"There are no bids yet for this product."  I guess everybody learned their lesson? lol Let the chips die on the vine. That is the right response. There are still people hurting from Avalon... lost investment, seeking refunds and so and so on. Auctions to me reek of desperation. Why not a store with a set price and shipping? Why the extra layer of complexity? its already set at 30BTC in the store - they just dont realise the chips are only worth about $1-$5 each for a reel, not $10+ |

... I'm measuring 600w to the power supply with a rig running at this rate. PLEASE use two seperate PCIe power cables to power your rig. Check cables for warmth - lets be safe folks! Be careful trying to plug too many rigs into a single power circuit - 15 amps on a 15 amp breaker is NOT ok  The cards are very strong and so far very consistent. There are still some EOL's and a few noisy cards too. I really hope you are all really happy with these hot rigs! Cheers, Dave Okay so i bought a 460W PSU as the mbp website STILL recommends to do so. https://megabigpower.com/shop/index.php?route=product/product&product_id=53 (was purchased at the end of September before this announcement was made) Can I simply buy a 2nd 400W psu and have both sets of pcie cables connect into this miner or is that not recommended? At this point I would rather pay 15 dollars more for a 2nd psu than to shell out 60 or more for the sake of being able to utilize one plug outlet and one PSU. not recommended. if you need to shut down the system, powering off 2 psus simultaneously can present issues, especially if 1 unit backfeeds into the other. Your 460w psu is too weak, and almost certianly does not provide the full 460w on the 12v line alone. (probably 60w or more on 5v and 5-15w on the 3v) at 400GH, the unit can run on about 350w (approx), but the units shipping are effectively optimized more so that they will do 600GH. |

28 nm as well
Well, I hope that KNC has room for improvement on their first pass at 28nm. I'd really be interested to see what Bitfury can do at 28nm since they are already more efficient at 55nm than KNC is at 28nm. And I think that Bitfury still has some improvements they can make to get the specs of their 55nm die closer to the projected 5GH/s per chip that they were aiming for. They may even be able to go to a less costly die process like 32nm and still kick everyone's ass. I love that guy. I used to love him too, but not anymore because of his high prices. in a few days all the october pre-orders will be fulfiled, and i expect a drop to reasonable prices ($12 per chip and $300-350 per h-card) |

Will there be a price drop on h-cards? These are looking mighty overpriced given the current difficulty.
soon i hope - Ive been shopping around for canadian-built/assembled boards and am looking at $50-$120 per 8-chip board or $75-$150 per 16-chip board not counting the cost of the bitfury chips (which should be $10 each to be properly competitive at this point) USD 300 is a good price for 16chip H-boards starting difficulty 500MM. The Jan chips are selling for $5 a pop if buying at full-reel prices. https://megabigpower.com/shop/index.php?route=product/product&path=33&product_id=64$5 each in January may not be cheap enough. For a 16-chip board you would be looking at $150 ($80 for chips + $70 for board/assembly) |

Except for KNC, it seems like all of the other ASIC vendors are having difficulty bringing their 28nm designs to market. I'm starting to think some of the millions of preorder dollars and bitcoins are in possible danger of never being returned if the designs ultimately fail.
And it doesn't help confidence levels when the ASIC vendors stop communicating their progress and future plans!
So what's your guess on who will be the next bASIC? Or do you think everyone will at least deliver some kind of working miner to investors whether it meets planned specs or not?
cointerra has been quiet lately it seems (but i dont actively follow them) but they were not planned to launch until 2014 |

My new-ish rig.  2 280x cards running 750kh/s each. Lots of fan noise  why are you pointing fans at a water-cooled system? that seems almost entirely pointless, the heat exchange radiator for the watercooling loop is the only thing that should require much airflow |

If anyone want to take a tracking of his Bitfury based on performance data of each card, here you find a macro for Excel which track all JSON-data each 5min. It delivers you some results as table and chart. You can analyze as you want, e.g. by card, bus, slot, SPIerr or MISOerr. Just open in excel, enter IPadress and click start. Ciao Enrico im getting debug errors through this whole chunk of code: Workbooks(sFile).Worksheets("Config").Unprotect "bitcoin" Workbooks(sFile).Worksheets("Config").Cells(2, 2).Value = "logging stopped" Workbooks(sFile).Worksheets("Config").Cells(2, 2).Font.Bold = False Workbooks(sFile).Worksheets("Config").Cells(2, 2).Font.Color = RGB(0, 0, 0) Workbooks(sFile).Worksheets("Config").Protect "bitcoin" and the similar chunk below for "logging started" ... "Bold = True" ... etc am i missing something, or is there an underlying macro or feature i need to instigate? |

