A lot of people here wont mind, but I think the general population does.

Yes, Bitcoin is a young and small market and, like any young and small market, you can move it if you have enough money. With time and more acceptance this will change and it will be more difficult to move by one person.
Thanks for sharing your insights.

I'm not sure what you mean...? AMDOverDriveCtrl will show you the current voltage, but it won't show you any sort of power consumption or separate voltages for GPU and Memory. Yes, AMDOverdriveCtrl lets you see an set the voltage, but to know the consumpton of a card (and anything) you need the voltage and the current. I know some linux tools show the current and the rest of the temperature sensors. I would like to access that information in linux. |

I dont see nothing wrong, but there is something weird:
DISPLAY=:0 aticonfig --od-enable --adapter=all
Why adapter=all? You want adapter 0 right? Also, once you do od-enable once you dont need to do it again, ven after rebooting the computer. I think you can delete that line. Try without it, maybe it does a difference although I doubt it.

I have significant experience mining with these cards so let me help you out and save you some time.
The 5870 is an awesome card. You can mine stable at 415-420mh/s
use MSI Afterburner and overlcock it to 980 core and 180 mem
set the fan at 75%
I have two that have been hashing for months without a crash or a reboot.
The 5830's are a little slower but you can get around 280-300 mh/s stable
clock these also at 1000 core but they like the 300 mem clock sweet spot
also set fans to 75%
I have two of each.
I also mine with two 6870's
they love to run with high core clocks
get em both at 1025 core and 180 mem
give me 295-305 mh/s all day
Hope I could help. What about power consumption? |

Im not completely opposed and I see that what you say makes sense, but the italians had a very inflationary currency and they exchanged 1000 liras for 1 dollar and the dollar went ok...
And about moving the decimal, how would you do such a thing? You would need everybody or at least a big majority to agree. It would be the same as chanign the rules. The danger is a split of the chain and having two competing bitcoins, which in my opinion would take credibility away from bitcoins at this moment. On the other hand, it its done successfully and the community shows that its capable of such transitions it would be a big boost of confidence since it would shut up a lot of complaints. Its risky.

You didn't address my points at all, it seems that you are assuming changes within a bitcoin-centric economy. In order for people to get into bitcoins they need to actually buy bitcoins with dollars (or whatever). People are not willing to pay $100 for "$1", even if it is a super magical internet dollar that is worth $100. People are willing to pay $10 for 100 internet dollars. This is what I mean by human psychology. We need for people to be able to put $20 in and get 87 bitcoins to spend, rather than getting 0.87 bitcoins. It makes a huge difference.
As for math, people really cannot compare 0.00006 and 0.0001. Most people would tell you that the first number is bigger. If you did a poll you would get maybe 10% saying that he second is bigger, 20% saying that the first is bigger, and 70% telling you that they don't know and that they HATE math.
I misunderstood what you were saying. What you explain here is easily solved by talking of milibitcoins or microbitoins. So you get 50 mbtc (milibitcoins) with 1 dollar. The official client can be changed to show milibitcoins also (or make it optional, but show milibitcoins by default). |

You should post the script so we can give you an opinion.
Also, did you try to launch the cards in different order? Are you sure its not a particular card failing, the one you launch last?

I was thinking on using them to buy stuff. Am I that weird?

You are completely discounting human psychology and massively over-estimating the mathematical ability of mankind. According to the experiments of behavioural economics people is sensitive to transitions in the value but not so much to nominal value itself. For example, in inflationary environment people will prefer a rise of 2% with the CPI going up a 4% (your real wage goes down 2%) than no rise with a CPI of 1% (your real wage goes down 1%), because people can not control the CPI so they try to stay ahead by demanding the maximum they can get. But people adapt to a nominal price level quite quick. For example, 10 years ago your wage and the prices were way lower, but people have adapted to the new prices and see them as normal. |

