haploid23, all i can say is that I'm truly sorry about my snarky remark  I recognize now who the scammer is. and i'm offering you my help in the only way i can. Too bad that I can't solve completely your situation, but I can help you to maybe save the next person from falling into such crap. Do good, and you will feel good. It's impossible to save them all, because many, just like you did, jump on the bargains, only having seconds thoughts after thinking about it more clearly, but most times it's too late. May this also be a lesson for those who like to impulse buy stuff... After all, more can happen than just you ending up buying something you don't need or like.  Once again, i'm sorry about my comment, haploid23 no need to apologize, everything has already been said and done, it won't undo all of these scams... but thank you anyways for the apology. i believe this is the biggest scam on this forum, involving at least 8 victims to the same guy. i'll be sending you a PM in a few minutes on all his info i know to be posted on your website. but i think all that information is already on this thread. what surprises me is that even after i posted this thread and spammed his new sale thread to NOT buy his stuff, people still bought his stuff and even the same 6990s that i had already paid for and later wanted out. i didn't even get the supposed refund for the 6990s yet, and 1 or 2 people still paid for them We need someone to organize a list of escrow services. We a list of where you can leave feedback/ratings. A guide on how to avoid getting scammed. It should be a sticky in the marketplace. The existing threads aren't very good, hard to search and don't help much to be honest. If someone wants to get organized, get a master list together, pull together all the tips/tricks (checking his paypal email, his ebay, his bitcoin-otc.com profile). The avoid 99% of paypal scams thread has lots of good tips. I'd kick in a .5 btc bounty for whoever can pull it off. You can probably replace 3 of the sticky threads with one good one. If someone selling items has no ebay, no bitcoin-otc, no history, use escrow. The problem now is we need people leaving feedback, ratings, on these sites so people can build up a transparent history. Posting john314 + rocks on the whitelist thread isn't going to get seen by anyone. Food for thought. =) |

Hi, as per title it's either 3G or 56k - 3G would need reverse SSH and 56k might be too slow.
I don't know how much data transfer 8GH would do.
Thanks a mill.
Data transfer is very limited. Latency on the 3g might suck but I'm not sure I'd pay for a phone line. Why not get another broadband connection? Most places have $20-$30 plans which would be perfect as a failover. Because it is not adviable to run desaster scenarios over the same cables. Also my problem with the 56k solution - someone hits the phone box of the street with a car, and both, modem and dsl are offline. 3g would not be. In a building, all phone lines will run to the same station over similar cablings -> no desaster. 2 DSL only sae from DSL side issues. Get one cable broadband and one DSL broadband. It's Bitcoin mining. If it goes down when you have two broadband connections from two different companies for 3-4 hours, that's called letting your rigs cool down before you fire them up for another 6 weeks straight. |

I love the fact you're retarded. But for like $40 you could run it at home without the risk of fire, getting fired, or prison time if the fire kills someone. Tough call.  |

Just one case with all of the extra fans currently installed in it.
Sorry for the confusion!
Makes sense, thanks for the info. =) |

So if a network of comparable size to that of bitcoin miners instead devoted itself to generating addresses, they could feasibly get ~1 trillion/sec. This would get a collision in ~38,000 years. Not bad, but a lot sooner that the obscenely huge numbers posted in the thread.
So far the technology seemed to have been able to double available computation power every 18 to 24 months, how would that reduce the time for getting a collision?  A random collision is useless. Take that 38,000 years, make it 38,000,000,000,000,000 years. CPU power doubling, ehh I still think we're safe...for now. =) |

Every news story about bitcoins seems to say that people can use it to buy illegal stuff. The more correct ones reveal that anyone can look at the exact history of transactions and trace them all, just not back to people in the real world so easily.
So let me ask...if those morons buying fake and stolen prescriptions and rare illegal dog breeds and stolen art and russian brides and crooked roulette tables and crap get busted by police, all the evidence they need is to boot up their computer and look at their bitcoin app, right? I know you can easily view someone's list of receiving addresses but what about sending? Or is that the same thing? Cuz it sounds to me like that kinda takes care of the problem. Catch someone on a minor offense and go poking around or have an FBI bulletin of addresses to watch out for and give it to all the computer repairers in the world with a reward to report them if found. That'll bust so many people, most of the illegal evil doers will leave the system.
It's extremely hard to convince a jury that an IP address means it was you at the computer doing it. When you're trying to prove a crime, saying it was from "XX.XX.XX.XX" IP doesn't really mean it was you. Now let's convince a jury that an IP is you, and that you sent Bitcoins. Have fun explaining Bitcoins to the jury. Unless you're a major drug dealer, you're moving $100,000s through bitcoin, no one gives a shit. The amount of trouble, money, it would take to charge someone with the main evidence being IP addresses and "bitcoins" is the equivalent of burning money and they'd probably still lose the case. Big deal you bought 20 ecstasy pills from some dude in Poland. The DEA could bust raves every weekend and grab people for that shit. And it's way easier to prove then IP address + bitcoins = you to a noob jury. |

