I don't care if Avalon were to run a third batch for themselves IF they are considerate enough to not attempt a 51% attack. While not ideal, they could mass produce a significant chunk of the network hash rate using the fixed cost resources that miners paid for. I haven't done the math but it seems logical that Avalon should manufacture and host enough hash power to cover their internal non-component costs(salary, rent, etc) and continue to use miners to fund lithography shrinks and future products. Continuously funnel a portion of the new products to their private farm to maintain a constant percentage of the network but not enough to raise any suspicions. It is for the best that I'm not in Avalon's position. I'd be ruthlessly exploiting the greed of miners to line my pockets  |

Even Jeff and BTC Foundation may receive functioning Avalon, think twice before you order the 2nd batch: 南瓜这次发货的方法我很熟悉
我见过有人这么做，做出来的产品良品率低，就从矮子里面找高个的
拼凑出来几台最稳定的机器先拿出去
我和群里的也说过，我相信他发给JEFF的那个机器是工作的很完美的机器
一旦JEFF发了评测，后面的人哪怕拿到的是垃圾也只会认为自己比较倒霉
Translation: I know the way how NGZ is shipping his product.
I knew someone shipped his product like this before: Since most of the products were defective, he picked the best ones and built a few stable machine for first round shipping.
I told other people in the channel: I believe he will send a perfect machine to Jeff. When Jeff has released his report, other customers will just think they are unlucky even they receive a crappy machine.
The hashing chips have yield problems (depending on the optimization of the density even 50% of chips can be bad). If You assemble a board with bad chips the whole board is bad (unless the board is designed for redundancy). On the other hand testing each chip separately is very expensive and time consuming (without special equipment that allows on wafer testing). The only proof for the batch1 machines to be functional is a 50% increase of the hashing power. I would imagine that the company that did the packaging of the chips would also be running a functionality test. I believe that was mentioned a while back. |

There is very little in the way of moderation done on this forum. Why start now? Or rather, why moderate just one topic instead of the entire forum or select sub-forums? I am not one for restricting conversation but the amount of non-constructive drivel that is posted makes this website for the most part useless. I'm not sure if Bitcoin attracts trolls or if the lack of repercussions permits them to flourish but something needs to change for this website to be a useful platform for discussion.
I propose make more sub-forums like the mining speculation forum and have no rules there. Heavily moderate the forums where actual facts are discussed. If the trolls want, they can go troll speculation sub-forums without burying facts in their crap.

I'm curious if Washington has low enough summer ambient temperatures such that you could filter outside air for particulates and use it as your cold-air. It looks like Seattle averages highs in the 70s during the summer. Drop your average electricity costs at the risk of having to throttle back during June and July. Would be a neat solution.

I already explained that 75A at 1.1V is well within tolerances. At stock voltage and 1100MHz, GPUz says my 7970 VDDC current is between 150-160A.
Well compared to a 5970 powered by an single rail 850w drawing about 50A, wouldn't mine drawing 75A be sucking more power from the wall resulting in a increased power bill? Dude please read what he has been telling you, he was pretty clear. Your PSU offers 12V power to your GPU. Internally your GPU transforms the voltage and feeds it to various components that would likely explode at 12V or some such. PSUs offer 3 voltages depending on the line, 12V, 5V and 3.3V, that's it. 5970s require PCI-E connectors, which are 12V (or in your case Molex to PCI-E, which is still 12V). If your card were using 75A of 12V power, it would melt, and your Mobo would melt, basically your computer would be dead. Again, look at your GPU-Z, look at VDDC, and VDDC Current, they should say something like 1.0V, 75A. As the first response said, Watts = Volts x Amps; or 75A * 1.0V = 75W. I suggest you buy a kill-a-watts meter if this is still bothering you, to confirm you don't have some freak GPU pulling 900W. Also maybe google the terms, amperage, voltage, and watts, to get a clearer sense of how they relate. This should be clear enough to the OP. If that isn't enough, I'm running 3 rigs with 3 watercooled 5970s @ stock core clocks, 1.0vddc and 500 MHz on the memory. I'm seeing around 700w pulled from the wall per rig for the three cards, fans, pumps, mobo, cpu, etc. You most definitely are not pulling 75 amps of +12vdc from your 5970. If that were the case you wouldn't have a 5970, you'd have a puddle of slag  |

Curious what you plan on using for the facility. Are you going to negotiate for seriously discounted colo rates or repurpose a non-datacenter structure and kit it out to host from?
There's a ton of stuff needed to house, cool, secure, and manage racks of gear and it isn't cheap. I understand that you are just putting out a feeler for demand but I wonder if you have a plan yet or will formulate that plan if demand is high enough.

