Nice tool, but it cannot find one of my cards. I have two 5830s installed, both are being detected by Linux and ATI drivers:04:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 5800 Series (Cypress LE) (prog-if 00 [VGA controller])

Currently hashkill only detects the second card.
I'm assuming you have the device ID hardcoded somewhere?Edit: Sorry, my bad. One of the card is detected by Linux but not by the ATI drivers. This is definitely not hashkill's fault. My apologies. Thanks for the great tool again. |

Thanks, I'll give Windows 7 a try.
I used XP because I have many licenses for it.

I tried both Slush's pool and BTC guild and have the same problem.
If I use the summary or the console it'll say "Connecting..." forever.
After I click "Start mining", in the console it'll display "Listener for "Default" started" and then nothing happens for 5 minutes. 5 minutes later the line "long poll: new block 00000xxxxxxxxxx" will come up, but still no hash rate or GPU usage.
Is this a network problem or a card problem? Should I swap out the cards and try them on different machines?

I'm running three 5830s on a MSI 890FXA-GD70 motherboard. I'm running XP SP3. Two of my machines have this exact same setup and they're experiencing the same error: after clicking "Start mining" in the GUIminer, the lower right hand corner status bar is stuck at "Starting...".
No hash rate, 0 shares accepted forever, and MSI Afterburner is showing 0% GPU usage for that card.
Thanks in advance.

5 cards and up wont work due to a limitation in windows, they simply wont be recognized by the operating system.
Not true. I had 5 cards working under Windows for about 2 days. I don't currently as I rearranged to load balance, but with Dummy Plugs I had no issues. Cable, which cards, mobo and OS were you using? Win 7 Ultimate x64 Gigabyte EP45-UD3P motherboard, all cards run through extender. 2 x16, 3 x1->x16. Ran 1 5970 (Sapphire), 2 5870 (XFX), 1 5830 (Sapphire.) Can you post your speeds per card? That's the only way of verifying whether you have all 5 GPUs working. Someone from this thread confirmed that you cannot mine with more than 4 GPUs: http://forum.bitcoin.org/index.php?topic=19038.0Windows showed 7 GPUs detected for this computer, but that's meaningless, since openCL drivers only support up to 4. |

Another round of difficulty is going up in 9 days, folks!
So? It's supposed to happen every 14 days (though lately it's been earlier than that). That's how bitcoin works. It's not some random event which is designed to piss off miners. It makes the network safer and the blockchain more robust. I think his point was that it's happening 36% sooner than expected. |

No, economies of scale apply.
With current mainstream technologies you can get a hefty competitive advantage by getting industrial rather than residential power rates. In my neck of the woods that cuts the power cost nearly in half (less if you shut down during peak times).
The residential user in some areas can get electric rates lowered if they are willing to intergrate their demands into the power company's smart network so that they can directly reduce demand. For a time, I had a programmable thermostat that would do exactly that. It would be trivial for such an input to control the residential miner as well. That aside, the professional miner is certainly going to dominate, but mining will never be an exclusively professional endeavor. If I use a small miner as a heater in my garage, linked to a thermostat or not, but only during the heating season for my area, the cost of electricity for mining is, at worst, only the difference in the cost between electric resistive heating and the least expensive alternative available in my area. This is exactly why I say that Icelanders are uniquely well suited to owning small, personal mining clusters. Excellent point on the home heating arguments. If I'm not mistaken all resistive heaters have the same efficiency. So ignoring the kinetic energy used to turn your fans for a moment, all electrical energy going into your computer is turned in heat energy. In instead of buying a 1000w heater, you might as well make a 1000w mining rig.  |

Thanks you mrb for the well thought out reply. Remember guys, I said nothing about gpu, just hashing power in general. It could be gpu, FPGA, ASIC, or something only the military has their hands on at the moment. gpu Impossible. There are not enough cards left on the market for this. FPGA Again, impossible, Xilinx and Altera do not have enough stock to fulfill a order this large. Their production lots are large but parts needs to be binned. ASIC 1 million isn't even enough to get the masks designed, let along starting mass production. Even assuming unlimited funds and they somehow kidnapped the all the brightest ASIC designers to work 24/7 on this project, it will still take at least 3 months for the prototypes to start rolling in. At the current rate of difficulty growth (40% every 10 days or so), I'm guessing myself (and most other miners here) would have recouped their costs, made a handsome profit, and quit already. something only the military has their hands on at the moment. I cannot argue against this because there are no evidence to confirm or deny these claims. I personally think that NSA has FPGA farms dedicated to password cracking, but I have zero evidence of this so I do not bring it up in discussions. |

