can you tell me 156Mhash/s how many shares/hour(average, minimum?) should produce - please with formulae :)
I'm a bit lost as I don't run 24/7
The expected generation output, at 156000 Khps, given current difficulty of 55590.23763914 , is 2.8226040045 BTC per day and 0.117608500188 BTC per hour (actually 3% less because of fee in Proportional mode). And this difficulty may change tomorrow. Use online mining calculator :) The average time to generate a block solo at 156000 Khps, given current difficulty of 55590.23763914 , is 2 weeks, 3 days, 17 hours, 8 minutes, and 21 seconds Multiply number of shares per minute by 71 and you may possible get your speed in MH/s. paulofisch gets 20 per hour, and (20/60)*71 = 23 MH/s Calculate backwards if you want to get shares/minute for given speed. |

I'm useing poclbm under Ubuntu with one HD5970 and I’m getting always the following error message after starting mining with the second core (./poclbm.py -d 2):
”Verification failed, check hardware!”
(With the first GPU core (./poclbm.py -d 1) everything works fine.)
Is my GPU damaged or is this a software/setting bug?
How could I test under Ubuntu that both of my GPU cores are ok? You should disable Crossfire or use old version of poclbm on Windows. |

It's horrible and definitely not healthy for the card Looks like you have very bad ventilation in your PC case. Try removing the cover. |

I doubt... çàâèäóé ìîë÷à è ñïåðâà äîáåéñÿ envy in silence and prove that you can do it better 8*6990 would have been godly for mining It will give 5.1 * 8 TFlops = 40.8 TFlops, 5,28 GHash/s the whole network is 580 GHash/s - bitcoincharts.com 10 500 000 BTC per 4 years = ~7200 BTC/Day 7200 * 5,28/586 = 64 BTC / day ~220 days to cover costs (without electricity) Ïîñòåñíÿëñÿ áû óæ ïîçîðèòüñÿ. If only this can work without overheating in first couple of minutes, it would be ~4.32 GH/s. (8 x 5970) ~55.7074180016 BTC per day at next difficulty (after tomorrow). Let's assume that difficulty will increase by 30% every 10 days for easy counting. 557 + 340 + 273 = 1170 BTC first month 190 + 133 + 94 = 417 BTC first month 66 + 46 + 32 = 144 BTC third month. 8 * 300 = 2.4 kW just for the cards * 24 * 30.5 * $0.1 = $175 per month for power, oops, we are not profitable already. |

My balance got emptied but I didn't receive anything, is everything ok?
Open your payments list on deepbit site and check if there was a payment. It should be there. |

Need help from a math wizard. My goal is to make $10000 per year supplemental income by mining bitcoins. My cost per kW is $0.10. What kind of investment do I need to make to create this much money? How long will it take to recoup the investment and start generating income?
Since you are already going to invest, then i can assume that you already know who will buy your mined bitcoins and why. So tell us, when you should sell them and how much USD per bitcoin they will pay you, then we can give you advices on mining. |

So, for those doing a frogger between Prop. and PPS, another thing to consider is that if the rate of block discovery goes down through difficulty or lack of luck, I'm assuming the price in PPS will surely drop anyway in the long term. Currently i'm working on something like mode separation and the third reward option which will make Prop-PPS jumpers safe for honest users. EDIT: So it's someone called "Tyco" who steals all my profit ? |

Geezus proportional is profitable again. It's always the same on average, as i said earlier. |
|
|

well, in the long run you'll get <7% more from proportional, that's what you can expect.
no need to take your hashrate or any imaginary numbers into account.
I would say not true for those with lower hashrates, but could be wrong. Should be true for anyone. Then I stand corrected. Was thinking the chance to miss blocks with lower hash rates might make a difference. If you miss each one of two rounds, then you need ~twice more hashrate. Then you will have, possibly, one share in each round, which gives you twice the reward, just proportional to your speed. |

Would it be possible to get the payouts listed in descending order? (Newest on top)
It's possible, but what is your reason for that ? |
|
|
|
It is (in theory) possible to take an average hashrate (and from extension, average amount of shares of some time) and figure out how much you can expect to make in the long run using the different payouts.

Back on topic; I've found that undervolting is almost never mentioned. The performance per watt seems to be the most important metric, even before the initial investment in hardware. Comparisons are usually topped by mid-range cards, but that's because the high-end cards run at higher stock voltages and frequencies. You can easily double the FLOPS/W by undervolting and underclocking, e.g. with ATI Tray Tools.
Actually overclocking without overvolting can increase MH/W. But undervolting may be more effective. |

Looks like people are still confused with two existing reward distributhing modes, so now i'm working on third one.
Hope you'll like it.

I am having trouble understanding the payment system. I have my automatic payment set to 10 BTC. Wouldn't that make it to where I get my reward when my balance reaches 10 BTC? Currently, my balance is at ~17 BTC. Why hasn't the automatic payment been sent?
As i said some times here, in main post and on main page of site - during beta stage payments are processed daily because of additional checks :) And one other reason: MANY people set their threshold to 0.01 BTC and tried even smaller numbers, so if i would pay every hour, it will flood the network with lots of low-priority transactions, which is not nice. Just forced one payment for someone with ~17 BTC. |

I am using my GTX 480 for mining and it's crunching at about 106 Mhash/s. Is it better for me to be on Pay-Per-Share or Proportional payout?
I would sell it and replace it with an ATI. You are using roughly ~500w @ full load. With 80% PSU efficiency you're pulling 600w from the wall. 600w/hour * 24 hours/day * 30 days = 432 Kwh and at $0.10/Kwh, you would be paying $43.20 a month in electricity and pull in about 57.5 BTC per month or $52.33 a month at current difficulty and current Mt.Gox market price, netting $9.13/mo. I don't like using ATI cards, their driver support for Linux is not very good. Only if mining or other integer stream processing is not your main goal. ATIs are many times faster than nVidia in mining. |

1. When I switch to PPS in the past my credits would accumulate every minute or two -- just ran it for 5 minutes and no change. Yes, I know the disclaimer says updates once per hour but that isn't how it was working on Wednesday.
Fast update was enabled only for testing. Now it's once per hour, as it should be. You haven't noticed change in the disclaimer :) 2. We are now past 8 hours without a block!
I know slush and tycho discussed slush's pool having issues (with bitcoind) as it neared 30GH/s. Hoping that isn't the issue here!
No, everything is working as it should. EDIT: Today slush's pool had at least two blocks that took more than 200 000 shares each, so it's still perfectly possible unlucky round. |

is the server down right now?
No. |

UPDATE: - Now you can set your timezone, all dates will be shown with your local time.
- Login box is now hidden when you are logged in.

Tough day for Deepbit - just 9 blocks ::) It should average out back to normal. Currently we have about ~52 000 shares per block at current difficulty which fits perfectly. |