And this is what i get...:

Voltage still 0.3V
I measured resistors,
R01F: 2,120K ohm
R02F: 2,120K ohm
..so Ti chipis broken...?
1) switch to autotuning. clearly setting manual tuning to 54 across every chips is working terribly based on your 15-30% error rates. 2) R02F is quite high at 2.12K(ohm). try using the pencil mod to reduce it to 1.85K(ohm) and see what happens. If lucky, this is the issue and youll see the voltage rise to >0.6V. If it does, maybe the wrong resistor was placed and you should see if it can be changed for something in the 1.65-1.8K range 1. As you can see, m-board don't even detect BANK1 h-card(s). It is autotune mode now, but no help.. 2. If I do pencil mod that, that will broke h-card warrantly...? pencil modding is techincally messing with the warranty, but a tiny marking of pencil lead is not very hard to clean off and, unless you seriously manage to do it wrong, shouldnt cause anything worse then putting a bit too much voltage that in turn turns off the chips until you restart the miner (after dabbing away a fraction of the graphite with a fingertip) try pulling out and re-inserting the board. i had a board dissapear the other day (after almost a week in place) and pulled it out, checked the connector and reinserted it. works fine again. I think if there is vibration from fans or weight from heatsinks it may be possible it simply isnt seated perfectly with all the connectors making contact. |

A better test would be to power the card and measure voltage at the top of the Pulse inductor. If you get ~0.75v there (or whatever it's adjusted to), the power circuit (including that capacitor) is probably fine. I only say "probably" because I just fixed a board that was missing a cap on the back side. Before replacing that tiny back-side cap, the voltage at the Pulse top was correct, but the card wouldn't hash stably.
okay, i measured, it was 0.3V or 0V, what i can do next? okay, lets start at the top: 1) you are forcing tuning to run at 55 when you use "aIfDSo 55". the fact you are seeing more than 10% errors means you should not have them higher than 53 or 54. change them to auto-tuning. (AIfDSo) 2) a few chips (such as 52) are set as "aifdso". this wont work in the bitfury system unless you were forcing custom timing clocks and other info to the chip (you aren't). change them to AIfDSo. 3) where are 1-30? 4) Your chips are producing way to many errors. half of their hash rate is actually errors. You need to cool your chips better. The chips currently at zero likely switched off because the autotuning was overwhelmed by the high error rate. you need to have good cooling fans, and likely add some heatsinks. 5) if you havent yet, update your chainminer following the method mentioned several times in this thread. do the above and then check again. it should resolve 90% of your hashrate issues. as for the 0.3V you are measuring, try again after the changes. if its still <0.6V, check the values of the resistors R01F and R02F. in a board with capacitors these should be 1.0 and 1.25 k(ohm) respectively. In a board without capacitors they should be -?- and 1.7k(ohm) respectively (i dont know the R01F value for the board, but its likely not 1.0k like the first version) if your resistors are not these values, thats the issue. if they are correct, then its onto the next step. probably the small TI chip found right beside them (it has about 12 or 14 pins) that is responsible for bringing 12v->0.7v Wait... are you saying that for chips that don't work/generate too many errors, setting them as aifdso doesn't work?? if not, what additional information needs to be provided to actually turn them off?? I can see a bunch of zero's in that line, which that seems to indicate they are technically switched off, so I don't understand why you're saying that aifdso alone doesn't fix the problem.... Thx for clarifying... i meant for all the chips that are working, you have seriously high error rates with your manual tuning. autotuning will work a lot better. |

would these work with less than 16 chips - say 10 chips? if so i imagine specifiic positions only and perhaps a jumper might be needed if they function like a chain..?