tl;dr summary: Bitcoin mining will not collapse for the market exit barriers, thus people will not have to wait for blocks for longer than usual and won't quit Bitcoin altogether.
Exactly. 90% of miners leaving would take 3-30 days to go from 11,000 ghash down to 1,500 ghahs. During that time they'd be at least one adjustment, and we'd be close to another. Blocks solved every 30 mins doesn't destroy bitcoins. MtGox the biggest exchange was hacked, $10,000s of dollars stolen, gmail accounts stolen, it was hardly a blip. The network goes on. Bitcoin will run quite happily at 1,000 ghash. Which means everyone in this mining sub-forum, isn't really needed. We're here to make money for ourselves we could really care less about the network. And the network could care less about us. |

It's crazy the amount of people who just have no grasp on Bitcoins.
The core of bitcoins isn't about "miners" making "profits". It's a currency.
If BTC was $2 or it's $20, it doesn't change anything. Someone selling a $10 item sells it for 5 BTC or .5 BTC. The buyer and seller don't care what BTC are worth. The buyer buys BTC, then buys the item. The seller sells his BTC. It's the same regardless of the price.
People run 5-10-20 folding at home rigs FOR FREE. Actually, they PAY to run folding at home rigs. They buy hardware, pay for power, and get nothing in return. If BTC was at $2 it would make more money then folding. People would still do it. If 80% of the miners left it wouldn't mean a thing long term for BTC.
BTC is about people USING it as a currency, not as a way to pay your rent. The people who power Bitcoins are the people buying them, using them, selling goods/services for them. Difficulty adjusts, transactions get processed, if its 2000 Ghashes or 20,000 Ghashes it really doesn't matter. The miners who think they are the people who make the Bitcoin world go round are fooling themselves. All of deepbit could fuck off right now and no one would notice. All of Slush, Deepbit, BTC could fuck off right now and no one would notice after 3-4 weeks. That's 80% of the network, CYA!
Difficulty drops to 400,000, old miners who left probably jump back in, new people join up, people will do it for free, correction people will PAY to mine BTC at $2.
In fact, the miners trying to make quick money are doing more harm to BTC then good. They dump their BTC as quick as they mine them trying to recover costs. They post on the forum that the sky is falling everytime MtGox drops $2. You think the guy sending money to MtGox, buying coins, using coins to buy something, really cares if it's $10 or $20. Everyone uses the usd/euro/etc.. equivalent anyway. If you look at the marketplace no one is selling for XXX BTC firm. It's $$$ at whatever the going rate is for BTC. There's even auto updated APIs that will match a $20 item to the current value of BTCs.
Go check out the "post your hash rate thread". You'll notice the majority of them are under 200mhash. There are lots of people hashing away at 10mhash. The whole "mining" business is about 800 guys trying to make some money and 25,000 people doing it for fun. Trust me the 25,000 small time miners don't need those 800 hardcore guys. Like I said, those 800 guys are probably causing more drama then they're worth.
Yes, there will always be a group of miners who would mine at loss, and if 80% of the miners suddenly left, the difficulty would eventually adjust. However, there would be a 10 week period, where only about 1 block would be solved per hour. While it would not be the end of Bitcoin, I think we can all agree that it's not a desirable situation. Also, I think you are significantly underestimating the number of people who are mining just for profits, who would quit mining the very minute it becomes unprofitable, but I suppose your guess is as good as mine. No one really knows. Wrong. People run server farms and get paid nothing right now. People will mine BTC because it's fun. People lose money to run folding. People will keep mining regardless of the BTC value. If we went from 10,000 ghash to 2,000 ghash over 2 weeks, sure block time would go to 30-60 minutes. Within 2-3 weeks difficult adjusts and no one would miss that 8000 ghash AT ALL. Would have no effect. Bitcoin runs just as smoothly at 500 ghash as it would at 50,000 ghash. Bitcoin doesn't need professional miners. Period. Again, bitcoin doesn't need professional miners doing it for money. Bitcoin ran fine when the network had a total of 1ghash of power. The network doesn't need 10,000 ghash. People who are mining think the network needs 10,000 ghash. Like I said, 80% leave blocks would slow down for 2-4-6-8 weeks then everything returns to normal. The hardcore miners are doing it for their own personal gain, the network doesn't need them and will happily go on after they've left. |

Glad I bought 5 of them when I did.... getting a solid 310-315 per card.
at what settings? 300 should be easy to get. I wouldn't worry about getting over 300. The amount of overclock, the increased power draw, increased heat, isn't worth it. It looks cool when you tell other people but squeezing out the last 10-20 mhash cost you money. At 930/320 you'll hit 300 easily. |

New patch is working awesome. Running two rigs, 4x58xx and 3x6950s for last 12 hours.

