I have a WU with Residue 0000000000000001. The WU was accepted.
What does that mean?

Thanks Crun-chi!
I used the search function to see if somebody asked that question already but i could not find your post... :-)
edit: ah, the search is only for the last 30 days if not specified differently |

Unfortunately it means one of us is wrong. Looks like we need a wingman.

What version of LLR do you use ?

I use PRPNet version 5.2.2 on Windows 7 64bit.
I checked all my logs and it seems that this happened only once so far. |

There's at least one result here with a 0000000000000001 residue. In that case there were a lot of rounding errors and the result was not valid. There were something like four non-matching residues and I ran it manually myself out of curiosity. I matched one of the normal-looking results. |

I agree with Gary's result.
Meilljo, can you try running the test again on your machine to see if the bad residue is reproducible? If so, then there is something that should be investigated, if not then it's just one of those random things that should be found out whenever a range gets double-checked.

This can happen if you overclock your machine of if for some reason it overheated. You might want to clean the inside of your machine to remove dust. |

ok, now i got the same result as you:
\PrimeGrid\PRPNet 5.2.2 - CPU\prpclient-1>llr.exe -d -q"211195*2^3141184+1"
Starting Proth prime test of 211195*2^3141184+1
Using all-complex AVX FFT length 288K, Pass1=128, Pass2=2304, a = 3
211195*2^3141184+1 is not prime. Proth RES64: 19F44012DA6142BB Time : 5726.308
sec.
Probably it was an OC problem. I'll downclock it a bit...
Thanks for the help! |

A word of warning. If you overclock and an error occurs (like this one in this case), you are more likely to miss a prime than find a prime. If only double-checking were turned on... |
