One of my BlueFurys died in less than a week. I have some of the very first Block Erupters still mining away. It's a crap-shoot, really.

One of my miners has died. On close inspection, it looks like the chip was installed with a bucket of solder and a 100W soldering iron.
How to I get a replacement?

-S bigpic:all on BFG 3.4.0 or later.
You didn't do a very good job of searching, there's plenty of threads about this. And there's the README.ASIC which comes with bfgminer. Hell, even Google results show it.

What do i have to write in the textbox below?
My Eligius - 2013-11-14 18:32:48 UTC - NMC_Address=xxxxxxxxxxxxxxxxxxxxxxxxx ?
You copy and paste everything in the first box on Eligius to your "Sign Message" in Bitcoin-Qt. Press the "Sign Message" button, then copy and paste the string of characters in to the second box on Eligius. If it works you'll see "Options changed successfully!" or something similar half way down the screen. |

Stats stuck again? Been mining for about 10 minutes and it's still showing 0.00kH/s.  |

OK, just run tests. Miners were running for 5 minutes - the one I tested was running at 2.5GH. Temp on top of the BitFury chip: 95C  Temp at middle of heat sink: 89C  That's burning hot - probably a safety issue. The Block Erupter in the same hub was running at 69C, again probably a safety issue, but not warm enough to almost boil water. |

Perhaps you should check blockchain.info again....  Perhaps you should also change your topic title to: "I'm impatient and don't mind posting crap on bitcointalk" |

Thanks we will take that into consideration for the next batch. It is my understanding that the heatsinks where sourced at a rush because we didn't want to delay shipping any further.
I just remembered I have a temp probe. Would you like me to measure the temps and report back? I could do that later on this evening if you'd like. I don't have the equipment to accurately measure temperature, sorry. Read what I said again... I'm offering to report temps to you. So you can see what temps real world units are reaching when overclocking using the bent piece of foil heat sink. |

For PSU, I'm thinking something like the Corsair CX750 will be ideal if you're running 2x Cubes. They have decent thick cables, and two pairs of 6-pin plugs. They also don't mind running at heavy load at 12v only - other older supplies freak if they're asked to supply 12v with no load on the 5v/3.3v lines.
I run 2x Blades and several 12v supplied USB hubs, 5x fans, and an OpenWRT router (soon to be replaced by a RPi) off my CX750, and it's been perfect for months. The CX750 replaces a Zalman 1000W unit that couldn't run 1x Blade because of the lack of load on the 5v line.

Blah, feel free to feel the way you feel about what I post. In all honesty, I couldn't care less. It's not helping anyone either, but I hope you got your daily portion of "let's be negative at random forum people"
You're better off trying to help all the people who are not getting what they've paid for.
I think if you read my posts, you'll find a LOT of my posts are indeed help. Either directly to other users, or with developers in bug reports. Only a small proportion are 'STFU dumbass' posts. Those posts are reserved for a select few, FYI. |

Change the resistor and put a decent heat sink on.
The one supplied with my two units are pathetic, and even with a fan rammed up against them, they're running at holyomgshithot temps at 2.4GH. The ones on the RedFurys looks like they could cope, but the heat sink on my Blue Fury is more like something I'd put on a 7805.

At least you're getting something. My 7GH Jalapeno was ordered in late June. They're shipping early April orders. Expensive paperweight by the time it arrives (though if BTC keeps going up in price it might still be worth running if/when it arrives).

So is it working?  |

OK, got 3.6.0 on. Had to do it manually, rather than via LuCI. Still showing 100% errors. Edit: Did you get around the hidapi thing then? Luke-Jr, any ideas? Still no-go here. |

So...did you miss the "Group Buys" forum, or are you just stupid?

Sadly enough I'm starting to feel the bluefury isn't a good product.
That's your opinion. You obviously don't remember the clusterfuck the Block Erupters were when they came out. It's sold as 2.2-2.7ghs but many people don't even get above 2ghs. Besides that it seems many miners are bad products, only mining half speed or lower, and the amount of HW errors on all devices is just so high.
People have to do pencil mod tricks to get some decent speeds. (and I'd like to add, please remove those posts from this thread, pencil-modding a device has nothing to do with support)
The pencil mods should stay. Just because you don't like it, doesn't mean it should be removed from the thread. This is a support thread. Where people go to learn about the product they paid for. Also I see many questions and little answers.
I see more complaining and crying, especially from you. Hoping there will be something like new drivers or firmware that will fix this, but slowly I feel it was a bad buy, especially considering the price we paid.
Opinions are like arse-holes. Everyone has one, and most of them stink. |

some news?  I had a massive dump this morning. It was spectacular. In other news, the train was late this morning, so the level crossing was down, delaying my entry to work by 2 minutes. There you go, two never-before-heard pieces of news, hot from the press. |

what should I check next?
How to upgrade to a recent version? Good one Helldiver But I just when back to 3.1.4 because that was the only one that worked I have 3.5.1 installed Now they all just hang when I start them. Have you tried clearing out your .conf file? Any time BFG craps out like that on me, it's something broken in the bfgminer.conf... me too... back up and remove that .conf I removed it yesterday, deleted everything on this computer and restalled everything about 2 hours ago and it still doing the same thing. I did everything that I could think of also read through most of the thread bitcointalk. Where is bfgminer? If it's somewhere in your user folder, it may be a permissions issue. Copy the bfgminer folder to the root of c: and see if that helps. That did not work either! Any other conflict you can think on that I can try would be greatly appreaciated I all out of ideas, sorry. |
