http://usawatchdog.com/jp-morgans-frauds-are-epicunprecedented-in-world-history-william-black/CEO Jamie Dimon has presided over the largest financial crime spree in world history. . . . It depends on how you count it, but it is more than a dozen, and more in the range of 15 major felonies that either the United States investigators have found, state investigators have found or foreign governments have found.” The Professor goes on to say, “JP Morgan’s frauds are epic in scale, unprecedented in world history. . . in these $23 billion we’re talking about, these are frauds that made Jamie Dimon and other senior officers incredibly wealthy by creating fictional income that led to very real bonuses.” Bill Black is a well known law and economics Prof. at UMKC.

Question to MBP about volume discount for H-card
a) Are there any upcoming discount for V1 H-cards? The price at the EU store is E 250 (~$338) without any discounts.
b) Will you re-instate volume discounts for H-cards?
Thanks

did you add the following to your run_cgminer.bat? setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1 You didn't mention the amount of system RAM. |

Any price drops on the 400+ GH/s models or introduction of higher GH/s setups (basically an addon master card/board)?
I see they are selling them quite good and overpriced of course. When people are buying them is there any reason prices to be dropped? The answer is...... I still don't understand why people are paying for overpriced miners to fund bitfury's private farm (currently at 200TH). Remember people: for every miner sold, bitfury adds a couple more to his farm so think twice before ordering. Stupid stupid people. Because it's an ASIC miner that ships today. And do you honestly think that Bitfury doesn't currently have enough funds to support it's own private farm without the few pennies that we add to their coffers? Lol. Who's stupid now? Everything has a reason dude... Just think about it I hope you're not responding to me. I just received a 1/2 rig, 1/4 rig and 3 V1 H boards last week. I happen to think Bitfury and BitMain gear are very reasonably priced at the moment. An even lower price would be better but I'm not waiting around for that to happen. I think those who are always complaining about over-priced gear will never be happy enough to make a purchase. That's why the ASIC vendors just ignore their pleas. Why try to satisfy a potential customer who will never actually buy your product, right? +1. when the price drop happened, it was enough for me to justify a small purchase. however, they need to come down another 20% before I go out and buy full rigs. alternatively, they fix the rPi SD-corrupting issues and ill buy  its a massive pissoff that i am scared to reboot the unit or otherwise touch it at all when in operation, even if i think a few more GH/s could be had Have you tried an UHS-1 card? I've had great luck with toshiba 16gb UHS1 card. I no longer shutdown -h now with those cards. That is no long term fix. Why would you not properly shut down? Think about what not shutting down properly does to a regular hard drive. There is nearly constant writes happening to the sd card. Not properly shutting down is asking for trouble, which will come eventually even with overpriced fancy pants class 10 sd cards. a) I solder my own H-cards (4 chips at a time) and it's a PITA to `shutdown -h' now to test a new h-card after soldering 4 more chips b) I live in a brownout prone area. c) UHS-1 cards have a far higher write speed, and unless there's a lot of pending writes when the power went out, the fs is automatically fixed by fsck on the next reboot. With higher write speeds, the chances that the card gets caught with a pending write gets lowered, and my hunch is that it becomes negligibly low with UHS-1 cards. In my experience a really slow class-4 card craps out in 3 - 4 minutes (since the /run/shm/.stat.log is updated a lot at the beginning), no matter how careful I am with doing a clean shutdown. It's got something to do with the nature of ext-3 fs. d) I agree it's not a good fix, but its one that's been working fine for me since last 2 months or so. take it for what it is or leave it. |

I have a few quick question regarding string configuration.
Q1 ) Can I assume each bitfury chip acts like a diode, and a string is just a series connection of multiple chips?
Q2 ) Do the chips have an internal voltage regulator or some kind of impedance adjustment?
Thanks in advance.

Do you put an 'X' of thermal paste on the back of heatsink, with glue at the four corners? I'd like to do this, but I'm finding conflicting advice online on how much paste to use, and how to apply it. A small dab behind each chip, and superglue in between. |

Goxed -
What do you use for thermal paste and glue? I would like to try this but I have never used either.
Recommend a supplier? I am sure a bunch of places carry it, but curious.
I have a link to the ebay supplier in my posting. each heatsink comes with 2cc thermal paste . You can try arctic silver or antec diamond if you need more. I used superglue as the adhesive between thermal paste |

how is that handling compared to the individual VGA heatsinks you were using? any increase in overclocking headroom, or is 38-40GH still the practical maximum?
it does not help a lot with speed esp. if the card is running at 35GH/s+, but it will pull up a 30GH/s card with a few overheated chips. Increases reliability and hopefully longevity. |

@goxed what do you mean 55nm is on it's way out? Is bitfury changing something?
I meant that 28nm products are going to be commonplace in the next few months. Most 28nm dies are huge, and thus board manufacturers sell them with factory heatsinks, watercooling, etc. I donot know if Bitfury has plans to roll out 28nm chips of their excellent product. |

Just wanted to let everyone know, I have been invited to review the DualMiner. Will get back to the forum when the item is received.
Thanks

Just a heads up.I have had tremendous luck with UHS-1 SD cards. No amount of power outages, or random shutdown have lead to Filesystem failure yet (2 months and counting). I am specifically using 16GB Toshiba UHS1. http://www.ebay.com/itm/like/261215529897?lpid=82 Thanks I'm guessing those red boards at the back are temp probes, no? Those are voltage regulators. I ordered the PCBs and hand soldered the bitfury chips and slapped on the regulator boards. I was soldering and then testing the boards 4 chips at a time, to root out any dead boards before it created a problem, and did not have the patience to undergo the shutdown routine and instead turned off the PSU switch. The SD-card survived all the attempts. |