So how much does OC'ing cost in terms of lifetime? Seems to yield an extra 10% in hash rate, is it worth it?
It can be significantly more than 10%.... Stock I was at 292 MHs with poclbm. OC'd I'm at 392 MHs with phoenix. That's some 30%! Over-time-damage can be a gamble and often you can damage more than just your videocard. Cheap components on motherboards and PSUs will go up in smoke sometimes as well as getting a general life reduction. Yeah, the 5870 does around 350 Mh/s without overclocking and 445Mh/s OC (maybe others get even more). If you lower the memory speed, keep the voltage low (I have 1'080 while maximum non-OC is 1'136) and the heat is low, why should it be a problem? |

Get AMDOverDriveCtrl and see if it will let you go below the floor set by default.
In my experience, on 5830s and 5870s, it will allow you to set a memory clock as low as 150. No flashing, etc, required.
Do you know how to measure the consumption of the cards in Linux? I tried radeonvolt, but it does not work on my 5870 card. |

Guess you didn't read. I understand "union" clouds people's minds when even read. Then you dont want to create a union like the op, you just want to distribute information. And we are in agreement that the information could be useful and create some difference in the market. But its very different of what the op proposed. |

Im getting 445 Mh/s with 5870 @1005:340 (one needed 350, dont know why) with a very small overvolting with voltage between 1'080-1'075 (depending on the card). Using phoenix, phatk kernel with 2.4 SDK in Ubuntu. The card with higher temperature is always under 70º, usually around 60-65 (no computer case). Fans at 90%.
I have gotten some to over 460 Mh/s with more voltage and more core speed, but they crash after a while. Stable 445 Mh/s is the max Ive gotten.

Im not sayinv regulation, more like a voluntary custom for exchangers.
And what happens when it goes down on a Monday? Do they stop Monday trading too? How about no trading on the third full moon after the second Tuesday of October on even-numbered years? Why don't they just ban selling? Then it'll only go up! Boom/bust is a reality of any market in which humans are involved. The psychology is always the same...  More serious version:  Learn it, understand it, control it, and profit from it. This is not true. There are times that given the legal framework are remarcably stable. |

I think the bitcoin economy is really too volatile for giving out loans. Only about 50BTC are generated every 10 minutes. With rapid deflation you would need negative interest. The problem is that it is more profitable to buy and hold, rather than giving a negative interest loan.
For planning, I am using the 30 day weighted average price. I am assuming that should even out most of the volatility. You can pay interest without problem in a price deflationary economy. You just need to invest the money in a business that generates income (which is the point of a loan). That is the problem on why nobody is lending in bitcoins right now, because its hard to generate a business that generates income in bitcoins. |

I think its a big mistake to compare Bitcoin with stablished markets. Bitcoin is young and small, its going to be very volatile, both up and down and its going to beahve like a young market not like a big old market. Nobody should be surprised at the events of the last days and weeks.

Im sure the market that is supplied by the miners will care. I didn't suggest a union merely educate folks on how their selling habits can effect the market. Im not about controlling anyone and always hope individuals will be individuals but prefer to see intelligent one's. But voluntary unions, that is non-government unions, are not inmoral, they are just a bunch of people voluntarely agreeing to comply with a set of rules. There is nothing inmoral in that. The problem is that they dont work in price fixing, as history shows. They might obtain some small victories, but they dont last long. |

What day of the week it happened on has jack all to do with why it happened.
Why are people (even in real markets) always concerned with trying to prevent parabolic falls, but no one cares about preventing parabolic increases?
For once, I have to agree with you. Im happy bitcoins went down. It was not normal. But it has to do with the day because the weekend certain services are closed and can affect the Bitcoin market. I still think it should be open 24/7, but at the end its the decission of the exchanges. |

My post is a negative warning, with a positive message for Bitcoin Health.
Why can't the market be more "sane", going up so fast is not a good sign since a strong pull-back is more likely. Slow and steady is better for investors and Bitcoin. At this rate it could be back to $10.25 today's low in < 60 minutes.
Bitcoin is a young project and a small market. Volatility is spected, it should not be a surprise. Only with time and more acceptance will volatility go away. |