What we see now is two senators discovering something that can be connected to drugs, noticing that no one else tried to turn it into political profit yet; they just grab the opportunity to appear "tough on crime". You answered your own question right there. It takes almost 0 effort for someone high up in the executive branch to kill off the American portion of bitcoin. FBI has jurisdiction on interstate commerce and the Secret Service has jurisdiction on counterfeiting (I am not saying bitcoin is counterfeiting, I'm saying they can successfully sell it to the media as an anti-counterfeiting operation). There are dozen of bureaucrats in DC with this much power, and all they have to do is sent out a memo to their underlings. A simple email. If they succeed, they gain political prestige. Tough on crime, war on drugs, et cetera. If they fail, they can claim it's just part of their job. In the very worst case they are still protected by the Executive privilege. So far, two Senators have cashed in on this free "political profit". I expect many more to follow suit. This is how ugly our democracy has become. There are other senators pushing other issues the think they can get politiccal profit from. Only some of these pet issues will amke it into legislation; we, the Bitcoin community, notice these two senators, since their issue is Bitcoin. All politicions are pushing for or against some issue. I do not see why Bitcoin should be among the few issues that make it into legislation. Then I don't know that much about your democracy. I have seen the call for internet censorship to fight CP in Germany, it became a big political issue, made it into yellow press and legislation, and nevertheless in the end it failed, with the law now revoced. Bitcoin might be in for a similar treatment, but it might take a few years. Philipp I emphasized "executive" twice in my post because I expect only politicians in the Executive branch can damage the bitcoin economy. Politicians in the legislative branch are not a real threat to bitcoin because exactly like you said, legislative issues could take years to become laws and they cannot prosecute people retroactively. That means even in the worst case scenario American bitcoin users could have months to gradually leave the market, thereby minimizing their losses and with no legal precautions to worry about. Politicians in the executive branch, on the other hand, has the ability to freeze Mt Gox's funds within a day and subpeaona the withdrawl records of all American users. Like I said before, this can be branded as "war on drugs" operation, or "anti-money laundering" operation, or "anti-tax evasion" operation. Many law enforcement agencies, such as FBI, Secret Service, and even the IRS has enough authority and manpower to accomplish this. These types of politicians are the ones I'm worried about the most. The victory condition for them is trivially low. They do not a need a successful conviction. They do not need a successful arrest. They do not even need to press any charges against anyone. They only need a subpoena from a Federal judge to crush Mt. Gox's reputation and destroy people's trust in bitcoins. Big media will spin it into "underground currency under investigation by XXXX", then critics of bitcoins will then spin that into "bitcoins declared illegal". Sorry if I sound like a troll, but I'm just voicing my personal fears. If anyone can point out any errors in my arguments then I would love to hear them, since it would make me sleep much better at night. |

At the current rate of difficulty increase you will never break even, even assuming free cooling and electricity.
I dont like the word never here, there are a lot of ways to turn a few btc into even more btc, mining isnt the only way to make btc its just the easiest to let your pc hash away and be afk Since OP never mentioned anything about trading I assumed this thread pertains purely to mining. |

There's some misunderstanding here.
In order to you to mine on a GPU, the following statements must all be true:
1. Your GPU must be detected by your OS
2. Your GPU must be detected by the ATI openCL driver
3. Your GPU must be detected by your miner
The current problem is that ATI's Windows openCL drivers does not work with more than 4 cards. The onus is on you to prove it otherwise. I'm sure many developers would've love to overcome this limitation, but none have succeed so far.
Your screenshot shows that Windows can detect 7 GPUs for the purposes of displaying pictures, but without the help of proprietary drivers Windows cannot do any computation with them. The 4 GPU/OS limitation lies with the proprietary drivers, and not Windows or the miner developers.

So I just got started with Bitcoins the other day, and after mining for a bit with my ancient Nvidia card I tried moving around a little bit of money to see how it all worked. I am using bitcoind on Linux, and have my bitcoin.conf set to paytxfee=0.00, but when I moved 0.01 BTC I was charged a 0.0005 BTC transaction fee! That's 5%! Can some explain this to me and/or how to avoid this? It was my understanding that we could choose to pay no fee if desired and wait longer for confirmation. Edit: Here is the record http://blockexplorer.com/tx/79783b30743aa95de351c3c43e41feae74f0fa7e196a3cab069ab58aa4e51d74Just wait a while after receiving those coins. "Fresh" transactions are considered "unsafe" and thus command a premium. For me personally the transaction fee is waived after about an hour. This is just my personal experience. The "time to be trusted" is dependent on several factors, namely your internet connectivity, the current global hashrate, and the hash rates of nodes closely connected to you. |

5830 is my choice as well, given its overclocking potentials.

It is a good news indeed.
Now decentralized blackmarket exchanges will emerge, protected by TOR and other anonymous networks.
And having legal exchanges like Mt Gox and Britcoin is also very important. I expect it to work like this:
Blackmarket goods <-> Blackmarket exchanges <-> Cash <-> Legal exchanges <-> Legal goods
Well said, sir. I've converted foreign currencies in cash in small local shops and it's quick and easy. It's only a matter of time before they start accepting bitcoin, provided that: 1. the price stabilize 2. there are large and legal major exchanges in every country 3. they're tech savvy |

P.S.: A senator or two giving an interview calling for action doesn't count.
I'm appalled that you think they wouldn't want to and considering the little effort involved in debunking the trollfest on these threads (wonder where it came from) why no one should be careful. Why would "the government" or "the banks" wnt to shut down bitcoin? ...

Hi all,
New miner here. I'm also busy thinking up interesting business ideas to promote bitcoins.
