like the topic say ;) i joined up cosmology some days ago. i got work and start to calculate the data i got. for some reason unknown to me my system get hit by a total freeze after some time of calculation. only cure is a hard reset. after rebooting boinc shows up my unit lets say at 35% this isnt changed for about 10-15 minutes, then the current work restarts from 0,00% again.from the 4 workunits i was able to finish i had 3 total system freezes. so i think i have a problem here ;) my system: ubuntu linux 7.10 x86 cpu: amd64 3500 the whole system is in no way overclocked camb version: 2.04 boincmanager 5.10.28 (from boinc download page) as i cant find any logs or any other stuff what could give me a clue what happens, i ask if someone has seen something similiar to my problem. for now i suspended cosmology for good.

I would start by running memtest on your memory. You didn\'t say how much mem is installed either.

installed ram is 1gb and memtest seem to like the ram.

This could be due to any number of reasons - one possibility is thermal/cooling/ventilation problems. Ben Creator of Cosmology@Home |

The moderator, Ageless, recommended this test: OCCT Supposedly, if it will run this without errors, it\'s clean. Not sure if that\'s true, but it does put CPU, RAM, etc. through the wringer. I\'ve tested it. Safe to run, even with scary web site. :D |

The moderator, Ageless, recommended this test I did? It\'s the first time I\'ve seen that tool. I think. ;-) |

The moderator, Ageless, recommended this test: OCCT is an excellent \"stress tester\". I use it on all my crunching rigs and run it for 1.5 hours. If it passes that, it will crunch most anything stable. mike 229.80Ghz Home Owned and Operated Cruching Power Operating at 45% currently |

The moderator, Ageless, recommended this test Actually it was that other cpu basher, tutta55, who recommended OCCT for stress testing. :p I only used it on Windows, though. Not sure there\'s a Linux version. BOINC.BE: For Belgians who love the smell of glowing red cpu's in the morning Tutta55's Lair |

Sorry, all you mods look alike. LOL I knew it was ONE of you! Not sure there\'s a Linux version. My bad,again. Thought he had Linux, too. Looks like not. |

You might try using transcode to encode some gigantic video at some a ridiculous quality. Other than that, I\'m not sure of any crazy benchmarks for Linux. Scott Kruger Project Administrator, Cosmology@Home |

Other than that, I\'m not sure of any crazy benchmarks for Linux. http://users.bigpond.net.au/cpuburn/ has both Windows and Linux versions. Note: also does error checking on results, which most burn-in programs do not.   Boinc Button Abuser In Training >My Shrubbers< |
