Well, that all make me think of this Overhash guy: https://bitcointalk.org/index.php?topic=878921.0Thanks Aurel57, i leave it. Just found this thread yesterday, damn that i did not found it 1 Month ago... EDIT: one of the payments of the block was going to a guy or side "OxyWhite" In germany two Days ago a drug dealer was caught who sell on the darknet under the Name OxyWhite. Maybe it is not a kiwi.... Ahh would not this be karma. If I knew our 25 + 10 coin thief was busted after he used the stolen coins to buy the dope it would be worth my small 6 or 7 usd loss here. |

Does anyone know if its possible to change the output voltage on this 2880 psu? What about the bitmains 1600 can you change the output voltage on that PS
I believe there is a write-up about upping the voltage on Bitmain's 1600W somewhere. As far as I know, voltage control is not possible with the 2880W PSU's, however the dual DPS-2000 that J4bberwock has developed and I should be producing this week will have voltage control as an option.
if you open bitmaintech's psu it has an internal pot that cranks up to about 12.6 I just read a review with photos of the pot. The bitmain psu has shitty pcie cables. and cost over 165 shipped to the usa. finksy + j4bberwock can supply 15 gauge beast cables this will help over clock and if you have 2 avalon 6's like I do ite becomes more important since the avalon use only 4 jacks. @ finksy I sent a pm on ordering the 15 gauge cables. j4bberrwock sent me a breakout baord and i have 2 2000 watt psu's from ebay coming. I will need the 15 gauge cables I want to do a series of tests and photos that show how well they work for avalon 6's and I held onto my best s-7 I want to show how the better cables allow higher clocks. |

Today is looking at another 15% day, wonder where all this huge hash power is coming from.
yeah 143 block made in 20 ½ hours means a 160+ day. price support is there so diff will rise. |

I never said it had to seem like the miner had an ROI i asked for the best Gh to Wattage ratio. and the First one posted is currently the best if it runs at that wattage and Mining speed.
so you think a u3 at 1 watt per gh doing 63 gh is 1 watt. the u3 is 1 watt at the wall with a quality psu. with a shitty 80% brick it is 1.25 watts at the wall. you have to buy one from asic puppy and get the custom router + firm ware. It is not much of a bargain. . The truth is your choice to be in the range you pick of 50 to 65 gh kills most picks. |

So an attack is underway? Must I stop mining here forever? Or can people come to terms over S.P.V. ?  |

Order's like that on S7's and Avalon 6's could keep us at these high difficulty's. I hope we lower it some, but I think what I wish and what happens are two different things.
Also price around 395ish most of day so pretty stable. But we just can't break that 400. Once we do I think it will be interesting how fast it goes up.
High price, efficient gear coming out, and cooler temps for a majority of the mining population equate to high difficulties for the whole winter I think. This thing is going to keep climbing 'til the halving, because of the factors mentioned and probably because a lot of people are going to be in a push for the 25btc block reward while it exists. since we have about 435ph older gear and about 135ph newer gear And my .25 watt s-7 at 10 cents is better then a washington state .51watt s-5 at 5 cents more gear will be added as long as price support is there. 395 usd is good for ^ diff |

so, am i allowd to point my stick to the pool from the 11th ongoing? just got a nice usb fan and already thinking about getting a 2nd stick before the 11th  yes the plan is to expand from 40 to 50. members start a new 1 month run. if we get to 50. part a prize of 12 btc / 50 = .24 coins which is about 96 usd it is still the best chance to make money on sticks. I will also continue to toss extra hash which as always helps the 1 or 2 stick guy out. Tonight I am going to start a new thread but it will be locked until the 11th. |