okay, i measured, it was 0.3V or 0V, what i can do next? problem card,A1, not detected 31 aIfDSo 55 1.241 2.199 50 23 0 0 120 [8:E] 708 3 4 2 1 2 2 4 5 4 $ 32 aIfDSo 55 1.639 2.236 66 37 0 0 122 [8:F] 693 2 3 4 7 2 4 6 4 3 $ 33 aIfDSo 55 0.670 0.495 27 0 0 0 27 [C:0] 730 2 2 2 2 1 1 1 1 1 $ 34 aIfDSo 55 1.763 2.401 71 28 0 0 131 [C:1] 687 2 2 5 5 3 3 4 6 4 $ 35 aIfDSo 55 0.000 0.037 0 0 0 0 2 [C:2] 756 0 0 0 0 0 0 0 0 0 $ 36 aIfDSo 55 0.000 0.000 0 0 0 0 0 [C:3] 756 0 0 0 0 0 0 0 0 0 $ 37 aIfDSo 55 0.000 0.000 0 0 0 0 0 [C:4] 756 0 0 0 0 0 0 0 0 0 $ 38 aIfDSo 55 0.794 1.741 32 23 0 0 95 [C:5] 724 2 2 1 3 2 1 1 2 3 $ 39 aIfDSo 55 1.440 2.566 58 36 0 0 140 [C:6] 699 4 3 3 3 4 6 6 5 2 $ 40 aIfDSo 55 1.514 2.419 61 38 0 0 132 [C:7] 697 3 5 5 4 3 4 5 1 5 $ 41 aIfDSo 55 0.869 2.511 35 48 0 0 137 [C:8] 721 1 0 2 2 1 3 1 3 4 $ 42 aifdso 55 0.000 0.000 0 0 0 0 0 [C:9] 756 0 0 0 0 0 0 0 0 0 $ 43 aIfDSo 55 1.663 2.383 67 40 0 0 130 [C:A] 693 5 6 3 3 5 2 5 6 4 $ 44 aIfDSo 55 1.738 2.456 70 34 0 0 134 [C:B] 689 5 3 4 3 3 4 5 3 7 $ 45 aIfDSo 55 1.266 2.438 51 28 0 0 133 [C:C] 706 3 3 5 3 4 3 2 2 3 $ 46 aIfDSo 55 1.763 2.364 71 16 0 0 129 [C:D] 687 5 4 4 4 5 5 5 4 3 $ 47 aIfDSo 55 1.936 2.511 78 27 0 0 137 [C:E] 680 5 5 5 5 4 7 5 5 5 $ 48 aIfDSo 55 1.589 2.364 64 20 0 0 129 [C:F] 693 4 5 4 5 5 4 4 4 2 $ 49 aIfDSo 55 0.000 0.000 0 0 0 0 0 [D:0] 756 0 0 0 0 0 0 0 0 0 $ 50 aIfDSo 55 0.000 0.000 0 0 0 0 0 [D:1] 756 0 0 0 0 0 0 0 0 0 $ 51 aIfDSo 55 0.000 0.000 0 0 0 0 0 [D:2] 756 0 0 0 0 0 0 0 0 0 $ 52 aifdso 55 0.000 0.000 0 0 0 0 0 [D:3] 756 0 0 0 0 0 0 0 0 0 $ ... speed:5092 noncerate[GH/s]:53.973 (0.574/chip) hashrate[GH/s]:85.449 good:2174 errors:1078 spi-errors:1 miso-error$ 4: 832 19.787 29.564 797 361 1 4 8: 880 17.180 29.198 692 379 0 0 C: 880 17.006 26.687 685 338 0 0 D: 880 0.000 0.000 0 0 0 0 E: 864 0.000 0.000 0 0 0 0 F: 756 0.000 0.000 0 0 0 0 okay, lets start at the top: 1) you are forcing tuning to run at 55 when you use "aIfDSo 55". the fact you are seeing more than 10% errors means you should not have them higher than 53 or 54. change them to auto-tuning. (AIfDSo) 2) a few chips (such as 52) are set as "aifdso". this wont work in the bitfury system unless you were forcing custom timing clocks and other info to the chip (you aren't). change them to AIfDSo. 3) where are 1-30? 4) Your chips are producing way to many errors. half of their hash rate is actually errors. You need to cool your chips better. The chips currently at zero likely switched off because the autotuning was overwhelmed by the high error rate. you need to have good cooling fans, and likely add some heatsinks. 5) if you havent yet, update your chainminer following the method mentioned several times in this thread. do the above and then check again. it should resolve 90% of your hashrate issues. as for the 0.3V you are measuring, try again after the changes. if its still <0.6V, check the values of the resistors R01F and R02F. in a board with capacitors these should be 1.0 and 1.25 k(ohm) respectively. In a board without capacitors they should be -?- and 1.7k(ohm) respectively (i dont know the R01F value for the board, but its likely not 1.0k like the first version) if your resistors are not these values, thats the issue. if they are correct, then its onto the next step. probably the small TI chip found right beside them (it has about 12 or 14 pins) that is responsible for bringing 12v->0.7v |

