I have 7 x 5870s (all different brands) all plugged into one MSI 890-FXA-GD70 with a PCIe x1 extension cables that have been modified by myself to accept x16 sized cards. How in the world are you able to connect 7 x 5870 into that board? I am seeing 6 PCIe slots unless I am looking at the wrong board. Using a PCI -> PCIe adapter also? You're not supposed to see boot infos on anything but the x16 slots I think.
In the BIOS settings of some mainboards you can select to output BIOS video via x16 or x1 or IGP and/or set the order to light them up in. At a shell prompt do a lspci | grep -i vga and see what you see. If you got all of them listed you are getting there. If you don't or are interested in how the kernel is probing the PCI/PCIe busses do a dmesg at a prompt and look for fglrx output. Woops! I meant 6, changed that! Nope, not using a PCI -> PCIe adapter... not really economical. I cannot even get to the shell is the problem. When all of the cards are plugged in via x1 PCIe extension cables... I cannot even get a video signal coming out of any of them. I have tried each one. When they are plugged into the board directly they work fine. Which is why I ask if there is something I am doing wrong or do x1 connections simply not transmit video signals due to lack of bandwidth or something?? |

you may need to do the pci-e x1 bridge trick in order to make cards work at x1.
These are just typical 5870s I am using in this setup, from a few different manufacturers. Is this a necessary thing to do with 5870s in general? All 5870s are x16 by default and are a fairly popular board... |

Let it get into your OS and see if the card is identified.
That was the other problem... when I did get a boot screen showing and loaded ubuntu 10.10... I could only find 2 of the 6 cards... Might this have something to do with the fact that there is only 4GB of installed ram on this machine? |

I am having a hard time setting up my first multi GPU system here... I have 6 x 5870s (all different brands) all plugged into one MSI 890-FXA-GD70 with a PCIe x1 extension cables that have been modified by myself to accept x16 sized cards. When they are all plugged in to the board directly, and I plug a video cable from my monitor into one of them.... I see the boot screen and the operating system loads... When they are plugged into the board with the modified x1 to x16 cables...you cannot see any video through them... Any ideas?! EDIT: - I am running ubuntu 10.10 - will update as I figure things out! |

Probably cheap parts. I have the exact same problem  |

Instead of buying 4 5850s... why not simply buy 1 5970 for $500 used and maybe buy a $70 Mobo + CPU combo...
If you are going to create a "farm" then you will require a motherboard with multiple pcie slots which will cost multiple hundreds of dollars... just for the motherboard.
Because 1 5970 = roughly 550 MH/s, and 4 5850's = roughly 1000 MH/s. Motherboards with 4 PCIe slots can be had for $140. In fact, I priced out an entire base system (no video cards) capable of running 4 video cards at $397. So about $1000 in hardware would be getting me 1000 MH/s. You will need to buy some extension cables for those 4 cards probably since they will be too close together on the motherboard by itself. (They would get too hot side by side.) I will post pics of my setup in another thread I have going once mine is up and running. |

If I saw an assassination market using Bitcoin, I think I'd contribute to that effort myself, though I know saying that won't win me any points here.  EDIT: Just to be clear, I mean I'd contribute to the DOS effort against such a thing, not to the assassination market! You get points from me. There are a lot of extreme ideologies thrown around on the internet without regard to their practical application. I'd sink a good ship to prevent it from being used for evil any day, and I think anyone who supports the freedom for assassination markets to exist "on principle" should be made to be present during the event--after spending an hour talking with the person before and then having to sit alone with them in a room after. Then they have to explain their principles to the person's family. And raise their kids. What if the CIA put hit out on Ghaddafi in bitcoins? Where would that leave all you holier than thous? How did they pay to have Saddsam Hussein offed anyway, your taxes, in USD to hired guns most likely. FFS how sanctimonious are you going to get on us. What are you smoking? Saddam Hussein was hung in front of the world to see. They had an in court trial and everything. He was convicted of war crimes and hung. |

You would probably offend a large portion of the USA with that slogan. Probably not the best idea for promotion techniques.
The USD is not backed by "Gold".
You're right. It isn't. I originally said "The USD is not backed by God" :S What is going on here?! |

Ho-lee-crap!

CIA will put a bug in Gavin's house, tap his phone, and attach a GPS to his car. They goal is to find out who Satoshi is. Beware!!!
Lol, stop trying to scare our fearless leader. He's fearless. Congrats on the invite Gavin. This looks like it could be quite a big step. |

I made the mistake of upgrading to Ubuntu 11.04 and can't seem to get the graphical client running. Neither the released binary nor the binary I compiled myself will show the graphical interface. The debug.log file indicates that at least the IRC communications are working.
Has anyone been able to run the graphical client on 11.04?
Perhaps you need to re-install...  The bitcoin client works on virtually any stable linux version... No matter what "release". |

If you can divide each bitcoin up to 8 decimals -> smallest amount is 0,00000001. You can have 21000000 / 0.00000001 = 210 000 000 000 000 pieces of valid bitcoin amounts. According to this article http://uk.answers.yahoo.com/question/index?qid=20100813041446AAWsYaP there is probably $40 000 000 000 000. So there is 5,25-times more bitcoins than fortune worldwide. I think humankind should be able to work with that. Except that you can divide dollars into cents... |

as a non hacker investor in BTC, i am tired of hearing laughing and joking about how drug dealers and gangs will most definitely use BTC to move money around the world to facilitate their illegal activities. Hive 45 had 2 jokers laughing and joking about using BTC for assasinations. i'm sorry, civilized ppl just don't talk like that. if this becomes the case, BTC may be doomed in the long run to function as a new currency to replace the USD which is what i presume most of the ppl on this forum want. i know i sure do and now i have an invested interest in making this so. i would like to use this thread to develop ideas about how this activity might be prevented. i don't want to hear comments about how it is inevitable, can't stop it, its gonna happen no matter what type comments that are often accompanied by a veneer of glee. this is serious business and i have BTC to protect; so i'd like to hear productive ideas about how this can be accomplished. if everyone believes its impossible then fine, i get an empty thread.
To prevent money laundering, all the government(s) must do is legalize and control all forms of business. Thus giving the "criminals" no money left to launder. |

Did you lose 10khash/sec or 10Mhash/sec?!
10khash/sec would hardly be noticeable.

Tried it.
Free tier will give you ~3-4 MHash/sec after the first minute or two.
thanks for the feedback. Do you get that ~3-4 MHash/sec 24/7? Not a lot really I guess. If my maths is correct at the current difficulty of ~92000 you would only make on average ~0.03 - 0.04 BTC per day with this setup (assuming getting 3-4Mhash/sec 24/7) thanks again. Woops, please allow me to re-phrase that. You will get about 3-4 KILO hashes per second, not mega, so like a few thousand hashes per second, that's it - on the free tier. It's because you are only allowed "bursted" CPU cycles on the free tier. In other words... you can use the free tier kind of, for a short while, and then get throttled within 1-2 seconds. Can't really complain for free though. |

Is it possible to run 4 seperate miners for my 4 x 5870 setup WITHOUT the ubuntu desktop running?
For example, right now when I run 4 GPUs mining at once on one machine, I open up 4 terminals and enter the appropriate d 1, d 2, d 3, etc commands....
How would I open up multiple terminals or run multiple instances when only running the all black console screen?

So far as I know, 5970s will work for hashing with x1 connections. I am attempting to set up an almost identical rig right now. Will post pictures soon.
