sir, with great pleasure I watched the pictures
do you accept and appreciate donations for great posts?
Sure. Thanks. |

Holy crap, so awesome. I heard about these on the radio, but really wanted to actually see a picture. So cool that the first one I saw was of an X6500!
Thanks!
Can I post a link to this on fpgamining.com, or even better, embed it?
Yes, of course. Click on the Lytro logo and you'll see a way to embed it. |

balanula, i try to be nice to people on the forums as it is how i want to be treated, but you posts push the limits of my patients. Why are you always trying to find fault and start controversy? Are you unhappy that you didn't buy a single sooner?
He's been that way forever. I just ignore him. Unless you bought them at 25k/ea.
Now that's a good price! Breakeven in 5 months. That's incredible if they can deliver it... it will breakeven before the mining rewards drop to 25btc. Ok folks, I have some good news with regards to the power requirements for the RigBox. According to "People Familiar with the Matter" (TM) - the RigBox will use dual 1500w PSUs, meaning they will be 120v/220v switchable units... also meaning you can plug, (presumably) each PSU into a separate circuit to prevent overloading one circuit with impossible current draw.
That's awesome. Inaba, you should as the people in the know if they've thought about splitting the rigbox into 2 devices then? Sell them for $15,000 each, mining 25.2 Ghash/s for 1250W. That would make more sense, right? Send 2 of these devices to the people that ordered a big rig already. Or would they not be able to achieve those specs then? |

When I run cgminer with 6 GPUs, 3-4 of them end up in the DEAD state after a while. Anyone know why that happens or how I can debug it? Quitting cgminer and restarting it fixes things.

It would be great if the latest boards can run the 200 MHz bitstream without additional cooling needed.

any plans to support the x6500 fpgas?

Taking out just that one added assumption, and the system works again. If my node has block X, and another block comes in (call it Y) that has the hash of block X-1 in it, that new block is rejected. Unless when block Y+1 comes in and has the hash of block Y in it instead of X. When that happens, block X is tossed out, and block Y gets unrejected.
In this case, if block Y+1 meets the acceptance criteria, block Y becomes valid, even though I didn't like it when I first saw it. However, if block Y+1 is also an antisocial block, they both remain on the lonely pile until a good miner builds on top of it, or until the X chain grows longer than the Y chain, making the issue moot.
There may be holes in my idea, but I don't believe that this is one.
Seems like a bad idea. There's going to be a lot of wasted work if half the miners are working on a different block. You will effectively halve the total network hashrate and make it that much easier to 51% the network. Plus if X+1 and Y+1 are found around the same time, it gets worse. This also makes it easier for some to try to double spend their coins. Probably best to keep things as they are and things will sort themselves out as designed. |

Excellent, I'll be going through this!  speaking of power supplies, the one for the rigbox is going to have to be a beast huh? Well speaking of the rigbox, can you even run these at home? If i'm doing the calculations correct, I = 2500W / 110v = 22.72A. Most US home fuses can only support 15A to 20A. So these will not work without doing some electrical work, right? I guess with such a large investment, you'd probably want to run it in a datacenter. |

Basically, they are currently looking for 25 suckers to help them catch bugs, improve designs, perfect layouts BEFORE running off 10,000 potentially sub optimal chips. Then they will sell thousands of these and difficulty will shoot up and these 25 "early investors" will never make back their money. |

I just read the whole 7 pages of this thread and sounds like a complete echo of the BFL thread at the start ( except we have BFL to compare to.)
Except BFL's initial price per performance target was outstanding and even with it's revised specs, it's still very good. LargeCoin's price per performance target is already not competitive. Who's to say they can even produce hardware up to these specs that their simulation showed. |

15k is much more reasonable; also license file non time liked with out remote drm. I like the escrow in fact it's essential; why not 5k up front and then 1k per month with each payment you send a license file until 15k is paid. You could also come up with a formulae on price by incorporating the difficulty ratio at the time.
As others have mentioned with delivery in late July and block rewarding halving in Jan it does not leave much room for a decent payback period if btw does not substantially appreciate in early 2013
I know there is probably endless speculation regarding what will happen to the BTC exchange rate when the block reward is cut in half, but my own opinion is that the halving of the block reward will reduce supply therefore increasing the price - probably by enough to recoup the lost "revenue" from the cut in mining reward. Another consideration is that if the exchange rate fails to increase to recoup the halving of the mining reward, people mining inefficiently will leave the market, and those operating FPGA and ASIC based systems will reap a larger share of the mining rewards -- halved as they may be. When I do these kind of calculations, I try not to take price into consideration by comparing this miner with buying bitcoins. With $30k now, I can buy 6000 bitcoins today at the $5/btc price right now. According to http://www.alloscomp.com/bitcoin/calculator.php at current difficulty (1496978.59503), 20 GHash/s earns you ฿408.51. Let's also assume difficulty stays constant. So from July to December, you will earn ฿2043 (5 * ฿408.51), then mining reward halves and you only make ฿204.25 a month. So it will take an additional 19+ months (19 * ฿204.25) to make back the remaining ฿3957. So at least 24 months to breakeven. If I had ฿6000 bitcoins today, would I use that to buy this miner? ROI is 24 months at the optimistic low end (where difficulty stays constant, 0% pool fees, and free electricity). If difficulty increases 1% a month, ROI increases to 30 months. At 2%, 39 months. At 3%, 64 months. At 4%, you would never make back your initial investment. The answer is an easy no. Warranty is only 90 days, yet you need at least 2 years to make back the money. If the hardware breaks down after a year, you are SOL. |

If you have good credit, we can (as can any business) arrange an equipment lease. But keep in mind this will bind you to a 12 to 48 month lease contract. The problem is that once you start doing contracts for leasing, the cost starts to approach the purchase price, and it may no longer makes sense to lease. The only reason to lease then is so that if the equipment breaks after 6 months, you can break the lease or get new equipment. But then if you do month to month leases, it makes less sense for LargeCoin to lease you the equipment when they can make more money just mining themselves with it. |

ttyl, thanks for clearing this up. If you reduce the price to $15k, you will find demand for your product. But at $30k, it's way too expensive.

No, there's no remote kill, and the phone home function is optional and for your convenience only. Our ASICs have a crypto mechanism that checks a license file that you must supply to the system. The license file specifies how much mining the system will do, in accordance with whatever license you've purchased. For the C200 units we are taking orders for currently, the license will be unlimited.
Do I have to provide the license file each time the miner boots up or is it unlock once and the miner is plug and play from then on? |

Yes, the hosted solution is quite ridiculous. Who's to know if the miner is actually the one producing the hashes? I'm not trying to accuse you of anything, but for all I know, the miner is pretending to do something and using up 100w and you have a GPU farm sending my pool hashes. And you only have to do that for 90 days.