Wouldn't the iphone be worth more than 4x $60 bitfury chips? I mean, we're talking about an elaborate heist for a couple hundred bucks... if that's the plan, why not go for more? Doesn't add up.
more like 4x $20 chips If they were lost after you arrived in the US, it is possible the TSA might have randomly searched the luggage and taken the chips because they couldn't figure out what they were. Usually they leave a notice in the suitcase when they do this kind of thing, but not always.
Sounds very probable. If the lock was not "TSA Compatible" they would likely cut it without hesitation. This. Is it that strange to think that customs would cut your lock yto check the bags (they do this dozens or hundreds of times a day) and either the chips slipped out (they are small) or were simply seized because of an arbitrary rule (seeing unidentifiable computer chips is a red flag IMO) I think its safe to say your chips were not STOLEN, as though some creeper decided your bag was worth breaking into at the airport, and stealing <$100 worth of chips that have no use without a dozen other components and a PCB |

Another question: What means if one chip shows aifdso 240? Like the first one  And it seems that autotune is not working, on the screenshot I manually worked with 2,5,12 chips. The first one is setted up to AIfDSo 55 but automatically falls down to aifdso 240. The second chip was turned off by me because of very low hashrate (200Mhs). Can you tell something about the first chip? And maybe you know what should I do for 2,5,12 chips to increase their hashrate? Thank you! ps: overclocking to 0.95v and oil cooling change nothing... change the first to either autotune 'A' and/or change the value to 53. it shouldnt be 240 and is probably caused by a mis-match the last time the file was modified (mine showed 545 once but worked once returned to a usable number). check your spacing turn chip 2 on. use autotune or start at 53. tune chips 5 and 12 to either 53 or autotune. 50 is too low and may be your issue. finally, im surprised you could get 0.95v even with liquid cooling - pretty impressive. scale back to 0.90-0.92v as its a safer level and watch your autotune. ideally your chips should be 53-55 (most of mine run 54 when my system is stable near its cooling capacity) |

Have one in hand, ebay buyer never purchased. 625$ paypaled and I will ship it free of charge. Just want to get rid of the damn thing. It has never been used.
US ONLY.
good luck getting more than $400 - i'd offer $350 but am in canada |

Next, insert best card to 1 slot in each bank. Board with the worst performance in the last slots. Wasn't this done right before shipping the unit? The cards have A1, A2, etc. written on them. Furthermore, I received mixed revisions, i.e. cards with and without caps. The cards with caps are always in the 4th slot of each bus. Is it safe to move them to the 1st/2nd/3rd slot or will they (or the capacitors on them...) blow up? they wont blow up but most accounts indicate that they work best at the last slot of each bank. how are you ooling the unit? heatsinks or at least strong airflow is needed for 16 cards. it looks like your chips are making errors then switching off. this is typically related to heat |

you can do more than 40Gh/s with by disable few chips or disable dead chips for OC.
what? Are you implying that disabling chips will make the board faster? |

Nice results, goxed. What voltage are your boards at (once they're heated)?
The boards with good chips are at 0.9V, the ones with >=2 bad chips are at 0.95V impressive. I cant get past 0.88v (39-41GH per board) without having chips or boards drop to 0 hashrate or produce massive3 error rates time to time are you using heatsinks? especially on the regulator and the lower half of the board? I have put up a reference picture in this thread. if you copy that you should get the board up to 0.9v provided there's good airflow. I have good heatsinks but perhaps could use slightly larger ones on the regulator/inductor. 0.865-0.87 is good for 40GH on my boards, but the pencil mod ramps up to maximum (or minimum?) resistance over a few days and its difficult to get the exact balance. once it climbs to >0.88v the boards become unstable and i see high error rates followed by entire boards or just some of the chips dropping to 0 every few hours and upkeep is a PITA. i'm sure if i had cold air moving through the heatsinks (rather then the 21 C room temperature) I could reach 0.9V though, or at least achieve a stable 0.88v If you have 40GH/s stable I think you are at the limit already. Kudos! thats what i figured. Right now its running around 0.86-0.65v and producing 76-79GH fairly stable |