Just received 2 S7 batch 7. What update from 23.10.2015 should i put on them ?
There is not yet a firmware update for Batch 7, so I would stick with what you have got for now. Rich to follow up on firmware updates. bitmaintech firmware updates have not had a great track record over the last 2 years. I never update firmware from them. This is on 12-15 s-1's 15-18 s-3's 3 or 4 s-5's and 5 s-7's I can find at least 20 I bricked my gear posts during a firmware up date. I can not find 20 my gear is great now that I updated the firmware posts. I suggest never update bitmaintech firmware on your gear. Unless your gear is bricked and you posted about it here and contacted bitmaintech. And I suggest the opposite. Always upgrade the firmware after it's been tested. My S5's had an issue of dropping to 600 GH every once in a while and the only way to restore full functionality was to reboot them. I installed the latest firmware and haven't had the issue since. I think there is a middle ground, which is upgrade if there is a good reason to do so, such as the S5 release that kept the fans running when you lost Internet or when fan control was added. Rich That firmware update may be the only one they ever had that truly was worth doing. So I will go back and slightly alter my post. I went back and did the edit. Now so far more then one person has said the s-7 firmware updates do not fix the no internet problem. So frankly I do not recommend doing any firmware up grades on an s-7. I set my fans on manual control (50%) and get them to run at 3600 + 3480 rpm. This fixes the no internet issue. Or at least has done so for me on three occasions I dropped the net. |

Edit: if others have done a firmware update on the exact same piece of gear that you have (ie all boards and same oem firmware) It may be okay to do as some have pointed out the s-5 had a good firmware upgrade. |

I'm a young miner that has been in the bitcoin community since 2011 and was deep into bitcoin back when the original $1000+ jumps were happening and made some money with it.. the problem is i've been away for a while and i'm having trouble finding the best miner (50Gh-100) That's power efficient and not a crazy amount so maybe with altcoins there could be a jump in value. anyone have any suggestions at todays current best power efficient miners? Thanks!
get a s-1 do the pencil mod run it at 140gh and use 180 watts they are cheap will only earn money if btc jumps up a lot or if you hit a block with it. i am selling three of them in the marketplace. but if you are local to new jersey we can do a meet and sell only one |

You can wish all you like but there's absolutely no way to confirm a full node really is a full node and not just faking it. If full nodes were to get paid, then one could spoof as many full nodes as they like and get paid for each of their fake nodes. To prove they're full nodes you'd have to invent some kind of "proof of work" and add it to some kind of blockchain - congratulations you've invented mining and an altcoin blockchain.
so there is no way to prove the full node I run is real? |

300 to 325? they have collected more then 35,000 btc for s-7's which could be 7000 units or about 35 ph

j4bberwock sent me a 2000 x 2 = 4000 watt break out board.
I ordered two psu's on ebay.
I will need cables
18 15 gauge
12 16 gauge

OUCH! That's not very good return rate, was hoping it's around the 1200 watts mark. Do you manually change the voltage settings? I heard people who were using the Dell didn't have to touch anything and can get 3800 on some units. I get free electricity for Saturday so OC is perfect on Saturdays. =)
well my meanwell is not a server psu and can adjust on the fly down to 9.6 volts and up to 13 volts. it is a 1500 watt unit and was picked up un ebay for ⅓ retail price of 350 I paid 125. I wanted a really high power psu for testing under and over clocking basically I have become convinced to use finksy + j4bberwock 4000 watt psu. I have 2 psu's on order http://www.ebay.com/itm/252144440397?https://bitcointalk.org/index.php?topic=1178099.new#newoh what fans should work? |

If you want to easily have the voltage adjust working, ask them if they can ship you revision number lower than S9M. If they can't, you could use some zero ohm resistors to mod according to my pictures a few posts ago. I used pins salvaged from dead DPS2000 PSUs on mine. Those resistors should do the job if the leg diameter isn't too big (looks ok on the picture, and some people used actual cut legs from resistors soldered together to replace the pins): Ebay item 201428019892 Ebay item 121097959648 Just to be safe, I'd put them in some heat shrink tube in case the actual resistor body could touch another pin. If you don't have an hot air station and a solder sucker, you can even carefully drill with a 0.7-0.8mm drill bit in the center of the solder pad that is missing the pin. Total length of the pins is 42mm. I haven't been able to source them from regular sources like digikey/mouser... Will try from my main connectors supplier. they read s7. I have your 2x board on hand I will post assembly > when all pieces come on hand. |

Kilo,
Did you find out how many watts they draw to get the 4000 GH/s rate yet? Trying to see if it's worth it to get these Dell PSU and go for that Hash rate.
my meanwell is 87% efficient and it uses 1400 watts to do 4000gh which is .35 watts per gh. a big fall off from my seasonic doing 950 watts for 3250 gh about .29 watts |