Have you ever owned a 6950 or 6970? The reference board is garbage. There's a reason every single manufacture went with a completely different cooling design. Also most of the reference boards don't pipe it out the back, they pipe it out the side which still goes right into your case.
All of this is wrong. I own four 6970's, all reference cards. In fact I have a hard time finding non-reference card version of the 6970's The ref card design defiently does not dump heat out the side. All of them blow %80-%90 of the exhaust air out the back, and the rest out a small vent on the top of the card. There is no such thing as "most of the reference boards", they are either reference design, or they are not. If they are reference design they have one blower and vent out the back. Of the few modified cooling systems I've seen, most are complete junk. They dump far too much heat into the case. Of the eleven versions of the 6970 currently on newegg only two are non-reference designs, and both of those still vent out the back. Errr no. Go put your finger behind the card, then next to the side vent. The MAJORITY of the air is coming out the side vent. There are threads all over the internet about people talking about covering that vent in order to actually force the air out the back. The ref cards are dumping the hot air into the case. That's why you have intake and exhaust fans. The ref boards are garbage for cooling and they're loud. |

I'd go for a reference board because they dump hot air outside the case. The other designs just recirculate hot air. Reference boards have a centrifugal/exducer-type fan at the very end of the board.

Also most of the reference boards don't pipe it out the back, they pipe it out the side which still goes right into your case. I bought a few 6950 ref boards and unlocked them, honestly I wish I would have just purchased non-ref 6970s. They produce so much heat, the design is awful, avoid reference cards as a rule of thumb unless there's some unlocking that makes it worth the trouble. Having a sealed case where air is pumped through the case sounds good, but that sealed case also means if you put a fan on it you're just hitting the plastic shell and not cooling it at all. With the more open dual fan design you can at least help cool the heat sink and pipes with more fans. Also the reference fan is freaking loud. Way too loud. I can have 3 5870s running, 1 6950 and the 6950 is 3x as loud by itself. I'll never buy another reference board I don't care if I can unlock it for 20% gains or not. They're hot, loud, poorly designed. As for the best, go by the number of reviews and the % of 4-5 stars. If one card has 200 reviews at 70% I prefer that over a card with 10 reviews at 80%. Get a popular card, with good reviews, and you'll be fine. If noise bothers you, read over the cons looking for complaints about noise. Newegg reviews will pretty much tell you what you need to know if you read enough of more. More reviews the more you can trust the ratings. Less reviews a little more risk. |

I am having issues staying above 950mhz. It lasts for 12 hours and then it drops. Does not seem stable for prolong periods of time. Is it possible this is because of my PSU?
I am using a Rosewill 700W (only 72% efficiency though)
I am using a AMD Sempron CPU so nothing else in the rig consumes power.
My temps stay below 62'c on either card so it is not temps.
It depends on who made your card the people saying they get above 1000 mhz I believe all have saphire cards. In my experience the saphire cards can be pushed up to around 1040 on stock voltage 1040? Damn I got a bad batch, err batches. I've never hit 1040 on a stock sapphire (extreme or otherwise). Guess I should do some more testing. =) |

Yeah I meant you just got a faulty card. The failure rate is probably 2-4% for every brand. RMA it and you'll be fine. =) |
|
|

92C is really too high for sustained periods (more than a few minutes at a time). Silicon starts to warp and break down at 90C. Not that it will abruptly stop at that temp, but that's when the MTBF curve starts to really accelerate. The card may be qualified to run that hot but that is just in short bursts, not for hours on end. Even 89 is pushing it in terms of long-term reliability; strive for temps below 80C if you can.
Try to exchange it under warranty, I think you will succeed since you did not modify the card and they should see it as a run-of-the-mill RMA. In theory they could inspect the card and chips and maybe claim it was over-stressed, but that would take a lot of time I doubt they would put that kind of effort in to it since it would be easier just to replace your card.
It may not even be heat related, it may be that you got a card with a bad VRM.
Good luck!
I'm not sure what cards you've used, gpus don't start warping/breaking down at 92C. Sure it's not ideal but 92C won't fry cards. The board was crap, RMA it, it's not a big deal. |

I also get this error but it doesn't seem to effect anything.

that is normal, just the status read routines trying to talk to a phoenix that isn't there (yet). no problem. As for your 4th card issue... the card init routines use the output of "aticonfig --list-adapters" as an index for launching miners. they then look for matching sections in bamt.conf to tell them if/how to start miners, where gpuX is X from the line output from aticonfig. I'm sure it is something easy enough to diagnose and correct, but hard to say when I can't see your system. maybe you can email me the config files and aticonfig output, anything else that might help? aaron@aaronwolfe.comJust sent you an e-mail. Thanks man! |