Well that went smoother than expected. Looks like I'll be skipping mtgox from now on and using this service.

Exploding? It appears to be growing at 0.5% per day give or take a bit. That's pretty typical for the last couple of months.

Ok, seems I was right, revenue per block stays the same or better it seems?! So that must mean about half of miners stopped?! It's increasing block by block so happy days for FPGA!
This is so weird, must mean all miners on deepbit use FPGA or keep GPU going?!
But block speed should be half and its been ~3 hours and 28 blocks mined so that doesent make sense? Can somebody please explain whats going on?
Random variance. Block 210041 was ~39 minutes long. |

At $0.11 USD/kWh and it being winter in Colorado I am still mining away on GPUs. My apartment stays at a comfortable temperature and with current difficulty and rewards I'm still making a few hundred dollars above electricity costs. Something interesting.. Litecoin/BTC pricing doesn't appear to have budged. According to http://www.litecoinpool.org/calc if I were mining litecoins right now I'd earn roughly the same BTC as I was earning prior to the reward split. |

Yeah, that 100K ASIC chips is Huge! That's double the number they initially told us and if they all get released in the next 6 months that's basically Half the profit and double the time for ROI people initially speculated. Not too mention at $1300 per Single it's over 2X the price of an FPGA Single when released. We may end up making less per ASIC Single than had been making the last 6+ Months per FPGA Single. IMO this doesn't bode well for future earnings when put together w/ todays reward halving. I hope i'm wrong, but it may be the ASIC companys who make all the $$ in the end.   A few people will make a lot of money. The majority of people will barely break even. The company selling the shovels ASICs will profit greatly. Just another gold rush, nothing to see here folks. This is of course if we actually see an ASIC hit the market. |

Good news for my GPUs I suppose. Would be most helpful to have one of these companies release a product so I can stop sitting on the fence waiting.

I found after a physical move I had to readjust all my overclocking settings. Not sure why but the settings which used to be stable no longer are. I find the less I disturb the rig itself and the less downtime it has, the more stable it is. Starting it up again after downtime is the most precarious time of all and when I've had hardware failures as well.
Same. I had a rig that ran for just over 2 months with no issues. I rebooted the host rig and on reboot I had 7 of 8 GPU cores. That 8th core never came back regardless of how much crap I tried. I think I've had 4 5970s die this way. I'm down to 12 5970s and I'm determined to only shut them down when I plan on permanently shutting down. |

Agreed. Single 5870 pulls around 150w-200w at stock while mining.

... or simply for those who cannot get a credit card or PayPal account because of a poor credit rating. Seriously there are close to 30% of adults in the United States who do not have a credit card. Ever wonder what happens to your plastic when your home is lost to foreclosure?
By the way one can receive income from AdSense and not have a credit card because of poor credit.
I don't have a credit card. I do however have a debit card through my bank that works just as well. Need to setup a credit card though just for the credit rating benefits. Just never needed one  Agreed on the adsense bit. I used to have Google mail me checks when I ran an adsense generating site. |

if this is the main reason why the little rally is going now that reason is stupid so stupid above normal levels
you don't get it.... why i should pay with bitcoins if my ad revenue comes in USD from google care to explain me that If you are already receiving ad revenue from Google then chances are you already have a way(Paypal) to pay for Wordpress.com services. This is more important for individuals who live in countries where they don't have that accessibility. Sure, it might be a few hoops to find a local BTC seller, purchase your BTC with fiat and then purchase your Wordpress services but clearly Wordpress saw some market for this. |

At this point I am waiting on the sidelines. BFL turned me off with their lack of information and bASIC failed to release any information when they stated they would. I've sold off most of the GPUs and am just running enough GPUs and FPGAs to heat the apartment for this winter.
I'll wait to see the fallout of the ASIC releases and perhaps pick up some miners from whichever company has the best offer. In the meantime I'll keep checking my btc balance and crossing my fingers that the price increases a bit in the next few months. Daddy wants another car.

Just a bump for this PSU. I own three and they're about as good as it gets. The only downside is the PCIe connectors of which there are 7 instead of 8 which requires using a molex -> PCIe adapter for quad-SLI/CF. I've beat the hell out of these running stupidly clocked(1200+ MHz) GTX 580s and they just keep on trucking. Closest thing to a bulletproof PSU that I've used.

It consumes ~9 megawatts to achieve its performance record. That's a bit of a bill to pay.

Any chance of decreasing the operating speed and core voltage to boost GH/w efficiency? I fear if BFL delivers on their 1 GH/w efficiency and nobody is close then they will be the only choice for those with a multiple year outlook on using these devices.
