What are you doing with your dead blades?
Perform black magic rituals with them? I dunno to be honest, probably nothing other than just keep them. I plan to bring it to some electronics repair shop in the lucky chance that it's just a blown capacitor or something repairable. If it's a burnt chip or something similar to the stories I've heard in the avalon tech support thread then I would have no clue how that can be repaired. I thought the Avalon architecture allowed for a dead chip? |

Dogie, this is super helpful. Thanks for posting.
Wondering if you have some tips on using BFGminer to mine on Bitminter? I have my cube up and running but not getting 38gh in overclock mode.
I've specifically avoided mentioning BFGminer because there is no advantage over the much, much, much simpler stratum proxy method - it just adds confusion to those who really need the barebones approach. I'll probably add .bat scripting info to point to other pools tomorrow. This unit is 36.7 so thats pretty close. Looking at the chip numbers, my first board underperforms the others by probably 700MH. |

Great guide as always just wondering I blew 2x 650W on overclock tonight, each cube had 650w PSU, I could smell almost like burning plastic for a while but I thought it was just the new cubes but came home tonight and found both cubes had turned off and PSU's totally not turning back on.
They were decent Cool Master PSU's with 25A
Just wondering why they blew.
Also can you suggest a good PSU that could be used for many cubes ? Is it possible to use the Sata to 6 Pin adapters ?
Thanks
Can you link me to the exact PSU? Seems strange that they would be rated at 650W when only able to provide 300W on 12V rails. Anything Corsair, you'll pay 10% more but get a big warranty and know exactly what you're getting. The 800W one I recommended is exactly what you'll need to run two off one PSU. You can't use sata to 6 pin adapters, SATA connectors are only rated for 25-35W. If you mean molex to 6 pin adapters then I'd still say no unless you use a dual molex to 6 pin adapter. A molex could cope with 75W 24/7 - not 150W. |

Great setup guide Dogie. Thanks for the great write up.
No problem. If there is any particular hardware you want sorting then let me know. Currently got an antminer here which I'll do tomorrow. |

I think its fine as it is. If there was no need for non custom hardware talk, why are there still 100s of posts in there? We don't want non-custom in custom so why force them into here.

