Unfortunately TH is very sluggish in this - I tried to make a deal with btceic and another member with no success...
If KnC succeeds along with Bitfury and maybe AMC and/or labcoin, I don't think I will look again back at TH...
That's why customers need variety of choices - then totally unacceptable and unproffesional behaviors like these are harshly punished!
fyi all, I received my full refund today with no dispute by terrahash, (they never replied to the claim) and as previously stated will now stfu about it, which I am sure many of you will be happy about. klee, I appreciate you trying to work with terrahash on this issue with me. I wish you all the best of luck. I am extremely happy for this. I also got my refund today via a Paypal claim - no response or help from TH I will stick around though if only to annoy you and your whiney posts, you are the biggest whiner in here! |

Any word on the ETA of the Avalon chips? to TH or anyone else waiting on them? I know someone had posted pics of a butt load of cases/chips shipping or arriving somewhere...not sure if they were the same chips though...ok,,,,just wondering  |

Another maybe silly question here... when using the Ic2 cables to daisy chain the k16 boards, and with that, only one usb cable with the first board in chain, will only one miner be needed to control all the boards that are daisy chained?? (I'm thinking that's correct) and if so, how would one know if a board should fail in the that daisy chain, and would it stop the boards from working beyond that failed board...ok lots here to ask or discuss And" can k16 and k64's be daisy chained together in the same fashion?  Thx |

To clear up a lot of discussion here about PCIe connectors and splitters etc. Regardless of what the PCIe standards indicate a power cable and connector does not "provide wattage" - they merely transport current as used by your device. What matters is how hot the cable and assembly get for a certain amount of current flowing through them.
Molex rates their connectors according to a certain rise in temperature that they consider safe. The PCIe standards take this rating and downgrade it to be conservative given that many suppliers use lighter gauge wire that will heat up and melt more quickly.
If you use decent 18 ga. wire as rated by Molex, and their connectors, then it is reasonable to use the rated current per pin within a safety factor. As long as the PSU can supply the power, the cables don't somehow limit or prevent power from being used. They simply heat up when too much power is drawn, and consume a small amount depending on their resistance.
So the standard 45558-0003 PCIe connector is rated at 8A per contact, and 3 contacts are being used for 12V to the board, putting a connector based limit of 24A, or 288W. Limits placed lower than that are based on wire gauge and more conservative safety factors but do not mean a cable cannot handle the current. They simply heat up more than if they carry less current. Splitters are fine if they use adequate gauge wire for each leg of the split. Stay away from light gauge wires no matter what the standard dictate - light gauge = higher resistance = more power loss to heat in the cables.
18ga. is what the Molex connectors are rated for but they can be used with as thin as 24ga. according to their docs. It's possible to buy pins that go 22 -26 ga. And some Chinese cable assemblies probably use cheap copy connectors. Choose accordingly.

Thanks for that info BKK. Very helpful. Gives us a good idea as to what quality of wire we should look for in the splitters for our multiple k16 board units. I was always under the impression that PCIe power cables could handle at least 150W a piece. It's nice to know that a high quality PSU(cables, etc) can put out more through each cable. I think I'll keep it at 4 cards per cable to be safe. |

Everything is looking fantastic!  Is there a thread to monitor bulk Avalon chip distribution? |

BKK Thank you for giving us a better understanding on the molex/pci e connectors, and the significance of the gauge wire to use...very helpful! Maybe a little guidance on the daisy chain woes if any, would be useful...even though it seems pretty straight forward. and chaining k64 and k16 together? |

Interesting, so who's chips are shown in that pic? as far as TH orders, it would be hard to say if their order would follow suit time wise" but does make ya wonder...lol |

Based on all those pictures that have been posted of tons of Avalon chips at the warehouse, I would think (hope?) that they are going to be filling a lot of backorders in very short order. I don't think it would necessarily follow that orders place 1 month apart would be filled 1 month apart. |

3 questions for Amir / Terrahash:
1) A normal PSU does not have 10 or 20 connectors with 6 pin so ... Does DX Mini case come with adapters for 20 modules even if I ordered only 10 ? If yes, I assume this adapters are available even if I ordered the case without PSU.
2) Similar question about cooling system and fans ... I assume DX Mini case will have full cooling for 20 modules regardless of number of modules ordered in the case ...
3) How many USB cables I need to use to connect a DX Mini with 10 boards to a computer ? Do I need 1 (from DX Mini to computer) or 10 (for each module) ? I hope only one ...
My concern is about a possible upgrade (buy more modules) and I wand to understand if I need anything else other than plug in the module itself. Do I need any extra cable or adapter or anything else ...
Terrahash, based on your message I assume the answer to my 3rd question is 1 USB cable to PC ... I2C jumper cable (provided by Terrahash) is used as connection between K16 boards. The I2C connector is 4 pins. There are 4 connectors on each board. 2 on both sides of the USB connector and 2 on the edges right next to the edge with the USB connector. The 3 Pin connector is for the fan. TerraHash boards will each come with a I2C jumper cable to daisy chain the board with another one. Please, can you please comment on my first 2 questions ? Terrahash, Do you have any update on the DX Mini case ? We are still waiting to see at least some drawing / rendering if not real picture of the case. Thanks, Jake |

PM me if your interested. Just cancel your order. You should never have placed it if you didn't plan on mining with it. All you are doing is allowing people to skip line who were too stupid or lazy or unprepared to get in line with everyone else. |
