http://setiathome.berkeley.edu/workunit.php?wuid=1923735966 It's an invalid result. Much like the other 146 on your host. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

yes but does it not take 3 to find consensus looking at that wu we both have the same outcome 3 spikes the other invalids are the same odd thing I came down with a bad case of i don't give a crap |

look at the results what i'm saying is exept from teh ones that ended in error because the card crashed there is a bunch of em that did finish correctly with same result as other machine and 3rd party not even started to crunch it how can it be invalid with 2 computers having the same result and how can it be marked invalid without a 3rd machine I came down with a bad case of i don't give a crap |

same here same result as other machine yet i'm invalid http://setiathome.berkeley.edu/workunit.php?wuid=1923735966 I came down with a bad case of i don't give a crap |

yes couple hours ago when i noticed it I came down with a bad case of i don't give a crap |

funny thing is it says device 1 which is the secondary card which i swapped as soon as i saw the errors now the new card is doing the same aperantly which is pretty much impossible EDIT I stick teh card in question in a spare machine i got and see if it does the same crap there but i doubt 2 cards are bad I came down with a bad case of i don't give a crap |

hmm it seems to have stopped magically the invalid count is going down this is just too weird EDIT Maybe i spoke too soon I came down with a bad case of i don't give a crap |

You are still getting invalids off that PC, this is classic symptoms of a very heavily overclocked card that has been taken beyond its limits. The latest report shows it to be clocked at 1500MHz against the (Nvidia) stock of 1000/1075MHz. Even with water cooling that card is going to be right at the limit for calculation - it may be "perfectly fine" for doing graphics where the odd wrong bit is undetectable, but calculations will pick that bit up and the result will be "wrong".

Having the same number of each type of signal as your wingmate does NOT mean the results are the same, especially when comparing a stock app with an Anonymous Platform app, or a CPU vs a GPU. Differences in the individual apps, such as signal thresholds, can cause differences even if the number of signals found is the same. You have to look at the actual result file.

Geesh, just back off your clocking to 1000. Overclocking works for video (where a few artifacts don't matter) but for science it doesn't work. Just try it for 2 days. |

doesn't evga's webpage say 1140 base clock and 1228 boost clock? |

the card is set to defaults it is what it is it was fine for days until earlyer today only thing that changed is i installed latest boinc yesterday morning I came down with a bad case of i don't give a crap |

It actually started to through invalids at 5:06 on the 5th of October. The trouble is hardware faults do occur, and they do occur more frequently at higher clock speeds and temperatures - and you are running that card way beyond the chip designer's specification for that chip set. EVGA have decided that a batch of chip sets are OK for these increased clock speeds (and thus thermal stresses) that they see during their screening process, which is probably representative of gaming, but not 24/7 computing. Expose these chip sets to 24/7, full speed & power computing then they will degrade much faster than they would at their designed power & speed.

Expose these chip sets to 24/7, full speed & power computing then they will degrade much faster than they would at their designed power & speed. With two cards in the same case, one usually runs hotter than the other, unless the card cooling system (especially fan exhaust) is very carefully designed. If the card suffering most errors is the hotter one, you've found another warning sign. |

the stock clock is actually 1379 i just looked Where did you "just looked"? When others say to you "stock clock", defaults, "by spec" - they mean NVIDIA When you say the same - you mean "by EVGA" And EVGA (as most card manufacturers) do "factory Overclock" (to impress gamers, benchmarks and sell more) Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |
