Hallo! I allways get 80 task only for stock on my computer. As I do crunch 129 +/- 17 tasks/day in the mean averaged over the last 16 days, that will last only for about 15 h of continously crunching, in case there is a breakdown of the data server or the internet connection. In my account I did set up to get at minimum a stock for 2.5 days and a max. of 3 days. That would result in a stock of 322 at minimum and 387 tasks at maximum. Why don´t I get them ??? Kind regards and happy crunching. Martin |

That's not specially for you, we all get max. 40 tasks per GPU, for high-end ATI cards that's a bit more than half an hour of work. So with 15 hours you have a quite large cache ;-). If you don't want your GPU to idle in case the project has some issues with servers, you should configure a backup project for it (0 resource share). |

What's the limit for CPU only machines? I'm running one CPU on a Surface Pro and my max seems to be 3 tasks. Which can be as little as 2.5 hour of crunching. |

My high end 'AMD' card, Radeon HD 7950, completes 40 tasks in ~13 minutes. 20 seconds per task. A low end AMD card, HD 7770, completes 40 tasks in just ~40 minutes. Therefore, you are REALLY off on how fast AMD cards are. |

Then again, I suppose 7770 proprietary drivers have DP processing speed cut by 1/4th, so a 7770 would take 4 minutes per task instead of 1. The moral of the story is don't use low end hardware on Milkyway. |

Therefore, you are REALLY off on how fast AMD cards are. My post was from 30 Jan when we had about 2x longer WUs than now, so at that time it was not that much off. Also "high-end ATI cards" include not just the fastest GPU. I don't have such GPU myself, so of course I don't know the exact times, but that was also not the point of my post. |

Therefore, you are REALLY off on how fast AMD cards are. > HD 7990 is enthusiast > HD 7900 is high end > HD 7800 is mid end > HD 7700 is low end >> HD 7950 is the slowest high end AMD card I'm not sure where you are coming from. Also, don't call them ATI, they are AMD cards. ATI hasn't existed in years. |

According to Wikipedia: Entry-level (low-end): 73xx - 75xx Mid-range cards: 76xx - 77xx High-end cards: 78xx - 7970 GHz Edition Enthusiast cards: 7990 Anyway, the exact runtimes are completely unintresting in this thread hence I didn't even bother to find it exactly out for that posting above, just written something, that was going to be about right (and probably was for HD6900 series cards and the WUs we had at that time). And I think everybody knows what ATI cards are. |

According to Wikipedia: And everybody knows that ATI cards no longer exist and haven't existed for 7 years. They are AMD cards, not ATI cards. Radeon HD 6900 series is over 2 years old at this point. I've owned this 7950 for more than a year. Wikipedia is not a reliable source. If you are familiar with the naming scheme AMD uses: x1xx - x6xx = OEM-only x7xx = low-end x8xx = mid-end x9xx = high-end x99x = enthusiast End of story. |

End of story. For me it was when I answered the initial question on the 30th January, but few months later you wanted to discuss such completely irrelevant (in this thread) things like which cards are high end, how long exactly they need to process 40 WUs and wether is it OK to call them ATI or not. |

It is perfectly relevant, and the date of posts does not matter at all. Hardware is no different today than it was then. It isn't okay to call them ATI and it never will be okay. Stating that a high end AMD card takes a ridiculous amount of time compared to the reality of ~18 seconds per work unit spreads misinformation. |

~18 seconds per work unit spreads misinformation. That's valid only for the current WUs, we had here up to 3-4x longer WUs (~320 credits per WU), so this information will be outdated as soon as we get other WUs. But feel free to update this thread when that happens, I got other things to do. |

Hi, from may 8 until today i didn't receive any credits although milkyway runs on a daily basis. Anyone else having the same problem? greetz |

You were receiving credits on most of the days, however I don't know how much you were crunching Milkyway, you have just 42 tasks in your list ATM and only 3 of them in progress, that's very little actually. Looks like you were crunching mostly Einstein in the last days. |
