Hey everyone I've been trying to mine for a few days now with no success. I have 2 Radeon 5830s, cgminer 3.7.2, AMD AAP SDK 2.8, Catalyst 12.8 and a fresh Ubuntu 12.04 install. Here is the cgminer output:  As you can see it's communicating with the pool Okay, it's heating up the cards but not accomplishing any useful hashing. You'll even see some of the shares are "above target." Is there a way to monitor what cgminer is actually doing to help me determine what is going wrong? Thanks! * If you ask me what version of something I'm using please explain how to check |

A friend of mine just launched a knife store that accepts only bitcoin. You can support him simply by visiting and taking a look: http://www.knives4bitcoin.com |

Hey there. I went ahead and signed up. I noticed that the pricing when you create an account vs. when you upgrade is different. You should check that out. It turns out I picked the right package.
I would like to setup multiple text-message destinations; to more than one phone. If that's possible please send me a PM. I've got about 30 GPUs and I'd like to cover my bases by letting two people know when something goes wrong so that a restart can happen ASAP.
Thanks!

I have 30 workers, there's no way for me to test this out for a month before committing the most expensive package? I don't see the value in monitoring one graphics card, even as a test. Why does it cost more PER worker? You only have to access the API page once every 20 minutes and store the data for each worker.
The spot pirce is still based on MtGox ? Why isn't it based on TradeHill?
I would be happy to evaluate this and share what I think about it if I could monitor my entire network for a week or two.
Thanks

We're running 2 machines per outlet. I used a KilloWatt to measure amps, 5.35. So that's 2 per 20amp circuit to stay below 16 amps We ran 7 additional circuits into the room :p |

I mean to say, the reward is not going up in the display. I saw another thread and brought it back. They said it was a display only issue but also said it was solved about 2 hours ago.

Block share counts, times, and rewards are now back in order. There was a bug in the way I handled the list of the block generations for the 3 servers, and the EU server was overriding the US East server's list, rather than adding onto the main list. As usual, this only caused a temporary problem in displaying accurate stats. The backend is very strong and is never overwritten by the frontend when performing reward calculations, so your historical data remained safe for recalculating the rounds.
I'm still looking at 0 rewards for 4-6 hours, maybe more. Is this issue display only or do I need to switch back to deepbit? I'm contributing around 6Mhash/second |

I see the message: "Servers are overloaded. 800~900 GH/sec growth was not expected. More servers coming online this week."
I also noticed I haven't received any reward in the last 4-6 hours. Is there anyway to get around this? I don't see anymore information anywhere else.
Thanks

I have the same issue with Phoenix, except they don't always come back online. Does anyone have a solution?

I put together my own Google spreadsheet to examine whether it makes sense to add to what I am currently using to mine, and the numbers keep looking bad. E.g. for a triple 5830 system: Days to next reset:5.0, based on http://blockexplorer.com/q/etaDifficulty of next reset: 513600, based on http://blockexplorer.com/q/estimateDays per difficulty increase after the next one: 8 Difficulty increase factor after the next one: 1.3 (30% average increase) Watts: 550 $/KWh: 0.12 MHash/Sec: 840 (3 * 280 per 5830) $/Bitcoin: 10 Running the above numbers, on August 18 the electric cost exceeds the generated bitcoin value. Total income at that point (assuming selling bitcoins at $10 apiece) is $492 - putting together a 3-way 5830 system for $492 is pretty tough (used parts maybe?) Are other people using more optimistic numbers? How about this, at no time in the last year has bitcoin cost more than 1/4 of its exchange value to generate based on electricity. It's currently at about 1/17th the value to generate (this fluctuates over time and just left an all time high). People have been doing calculations like you have for months saying the same thing you have |

The 20,000 is probably pretty close to accurate, so if the 16M number sold is accurate why has there been such an impact on the video card market? You can't reliably find 5850s, 5870s, 5970s, or 6990s in stock anywhere, and even 5830s are going. If we're only .1% of the market, it shouldn't have had that big of an effect. Does that mean there is like 50k G/hash in cards purchased recently and still waiting to come online? It's possible, and I know I'm part of it since I bought 27 cards in the past week  Is the 20,000 miners or cards sold to miners? I personally have bought around 30 cards so far, other people who look at this as an investment are buying 5-10 without much hesitation. How many of the 16,000,000 cards are sitting in stores or in prebuilt computers waiting to be sold? |

A simple estimate of the bitcoin community puts miners in the roughly 10-20,000 range. New card sales are likely less but even assuming an optimistic estimate, we'll say 20,000.
In the first 9 months after the 5xxx series was released, AMD sold 16million 5xxx chips. 20,000 / 16million = .1% Bitcoin is a drop in the bucket at the moment. I'm glad people are being optimistic about bitcoin, that's what it needs, but really let's keep things in perspective.
Screw bitcoin :p I'm in it for the money |

Not to rain on anyone's parade, but I have (2) 6870 cards -- a Sapphire and an XFX -- and the XFX doesn't overclock as high, runs hotter, and the fan is MUCH, much louder. You can hear it over everything else in your room. There are many threads on the 'Net about how to cool them -- mostly desperation. I re-applied arctic silver paste which helped a BIT, but it's only 5 degrees cooler. The fan is still loud. I borderline regret I bought it.
With what I know today, I'd pay $20 or even $30 more for an equivalent Sapphire card over an XFX one.
Just my personal experience.
Matthew
Thanks for the info. I'll have 1/3 Sapphire and 2/3 XFX in my next setup. I'll keep any eye out for cooling issues with these cards. |

so wait will my 5870 do good since ive been reading that 5830's are like the best card to mine?? sorry im a noob and i didnt mean for my 1st post to be this  i was actually going to post in a different thread but this one caught my eye  The 5830 is the best bang for your buck RIGHT NOW. I don't know what you paid for your 5870 but it's much better for mining than a 5830 ignoring cost |

You may not be so glad in 10 days when you finally get your rigs running and difficulty doubles  I did all my calculations a week ago and things look good, prices have more doubled since. bring on the difficulty increase :p |

That's good to know. When I put them in my cart it made it look like you could only use the rebate once. -- "NOTICE: Limit (2) rebates per person, billing address, company, or household." I suppose you could get around that pretty easily |
