There is a guy that ran BIPS claimed it was hack for more then 1000 coins when coins where worth 1000 bucks say Nov 2013.
I can find a link. He is Denmark company maybe.

You can very easily fix both the PSU and Miner yourself.
Parts shouldn't cost any more than $10 to put new pins on the PSU with a new plug and for a new Molex ATX PCIe plug for the miner.
The miner end may be tricky for him to repair since the plug is almost certainly a through hole component and it looks like it is located under the heatsink. It isn't impossible to do, but it isn't for the uninitiated either. As long as the pins are clean of residue and the cable plugs in to being snapped secure, I would avoid replacing the plug on the miner. Disclaimer: this is based on a photo and my opinion may be different if I was looking directly at it. The PSU end is repairable with some basic skill, but if it is his first time I would recommend having someone with experience do it with the proper crimping tool (these connectors are used so close to their rated maximum that they really need to be done perfectly). All of the PSU ends need replacing if he is going to use the PSU again since they've been through the same mechanical stress that is the probable cause of this failure. I am 95% sure a new psu with good cables and problem is gone. and of course do not plug and unplug much at all. I think I have a photo of the board let me look new replacement board  cap popped from over volt  |

fast rule of thumb
0-3 cent power makes money
3-6 cent power should make money
6-9 cent power may make money
9 -12 cent power making money is possible but you need to really understand every edge and angle of the game.
12 -15 cent power should lose money
15-18 cent power very very hard to make money
18-21 cent power very very very hard to make money
21 and up you really should play horses or casino don't mine
your miner is older and not too good but it makes money with 0-3 cent power about
34 cents a day with 3 cent power
25 cents a day with 4 cent power
16 cents a day with 5 cent power
7 cents a day with 6 cent power
it loses with 8 cent power and above

okay here is what you do.
run ac right into the intake
make sure the fan that blows the air outward is not restricted. So make sure the exhaust is vented out of the room.
Step one
set freq to 700 fan to 70% make sure the psu has 12.5 volts not 12.0 volts
Step 2 fire it up
run it for an hour
check temps should be 50c or less
check fan speed should be 4200 to 4600
check errors should be 0.0025 or less
step 3 jump freq to 725 fan to 70% make sure psu has 12.5 volts not 12.0 volts
step 4
run it for an hour
check temps should be 55c or less
check fan speed should 4200 to 4600
check errors should be 0.0030 or less
keep that pattern of increase.
when temps reach 62c stop
if temps stay under 62 c and errors get to 0.200 stop
a fan setting of 100% is not necessary top rpms are about 4200 to 4600
you will get them at 70 to 75% fan setting
I have never seen an s-7 get past freq 800 so good luck at doing better then that
this over clocking voids warranty
Thanks man , How can i check the voltage? cheap meter below should work. http://www.amazon.com/dp/B0012VWR20what is your psu? |

I have a question. Why 5ND? I like it cause I keep getting paid even when I have to stop mining, but why not 2,3 or 4? Just curious. Thanks Edit- Also has it always been 5ND from the start? Will the number change based on future pool size? I'm done now  I don't like (and I guess most don't like?) mining and getting rewarded nothing for it  5Nd means it takes a > 500% block for that to happen. CDF: 0.99326205300091 500.000% 1 in 148.4
So back when I changed it, 148 blocks was quite a while, so was rare. The 'unfair' way I changed to 500% at the time was to the advantage of the people who didn't leave the pool when I changed it. Making it higher means the 'abstract ramp' takes longer. Again back when I changed it, the ramp was longer. The number itself simply reduces the reward variance. The bigger it is, the lower the variance. Too big means it takes too long. 5 seemed a good middle ground. I was wrong I thought it was always 5nd. I would not mind it being 7nd which would be 35 hours or so. right now we are more like 25 hours. |

Antpool was @ 300PH/s around 10 days ago and now they are mining with 342+ PH/s. Those 40+ PH/s are +2.5% of the network... and its only one pool  And there are new ~30PH pools popping up in China all the time, it's scary how fast they toss up farms over there. I'm really hoping the halving makes big farms not cost efficient to run and we start seeing chunks of 30-40PH drop off the network instead of add to it. I see a sharp rise from april 15 to july 15 then the ½ an a big drop. this should be a lot of fun to watch |

Lol, a very illusrative example, I guess I just figured that plugs like this would be designed to be plugged and unplugged repeatedly. I've had the miner for like 2 weeks and didn't run it all the time, so maybe I plugged/unplugged it like 10 times. I would think a device would be expected to be plugged and unplugged 10 times in its lifetime. I guess the cable just wasn't up to snuff, probably the wires are too thin. I just checked and they are only 18 ga., so yea, too thin.
Does anyone have a source for stuff that I can make my own wires? I guess the hardest part to source would be the connector on the psu side since I don't think those are industry standard like pci-e (or is the psu side of the pci-e cable an industry standard?).
I'm going to contact Block C today and hopefully they can facilitate an inspection and any necessary repairs. Of course I would cover the cost if deemed that warranty wouldn't cover it.
sidehack may be able to help with cables |

