I have $1500 saved for a used car ...
Uh, so why don't you buy a used car with it, as planned? |

With the power connector on the bottom of the K16 I have to lay the miners I have running on their side. I'm thinking about building a custom shelf for them so I can route power out the bottom. How is everyone else setting up their miners? How are the hosted miners physically configured? And is anyone successfully stacking their miners? Any pictures?
Thanks,
-Jay
The boards appear to have mounting holes to accept a right-angle 6-pin PCIe power connector, but my boards at least came with regular connectors. For mine, I just used extra standoffs to mount the boards far enough apart to stack them and still have room for the power cables to attach. It does make for a tall stack. I may try to replace the connectors someday. |

Tough call. Precise performance numbers may help in deciding.
I'm inclined to take delivery even if they're not fully up to snuff. Some hashpower in the hand is better than none in a pile of parts IMO.

Wow, some amateurs! reused the winning bid on the mini auction and put it on the chip when auction closed without winners..
I don't get it. What bidders? |

PM me the tracking information please.
Thanks.

Wow, thanks. I'll try that out tonight. That should be in Raspbian to begin with IMO. |

I just pushed up updated firmware with 333MHz default clock. It should be more stable at the start, so try that. Then you can use cgm config to clock it higher.
I've got "klondike-options" : "350,50" in my config file and everything works fine under Windows. Averaging about 5.6 gigahashes with no hardware errors and temps hovering around 49-50C. If I change it from 350 to 375 my K16's won't hash. They show up in cgminer, but sit at 0 doing nothing. Any idea what's going on there? I just tried flashing the October 31st firmware from your git, but that didn't seem to change anything. Thanks! Chad I ran into that problem running the git master somewhere between cgminer 3.6.6 and 3.7.0, where no speed other than 350 would work. The bug may have persisted into 3.7.0 (I haven't tested it yet). If I use 3.6.6, I am able to adjust the clockspeed. |

Also, the 60Gh miners on tradehill went for a reasonable price because they were plug in ready to go.
Yah I was on to that one too late. Price for those was reasonable, ready to go and for immediate ship. Did they actually ship them to the "buyers"? |

Status Update:
I received the last batch of boards today .
Almost all of it will be leave my hands again tomorrow.
Was a lot of work to package them all.
Are you talking about completed miner boards? Does that mean that mine are now en route to me? Or do you instead mean blank PCBs that have now left your hands destined for the assembly house? |

I have a stack of their Lancelot clones mining beside me on my desk.

I had been running the git master, somewhere between 3.6.6 and 3.7.0.
I just built 3.7.0, and so far so good. I did still modify driver-klondike.c to increase KLN_KILLWORK_TEMP to 65.5.
BTW, a Pi just does not make a good miner host in my experience. While it works in some cases, it fails badly under any kind of non-moderate CPU load (USB dies, which includes the on-board ethernet). Mine kept failing like that with just 3 K16s attached. I'm guessing the klondike driver hits the CPU hard enough sometimes to cause that kind of failure mode.
I'm currently mining using a Foxconn nt330i with an Atom CPU. Works much better.
Soon I'll have an Odroid-U2 in my hands to try. Should have plenty of power with its quad-core ARM chip.
A BeagleBone Black works OK too, but I don't care for its flavor of linux.

cointerra has been quiet lately it seems
Concur. I see them as being the most likely, followed by HashFast. The idea of 250W TDP in a single die just seems like the wrong approach to me. |

This srsly sucks. I'm glad I don't have anything listed there in auction format at the moment.

I was looking at the CCD-MODULE upgrade to add to my existing order, and when I review the cart it wants to add a separate shipping charge for it. I thought the module would come pre-installed inside the main unit and they would all ship as one unit.
Is the additional shipping charge correct?

just updated my mercury from .98 to .98.1 and HW errors went from 6.9% to around 1.5%. also, rejected was 3% to 0% now!
definitely a good upgrade. all cores functioning as well. none are off.
UPDATE: been running .98.1 for 30 mins now, hw errors down to 1.1% and dropping. still no duplicate shares!
0.98.1 was intended for those with a dead die; die 0 There is no other difference as far as I know. thats what i thought too man, but its made a big difference for me! My Saturn's currently running 0.98 with 1.2% hw errors, and only one core that keeps getting toggled on and off. cgminer reports a long term average of 283.8Ghps. Darned near the theoretical maximum of 284. I'm not gonna touch it. I must have missed something but where did that theorectical max info come from ? I was wondering what that was. Basically, each hash module has 192 cores that hash at 750MH/s each, so 144 GH/s per module. Oops, I mathed wrong. On top of that, I jinxed myself posting that. Shortly after, the unit crashed in some way where it became inaccessible IP-wise. Mercifully, off-then-on-again was all it took to make it happy again. |

Over a month ago. That is good news indeed.  Thanks. |

Well that's just great. :sarcmark: BFL fucks us over again. I still have to ask why you didn't follow up with BFL more aggressively when the delivery first became late. I don't feel like I received the level of customer service I ought to have with this purchase. For contrast, I purchased another lot of these chips from another forum user who had an 18-June order, and they were delivered to me on 11-Oct. Only about 8 days late after accounting for reshipment from him to me. He called BFL right away when they passed the 100 day mark. |

Isn't 50btc.com a mining pool? I didn't know they sold miner preorders. The question seems more like one that 50btc.com themselves should answer.
I'm more interested to know: Has tapeout happened yet?