Dogie's Miner Setup Guides:Nicely formatted version available at dogiecoin.com!  Contents: 0a) What type of blade do I have?0b) What You Need1) Powering2) Cooling3) Case4) Configuration5) Troubleshooting6) Where to buy0a) What type of blade do I have? (top)There are 4 current types of blades in the wild: | V1s batch 1 | - No overclockable firmware and only 10 were sold into the wild. Made up of 1x hashing, 1x power delivery and 1x ethernet boards. | | V1.batch.2-3.5s | - All other blades sold at auction. Have overclockable firmware. | | V2 | - Now one single board, includes a backpane connector and is slightly smaller. No more overclocking as the necessary hardware is removed. | | V3 Cube | - A great consumer product with no more wiring, cooling or mounting complications. |
The ASICMiner Cube contains 6 mini blades that hash at ~5.4GH each, mounted on a single motherboard.      0b) What You Need (top)You will need the following: 1) Powering (top)Cubes do not come with a power supply, and you will need a typical computer PSU with: - 2xPCI-E 6 pin power connectors
- At least 28A on the/each 12V rail
- No load protection. When cubes are turned on they exhibit an immediate burst of high draw, which some larger PSUs identifies as an overload
Estimated power consumption is as follows: - ~200W (no overclock)
- ~280W (overclock)
I would recommend the following PSUs: For 1 cube:
(Click.your.flag) |        | For 2 cubes:
(Click.your.flag) | |
We also need to tell the PSU to always be on, as there isn't a motherboard to do this. Cut a paper clip into a U and insert it into the green wire and either black wire to the side of the green wire. Tape it up for safety. The power supply will now be controlled by its switch on the rear socket. Remember to plug the fuse in [green disk], either way round will do.    2) Cooling (top)Each cube comes with 1x120mm RPM controlled fan which remains quiet at all temperatures. Should the fan fail, the unit will stop hash and so is prevented against overheating. It is recommended to reverse the fan's direction in order to increase cooling performance (and hash rate). You'll have to unscrew the end plate with the fan and the 4 silver screws attaching the fan to the end plate to do this.     3) Case (top)The case on the cube is a single extruded tube with two end pieces, held together with 8 screws. Cubes are stackable side to side and top to bottom. Dimensions are 135.5 x 152.5 x 147.5mm (5.33" x 6.00" x 5.81").   4) Configuration (top)- Power on as above.
- Plug in a network cable from the cube to your router. USB is for debugging only and serves no function for us.
- Change your router's subnet to 1, ie 192.168.1.x. This is just temporary. If this is not possible, see below indented steps.
- Plug in a network cable from the Cube to your computer.
- Disable Wifi if applicable.
- Navigate to Control Panel -> Network and Sharing Centre -> Change Adapter Settings
- Right click on your ethernet adapter -> Properties
- Click on "Internet Protocol Version 4" and click properties
- Select "Use the following IP address" and enter the following:
- IP Address: 192.168.1.1, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.254
- Resume normal steps.
- Using a browser, navigate to 192.168.1.254:8000 - this goes to the cube's configuration page.
- Change the IP to something memorable like .200. If you have multiple cubes, connect them one by one and change to .200, .201 etc as you go. If you
don't you'll have conflicting IPs. You can also change your subnet back now if you want to. - Cubes use the extinct getwork protocol and so we need to use a stratum proxy. Download the proxy and open the file.
- On the cube config page, enter the server address the IP of the computer with the stratum proxy on. Enter it twice as the cube needs two pools to start
mining, ie "192.168.1.102,192.168.1.102". If you are unsure what IP your computer is at, open cmd and type "ipcongif /all". - Username and password is for Slush's pool, stick with that for now. Again enter it twice, user:password,user:password.
- Click update, then navigate back to the IP of the cube you set using a browser.
- Set clock to high by hitting change clocks.
If you want to change pool, create a .bat file in notepad (save as .bat). Move the stratum proxy to the location below and put the following text inside for your choice of pool. Change pool port and address for different pools. Antpool Register!cd C:\Program Files (x86)\Proxy
mining_proxy.exe -o stratum.antpool.com -p 3333 cd C:\Program Files (x86)\Proxy
mining_proxy.exe -o stratum.btcguild.com -p 3333 cd C:\Program Files (x86)\Proxy
mining_proxy.exe -o us1.ghash.io -p 3333 Configuration should look like this:  5) Troubleshooting (top)| Problem | Solution | | "x" in a row on "Chips". | - There are just a few faulty chips - nothing we can do. | | Almost all "x" on "Chips". | - A mini hashing board inside is faulty or lose. Open up the case and take a look. | | There is a rattling sound inside. | - Likely some of the screws have come lose (common), open up the case and take a look. | | My.Cube.mines.for.a.bit,.but.then.stops.until.reset. | - Take all android phones/tablets OFF the wifi, they interfere for some reason. | | I can't achieve turbo mode | - Try using two PCI-E connectors from different cable strands. Turbo mode isn't guaranteed so its part luck. | | My cables are braided or aren't color coded. | - See below diagram for pin-outs.
 | I still can't get it to work  | - Post a screenshot with your cube's configuration page, cmd with ipconfig /all and your stratum proxy. |

Ive updated the OP to include V2 blades, let me know what you think. Edit: Also created a new thread for cubes. Anyone who needs support for them please head over there as they are very different [in a good way]. https://bitcointalk.org/index.php?topic=352658 |

These power cables are only intended to carry 75w each, while 8 pin connectors can carry 150w each.
This is PCIe spec, not molex. Well, each 6 pin has 3x 18 gauge awg 12v + ins, which should hold 10 or 11 amps each in theory. That means a max wattage of 360 - 400w each, but you get pretty close to the max at 600w load. If the psu cheaps out and uses 20 or 22 gauge awg you will probably run into problems. Like you say according to the AWGs they should be able to hold more - but those AWGs allow wire temps up to 80C or something rediculous. That's why 6 pin PCI-Es are rated at 75W [should really be ~150W] and 8 pin at 150W [should really be ~250-300W]. From the ASICMiner blades, I can tell you tough that plenty of things that say they are 18AWG clearly aren't and burn pretty quick. |