Cloud mining is very hard to earn a profit.
as to whether you should get an s-7.
1) your power cost?
2) do you own a proper power supply?
3) can you cool the space?
4) do you tolerate the noise it makes?
the new s-7 can be had for 482 if you have the 100 usd coupon.
A power supply is about 150
total cost is 632 + shipping say 700 if you start from scratch .

Yes looks like both sockets have been overheating due to poor contact of the pins. This will have been made worse by the Daily plugging and unplugging. I would look for a way to have the Miner plus permanently connected and an additional plug / socket arrangement for the swapping.
One thing that is strange is that the problem has only occurred on the 3 Gnd connections and not the 12V. This may indicate that the PSU Gnd wires have been made up with a different batch of socket crimps that the 12V ones?
Rich
Yeah think of the unplugging and re plugging as fucking. Thus the name for the plug and jack. As male or female. With repeated fucking most female sockets get loose. The male pins do not suffer as much from repetious fucking just like real life. Crude analogy but easy to remember.  This is the best explanation in technical stuff that I've ever heard Thanks I thought it was pretty good myself  |

If you think about it, eBay will be inundated with S7's beginning in May. That's going to drive the price of them down tremendously. They may go as little as $300 each in May or June on eBay. I honestly think you stand a better chance of making more money buying bitcoin at current price and sell it close to the right time on a potential pump and dump.
Maybe, although we said exactly the same thing for S5s and those who bought them early and just held them made a killing even on moderate power costs. There is also the tertiary market of people with negligible power costs to whom S7s are still valuable and may create an artificial floor in S7 prices. yes this is a good point. I am in that position with the solar array with buysolar. We have 12 -16kwatts of 'free' power and we have 8 avalon 6's and 1 s-7 = 28th at 8.3 kwatts so I could buy 4 s-7s now and just add 18th gets us to 46th at 14kwatts . Then just mine until we get a deal on the newer gear I think I may buy the 4 s-7's in the next day or so. |

Estimated Next Difficulty: 168,533,193,229 (+1.83%)
Adjust time: After 560 Blocks, About 3.8 days
Hashrate(?): 1,215,308,390 GH/s
Looks like the silence before another storm!....
my guess is the storm hits in the april 15 to april 30 jump this jump ends say april 1 say +1% next one after that ends april 15 say -1% but april 15 to april 30 + 5% to + 10% |

if you have 2kwatts per hour 24/7/365 you can run 2 s-7's clocked down to 4000gh esach total of 8000 gh 2 kwatts per hour is 8000 btus of heat and the gear is loud but if you have free the free power of 2 kawtts a day and buy two s-7's my guess is in a year you could 2x the money invested. that is a guess not a certainty. |

Sold 1x Avalon 6 unit tonight, so the free kit that philipma1957 was so kind to offer is taken. I have 3x Avalon 6 units left in New York that are still available.
Again, philipma1957, thank you very much! I did not know about his offer till I had the sale and seen the messages.
HolyScott
No worries I am sure one day you will be selling some gear I need and give me a good deal. I will leave this open more as support and or questions on the older group buys. |

P.S see my numerous post about me trying to get Kano pool to 40PH to help decentralize the network. Only myself and Philip mention that. I actually flexed my muscle to help push it from 33PH to 40PH during that nasty ridiculous week.
Yeah and they all left, they're just hoppers who clearly have no idea of mining statistics. Like most pools, I don't really like hoppers. When they are large, people see the pool hash rate going all over the place and some consider that an issue. I'm way more tolerant of them coz they have no effect on luck and they wont 'hop' in and get extra BTC doing that - none have those magical pixies to tell them when the pool will find blocks Certainly I can say this in hind sight due to the results the Block Statistics show: if you had listened to Philip and just pointed your hash rate here, around 10 weeks, at a total 110% for 10 weeks, is pretty hard to beat ... Big dogs on top are always more visible but smaller people often jump without notice. I've been on 4 months out of the 5. However, I sense there's no appreciation for my hash nor my contribution here so I'll just use it elsewhere. I'm done on Kano. And here you were telling us all that bullshit about how emotion has nothing to do with it, it's just finance ... kano cut him some slack he is young and still gets the fever. There was a time i thought I was smart enough to pick better and had the magic touch. |

based on the last post you should buy some btc and just hold it for 90 days.
if you buy .250 btc it would be about 107 usd
