone receives a positive and a negative rating, they'll go negative if the negative is newer? score += min(10, round_up(months since rating)) That seems like quite an extreme decay, ratings after 10 months are worthless? Its going to lead to a lot of reposted ratings to refresh them. |

If it's set up the same way it was here, he's got 8 boards per DPS2000 PSU, which ran fine on the shelf for about seven months.
With the nice chunky 16AWG? Power is the only thing I can think of that would cause an otherwise working board to entirely drop rather than just throw out junky shares. At 300 they'd very nearly tip over the 2KW per 8 boards which is close to max capacity but acceptable. I do remember that the Tubes really desired 8 PCI-E even if the cables could take it so maybe its power but on the miner's side? Could test that theory by putting 16 cables on one PSU and trying it on 8 boards again. If that works then we at least know the cause. |

Board 6 looks to have a few chips out. If you reset or power-cycle, they might come back up. It could be a heat issue residual from them being overclocked. Glad things are going for you.
I really doubt its heat damaged from just 300mhz in a normal ambient, they're crazy good with heat. When I first got one of these I tried to fry it with the fan off. Entire board was at 110C but nope, still mining fine for hours. If we're dropping entire boards when OC'ed and some chips still when at stock it could be a power issue. The boards themselves again should be fine at 300 no problem, so looking towards power. How many tubes / boards per PSU? |

I believe trust system is only designed to mark the scammer.
Part of it is trying to prevent scams before they happen, more so than just marking accounts once its happened. I've not kept up with any of the quickseller threads so no point commenting on them, but there is always going to be a limited amount of crossfire in trying to protect users. If or when that happens, it should be relatively trivial to then resolve that with evidence as long as everyone keeps their cool. |

1) The PCI-E ports on the boards are not specific, they both connect to the same places. 2) If you have the reach, the closer PCI-E on the cable is preferred to shorten cable length. 3) You have 9 boards on the 1st picture and 11 in the second, so that is 7 and 5 missing boards. That could either be due to non unique dip switches in a chain, or somewhere a board is dead and dropping part of the chain. 4) Go through the boards again and set them up in numerical order rather than just unique, then you can trace exactly which is missing: https://i.imgur.com/RWsscqw.png5) Set them all at 240mhz just for now so we know its not PSU related 6) You can recheck through setup instructions here, but it looks like you've got everything for now. Good luck, let us know how it goes. |

Dogie,
I see some people only connect two PCI-E's to the S5. Is there harm in doing this?
thanks,
Rtt
No harm but if you were overclocking it will need the 4 PCI-e possibly. All depends on frequency. Yup, and depends on the AWG of your PSU cabling. 2 PCI-E is only possible on TWO cable rails, and only recommended on 16AWG. |

... but all your PR is centered around tricking people into giving you more money - which, to be honest, is actually pretty standard.
Aaaand we're back at square 1  . I don't think we'll ever achieve decentralisation, its fundamentally incompatible with economics unless someone is philanthropically burning $10Ms for the benefit of others. |

After thinking about it, not so sure this is a good idea. Think about all the people who left Bitcointalk in disgust after $username scammed them. They would never come back so their feedback would eventually become irrelevant and TF would eventually be able to scam again.  Would differentiating between positive and negative feedback solve this? Positive feedback gets expired/removed if the feedback giver doesn't login for a year. Negative feedback stays unless the feedback giver manually removes it. [Discussion] On what basis are trust ratings less trustworthy/useful as they age? A lot of them could be from the days of $3, $30, $100 bitcoin so in today's money would be significantly multiplied. Or is that a bad thing.... |