The pictures made it look expensive. And the OP mentioned the coolant being expensive. Numbers would be more persuasive though. In any case, the heat is still expensive to make, and long-term, competitive mining operations will have to make good use of the heat they produce. Versatility will be a strong advantage here, and scaling up would appear to diminish from this.
They look expensive, but remember this is mostly passive. All we have here is helfty shelving, aquariums full of expensive coolant [which isnt consumed], piping and then a few high flow heat exchangers [read NOT AC - so only power costs of fluid flow]. You couldn't design this to be comparatively cheaper if you tried, |

Anyone have any thoughts on what the 20nm will produce?
3TH 12.3BTC at the current price for Q1/Q2 2014 Q1/Q2 as a shipping date is a bad joke.. What does it means, that they could ship in January or in June? That's a 6 months time-frame. They should say in which month they ARE going to ship. And then be off of their estimate by a single week and subject themselves to irate customers? They are just giving themselves a good cushion in case there are problems which are very likely to occur. And remember this is KNC... they under-promise and over-deliver. *Over delivering late isn't over delivering. Its 'not getting sued'ivering. |

Unjacketed 2 pair wiring for the ethernet connections - space saving, I guess?
Also may prevent wicking of the Novec...
I wonder about the shielded plugs, though. With no ground connection / shielding along the cable, the shielded plug does nothing, and I'd think they'd be more expensive.
10 MB Ethernet (what blades have) can run on Cat3 if my memory serves me right. Cat3 setup is cheap and requires no shielding other than what twisted pairs already have. Jacketed wires will be nothing but a pipe for liquid to get into... shielded RJ45 jacks were either cheap(er) to get than plastic ones at that time or maybe they have something to do with heat exchange? 37 degrees is pretty hot for a plastic RJ45 connector (non-stop) I would think, but I'm really just guessing the purpose of the metal plug. 37 degrees wouldn't matter too much as there is no thermal cycling, no real mechanical loads or anything to deform/take advantage of the impaired strength. |

So much for a "decentralized" coin.
I appreciate the technical work, but images like these challenge my confidence in Bitcoin.
To me it just illustrated bitcoin mining's diminishing returns to scale. I doubt this kind of operation will be viable long-term. Heat is a waste product for these guys that's clearly expensive to dispose of. But for small home mining operations, that heat can be put to good use heating the air and water. Distributed mining also distributes financial risk. These kinds of operations strike me as fat that the industry will trim as it matures. They've proven its NOT expensive to remove though. With capital investment and advanced tech, they can almost passively remove a 'shit tonne' of heat and achieve infinite density. |

Thanks for the update CH, maybe if you let us know what admin rubbish you'd like taking off your hands, someone can help you out for a while.

do people on this forum not read other people's comments?!!?
or does it not matter to them that this equipment is likely stolen? I guess the correct statement here is: "Proof or stfu". edit: was meant to be tongue-in-cheek  Alberto is the person behind the Labcoin Scam that stole more than 7000 BTCs (along with Alessia and Fabrizio Tatti). Many leads did confirm that. The location of this equipment is Iglesias Carbonia, 20km from Barbusi (Alberto hometown). As soon as it was reveal that the miner might belong to Alberto (ie labcoin shareholders), the listing was ended. Draw your own conclusions as all this, of course, might just be circumstantial The thing going for the credibility is that someone clever enough to get that hardware in the first place wouldn't be stupid enough to try and dump it all at once, mere miles from the crime site. Or, if someone is stupid enough to get that hardware.... |

Anyone interested in an open-air case for ASICminer blades?
Each blade is secured to the tray via a custom plastic bracket. The beam that the brackets and fans are attached to could be mounted on the opposite side.
Any comments/suggestions?
p.s. Does anyone have an accurate drawing of the backplane mounting holes?
3x120mm won't be able to remove 800W of heat, those blades will be way too hot. I've had something similar in this config, it doesn't work with 120mms. |

All we know is shorter than conventional hardware. We're using effectively early engineering sample quality designs.
Most likely a random component on the PCB will die before the chip itself though, due to bad product choice, non-optimal design or overclocking.
